To our stockholders: 

LETTER TO STOCKHOLDERS 

KLA‐Tencor delivered strong operating and financial performance in fiscal year 2017. 

Total revenues in the fiscal year were $3.5 billion, net income was $926 million, and diluted earnings per 
share was $5.88, all record results for the Company.   We ended the period with over $1.8 billion in 
backlog, an all‐time‐high. 

We generated $1.1 billion in operating cash flow, and ended the year with just over $3.0 billion in cash, 
cash equivalents and marketable securities. In keeping with our ongoing commitment to reward our 
long‐term stockholders, we returned $344 million to stockholders through our cash dividend program 
in fiscal year 2017, which included the effect of a 4% increase in our regular quarterly cash dividend level 
from $0.52 per share to $0.54 per share, announced in October 2016.  Additionally, we sustained our 
market leadership and strong pace of innovation by maintaining a high level of investment in research

Industry 

General Background 

KLA-Tencor’s core focus is the semiconductor industry. The semiconductor fabrication process begins with a bare 
silicon wafer—a round disk that is typically 150 millimeters, 200 millimeters or 300 millimeters in diameter, about as thick 
as a credit card and gray in color. The process of manufacturing wafers is in itself highly sophisticated, involving the creation 
of large ingots of silicon by pulling them out of a vat of molten silicon. The ingots are then sliced into wafers. Prime silicon 
wafers  are  then  polished  to  a  mirror  finish.  Other,  more  specialized  wafers,  such  as  epitaxial  silicon  (“epi”),  silicon-on-
insulator (“SOI”), gallium nitride (“GaN”) and silicon carbide (“SiC”), are also common in the semiconductor industry. 

The manufacturing cycle of an IC is grouped into three phases: design, fabrication and testing. IC design involves the 
architectural  layout  of  the  circuit,  as  well  as  design  verification  and  reticle  generation.  The  fabrication  of  a  chip  is 
accomplished by depositing a series of film layers that act as conductors, semiconductors or insulators on bare wafers. The 
deposition of these film layers is interspersed with numerous other process steps that create circuit patterns, remove portions 
of the film layers, and perform other functions such as heat treatment, measurement and inspection. Most advanced chip 
designs require hundreds of individual steps, many of which are performed multiple times. Most chips consist of two main 
structures: the lower structure, typically consisting of transistors or capacitors which perform the “smart” functions of the 
chip; and the upper “interconnect” structure, typically consisting of circuitry which connects the components in the lower 
structure. When all of the layers on the wafer have been fabricated, each chip on the wafer is tested for functionality. The 
wafer is then cut into individual chips, and those chips that passed functional testing are packaged. Final testing is performed 
on all packaged chips. 

Current Trends 

The semiconductor equipment industry is currently experiencing growth from multiple drivers, such as demand for 
chips providing computation power and connectivity for Artificial Intelligence (“AI”) applications and support for mobile 
devices at the leading edge of foundry chip manufacturing. Qualification of early EUV lithography processes and equipment 
is driving growth at leading logic/foundry and dynamic random-access memory (“DRAM”) manufacturers. Expansion of the 
Internet  of  Things  (“IoT”)  together  with  increasing  acceptance  of  advanced  driver  assistance  systems  (“ADAS”)  in 
anticipation  of  the  introduction  of  autonomous  cars  have  begun  to  accelerate  legacy-node  technology  conversions  and 
capacity expansions. Intertwined in these areas, spurred by data storage and connectivity needs, is the growth in demand for 
memory chips. Finally, China is emerging as a major region for manufacturing of logic and memory chips, adding to its role 
as the world’s largest consumer of ICs. Government initiatives are propelling China to expand its domestic manufacturing 
capacity and attracting semiconductor manufacturers from Taiwan, Korea, Japan and the US. China is currently seen as an 
important long-term growth region for the semiconductor capital equipment sector. 

Supporting  this  multi-segmented  market  growth,  the  semiconductor  industry  continues  to  introduce  numerous 
technology  changes.  New  techniques  and  architectures  in  production  today  include  three-dimensional  finFET  transistors, 
three-dimensional  flash  memory  (“3D  NAND”);  design  technology  co-optimization  (“DTCO”);  advanced  patterning 
lithography, including self-aligned multiple patterning and extreme ultraviolet (“EUV”) lithography; and advanced wafer-
level packaging. KLA-Tencor’s inspection and measurement technologies play key roles in enabling our customers to develop 
and manufacture advanced semiconductor devices to support these trends. 

Companies  that  anticipate  future  market  demands  by  developing  and  refining  new  technologies  and  manufacturing 
processes are better positioned to lead in the semiconductor market. Accelerating the yield ramp and maximizing production 
2 

 
yields  of  high-performance  devices  are  key  goals  of  modern  semiconductor  manufacturing.  Ramping  to  high-volume 
production  ahead  of  competitors  can  dramatically  increase  the  revenue  an  IC  manufacturer  realizes  for  a  given  product. 
During past industry cycles, semiconductor manufacturers generally contended with a few key new technologies or market 
trends, such as a specific design rule shrink. In today’s market, driven by consumer demand for low-cost electronic goods, 
the  leading  semiconductor  manufacturers  are  investing  in  simultaneous  production  integration  of  multiple  new  process 
technologies,  some  requiring  new  substrate  and  film  materials,  new  geometries,  advanced  multiple-patterning  and  EUV 
lithography and advanced packaging techniques. While many of these technologies have been adopted at the development 
and pilot production stages of chip manufacturing, significant  challenges and risks associated with each technology have 
affected the adoption of these technologies into full-volume production. For example, as design rules decrease, yields become 
more sensitive to the size and density of defects, and device performance characteristics (namely speed, capacity or power 
management) become more sensitive to parameters such as line width and film thickness variation. New process materials, 
such  as  EUV  lithography-capable  photoresists,  require  extensive  characterization  before  they  can  be  used  in  the 
manufacturing process. Moving several of these advanced technologies into production at once only adds to the risks that 
chipmakers face. 

The continuing evolution of semiconductor devices to smaller geometries and more complex multi-level circuitry has 
significantly increased the performance and cost requirements of the capital equipment used to manufacture these devices. 
Construction of an advanced wafer fabrication facility today can cost over $5.00 billion, substantially more than previous-
generation  facilities.  In  addition,  chipmakers  are  demanding  increased  productivity  and  higher  returns  from  their 
manufacturing equipment and are also seeking ways to extend the performance of their existing equipment. 

By developing new process control and yield management tools that help chipmakers accelerate the adoption of these 
new technologies into volume production, we enable our customers to better leverage these increasingly expensive facilities 
and improve their return on investment (“ROI”). Once customers’ production lines are operating at high volume, our tools 
help ensure that yields are stable and process excursions are identified for quick resolution. In addition, the move to each new 
generation’s smaller design rules, coupled with new materials and device innovation, has increased in-process variability, 
which requires an increase in inspection and metrology sampling. 

KLA-Tencor systems not only analyze defectivity and metrology issues at critical points in the wafer, reticle and IC 
manufacturing processes, but also provide information to our customers so that they can identify and address the underlying 
process problems. The ability to locate the source of defects and resolve the underlying process issues enables our customers 
to improve control over their manufacturing processes. This helps them increase their yield of high-performance parts and 
deliver  their  products  to  market  faster—thus  maximizing  their  profits.  With  our  broad  portfolio  of  application-focused 
technologies and our dedicated yield technology expertise, we are in position to be a key supplier of comprehensive yield 
management solutions for customers’ next-generation products, helping our customers respond to the challenges posed by 
shrinking  device  sizes,  the  transition  to new production materials,  new  device  and  circuit  architectures,  more demanding 
lithography processes, and new back-end packaging techniques.

For customers manufacturing legacy design-rule devices, our K-T Pro division provides refurbished KLA-Tencor tools 
as  part  of  our  K-T  Certified  program;  remanufactured  trailing  edge  systems;  and  enhancements  and  upgrades  for  last-
generation KLA-Tencor tools. 

Chip Manufacturing 

KLA-Tencor’s comprehensive portfolio of inspection and metrology products, and related service, software and other 
offerings, helps chip manufacturers manage yield throughout the entire semiconductor fabrication process—from research 
and development to final volume production. These products and offerings are designed to provide comprehensive solutions 
to  help  our  customers  to  accelerate  their  development  and  production  ramp  cycles,  to  achieve  higher  and  more  stable 
semiconductor die yields, and to improve their overall profitability. 

Front-End Defect Inspection 

KLA-Tencor’s front-end defect inspection tools cover a broad range of yield applications within the IC manufacturing 
environment, including: research and development; incoming wafer qualification; reticle qualification; and tool, process and 
line monitoring. Patterned and unpatterned wafer inspectors find particles, pattern defects and electrical issues on the front 
surface, back surface and edge of the wafer, allowing engineers to detect and monitor critical yield excursions. Fabs rely on 
our high sensitivity reticle inspection systems to identify defects on reticles at an early stage and to prevent reticle defects 
from printing on production wafers. The defect data generated by our inspectors is compiled and reduced to relevant root-
cause  and  yield-analysis  information  with  our  suite  of  data  management  tools.  By  implementing  our  front-end  defect 
inspection and analysis systems, chipmakers are able to take quick corrective action, resulting in faster yield improvement 
and better time to market. 

In August 2016, we launched the Teron SL655 reticle inspection system, which enables IC manufacturers to assess 
incoming reticle quality, monitor reticle degradation and detect yield-critical reticle defects. The Teron SL655 introduces 
new STARlightGold technology, which provides a golden reference to maximize detection of defects critical to the mask 
requalification process. 

The  launch  of  the  Teron  SL655  further  strengthened  our  broad  range  of  offerings  that  support  the  front-end  defect 
inspection market. In the field of patterned wafer inspection, we offer our 3900 Series (for high resolution broadband plasma 
defect inspection); our 2930 Series and 2920 Series (for broadband plasma defect inspection); our Puma 9980 Series, Puma 
9850 Series and Puma 9650 Series (for laser scanning defect inspection); our 8 Series systems (for high productivity defect 
inspection); and our CIRCL cluster tool (for defect inspection, review and metrology of all wafer surfaces - front side, edge 
and back side). In the field of unpatterned wafer and surface inspection, we offer the Surfscan SP5 Series and Surfscan SP3 
Series (wafer defect inspection systems for process tool qualification and monitoring using blanket films and bare wafers); 
and the SURFmonitor (integrated on the Surfscan SP5 and Surfscan SP3 Series), which enables surface quality measurements 
and capture of low-contrast defects. For reticle inspection, we offer our X5.3 and Teron SL650 Series products, which are 
photomask inspection systems that allow IC fabs to qualify incoming reticles and inspect production reticles for contaminants 
and other process-related changes. In addition, we offer a number of other products for the front-end defect inspection market, 
as reflected in the product table at the conclusion of this “Products” section. 

Defect Review 

KLA-Tencor’s defect review systems capture high resolution images of the defects detected by inspection tools. These 
images  enable  defect  classification,  helping  chipmakers  identify  and  resolve  yield  issues.  KLA-Tencor’s  suite  of  defect 
inspectors, defect review and classification tools and data management systems form a broad solution for finding, identifying 
and tracking yield-critical defects and process issues. The eDR7280, an electron-beam wafer defect review and classification 
system, utilizes improved imaging and automatic defect classification capability to identify detected defects and produce an 
accurate representation of the detected defect population.

Metrology 

KLA-Tencor’s array of metrology solutions addresses IC and substrate manufacturing, as well as scientific research 
and  other  applications.  Precise  metrology  and  control  of  pattern  dimensions,  film  thicknesses,  layer-to-layer  alignment, 
pattern placement, surface topography and electro-optical properties are important in many industries as critical dimensions 
narrow, film thicknesses shrink to countable numbers of atomic layers and devices become more complex.  

Our  5D  Patterning  Control  Solution  addresses  five  elements  of  patterning  process  control--the  three  geometrical 
dimensions  of  device  structures,  time-to-results  and  overall  equipment  efficiency--and  supports  advanced  patterning 
technologies through the characterization, optimization and monitoring of fab-wide processes. In February 2017, we launched 
several metrology products that are key components in our 5D Patterning Control Solution and help accelerate the ramp of 
innovative patterning techniques for advanced design node devices: 

Overlay Metrology 

To  help  achieve  sub-3nm  overlay  error  for  advanced  logic  and  memory  devices  we  introduced  the  Archer  600 
imaging-based overlay metrology system. New optics in combination with innovative ProAIM targets deliver better 
resilience to process variations and improved correlation between measurement target and actual device pattern overlay 
errors, producing more accurate overlay measurements.  

Patterned Wafer Geometry Metrology 

The WaferSight PWG2 system was introduced to measure comprehensive wafer stress and shape uniformity data 
with  significant  productivity  improvements.  The  WaferSight  PWG2  system  enables  faster  process  ramp,  overlay 
control, lithography focus window control and in-line process monitoring for processes such as thin films, etch, CMP 
and rapid thermal processing (“RTP”). 

Optical CD and Shape Metrology 

The SpectraShape 10K optical-based metrology system was introduced to measure the CDs and three-dimensional 
shapes of complex IC device structures following etch, chemical mechanical planarization (CMP) and other process 
steps.  Several  new  optical  technologies  including  a  new  high  brightness  light  source  illumination  enable  accurate 
measurements of critical parameters in FinFET and 3D NAND devices.  

The  products  that  we  launched  during  the  fiscal  year  ended  June  30,  2017  further  strengthened  our  broad  range  of 
offerings that support the metrology market. The Archer Series of overlay metrology tools enables characterization of overlay 
error on lithography process layers for advanced patterning technologies. The SpectraShape family of optical CD and shape 
metrology  systems  characterizes  and  monitors  the  critical  dimensions  and  3D  shapes  of  geometrically  complex  features 
incorporated  by  some  IC  manufacturers  in  their  latest  generation  devices.  The  SpectraFilm  and  Aleris  families  of  film 
metrology tools provide precise measurement of film thickness, refractive index, stress and composition for a broad range of 
film layers. The WaferSight PWG system measures patterned wafer geometry after a wide range of IC processes, helping 
identify and monitor variations that can affect patterning. Finally, 5D Analyzer offers advanced, run-time data analysis for a 
wide range of metrology system types. In addition, we offer a number of other products for the metrology market, as reflected 
in the product table at the conclusion of this “Products” section. 

In-Situ Process Monitoring 

KLA-Tencor’s SensArray sensor wafers are a portfolio of advanced wireless and wired temperature monitoring wafers 
that capture the effect of the process environment on production wafers. These sensor wafers provide insight into thermal 
uniformity  and  profile  temperature  under  real  production  conditions.  In  February  2017  we  introduced  the  SensArray 
HighTemp 4mm wireless wafer, which provides temporal and spatial temperature information for advanced films processes. 
With a thinner wafer profile than its predecessor, the SensArray HighTemp 4mm is compatible with a wider range of process 
tool  types,  including  track,  strip  and  physical  vapor  deposition  (“PVD”)  systems.  SensArray  products  are  used  in  many 
semiconductor and flat panel display fabrication processes, including lithography, etch and deposition. 

5 

 
Lithography Software 

KLA-Tencor’s  PROLITH  product  line  provides  researchers  at  advanced  IC  manufacturers,  lithography  hardware 
suppliers,  track  companies  and  material  providers  with  virtual  lithography  software  to  explore  critical-feature  designs, 
manufacturability and process-limited yield of proposed lithographic technologies without the time and expense of printing 
hundreds  of  test  wafers  using  experimental  materials  and  prototype  process  equipment.  Our  ProDATA  process  window 
analysis software tool provides analysis of experimental data, including CD, roughness, sidewall angle, top loss and pattern 
collapse. 

In  December  2016  we  introduced  PROLITH  X6.0,  which  includes  new  modeling  features  and  productivity 
improvements to support key lithography segments such as EUV, 193nm  immersion, multiple patterning and thick resist 
lithography for 3D interconnects and MEMS manufacturing. 

Wafer Manufacturing 

KLA-Tencor’s portfolio of products focused on the demands of wafer manufacturers includes inspection, metrology 
and data management systems. Specialized inspection tools assess surface quality and detect, count and bin defects during 
the wafer manufacturing process and as a critical part of outgoing inspection. Wafer geometry tools ensure that the wafer is 
extremely flat and uniform in thickness, with precisely controlled surface topography. Specifications for wafer defectivity, 
geometry and surface quality are tightening as the dimensions of transistors become so small that the geometry of the substrate 
can substantially affect transistor performance. 

Our unpatterned wafer inspection portfolio is comprised of the Surfscan SP5, the Surfscan SP5XPand the Surfscan SP3 
Series.  These  unpatterned  wafer  inspection  systems  are  designed  to  enable  development  and  production  monitoring  of 
polished  wafers,  epi  wafers  and  engineered  substrates.  The  integrated  SURFmonitor  module  characterizes  wafer  surface 
quality and captures low-contrast defects. The WaferSight Series offers bare wafer geometry and nanotopography metrology 
capabilities. FabVision offers fab-wide data management and automated yield analysis for wafer manufacturers.  

Reticle Manufacturing 

Error-free reticles, or masks, are necessary to achieving high semiconductor device yields, since reticle defects can be 
replicated in every die on production wafers. KLA-Tencor offers high sensitivity reticle inspection and metrology systems 
for mask shops, designed to help them manufacture reticles that are free of pattern defects that could print on the wafers and 
meet pattern placement and critical dimension uniformity specifications. In August 2016 we launched the Teron 640 and 
RDC systems to support the ability of leading-edge mask shops to accurately qualify advanced optical masks. The Teron 640 
inspection  system  utilizes  193nm  illumination  with  Dual  Imaging  mode  to  provide  the  sensitivity  required  for  high-
performance reticle quality control. RDC is a comprehensive data analysis and storage platform that supports multiple KLA-
Tencor reticle inspection and metrology platforms for mask shops and IC fabs. 

Our reticle inspection portfolio includes the Teron 600 Series for development and manufacturing of advanced optical 
and EUV masks, the TeraScan 500XR system for production of reticles for the 32nm node and above, and our X5.3 and 
Teron SL650 Series products for reticle quality control at IC fabs. These products include the capability for mapping critical 
dimension uniformity across the reticle. In addition, we offer the LMS IPRO line of reticle metrology systems for measuring 
pattern  placement  error,  including  the  LMS  IPRO6,  which  measures  on-device  pattern  features  in  addition  to  standard 
registration marks. If the pattern on the reticle is displaced from its intended location, overlay error can result on the wafer, 
which can lead to electrical continuity issues affecting yield, performance or reliability of the IC device. 

Advanced Packaging 

KLA-Tencor offers standalone and cluster inspection and metrology systems for various applications in the field of 
advanced  semiconductor  packaging  (i.e.,  at  the  middle  and  back-end  of  the  semiconductor  manufacturing  process).  Our 
CIRCL-AP all-surface and 89xx-AP front side wafer inspection, metrology and review systems support advanced wafer-level 
packaging processes, such as 2.5D/3D IC integration using through silicon vias (“TSVs”), wafer-level chip scale packaging 

6 

 
(“WLCSP”) and fan-out wafer-level packaging (“FOWLP”). Used for packaging applications associated with LEDs, MEMS, 
image  sensors  and  flip-chip  packaging,  our  WI-22xx  Series  products  focus  on  front  side  wafer  inspection  and  provide 
feedback on wafer surface quality, quality of the wafer dicing, or quality of wafer bumps, pads, pillars and interconnects. Our 
component inspector products, including the ICOS T830, inspect various semiconductor components that are handled in a 
tray,  such  as  microprocessors  or  memory  chips.  Component  inspection  capability  includes  3D  coplanarity  inspection, 
measurement of the evenness of the contacts, component height and two-dimensional (“2D”) surface inspection. In March 
2017, we introduced the ICOS T3 and T7 Series tools, which provide high performance, fully automated optical inspection 
of packaged integrated circuit (IC) components, with either tray (T3) or tape (T7) output capability. Both incorporate the new 
SPECTRUM and SIGMA modules, which produce increased 2D and 3D measurement sensitivity for improved detection of 
issues  that  affect  final  package  quality.  In  June  2017,  KLA-Tencor  acquired  a  privately-held  company,  whose  products 
include optical  surface profilers  measuring both wafers  and  large panels for  advanced packaging  metrology  applications. 
These applications include under-bump metallization (“UBM”) height and roughness, copper pillar height and roughness, 
and redistribution line (“RDL”) height and width. 

LED, Power Device, Compound Semiconductor and MEMS Manufacturing 

LEDs are becoming more commonly used in solid-state lighting, television and notebook backlighting, and automotive 
applications.  As  LED  device  makers  target  aggressive  cost  and  performance  targets,  they  place  significant  emphasis  on 
improved process control and yield during the manufacturing process. 

KLA-Tencor offers a portfolio of systems to help LED manufacturers reduce production costs and increase product 
output: Candela 8720, WI-2280, 8 Series, MicroXAM Series optical profilers and P-Series and HRP-Series stylus profilers. 
The  Candela  8720  substrate  and  epi  wafer  inspection  system  provides  automated  inspection  and  quality  control  of  LED 
substrates, detecting defects that can impact device performance, yield and field reliability. The WI-2280 system is designed 
specifically  for  defect  inspection  and  2D  metrology  for  LED  applications.  The  8  Series  provides  patterned  wafer  defect 
inspection capability for LED manufacturing. The MicroXAM Series optical profilers measure step height, texture and form 
for LED applications. The P-Series and HRP-Series stylus profilers are metrology systems for measurement of step heights 
and roughness for LED substrates and pattern wafer applications. 

Leading power device manufacturers are targeting faster development and ramp times, high product yields and lower 
device costs. To achieve these goals, they are implementing solutions for characterizing yield-limiting defects and processes. 
Full-surface, high sensitivity defect inspection and profiler metrology systems provide accurate process feedback, enabling 
improvements in SiC substrate quality and optimal epitaxial growth yields on both SiC epi and GaN-on-silicon processes.  

KLA-Tencor offers  inspection  and  metrology  systems  to  support power  device  manufacturing. The Candela  CS920 
inspection  system  integrates  surface  defect  detection  and  photoluminescence  technology  for  inspection  and  defect 
classification of a wide range of defects on SiC substrates and epi layers. The MicroXAM Series optical profilers measure 
step height, texture and form for power device applications. The P-Series and HRP-Series stylus profilers measure step heights 
and roughness for SiC substrates and patterned wafer applications. 

Our primary products for compound semiconductor manufacturing include the Candela CS20 inspection system, the 
MicroXAM Series optical profilers and the P-Series and HRP-Series stylus profilers, used for the inspection and metrology 
of substrates, epi-layers and process films.  

In October 2016, we introduced the P-170 stylus profiler with an integrated wafer handler, providing fully automated 
measurements to support LED, GaAs and power device manufacturers. In addition, the HRP-260 was introduced in July 2016 
as the latest generation of our HRP (High Resolution Profiler) Series focused on providing both high resolution and high-
aspect  ratio  surface  topography  profiling  to  support  power  device,  LED,  compound  semiconductor  and  MEMS 
manufacturing.  In  June  2017,  KLA-Tencor  acquired  a  privately-held  company,  whose  products  include  optical  surface 
profilers serving LED and MEMS applications used to measure the cone height, diameter and pitch of patterned sapphire 
substrates for LEDs and serve broad applications for MEMS.

The  increasing  demand  for  MEMS  technology  is  coming  from  diverse  industries  such  as  automotive,  space  and 
consumer electronics. MEMS have the potential to transform many product categories by bringing together silicon-based 
microelectronics with micromachining technology, making possible the realization of complete systems-on-a-chip. KLA-
Tencor offers tools and techniques for this emerging market, such as defect inspection and review, optical inspection and 
surface  profiling,  which  were  first  developed  for  the  integrated  circuit  industry.  Products  that  we  offer  for  MEMS 
manufacturing are highlighted in the product table at the conclusion of this “Products” section. 

Data Storage Media/Head Manufacturing 

Advancements in data storage are being driven by a wave of innovative consumer electronics with small form factors 
and immense storage capacities, as well as an increasing need for high-volume storage options to back up modern methods 
of remote computing and networking (such as cloud computing). Our process control and yield management solutions are 
designed to enable customers to rapidly understand and resolve complex manufacturing problems, which can help improve 
time to market and product yields. In the front-end and back-end of thin-film head wafer manufacturing, we offer the same 
process  control  equipment  that  we  serve  to  the  semiconductor  industry.  In  addition,  we  offer  an  extensive  range  of  test 
equipment and surface profilers with particular strength in photolithography. In substrate and media manufacturing, we offer 
metrology and defect inspection solutions with KLA-Tencor’s optical surface analyzers. Products that we offer for the data 
storage  media/head  manufacturing  market  manufacturing  are  highlighted  in  the  product  table  at  the  conclusion  of  this 
“Products” section. 

General Purpose/Lab Applications 

A range of industries, including general scientific and materials research and optoelectronics, require measurements of 
surface topography to either control their processes or research new material characteristics. Typical measurement parameters 
that our tools address include flatness, roughness, curvature, peak-to-valley, asperity, waviness, texture, volume, sphericity, 
slope, density, stress, bearing ratio and distance (mainly in the micron to nanometer range). The June 2017 acquisition of a 
privately-held  company  added  general  metrology  optical  surface  profilers  to  KLA-Tencor’s  portfolio.  These  systems  are 
complementary to KLA-Tencor’s original stylus and optical profiler product lines. The profiler and in-situ process monitoring 
products  that  we  offer  for  general  purpose/lab  applications  are  highlighted  in  the  product  table  at  the  conclusion  of  this

Our business depends upon the capital expenditures of semiconductor manufacturers, which in turn is driven by the 
current and anticipated market demand for ICs and products utilizing ICs. We do not consider our business to be seasonal in 
nature, but it has historically been cyclical with respect to the capital equipment procurement practices of semiconductor 
manufacturers, and it is impacted by the investment patterns of such manufacturers in different global markets. Downturns 
in  the  semiconductor  industry  or  slowdowns  in  the  worldwide  economy  as  well  as  customer  consolidation  could  have  a 
material adverse effect on our future business and financial results. 

Sales, Service and Marketing 

Our sales, service and marketing efforts are aimed at building long-term relationships with our customers. We focus on 
providing a single and comprehensive resource for the full breadth of process control and yield management products and 
services.  Our  customers  benefit  from  the  simplified  planning  and  coordination,  as  well  as  the  increased  equipment 
compatibility, which are realized as a result of dealing with a single supplier for multiple products and services. Our revenues 
are derived primarily from product sales, mostly through our direct sales force. 

We  believe  that  the  size  and  location  of  our  field  sales,  service  and  applications  engineering,  and  marketing 
organizations represent a competitive advantage in our served markets. We have direct sales forces in Asia, the United States 
and  Europe.  We  maintain  an  export  compliance  program  that  is  designed  to  meet  the  requirements  of  the  United  States 
Departments of Commerce and State. 

As of June 30, 2017, we employed approximately 2,220 full-time sales and related personnel, service engineers and 
applications engineers. In addition to sales and service offices in the United States, we conduct sales, marketing and services 
out of subsidiaries or branches in other countries, including Belgium, China, Germany, Israel, Japan, Singapore, Korea and 
Taiwan. International revenues accounted for approximately 86%, 82% and 71% of our total revenues in the fiscal years 
ended June 30, 2017, 2016 and 2015, respectively. Additional information regarding our revenues from foreign operations 
for our last three fiscal years can be found in Note 17, “Segment Reporting and Geographic Information” to the consolidated 
financial statements. 

We believe that sales outside the United States will continue to be a significant percentage of our total revenues. Our 
future performance will depend, in part, on our ability to continue to compete successfully in Asia, one of the largest markets 
for our equipment. Our ability to compete in this area is dependent upon the continuation of favorable trading relationships 
between countries in the region and the United States, and our continuing ability to maintain satisfactory relationships with 
leading semiconductor companies in the region.

International sales and operations may be adversely affected by the imposition of governmental controls, restrictions 
on export technology, political instability, trade restrictions, changes in tariffs and the difficulties associated with staffing and 
managing international operations. In addition, international sales may be adversely affected by the economic conditions in 
each  country  and  by  fluctuations  in  currency  exchange  rates,  and  such  fluctuations  may  negatively  impact  our  ability  to 
compete on price with local providers or the value of revenues we generate from our international business. Although we 
attempt to manage some of the currency risk inherent in non-U.S. dollar product sales through hedging activities, there can 
be  no  assurance  that  such  efforts  will  be  adequate.  These  factors,  as  well  as  any  of  the  other  risk  factors  related  to  our 
international business and operations that are described in Item 1A, “Risk Factors,” could have a material adverse effect on 
our future business and financial results. 

Backlog 

Our shipment backlog for systems and associated warranty totaled $1.46 billion and $1.21 billion as of June 30, 2017 
and 2016, respectively, and primarily consists of sales orders where written customer requests have been received and the 
delivery is anticipated within the next 12 months. Orders for service contracts and unreleased products are excluded from 
shipment backlog. All orders are subject to cancellation or delay by the customer, often with limited or no penalties. We make 
adjustments  for  shipment  backlog  obtained  from  acquired  companies,  sales  order  cancellations,  customer  delivery  date 
changes and currency adjustments. Shipment backlog is not subject to normal accounting controls for information that is 
either reported in or derived from our consolidated financial statements. In addition, the concept of shipment backlog is not 
defined in the accounting literature, making comparisons between periods and with other companies difficult and potentially 
misleading. 

Our revenue backlog, which includes the gross value of sales orders where physical deliveries have been completed, 
but for which revenue has not been recognized pursuant to our policy for revenue recognition, totaled $328.0 million and 
$255.0 million as of June 30, 2017 and 2016, respectively. Orders for service contracts are excluded from revenue backlog. 

Because customers can potentially change delivery schedules or delay or cancel orders, and because some orders are 
received and shipped within the same quarter, our shipment backlog at any particular date is not necessarily indicative of 
business  volumes  or  actual  sales  for  any  succeeding  periods.  The  historical  cyclicality  of  the  semiconductor  industry 
combined with the lead times from our suppliers sometimes result in timing disparities between, on the one hand, our ability 
to manufacture, deliver and install products and, on the other, the requirements of our customers. In our efforts to balance the 
requirements of our customers with the availability of resources, management of our operating model and other factors, we 
often must exercise discretion and judgment as to the timing and prioritization of manufacturing, deliveries and installations 
of products, which may impact the timing of revenue recognition with respect to such products. 

Research and Development 

The market for yield management and process monitoring systems is characterized by rapid technological development 
and  product  innovation.  These  technical  innovations  are  inherently  complex  and  require  long  development  cycles  and 
appropriate professional staffing. We believe that continued and timely development of new products and enhancements to 
existing products are necessary to maintain our competitive position. Accordingly, we devote a significant portion of our 
human and financial resources to research and development programs and seek to maintain close relationships with customers 
to remain responsive to their needs. In addition, we may enter into certain strategic development and engineering programs 
whereby  certain  government  agencies  or  other  third  parties  fund  a  portion  of  our  research  and  development  costs.  As  of 
June 30, 2017, we employed approximately 1,560 full-time research and development personnel. 

Our key research and development activities during the fiscal year ended June 30, 2017 involved the development of 
process control and yield management equipment aimed at addressing the challenges posed by shrinking device sizes, the 
transition to new production materials, new device and circuit architecture, more demanding lithography processes and new 
back-end packaging techniques. For information regarding our research and development expenses during the last three fiscal 
years, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual 
Report on Form 10-K.

The strength of our competitive positions in many of our existing markets is largely due to our leading technology, 
which is the result of our continuing significant investments in product research and development. Even during down cycles 
in  the  semiconductor  industry,  we  have  remained  committed  to  significant  engineering  efforts  toward  both  product 
improvement  and  new  product  development  in  order  to  enhance  our  competitive  position.  New  product  introductions, 
however, may contribute to fluctuations in operating results, since customers may defer ordering existing products, and, if 
new products have reliability or quality problems, those problems may result in reduced orders, higher manufacturing costs, 
delays  in  acceptance  of  and  payment  for  new  products,  and  additional  service  and  warranty  expenses.  There  can  be  no 
assurance that we will successfully develop and manufacture new products, or that new products introduced by us will be 
accepted in the marketplace. If we do not successfully introduce new products, our results of operations will be adversely 
affected. 

Manufacturing, Raw Materials and Supplies 

We perform system design, assembly and testing in-house and utilize an outsourcing strategy for the manufacture of 
components  and  major  subassemblies.  Our  in-house  manufacturing  activities  consist  primarily  of  assembling  and  testing 
components and subassemblies that are acquired through third-party vendors and integrating those subassemblies into our 
finished products. Our principal manufacturing activities take place in the United States (Milpitas, California), Singapore, 
Israel, Germany and China. As of June 30, 2017, we employed approximately 1090 full-time manufacturing personnel. 

Some  critical  parts,  components  and  subassemblies  (collectively,  “parts”)  that  we  use  are  designed  by  us  and 
manufactured by suppliers in accordance with our specifications, while other parts are standard commercial products. We use 
numerous vendors to supply parts and raw materials for the manufacture and support of our products. Although we make 
reasonable efforts to ensure that these parts and raw materials are available from multiple suppliers, this is not always possible, 
and certain parts and raw materials included in our systems may be obtained only from a single supplier or a limited group 
of suppliers. Through our business interruption planning, we endeavor to minimize the risk of production interruption by, 
among  other  things,  monitoring  the  financial  condition  of  suppliers  of  key  parts  and  raw  materials,  identifying  (but  not 
necessarily qualifying) possible alternative suppliers of such parts and materials, and ensuring adequate inventories of key 
parts and raw materials are available to maintain manufacturing schedules. 

Although we seek to reduce our dependence on sole and limited source suppliers, in some cases the partial or complete 
loss of certain of these sources, or disruptions within our suppliers’ often-complex supply chains, could disrupt scheduled 
deliveries to customers, damage customer relationships and have a material adverse effect on our results of operations. 

Competition 

The worldwide market for process control and yield management systems is highly competitive. In each of our product 
markets, we face competition from established and potential competitors, such as Applied Materials, Inc., ASML Holding 
N.V., Hitachi High-Technologies Corporation, Nanometrics, Inc. and Rudolph Technologies, Inc., some of which may have 
greater  financial,  research,  engineering,  manufacturing  and  marketing  resources  than  we  have.  We  may  also  face  future 
competition from new market entrants from other overseas and domestic sources. We expect our competitors to continue to 
improve the design and performance of their current products and processes and to introduce new products and processes 
with  improved  price  and performance  characteristics. We believe  that,  to  remain  competitive,  we will  require significant 
financial resources to offer a broad range of products, to maintain customer service and support centers worldwide, and to 
invest in product and process research and development. 

We believe that, while price and delivery are important competitive factors, the customers’ overriding requirement is 
for systems that easily and effectively incorporate automated and highly accurate inspection and metrology capabilities into 
their  existing  manufacturing  processes  to  enhance  productivity.  Significant  competitive  factors  in  the  market  for  process 
control and yield management systems include system performance, ease of use, reliability, interoperability with the existing 
installed base and technical service and support, as well as overall cost of ownership. 

13 

 
Management believes that we are well positioned in the market with respect to both our products and services. However, 
any loss of competitive position could negatively impact our prices, customer orders, revenues, gross margins and market 
share, any of which would negatively impact our operating results and financial condition. 

Acquisitions and Alliances 

We  continuously  evaluate  strategic  acquisitions  and  alliances  to  expand  our  technologies,  product  offerings  and 
distribution capabilities. Acquisitions involve numerous risks, including management issues and costs in connection with 
integration of the operations, technologies and products of the acquired companies, and the potential loss of key employees 
of the acquired companies. The inability to manage these risks effectively could negatively impact our operating results and 
financial condition. 

Patents and Other Proprietary Rights 

We protect our proprietary technology through reliance on a variety of intellectual property laws, including patent, 
copyright and trade secret. We have filed and obtained a number of patents in the United States and abroad and intend to 
continue pursuing the legal protection of our technology through intellectual property laws. In addition, from time to time we 
acquire license rights under United States and foreign patents and other proprietary rights of third parties, and we attempt to 
protect our trade secrets and other proprietary information through confidentiality and other agreements with our customers, 
suppliers, employees and consultants and through other security measures. 

Although  we  consider  patents  and  other  intellectual  property  significant  to  our  business,  due  to  the  rapid  pace  of 
innovation within the process control and yield management systems industry, we believe that our protection through patent 
and  other  intellectual  property  rights  is  less  important  than  factors  such  as  our  technological  expertise,  continuing 
development of new systems, market penetration, installed base and the ability to provide comprehensive support and service 
to customers worldwide. 

No assurance can be given that patents will be issued on any of our applications, that license assignments will be made 
as anticipated, or that our patents, licenses or other proprietary rights will be sufficiently broad to protect our technology. No 
assurance can be given that any patents issued to or licensed by us will not be challenged, invalidated or circumvented or that 
the rights granted thereunder will provide us with a competitive advantage. In addition, there can be no assurance that we 
will be able to protect our technology or that competitors will not be able to independently develop similar or functionally 
competitive technology. 

Environmental Matters 

We are subject to a variety of federal, state and local governmental laws and regulations related to the protection of the 
environment, including without limitation the management of hazardous materials that we use in our business operations. 
Compliance with these environmental laws and regulations has not had, and is not expected to have, a material effect on our 
capital expenditures, financial condition, results of operations or competitive position.  

However, any failure to comply with environmental laws and regulations may subject us to a range of consequences, 
including fines, suspension of certain of our business activities, limitations on our ability to sell our products, obligations to 
remediate  environmental  contamination,  and  criminal  and  civil  liabilities  or  other  sanctions.  In  addition,  changes  in 
environmental  laws  and regulations could  require us  to  invest  in potentially  costly  pollution  control  equipment,  alter our 
manufacturing processes or use substitute materials. Our failure to comply with these laws and regulations could subject us 
to future liabilities. 

Employees 

As of June 30, 2017, we employed approximately 5,990 full-time employees. Except for our employees in Belgium 
(where a trade union delegation has been recognized) and our employees in the German operations of our MIE business unit 
(who are represented by employee works council), none of our employees are represented by a labor union. We have not 
experienced work stoppages and believe that our employee relations are good.  

14 

 
Competition is intense in the recruiting of personnel in the semiconductor and semiconductor equipment industry. We 
believe  that  our  future  success  will  depend,  in  part,  on  our  continued  ability  to  hire  and  retain  qualified  management, 
marketing and technical employees.

RISK FACTORS 

A description of factors that could materially affect our business, financial condition or operating results is provided 

below. 

Risks Associated with Our Industry  

Ongoing changes in the technology industry, as well as the semiconductor industry in particular, could expose our 

business to significant risks.  

The semiconductor equipment industry and other industries that we serve are constantly developing and changing over 
time. Many of the risks associated with operating in these industries are comparable to the risks faced by all technology 
companies, such as the uncertainty of future growth rates in the industries that we serve, pricing trends in the end-markets for 
consumer electronics and other products (which place a growing emphasis on our customers’ cost of ownership), changes in 
our customers’ capital spending patterns and, in general, an environment of constant change and development, including 
decreasing  product  and  component  dimensions;  use  of  new  materials;  and  increasingly  complex  device  structures, 
applications and process steps. If we fail to appropriately adjust our cost structure and operations to adapt to any of these 
trends, or, with respect to technological advances, if we do not timely develop new technologies and products that successfully 
anticipate and address these changes, we could experience a material adverse effect on our business, financial condition and 
operating results. 

In addition, we face a number of risks specific to ongoing changes in the semiconductor industry, as the significant 
majority  of  our  sales  are  made  to  semiconductor  manufacturers.  Some  of  the  trends  that  our  management  monitors  in 
operating our business include the following: 

• 

• 

• 

• 

• 

• 

• 

• 

the potential for reversal of the long-term historical trend of declining cost per transistor with each new generation
of technological advancement within the semiconductor industry, and the adverse impact that such reversal may 
have upon our business; 

the increasing cost of building and operating fabrication facilities and the impact of such increases on our customers’
investment decisions;  

differing market growth rates and capital requirements for different applications, such as memory, logic and foundry;

lower level of process control adoption by our memory customers compared to our foundry and logic customers;

our customers’ reuse of existing and installed products, which may decrease their need to purchase new products or
solutions at more advanced technology nodes; 

the emergence of disruptive technologies that change the prevailing semiconductor manufacturing processes (or the
economics associated with semiconductor manufacturing) and, as a result, also impact the inspection and metrology
requirements associated with such processes;  

the higher design costs for the most advanced integrated circuits, which could economically constrain leading-edge 
manufacturing technology customers to focus their resources on only the large, technologically advanced products
and applications; 

the  possible  introduction  of  integrated  products  by  our  larger  competitors  that  offer  inspection  and  metrology
functionality in addition to managing other semiconductor manufacturing processes; 

17 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

• 

• 

changes in semiconductor manufacturing processes that are extremely costly for our customers to implement and,
accordingly,  our  customers  could  reduce  their  available  budgets  for  process  control  equipment  by  reducing
inspection and metrology sampling rates for certain technologies; 

the bifurcation of the semiconductor manufacturing industry into (a) leading edge manufacturers driving continued
research  and  development  into  next-generation  products  and  technologies  and  (b)  other  manufacturers  that  are 
content with existing (including previous generation) products and technologies; 

the ever escalating cost of next-generation product development, which may result in joint development programs
between us and our customers or government entities to help fund such programs that could restrict our control of,
ownership of and profitability from the products and technologies developed through those programs; and 

the entry by some semiconductor manufacturers into collaboration or sharing arrangements for capacity, cost or risk 
with other manufacturers, as well as increased outsourcing of their manufacturing activities, and greater focus only
on specific markets or applications, whether in response to adverse market conditions or other market pressures.  

Any of the changes described above may negatively affect our customers’ rate of investment in the capital equipment 
that we produce, which could result in downward pressure on our prices, customer orders, revenues and gross margins. If we 
do not successfully manage the risks resulting from any of these or other potential changes in our industries, our business, 
financial condition and operating results could be adversely impacted. 

We are exposed to risks associated with a highly concentrated customer base. 

Our customer base, particularly in the semiconductor industry, historically has been, and is becoming increasingly, 
highly concentrated due to corporate consolidation, acquisitions and business closures. In this environment, orders from a 
relatively limited number of manufacturers have accounted for, and are expected to continue to account for, a substantial 
portion of our sales. This increasing concentration exposes our business, financial condition and operating results to a number 
of risks, including the following:  

• 

The mix and type of customers, and sales to any single customer, may vary significantly from quarter to quarter and
from  year  to  year,  which  exposes  our  business  and  operating  results  to  increased  volatility  tied  to  individual
customers.  

•  New orders from our foundry customers in the past several years have constituted a significant portion of our total
orders.  This  concentration  increases  the  impact  that  future  business  or  technology  changes  within  the  foundry
industry may have on our business, financial condition and operating results.  

• 

In a highly concentrated business environment, if a particular customer does not place an order, or if they delay or
cancel orders, we may not be able to replace the business. Furthermore, because our products are configured to each
customer’s specifications, any changes, delays or cancellations of orders may result in significant, non-recoverable 
costs.  

•  As a result of this consolidation, the customers that survive the consolidation represent a greater portion of our sales
and, consequently, have greater commercial negotiating leverage. Many of our large customers have more aggressive
policies regarding engaging alternative, second-source suppliers for the products we offer and, in addition, may seek
and, on occasion, receive pricing, payment, intellectual property-related or other commercial terms that may have
an  adverse  impact  on  our  business.  Any  of  these  changes  could  negatively  impact  our  prices,  customer  orders,
revenues and gross margins.  

• 

Certain  customers  have  undergone  significant  ownership  changes,  created  alliances  with  other  companies,
experienced management changes or have outsourced manufacturing activities, any of which may result in additional

18 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

• 

complexities in managing customer relationships and transactions. Any future change in ownership or management
of our existing customers may result in similar challenges, including the possibility of the successor entity or new
management deciding to select a competitor’s products. 

The highly concentrated business environment also increases our exposure to risks related to the financial condition
of each of our customers. For example, as a result of the challenging economic environment during fiscal year 2009,
we were (and in some cases continue to be) exposed to additional risks related to the continued financial viability of
certain of our customers. To the extent our customers experience liquidity issues in the future, we may be required
to  incur  additional  bad  debt  expense  with  respect  to  receivables  owed  to  us  by  those  customers.  In  addition,
customers with liquidity issues may be forced to reduce purchases of our equipment, delay deliveries of our products,
discontinue operations or may be acquired by one of our customers, and in either case such event would have the
effect of further consolidating our customer base.  

Semiconductor manufacturers generally must commit significant resources to qualify, install and integrate process
control  and  yield  management  equipment  into  a  semiconductor  production  line.  We  believe  that  once  a
semiconductor manufacturer selects a particular supplier’s process control and yield management equipment, the
manufacturer generally relies upon that equipment for that specific production line application for an extended period 
of time. Accordingly, we expect it to be more difficult to sell our products to a given customer for that specific
production  line  application  and  other  similar  production  line  applications  if  that  customer  initially  selects  a
competitor’s equipment. Similarly, we expect it to be challenging for a competitor to sell its products to a given
customer for a specific production line application if that customer initially selects our equipment. 

Prices  differ  among  the  products  we  offer  for  different  applications  due  to  differences  in  features  offered  or
manufacturing costs. If there is a shift in demand by our customers from our higher-priced to lower-priced products, 
our gross margin and revenue would decrease. In addition, when products are initially introduced, they tend to have
higher costs because of initial development costs and lower production volumes relative to the previous product
generation, which can impact gross margin. 

Any of these factors could have a material adverse effect on our business, financial condition and operating results. 

The semiconductor equipment industry has been cyclical. The purchasing decisions of our customers are highly 
dependent on the economies of both the local markets in which they are located and the semiconductor industry worldwide. 
If we fail to respond to industry cycles, our business could be seriously harmed. 

The timing, length and severity of the up-and-down cycles in the semiconductor equipment industry are difficult to 
predict. The historically cyclical nature of the primary industry in which we operate is largely a function of our customers’ 
capital spending patterns and need for expanded manufacturing capacity, which in turn are affected by factors such as capacity 
utilization,  consumer  demand  for  products,  inventory  levels  and  our  customers’  access  to  capital.  Cyclicality  affects  our 
ability to accurately predict future revenue and, in some cases, future expense levels. During down cycles in our industry, the 
financial results of our customers may be negatively impacted, which could result not only in a decrease in, or cancellation 
or delay of, orders (which are generally subject to cancellation or delay by the customer with limited or no penalty) but also 
a weakening of their financial condition that could impair their ability to pay for our products or our ability to recognize 
revenue from certain customers. Our ability to recognize revenue from a particular customer may also be negatively impacted 
by the customer’s funding status, which could be weakened not only by adverse business conditions or inaccessibility to 
capital markets for any number of macroeconomic or company-specific reasons, but also by funding limitations imposed by 
the customer’s unique corporate structure. Any of these factors could negatively impact our business, operating results and 
financial condition.  

When cyclical fluctuations result in lower than expected revenue levels, operating results may be adversely affected 
and cost reduction measures may be necessary in order for us to remain competitive and financially sound. During periods of 
declining revenues, we must be in a position to adjust our cost and expense structure to prevailing market conditions and to 

19 

 
 
 
 
 
 
 
continue to motivate and retain our key employees. If we fail to respond, or if our attempts to respond fail to accomplish our 
intended results, then our business could be seriously harmed. Furthermore, any workforce reductions and cost reduction 
actions that we adopt in response to down cycles may result in additional restructuring charges, disruptions in our operations 
and loss of key personnel. In addition, during periods of rapid growth, we must be able to increase manufacturing capacity 
and personnel to meet customer demand. We can provide no assurance that these objectives can be met in a timely manner 
in response to industry cycles. Each of these factors could adversely impact our operating results and financial condition. 

In addition, our management typically provides quarterly forecasts for certain financial metrics, which, when made, are 
based  on  business  and  operational  forecasts  that  are  believed  to  be  reasonable  at  the  time.  However,  largely  due  to  the 
historical  cyclicality  of  our  business  and  the  industries  in  which  we  operate,  and  the  fact  that  business  conditions  in  our 
industries can change very rapidly as part of these cycles, our actual results may vary (and have varied in the past) from 
forecasted results. These variations can occur for any number of reasons, including, but not limited to, unexpected changes 
in the volume or timing of customer orders, product shipments or product acceptances; an inability to adjust our operations 
rapidly enough to adapt to changing business conditions; or a different than anticipated effective tax rate. The impact on our 
business of delays or cancellations of customer orders may be exacerbated by the short lead times that our customers expect 
between order placement and product shipment. This is because order delays and cancellations may lead not only to lower 
revenues, but also, due to the advance work we must do in anticipation of receiving a product order to meet the expected lead 
times, to significant inventory write-offs and manufacturing inefficiencies that decrease our gross margin. Any of these factors 
could  materially  and  adversely  affect  our  financial  results  for  a  particular  quarter  and  could  cause  those  results  to  differ 
materially from financial forecasts we have previously provided. We provide these forecasts with the intent of giving investors 
and analysts a better understanding of management’s expectations for the future, but those reviewing such forecasts must 
recognize  that  such  forecasts  are  comprised  of,  and  are  themselves,  forward-looking  statements  subject  to  the  risks  and 
uncertainties described in this Item 1A and elsewhere in this report and in our other public filings and public statements. If 
our operating or financial results for a particular period differ from our forecasts or the expectations of investment analysts, 
or if we revise our forecasts, the market price of our common stock could decline. 

Risks Related to Our Business Model and Capital Structure 

If  we  do  not  develop  and  introduce  new  products  and  technologies  in  a  timely  manner  in  response  to  changing 

market conditions or customer requirements, our business could be seriously harmed. 

Success in the semiconductor equipment industry depends, in part, on continual improvement of existing technologies 
and rapid innovation of new solutions. The primary driver of technology advancement in the semiconductor industry has 
been to shrink the lithography that prints the circuit design on semiconductor chips. That driver appears to be slowing, which 
may cause semiconductor manufacturers to delay investments in equipment, investigate more complex device architectures, 
use new materials and develop innovative fabrication processes. These and other evolving customer plans and needs require 
us to respond with continued development programs and cut back or discontinue older programs, which may no longer have 
industry-wide support. Technical innovations are inherently complex and require long development cycles and appropriate 
staffing  of  highly  qualified  employees.  Our  competitive  advantage  and  future  business  success  depend  on  our  ability  to 
accurately predict evolving industry standards, develop and introduce new products and solutions that successfully address 
changing customer needs, win market acceptance of these new products and solutions, and manufacture these new products 
in a timely and cost-effective manner. Our failure to accurately predict evolving industry standards and develop as well as 
offer competitive technology solutions in a timely manner with cost-effective products could result in loss of market share, 
unanticipated costs, and inventory obsolescence, which would adversely impact our business, operating results and financial 
condition. 

We must continue to make significant investments in research and development in order to enhance the performance, 
features  and  functionality  of  our  products,  to  keep  pace  with  competitive  products  and  to  satisfy  customer  demands. 
Substantial research and development costs typically are incurred before we confirm the technical feasibility and commercial 
viability  of  a  new  product,  and  not  all  development  activities  result  in  commercially  viable  products.  There  can  be  no 
assurance that revenues from future products or product enhancements will be sufficient to recover the development costs 

20 

 
associated with such products or enhancements. In addition, we cannot be sure that these products or enhancements will 
receive market acceptance or that we will be able to sell these products at prices that are favorable to us. Our business will 
be seriously harmed if we are unable to sell our products at favorable prices or if the market in which we operate does not 
accept our products. 

In addition, the complexity of our products exposes us to other risks. We regularly recognize revenue from a sale upon 
shipment of the applicable product to the customer (even before receiving the customer’s formal acceptance of that product) 
in certain situations, including sales of products for which installation is considered perfunctory, transactions in which the 
product is sold to an independent distributor and we have no installation obligations, and sales of products where we have 
previously delivered the same product to the same customer location and that prior delivery has been accepted. However, our 
products are very technologically complex and rely on the interconnection of numerous subcomponents (all of which must 
perform to their respective specifications), so it is conceivable that a product for which we recognize revenue upon shipment 
may ultimately fail to meet the overall product’s required specifications. In such a situation, the customer may be entitled to 
certain remedies, which could materially and adversely affect our operating results for various periods and, as a result, our 
stock price. 

We derive a substantial percentage of our revenues from sales of inspection products. As a result, any delay or reduction 
of sales of these products could have a material adverse effect on our business, financial condition and operating results. The 
continued customer demand for these products and the development, introduction and market acceptance of new products 
and technologies are critical to our future success. 

Our success is dependent in part on our technology and other proprietary rights. If we are unable to maintain our 

lead or protect our proprietary technology, we may lose valuable assets. 

Our success is dependent in part on our technology and other proprietary rights. We own various United States and 
international patents and have additional pending patent applications relating to some of our products and technologies. The 
process of seeking patent protection is lengthy and expensive, and we cannot be certain that pending or future applications 
will  actually  result  in  issued  patents  or  that  issued  patents  will  be  of  sufficient  scope  or  strength  to  provide  meaningful 
protection or commercial advantage to us. Other companies and individuals, including our larger competitors, may develop 
technologies and obtain patents relating to our business that are similar or superior to our technology or may design around 
the patents we own, adversely affecting our business. In addition, we at times engage in collaborative technology development 
efforts with our customers and suppliers, and these collaborations may constitute a key component of certain of our ongoing 
technology and product research and development projects. The termination of any such collaboration, or delays caused by 
disputes or other unanticipated challenges that may arise in connection with any such collaboration, could significantly impair 
our research and development efforts, which could have a material adverse impact on our business and operations. 

We  also  maintain  trademarks  on  certain  of  our  products  and  services  and  claim  copyright  protection  for  certain 
proprietary  software  and  documentation.  However, we  can give no  assurance  that our trademarks  and  copyrights will  be 
upheld or successfully deter infringement by third parties. 

While patent, copyright and trademark protection for our intellectual property is important, we believe our future success 
in highly dynamic markets is most dependent upon the technical competence and creative skills of our personnel. We attempt 
to protect our trade secrets and other proprietary information through confidentiality and other agreements with our customers, 
suppliers, employees and consultants and through other security measures. We also maintain exclusive and non-exclusive 
licenses with third parties for strategic technology used in certain products. However, these employees, consultants and third 
parties may breach these agreements, and we may not have adequate remedies for wrongdoing. In addition, the laws of certain 
territories in which we develop, manufacture or sell our products may not protect our intellectual property rights to the same 
extent as do the laws of the United States. In any event, the extent to which we can protect our trade secrets through the use 
of confidentiality agreements is limited, and our success will depend to a significant extent on our ability to innovate ahead 
of our competitors. 

21 

 
 
 
Our future performance depends, in part, upon our ability to continue to compete successfully worldwide. 

Our industry includes large manufacturers with substantial resources to support customers worldwide. Some of our 
competitors  are  diversified  companies  with  greater  financial  resources  and  more  extensive  research,  engineering, 
manufacturing,  marketing,  and  customer  service  and  support  capabilities  than  we  possess.  We  face  competition  from 
companies whose strategy is to provide a broad array of products and services, some of which compete with the products and 
services  that  we  offer.  These  competitors  may  bundle  their  products  in  a  manner  that  may  discourage  customers  from 
purchasing our products, including pricing such competitive tools significantly below our product offerings. In addition, we 
face competition from smaller emerging semiconductor equipment companies whose strategy is to provide a portion of the 
products and services that we offer, using innovative technology to sell products into specialized markets. The strength of 
our competitive positions in many of our existing markets is largely due to our leading technology, which is the result of 
continuing  significant  investments  in  product  research  and  development.  However,  we  may  enter  new  markets,  whether 
through acquisitions or new internal product development, in which competition is based primarily on product pricing, not 
technological  superiority.  Further,  some  new  growth  markets  that  emerge  may  not  require  leading  technologies.  Loss  of 
competitive position in any of the markets we serve, or an inability to sell our products on favorable commercial terms in 
new markets we may enter, could negatively affect our prices, customer orders, revenues, gross margins and market share, 
any of which would negatively affect our operating results and financial condition. 

Our  business  would  be  harmed  if  we  do  not  receive  parts  sufficient  in  number  and  performance  to  meet  our 

production requirements and product specifications in a timely and cost-effective manner. 

We  use  a  wide  range  of  materials  in  the  production  of  our  products,  including  custom  electronic  and  mechanical 
components,  and  we  use  numerous  suppliers  to  supply  these  materials.  We  generally  do  not  have  guaranteed  supply 
arrangements  with  our  suppliers.  Because  of  the  variability  and uniqueness  of  customers’  orders,  we  do  not  maintain  an 
extensive inventory of materials for manufacturing. Through our business interruption planning, we seek to minimize the risk 
of production and service interruptions and/or shortages of key parts by, among other things, monitoring the financial stability 
of  key  suppliers,  identifying  (but  not  necessarily  qualifying)  possible  alternative  suppliers  and  maintaining  appropriate 
inventories of key  parts.  Although we  make  reasonable  efforts  to  ensure that  parts  are available  from  multiple  suppliers, 
certain key parts are available only from a single supplier or a limited group of suppliers. Also, key parts we obtain from 
some of our suppliers incorporate the suppliers’ proprietary intellectual property; in those cases we are increasingly reliant 
on third parties for high-performance, high-technology components, which reduces the amount of control we have over the 
availability and protection of the technology and intellectual property that is used in our products. In addition, if certain of 
our  key  suppliers  experience  liquidity  issues  and  are  forced  to  discontinue  operations,  which  is  a  heightened  risk  during 
economic  downturns,  it  could  affect  their  ability  to  deliver  parts  and  could  result  in  delays  for  our  products.  Similarly, 
especially  with  respect  to  suppliers  of  high-technology  components, our  suppliers  themselves  have  increasingly  complex 
supply chains, and delays or disruptions at any stage of their supply chains may prevent us from obtaining parts in a timely 
manner and result in delays for our products. Our operating results and business may be adversely impacted if we are unable 
to obtain parts to meet our production requirements and product specifications, or if we are only able to do so on unfavorable 
terms.  Furthermore,  a  supplier  may  discontinue  production  of  a  particular  part  for  any  number  of  reasons,  including  the 
supplier’s financial condition or business operational decisions, which would require us to purchase, in a single transaction, 
a large number of such discontinued parts in order to ensure that a continuous supply of such parts remains available to our 
customers.  Such  “end-of-life”  parts  purchases  could  result  in  significant  expenditures  by  us  in  a  particular  period,  and 
ultimately any unused parts may result in a significant inventory write-off, either of which could have an adverse impact on 
our financial condition and results of operations for the applicable periods. 

22 

 
 
 
If we fail to operate our business in accordance with our business plan, our operating results, business and stock 

price may be significantly and adversely impacted. 

We attempt to operate our business in accordance with a business plan that is established annually, revised frequently 
(generally quarterly), and reviewed by management even more frequently (at least monthly). Our business plan is developed 
based on a number of factors, many of which require estimates and assumptions, such as our expectations of the economic 
environment, future business levels, our customers’ willingness and ability to place orders, lead-times, and future revenue 
and cash flow. Our budgeted operating expenses, for example, are based in part on our future revenue expectations. However, 
our ability to achieve our anticipated revenue levels is a function of numerous factors, including the volatile and historically 
cyclical nature of our primary industry, customer order cancellations, macroeconomic changes, operational matters regarding 
particular  agreements,  our  ability  to  manage  customer  deliveries,  the  availability  of  resources  for  the  installation  of  our 
products, delays or accelerations by customers in taking deliveries and the acceptance of our products (for products where 
customer acceptance is required before we can recognize revenue from such sales), our ability to operate our business and 
sales processes effectively, and a number of the other risk factors set forth in this Item 1A. 

Because our expenses are in most cases relatively fixed in the short term, any revenue shortfall below expectations 
could have an immediate and significant adverse effect on our operating results. Similarly, if we fail to manage our expenses 
effectively or otherwise fail to maintain rigorous cost controls, we could experience greater than anticipated expenses during 
an operating period, which would also negatively affect our results of operations. If we fail to operate our business consistent 
with our business plan, our operating results in any period may be significantly and adversely impacted. Such an outcome 
could cause customers, suppliers or investors to view us as less stable, or could cause us to fail to meet financial analysts’ 
revenue or earnings estimates, any of which could have an adverse impact on our stock price. 

In addition, our management is constantly striving to balance the requirements and demands of our customers with the 
availability of resources, the need to manage our operating model and other factors. In furtherance of those efforts, we often 
must  exercise  discretion  and  judgment  as  to  the  timing  and  prioritization  of  manufacturing,  deliveries,  installations  and 
payment  scheduling. Any  such decisions  may  impact  our ability  to  recognize revenue,  including  the fiscal  period during 
which such revenue may be recognized, with respect to such products, which could have a material adverse effect on our 
business, results of operations or stock price. 

Our capital structure is highly leveraged. 

As of June 30, 2017, we had $2.95 billion aggregate principal amount of outstanding indebtedness, consisting of $2.50 
billion aggregate principal amount of senior, unsecured long-term notes and $446.3 million of term loans under a Credit 
Agreement  (the  “Credit  Agreement”).  Additionally,  we  have  commitments  for  an  unfunded  revolving  credit  facility  of 
$500.0 million under the Credit Agreement. We may incur additional indebtedness in the future by accessing the unfunded 
revolving credit facility under the Credit Agreement and/or entering into new financing arrangements. Our ability to pay 
interest and repay the principal of our current indebtedness is dependent upon our ability to manage our business operations, 
our credit rating, the ongoing interest rate environment and the other risk factors discussed in this section. There can be no 
assurance that we will be able to manage any of these risks successfully. 

In addition, the interest rates of the senior, unsecured long-term notes may be subject to adjustments from time to time 
if  Moody’s  Investors  Service,  Inc.  (“Moody’s”),  Standard  &  Poor’s  Ratings  Services  (“S&P”)  or,  under  certain 
circumstances,  a  substitute  rating  agency  selected  by  us  as  a  replacement  for  Moody’s  or  S&P,  as  the  case  may  be  (a 
“Substitute Rating Agency”), downgrades (or subsequently upgrades) its rating assigned to the respective series of notes such 
that the adjusted rating is below investment grade. Accordingly, changes by Moody’s, S&P, or a Substitute Rating Agency 
to  the  rating  of  any  series  of  notes,  our  outlook  or  credit  rating  could  require  us  to  pay  additional  interest,  which  may 
negatively affect the value and liquidity of our debt and the market price of our common stock could decline. Factors that can 
affect  our  credit  rating  include  changes  in  our  operating  performance,  the  economic  environment,  conditions  in  the 
semiconductor  and  semiconductor  equipment  industries,  our  financial  position,  including  the  incurrence  of  additional 
indebtedness, and our business strategy. 

23 

 
In certain circumstances involving a change of control followed by a downgrade of the rating of a series of notes by at 
least two of Moody’s, S&P and Fitch Inc., unless we have exercised our right to redeem the notes of such series, we will be 
required to make an offer to repurchase all or, at the holder’s option, any part, of each holder’s notes of that series pursuant 
to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, we will be required to offer 
payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if 
any, on the notes repurchased, up to, but not including, the date of repurchase. We cannot make any assurance that we will 
have sufficient financial resources at such time or will be able to arrange financing to pay the repurchase price of that series 
of notes. Our ability to repurchase that series of notes in such event may be limited by law, by the indenture associated with 
that series of notes, or by the terms of other agreements to which we may be party at such time. If we fail to repurchase that 
series of notes as required by the terms of such notes, it would constitute an event of default under the indenture governing 
that series of notes which, in turn, may also constitute an event of default under other of our obligations. 

The term loans under the Credit Agreement bear interest at a floating rate, which is based on the London Interbank 
Offered Rate plus a fixed spread, and, therefore, any increase in interest rates would require us to pay additional interest, 
which may have an adverse effect on the value and liquidity of our debt and the market price of our common stock could 
decline.  The  interest  rate  under  the  Credit  Facility  is  also  subject  to  an  adjustment  in  conjunction  with  our  credit  rating 
downgrades or upgrades. Additionally, under the Credit Agreement, we are required to comply with affirmative and negative 
covenants, which include the maintenance of certain financial ratios, the details of which can be found in Note 7, “Debt” to 
the consolidated financial statements. 

 If we fail to comply with these covenants, we will be in default and our borrowings will become immediately due and 
payable. There can be no assurance that we will have sufficient financial resources or we will be able to arrange financing to 
repay our borrowings at such time. In addition, certain of our domestic subsidiaries under the Credit Agreement are required 
to guarantee our borrowings under the Credit Agreement. In the event that we default on our borrowings, these domestic 
subsidiaries shall be liable for our borrowings, which could disrupt our operations and result in a material adverse impact on 
our business, financial condition or stock price. 

Our leveraged capital structure may adversely affect our financial condition, results of operations and net income 

per share. 

Our issuance and maintenance of higher levels of indebtedness could have adverse consequences including, but not 

limited to:  

• 

• 

• 

• 

a negative impact on our ability to satisfy our future obligations; 

an increase in the portion of our cash flows that may have to be dedicated to increased interest and principal payments
that may not be available for operations, working capital, capital expenditures, acquisitions, investments, dividends,
stock repurchases, general corporate or other purposes;  

an impairment of our ability to obtain additional financing in the future; and

obligations to comply with restrictive and financial covenants as noted in the above risk factor and Note 7, “Debt”
to the consolidated financial statements. 

Our ability to satisfy our future expenses as well as our new debt obligations will depend on our future performance, 
which will be affected by financial, business, economic, regulatory and other factors. Furthermore, our future operations may 
not generate sufficient cash flows to enable us to meet our future expenses and service our debt obligations, which may impact 
our ability to manage our capital structure to preserve and maintain our investment grade rating. If our future operations do 
not generate sufficient cash flows, we may need to access the unfunded revolving credit facility of $500.0 million under the 
Credit Agreement or enter into new financing arrangements to obtain necessary funds. If we determine it is necessary to seek 
additional funding for any reason, we may not be able to obtain such funding or, if funding is available, we may not be able 

24 

 
 
 
 
 
 
 
 
 
to obtain it on acceptable terms. Any additional borrowing under the Credit Agreement will place further pressure on us to 
comply with the financial covenants. If we fail to make a payment associated with our debt obligations, we could be in default 
on such debt, and such a default could cause us to be in default on our other obligations.  

There can be no assurance that we will continue to declare cash dividends at all or in any particular amounts. 

Our Board of Directors first instituted a quarterly dividend during the fiscal year ended June 30, 2005. Since that time, 
we have announced a number of increases in the amount of our quarterly dividend level as well as payment of a special cash 
dividend that was declared and substantially paid in the second quarter of our fiscal year ended June 30, 2015. We intend to 
continue to pay quarterly dividends subject to capital availability and periodic determinations by our Board of Directors that 
cash dividends are in the best interest of our stockholders and are in compliance with all laws and agreements applicable to 
the declaration and payment of cash dividends by us. Future dividends may be affected by, among other factors: our views 
on potential future capital requirements for investments in acquisitions and the funding of our research and development; 
legal risks; stock repurchase programs; changes in federal and state income tax laws or corporate laws; changes to our business 
model;  and  our  increased  interest  and  principal  payments  required  by  our  outstanding  indebtedness  and  any  additional 
indebtedness that we may incur in the future. Our dividend payments may change from time to time, and we cannot provide 
assurance that we will continue to declare dividends at all or in any particular amounts. A reduction in our dividend payments 
could have a negative effect on our stock price. 

We  are  exposed  to  risks  related  to  our  commercial  terms  and  conditions,  including  our  indemnification  of  third 

parties, as well as the performance of our products. 

Although  our  standard  commercial  documentation  sets  forth  the  terms  and  conditions  that  we  intend  to  apply  to 
commercial transactions with our business partners, counterparties to such transactions may not explicitly agree to our terms 
and conditions. In situations where we engage in business with a third party without an explicit master agreement regarding 
the applicable terms and conditions, or where the commercial documentation applicable to the transaction is subject to varying 
interpretations, we may have disputes with those third parties regarding the applicable terms and conditions of our business 
relationship with them. Such disputes could lead to a deterioration of our commercial relationship with those parties, costly 
and time-consuming litigation, or additional concessions or obligations being offered by us to resolve such disputes, or could 
impact our revenue or cost recognition. Any of these outcomes could materially and adversely affect our business, financial 
condition and results of operations. 

In  addition,  in  our  commercial  agreements,  from  time  to  time  in  the  normal  course of  business we  indemnify  third 
parties with whom we enter into contractual relationships, including customers, suppliers and lessors, with respect to certain 
matters. We have agreed, under certain conditions, to hold these third parties harmless against specified losses, such as those 
arising from a breach of representations or covenants, other third party claims that our products when used for their intended 
purposes infringe the intellectual property rights of such other third parties, or other claims made against certain parties. We 
may  be  compelled  to  enter  into  or  accrue  for  probable  settlements  of  alleged  indemnification  obligations,  or  we  may  be 
subject  to  potential  liability  arising  from  our  customers’  involvements  in  legal  disputes.  In  addition,  notwithstanding  the 
provisions related to limitations on our liability that we seek to include in our business agreements, the counterparties to such 
agreements may dispute our interpretation or application of such provisions, and a court of law may not interpret or apply 
such provisions in our favor, any of which could result in an obligation for us to pay material damages to third parties and 
engage  in  costly  legal  proceedings.  It  is  difficult  to  determine  the  maximum  potential  amount  of  liability  under  any 
indemnification obligations, whether or not asserted, due to our limited history of prior indemnification claims and the unique 
facts and circumstances that are likely to be involved in any particular claim. Our business, financial condition and results of 
operations in a reported fiscal period could be materially and adversely affected if we expend significant amounts in defending 
or settling any purported claims, regardless of their merit or outcomes. 

We  are  also  exposed  to  potential  costs  associated  with  unexpected  product  performance  issues.  Our  products  and 
production processes are extremely complex and thus could contain unexpected product defects, especially when products 
are first introduced. Unexpected product performance issues could result in significant costs being incurred by us, including 

25 

 
increased service or warranty costs, providing product replacements for (or modifications to) defective products, litigation 
related to defective products, reimbursement for damages caused by our products, product recalls, or product write-offs or 
disposal costs. These costs could be substantial and could have an adverse impact upon our business, financial condition and 
operating results. In addition, our reputation with our customers could be damaged as a result of such product defects, which 
could reduce demand for our products and negatively impact our business. 

Furthermore, we occasionally enter into volume purchase agreements with our larger customers, and these agreements 
may  provide  for  certain  volume  purchase  incentives,  such  as  credits  toward  future  purchases.  We  believe  that  these 
arrangements are beneficial to our long-term business, as they are designed to encourage our customers to purchase higher 
volumes  of  our  products.  However,  these  arrangements  could  require  us  to  recognize  a  reduced  level  of  revenue  for  the 
products  that  are  initially  purchased,  to  account for  the potential  future credits or  other volume  purchase  incentives. Our 
volume purchase agreements require significant estimation for the amounts to be accrued depending upon the estimate of 
volume of future purchases. As such, we are required to update our estimates of the accruals on a periodic basis. Until the 
earnings  process  is  complete,  our  estimates  could  differ  in  comparison  to  actuals.  As  a  result,  these  volume  purchase 
arrangements, while expected to be beneficial to our business over time, could materially and adversely affect our results of 
operations in near-term periods, including the revenue we can recognize on product sales and therefore our gross margins. 

In addition, we may, in limited circumstances, enter into agreements that contain customer-specific commitments on 
pricing, tool reliability, spare parts stocking levels, response time and other commitments. Furthermore, we may give these 
customers limited audit or inspection rights to enable them to confirm that we are complying with these commitments. If a 
customer elects to exercise its audit or inspection rights, we may be required to expend significant resources to support the 
audit or inspection, as well as to defend or settle any dispute with a customer that could potentially arise out of such audit or 
inspection. To date, we have made no significant accruals in our consolidated financial statements for this contingency. While 
we have not in the past incurred significant expenses for resolving disputes regarding these types of commitments, we cannot 
make any assurance that we will not incur any such liabilities in the future. Our business, financial condition and results of 
operations  in  a  reported  fiscal  period  could  be  materially  and  adversely  affected  if  we  expend  significant  amounts  in 
supporting an audit or inspection, or defending or settling any purported claims, regardless of their merit or outcomes. 

There are risks associated with our receipt of government funding for research and development. 

We are exposed to additional risks related to our receipt of external funding for certain strategic development programs 
from various governments and government agencies, both domestically and internationally. Governments and government 
agencies  typically  have  the  right  to  terminate  funding  programs  at  any  time  in  their  sole  discretion,  or  a  project  may  be 
terminated by mutual agreement if the parties determine that the project’s goals or milestones are not being achieved, so there 
is no assurance that these sources of external funding will continue to be available to us in the future. In addition, under the 
terms  of  these  government  grants,  the  applicable  granting  agency  typically  has  the right  to  audit  the  costs  that  we incur, 
directly and indirectly, in connection with such programs. Any such audit could result in modifications to, or even termination 
of,  the  applicable  government  funding program.  For  example,  if  an  audit  were  to  identify  any  costs  as  being  improperly 
allocated to the applicable program, those costs would not be reimbursed, and any such costs that had already been reimbursed 
would have to be refunded. We do not know the outcome of any future audits. Any adverse finding resulting from any such 
audit could lead to penalties (financial or otherwise), termination of funding programs, suspension of payments, fines and 
suspension or prohibition from receiving future government funding from the applicable government or government agency, 
any of which could adversely impact our operating results, financial condition and ability to operate our business. 

We have recorded significant restructuring, inventory write-off and asset impairment charges in the past and may 

do so again in the future, which could have a material negative impact on our business. 

Historically, we recorded material restructuring charges related to our prior global workforce reductions, large excess 
inventory write-offs, and material impairment charges related to our goodwill and purchased intangible assets. During the 
fourth quarter of fiscal year ended 2015, we implemented a plan to reduce our global employee workforce to streamline our 
organization  and  business  processes  in  response  to  changing  customer  requirements  in  our  industry.  We  substantially 

26 

 
completed the global employee workforce reduction during the fiscal year ended June 30, 2016. Such workforce changes can 
also temporarily reduce workforce productivity, which could be disruptive to our business and adversely affect our results of 
operations. In addition, we may not achieve or sustain the expected cost savings or other benefits of our restructuring plans, 
or do so within the expected time frame. If we again restructure our organization and business processes, implement additional 
cost reduction actions or discontinue certain business operations, we may take additional, potentially material, restructuring 
charges related to, among other things, employee terminations or exit costs. We may also be required to write-off additional 
inventory if our product build plans or usage of service inventory decline. Also, as our lead times from suppliers increase 
(due to the increasing complexity of the parts and components they provide) and the lead times demanded by our customers 
decrease (due to the time pressures they face when introducing new products or technology or bringing new facilities into 
production), we may be compelled to increase our commitments, and therefore our risk exposure, to inventory purchases to 
meet our customers’ demands in a timely manner, and that inventory may need to be written-off if demand for the underlying 
product declines for any reason. Such additional write-offs could constitute material charges. 

In the past, we recorded a material charge related to the impairment of our goodwill and purchased intangible assets. 
Goodwill represents the excess of costs over the net fair value of net assets acquired in a business combination. Goodwill is 
not amortized, but is instead tested for impairment at least annually in accordance with authoritative guidance for goodwill. 
Purchased intangible assets with estimable useful lives are amortized over their respective estimated useful lives based on 
economic  benefit  if  known  or  using  the  straight-line  method,  and  are  reviewed  for  impairment  in  accordance  with 
authoritative  guidance  for  long-lived  assets.  The  valuation  of  goodwill  and  intangible  assets  requires  assumptions  and 
estimates of many critical factors, including revenue and market growth, operating cash flows, market multiples, and discount 
rates. A substantial decline in our stock price, or any other adverse change in market conditions, particularly if such change 
has  the  effect  of  changing  one  of  the  critical  assumptions  or  estimates  we  previously  used  to  calculate  the  value  of  our 
goodwill or intangible assets (and, as applicable, the amount of any previous impairment charge), could result in a change to 
the estimation of fair value that could result in an additional impairment charge. 

Any  such  additional  material  charges,  whether  related  to  restructuring  or  goodwill  or  purchased  intangible  asset 

impairment, may have a material negative impact on our operating results and related financial statements. 

We are exposed to risks related to our financial arrangements with respect to receivables factoring and banking 

arrangements. 

We enter into factoring arrangements with financial institutions to sell certain of our trade receivables and promissory 
notes from customers without recourse. In addition, we maintain bank accounts with several domestic and foreign financial 
institutions, any of which may prove not to be financially viable. If we were to stop entering into these factoring arrangements, 
our operating results, financial condition and cash flows could be adversely impacted by delays or failures in collecting trade 
receivables. However, by entering into these arrangements, and by engaging these financial institutions for banking services, 
we are exposed to additional risks. If any of these financial institutions experiences financial difficulties or is otherwise unable 
to honor the terms of our factoring or deposit arrangements, we may experience material financial losses due to the failure of 
such arrangements or a lack of access to our funds, any of which could have an adverse impact upon our operating results, 
financial condition and cash flows. 

We are subject to the risks of additional government actions in the event we were to breach the terms of any settlement 

arrangement into which we have entered. 

In connection with the settlement of certain government actions and other legal proceedings related to our historical 
stock option practices, we have explicitly agreed as a condition to such settlements that we will comply with certain laws, 
such as the books and records provisions of the federal securities laws. If we were to violate any such law, we might not only 
be subject to the significant penalties applicable to such violation, but our past settlements may also be impacted by such 
violation, which could give rise to additional government actions or other legal proceedings. Any such additional actions or 
proceedings  may  require  us  to  expend  significant  management  time  and  incur  significant  accounting,  legal  and  other 
expenses, and may divert attention and resources from the operation of our business. These expenditures and diversions, as 

27 

 
well as an adverse resolution of any such action or proceeding, could have a material adverse effect on our business, financial 
condition and results of operations. 

General Commercial, Operational, Financial and Regulatory Risks 

We  are  exposed  to  risks  associated  with  a  weakening  in  the  condition  of  the  financial  markets  and  the  global 

economy. 

The markets for semiconductors, and therefore our business, are ultimately driven by the global demand for electronic 
devices by consumers and businesses. Economic uncertainty frequently leads to reduced consumer and business spending, 
which  caused  our  customers  to  decrease,  cancel  or  delay  their  equipment  and  service  orders  from  us  in  the  economic 
slowdown during fiscal year 2009. In addition, the tightening of credit markets and concerns regarding the availability of 
credit that accompanied that slowdown made it more difficult for our customers to raise capital, whether debt or equity, to 
finance their purchases of capital equipment, including the products we sell. Reduced demand, combined with delays in our 
customers’ ability to obtain financing (or the unavailability of such financing), has at times in the past adversely affected our 
product and service sales and revenues and therefore has harmed our business and operating results, and our operating results 
and financial condition may again be adversely impacted if economic conditions decline from their current levels. 

In  addition,  a  decline  in  the  condition  of  the  global  financial  markets  could  adversely  impact  the  market  values  or 
liquidity of our investments. Our investment portfolio includes corporate and government securities, money market funds 
and  other  types  of  debt  and  equity  investments.  Although  we  believe  our  portfolio  continues  to  be  comprised  of  sound 
investments due to the quality and (where applicable) credit ratings, a decline in the capital and financial markets would 
adversely impact the market value of our investments and their liquidity. If the market value of such investments were to 
decline,  or  if  we  were  to  have  to  sell  some  of  our  investments  under  illiquid  market  conditions,  we  may  be  required  to 
recognize an impairment charge on such investments or a loss on such sales, either of which could have an adverse effect on 
our financial condition and operating results. 

If we are unable to timely and appropriately adapt to changes resulting from difficult macroeconomic conditions, our 

business, financial condition or results of operations may be materially and adversely affected. 

A majority of our annual revenues are derived from outside the United States, and we maintain significant operations 
outside the United States. We are exposed to numerous risks as a result of the international nature of our business and 
operations. 

A majority of our annual revenues are derived from outside the United States, and we maintain significant operations 
outside the United States. We expect that these conditions will continue in the foreseeable future. Managing global operations 
and sites located throughout the world presents a number of challenges, including but not limited to: 

•  managing cultural diversity and organizational alignment;

• 

• 

• 

• 

exposure to the unique characteristics of each region in the global semiconductor market, which can cause capital
equipment investment patterns to vary significantly from period to period; 

periodic local or international economic downturns; 

potential adverse tax consequences, including withholding tax rules that may limit the repatriation of our earnings, 
and higher effective income tax rates in foreign countries where we do business; 

government controls, either by the United States or other countries, that restrict our business overseas or the import
or export of semiconductor products or increase the cost of our operations; 

• 

compliance with customs regulations in the countries in which we do business;

28 

 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

• 

• 

• 

tariffs or other trade barriers (including those applied to our products or to parts and supplies that we purchase); 

political instability, natural disasters, legal or regulatory changes, acts of war or terrorism in regions where we have
operations or where we do business; 

fluctuations in interest and currency exchange rates may adversely impact our ability to compete on price with local 
providers or the value of revenues we generate from our international business. Although we attempt to manage
some of our near-term currency risks through the use of hedging instruments, there can be no assurance that such
efforts will be adequate; 

longer payment cycles and difficulties in collecting accounts receivable outside of the United States; 

difficulties in managing foreign distributors (including monitoring and ensuring our distributors’ compliance with
applicable laws); and 

• 

inadequate protection or enforcement of our intellectual property and other legal rights in foreign jurisdictions. 

Any of the factors above could have a significant negative impact on our business and results of operations. 

We might be involved in claims or disputes related to intellectual property or other confidential information that may 
be costly to resolve, prevent us from selling or using the challenged technology and seriously harm our operating results 
and financial condition. 

As is typical in the semiconductor equipment industry, from time to time we have received communications from other 
parties asserting the existence of patent rights, copyrights, trademark rights or other intellectual property rights which they 
believe cover certain of our products, processes, technologies or information. In addition, we occasionally receive notification 
from customers who believe that we owe them indemnification or other obligations related to intellectual property claims 
made  against  such  customers  by  third  parties.  With  respect  to  intellectual  property  infringement  disputes,  our  customary 
practice is to evaluate such infringement assertions and to consider whether to seek licenses where appropriate. However, we 
cannot  ensure  that  licenses  can  be  obtained  or,  if  obtained,  will  be  on  acceptable  terms  or  that  costly  litigation  or  other 
administrative proceedings will not occur. The inability to obtain necessary licenses or other rights on reasonable terms could 
seriously harm our results of operations and financial condition. Furthermore, we may potentially be subject to claims by 
customers,  suppliers  or  other  business  partners,  or  by  governmental  law  enforcement  agencies,  related  to  our  receipt, 
distribution  and/or  use  of  third-party  intellectual  property  or  confidential  information.  Legal  proceedings  and  claims, 
regardless of their merit, and associated internal investigations with respect to intellectual property or confidential information 
disputes  are  often  expensive  to  prosecute,  defend  or  conduct;  may  divert  management’s  attention  and  other  company 
resources; and/or may result in restrictions on our ability to sell our products, settlements on significantly adverse terms or 
adverse judgments for damages, injunctive relief, penalties and fines, any of which could have a significant negative effect 
on our business, results of operations and financial condition. There can be no assurance regarding the outcome of future 
legal proceedings, claims or investigations. The instigation of legal proceedings or claims, our inability to favorably resolve 
or settle such proceedings or claims, or the determination of any adverse findings against us or any of our employees in 
connection with such proceedings or claims could materially and adversely affect our business, financial condition and results 
of operations, as well as our business reputation. 

We  are  exposed  to  various  risks  related  to  the  legal,  regulatory  and  tax  environments  in  which  we  perform  our 

operations and conduct our business. 

We are subject to various risks related to compliance with new, existing, different, inconsistent or even conflicting laws, 
rules and regulations enacted by legislative bodies and/or regulatory agencies in the countries in which we operate and with 
which  we  must  comply,  including  environmental,  safety,  antitrust,  anti-corruption/anti-bribery,  unclaimed  property  and 
export control regulations. Our failure or inability to comply with existing or future laws, rules or regulations, or changes to 

29 

 
 
 
  
 
  
 
 
 
 
 
 
 
existing laws, rules or regulations (including changes that result in inconsistent or conflicting laws, rules or regulations), in 
the countries in which we operate could result in violations of contractual or regulatory obligations that may adversely affect 
our operating results, financial condition and ability to conduct our business. From time to time, we may receive inquiries or 
audit notices from governmental or regulatory bodies, or we may participate in voluntary disclosure programs, related to 
legal, regulatory or tax compliance matters, and these inquiries, notices or programs may result in significant financial cost 
(including investigation expenses, defense costs, assessments and penalties), reputational harm and other consequences that 
could materially and adversely affect our operating results and financial condition. 

Our  properties  and  many  aspects  of  our  business  operations  are  subject  to  various  domestic  and  international 
environmental  laws  and  regulations,  including  those  that  control  and  restrict  the  use,  transportation,  emission,  discharge, 
storage and disposal of certain chemicals, gases and other substances. Any failure to comply with applicable environmental 
laws, regulations or requirements may subject us to a range of consequences, including fines, suspension of certain of our 
business activities, limitations on our ability to sell our products, obligations to remediate environmental contamination, and 
criminal  and  civil  liabilities  or  other  sanctions.  In  addition,  changes  in  environmental  regulations  (including  regulations 
relating to climate change and greenhouse gas emissions) could require us to invest in potentially costly pollution control 
equipment, alter our manufacturing processes or use substitute (potentially more expensive and/or rarer) materials. Further, 
we use hazardous and other regulated materials that subject us to risks of strict liability for damages caused by any release, 
regardless of fault. We also face increasing complexity in our manufacturing, product design and procurement operations as 
we adjust to new and prospective requirements relating to the materials composition of our products, including restrictions 
on  lead  and  other  substances  and  requirements  to  track  the  sources  of  certain  metals  and  other  materials.  The  cost  of 
complying, or of failing to comply, with these and other regulatory restrictions or contractual obligations could adversely 
affect our operating results, financial condition and ability to conduct our business. 

In addition, we may from time to time be involved in legal proceedings or claims regarding employment, immigration, 
contracts, product performance, product liability, antitrust, environmental regulations, securities, unfair competition and other 
matters  (in  addition  to  proceedings  and  claims  related  to  intellectual  property  matters,  which  are  separately  discussed 
elsewhere  in  this  Item  1A).  These  legal  proceedings  and  claims,  regardless  of  their  merit,  may  be  time-consuming  and 
expensive to prosecute or defend, divert management’s attention and resources, and/or inhibit our ability to sell our products. 
There can be no assurance regarding the outcome of current or future legal proceedings or claims, which could adversely 
affect our operating results, financial condition and ability to operate our business. 

We depend on key personnel to manage our business effectively, and if we are unable to attract, retain and motivate 

our key employees, our sales and product development could be harmed. 

Our  employees  are vital  to  our  success,  and our key  management,  engineering  and other  employees  are difficult  to 
replace. We generally do not have employment contracts with our key employees. Further, we do not maintain key person 
life insurance on any of our employees. The expansion of high technology companies worldwide has increased demand and 
competition  for  qualified personnel. If we are  unable  to attract  and retain  key  personnel,  or  if  we  are  not  able  to attract, 
assimilate and retain additional highly qualified employees to meet our current and future needs, our business and operations 
could be harmed. 

We  outsource  a  number  of  services  to  third-party  service  providers,  which  decreases  our  control  over  the 
performance  of  these  functions.  Disruptions  or  delays  at  our  third-party  service  providers  could  adversely  impact  our 
operations. 

We  outsource  a  number  of  services,  including  our  transportation,  information  systems  management  and  logistics 
management of spare parts and certain accounting and procurement functions, to domestic and overseas third-party service 
providers. While outsourcing arrangements may lower our cost of operations, they also reduce our direct control over the 
services rendered. It is uncertain what effect such diminished control will have on the quality or quantity of products delivered 
or services rendered, on our ability to quickly respond to changing market conditions, or on our ability to ensure compliance 
with  all  applicable  domestic  and  foreign  laws  and  regulations.  In  addition,  many  of  these  outsourced  service  providers, 

30 

 
including certain hosted software applications that we use for confidential data storage, employ cloud computing technology 
for such storage. These providers’ cloud computing systems  may be susceptible to “cyber incidents,” such as intentional 
cyber attacks aimed at theft of sensitive data or inadvertent cyber-security compromises, which are outside of our control. If 
we do not effectively develop and manage our outsourcing strategies, if required export and other governmental approvals 
are not timely obtained, if our third-party service providers do not perform as anticipated or do not adequately protect our 
data  from  cyber-related  security  breaches,  or  if  there  are  delays  or  difficulties  in  enhancing  business  processes,  we  may 
experience operational difficulties (such as limitations on our ability to ship products), increased costs, manufacturing or 
service interruptions or delays, loss of intellectual property rights or other sensitive data, quality and compliance issues, and 
challenges  in  managing  our  product  inventory  or  recording  and  reporting  financial  and  management  information,  any  of 
which could materially and adversely affect our business, financial condition and results of operations. 

We are exposed to risks related to cybersecurity threats and cyber incidents. 

In  the  conduct  of  our  business,  we  collect,  use,  transmit  and  store  data  on  information  systems.  This  data  includes 
confidential information, transactional information and intellectual property belonging to us, our customers and our business 
partners, as well as personally-identifiable information of individuals. We allocate significant resources to network security, 
data encryption and other measures to protect our information systems and data from unauthorized access or misuse. Despite 
our ongoing efforts to enhance our network security measures, our information systems are susceptible to computer viruses, 
cyber-related  security  breaches  and  similar  disruptions  from  unauthorized  intrusions,  tampering,  misuse,  criminal  acts, 
including phishing, or other events or developments that we may be unable to anticipate or fail to mitigate and are subject to 
the inherent vulnerabilities of network security measures. We have experienced cyber-related attacks in the past, and may 
experience  cyber-related  attacks  in  the  future.  Our  security  measures  may  also  be  breached  due  to  employee  errors, 
malfeasance, or otherwise. Third parties may also attempt to influence employees, users, suppliers or customers to disclose 
sensitive information in order to gain access to our, our customers’ or business partners’ data. Because the techniques used 
to obtain unauthorized access to the information systems change frequently, and may not be recognized until launched against 
a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. 

Any  of  such  occurrences  could  result  in  disruptions  to  our  operations;  misappropriation,  corruption  or  theft  of 
confidential  information,  including  intellectual  property  and other  critical  data,  of KLA-Tencor,  our  customers  and  other 
business partners; misappropriation of funds and company assets; reduced value of our investments in research, development 
and engineering; litigation with, or payment of damages to, third parties; reputational damage; costs to comply with regulatory 
inquiries  or  actions;  data  privacy  issues;  costs  to  rebuild  our  internal  information  systems;  and  increased  cybersecurity 
protection and remediation costs. 

We carry insurance that provides some protection against the potential losses arising from a cybersecurity incident but 

it will not likely cover all such losses, and the losses that it does not cover may be significant. 

We rely upon certain critical information systems for our daily business operations. Our inability to use or access 

our information systems at critical points in time could unfavorably impact our business operations. 

Our global operations are dependent upon certain information systems, including telecommunications, the internet, our 
corporate intranet, network communications, email and various computer hardware and software applications. System failures 
or  malfunctioning,  such  as  difficulties  with  our  customer  relationship  management  (“CRM”)  system,  could  disrupt  our 
operations and our ability to timely and accurately process and report key components of our financial results. Our enterprise 
resource planning  (“ERP”)  system  is  integral  to  our  ability  to accurately  and  efficiently  maintain our  books  and records, 
record transactions, provide critical information to our management, and prepare our financial statements. Any disruptions 
or difficulties that may occur in connection with our ERP system or other systems (whether in connection with the regular 
operation, periodic enhancements, modifications or upgrades of such systems or the integration of our acquired businesses 
into such systems) could adversely affect our ability to complete important business processes, such as the evaluation of our 
internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002. Any of these events 
could have an adverse effect on our business, operating results and financial condition. 

31 

 
Acquisitions are an important element of our strategy but, because of the uncertainties involved, we may not find 
suitable acquisition candidates and we may not be able to successfully integrate and manage acquired businesses. We are 
also exposed to risks in connection with strategic alliances into which we may enter. 

In addition to our efforts to develop new technologies from internal sources, part of our growth strategy is to pursue 
acquisitions and acquire new technologies from external sources. As part of this effort, we may  make acquisitions of, or 
significant investments in, businesses with complementary products, services and/or technologies. There can be no assurance 
that we will find suitable acquisition candidates or that acquisitions we complete will be successful. In addition, we may use 
equity  to  finance  future  acquisitions,  which  would  increase  our  number  of  shares  outstanding  and  be  dilutive  to  current 
stockholders. 

If we are unable to successfully integrate and manage acquired businesses or if acquired businesses perform poorly, 
then our business and financial results may suffer. It is possible that the businesses we have acquired, as well as businesses 
that we may acquire in the future, may perform worse than expected or prove to be more difficult to integrate and manage 
than  anticipated.  In  addition,  we  may  lose  key  employees  of  the  acquired  companies.  As  a  result,  risks  associated  with 
acquisition  transactions  may  give  rise  to  a  material  adverse  effect  on  our  business  and  financial  results  for  a  number  of 
reasons, including: 

•  we may have to devote unanticipated financial and management resources to acquired businesses; 

• 

the combination of businesses may cause the loss of key personnel or an interruption of, or loss of momentum in,
the activities of our company and/or the acquired business; 

•  we may not be able to realize expected operating efficiencies or product integration benefits from our acquisitions; 

•  we may experience challenges in entering into new market segments for which we have not previously manufactured

and sold products; 

•  we may face difficulties in coordinating geographically separated organizations, systems and facilities; 

• 

the customers, distributors, suppliers, employees and others with whom the companies we acquire have business
dealings may have a potentially adverse reaction to the acquisition; 

•  we may have to write-off goodwill or other intangible assets; and 

•  we may incur unforeseen obligations or liabilities in connection with acquisitions.

At times, we may also enter into strategic alliances with customers, suppliers or other business partners with respect to 
development of technology and intellectual property. These alliances typically require significant investments of capital and 
exchange of proprietary, highly sensitive information. The success of these alliances depends on various factors over which 
we may have limited or no control and requires ongoing and effective cooperation with our strategic partners. Mergers and 
acquisitions and strategic alliances are inherently subject to significant risks, and the inability to effectively manage these 
risks could materially and adversely affect our business, financial condition and operating results. 

Disruption  of  our  manufacturing  facilities  or  other  operations,  or  in  the  operations  of  our  customers,  due  to 
earthquake, flood, other natural catastrophic events, health epidemics or terrorism could result in cancellation of orders, 
delays in deliveries or other business activities, or loss of customers and could seriously harm our business. 

We have significant manufacturing operations in the United States, Singapore, Israel, Germany and China. In addition, 
our  business  is  international  in  nature,  with our  sales,  service  and  administrative  personnel and  our  customers  located  in 
numerous countries throughout the world. Operations at our manufacturing facilities and our assembly subcontractors, as 
well as our other operations and those of our customers, are subject to disruption for a variety of reasons, including work 

32 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
stoppages, acts of war, terrorism, health epidemics, fire, earthquake, volcanic eruptions, energy shortages, flooding or other 
natural disasters. Such disruption could cause delays in, among other things, shipments of products to our customers, our 
ability to perform services requested by our customers, or the installation and acceptance of our products at customer sites. 
We cannot ensure that alternate means of conducting our operations (whether through alternate production capacity or service 
providers or otherwise) would be available if a major disruption were to occur or that, if such alternate means were available, 
they could be obtained on favorable terms. 

In  addition,  as  part  of  our  cost-cutting  actions,  we  have  consolidated  several  operating  facilities.  Our  California 
operations are now primarily centralized in our Milpitas facility. The consolidation of our California operations into a single 
campus could further concentrate the risks related to any of the disruptive events described above, such as acts of war or 
terrorism, earthquakes, fires or other natural disasters, if any such event were to impact our Milpitas facility. 

We are predominantly uninsured for losses and interruptions caused by terrorist acts and acts of war. If international 

political instability continues or increases, our business and results of operations could be harmed. 

The threat of terrorism targeted at, or acts of war in, the regions of the world in which we do business increases the 
uncertainty in our markets. Any act of terrorism or war that affects the economy or the semiconductor industry could adversely 
affect our business. Increased international political instability in various parts of the world, disruption in air transportation 
and further enhanced security measures as a result of terrorist attacks may hinder our ability to do business and may increase 
our costs of operations. We maintain significant manufacturing and research and development operations in Israel, an area 
that has historically experienced a high degree of political instability, and we are therefore exposed to risks associated with 
future instability in that region. Such instability could directly impact our ability to operate our business (or our customers’ 
ability  to  operate  their  businesses)  in  the  affected  region,  cause  us  to  incur  increased  costs  in  transportation,  make  such 
transportation unreliable, increase our insurance costs, and cause international currency markets to fluctuate. Such instability 
could also have the same effects on our suppliers and their ability to timely deliver their products. If international political 
instability continues or increases in any region in which we do business, our business and results of operations could be 
harmed. We are predominantly uninsured for losses and interruptions caused by terrorist acts and acts of war. 

We  self-insure  certain  risks including  earthquake  risk. If one or more  of  the uninsured  events  occurs,  we  could 

suffer major financial loss. 

We  purchase  insurance  to  help  mitigate  the  economic  impact  of  certain  insurable  risks;  however,  certain  risks  are 
uninsurable, are insurable only at significant cost or cannot be mitigated with insurance. Accordingly, we may experience a 
loss that is not covered by insurance, either because we do not carry applicable insurance or because the loss exceeds the 
applicable policy amount or is less than the deductible amount of the applicable policy. For example, we do not currently 
hold earthquake insurance. An earthquake could significantly disrupt our manufacturing operations, a significant portion of 
which are conducted in California, an area highly susceptible to earthquakes. It could also significantly delay our research 
and  engineering  efforts  on  new  products,  much  of  which  is  also  conducted  in  California.  We  take  steps  to  minimize  the 
damage that would be caused by an earthquake, but there is no certainty that our efforts will prove successful in the event of 
an earthquake. We self-insure earthquake risks because we believe this is a prudent financial decision based on our cash 
reserves and the high cost and limited coverage available in the earthquake insurance market. Certain other risks are also self-
insured either based on a similar cost-benefit analysis, or based on the unavailability of insurance. If one or more of the 
uninsured events occurs, we could suffer major financial loss. 

We are exposed to foreign currency exchange rate fluctuations. Although we hedge certain currency risks, we may 
still  be  adversely  affected  by  changes  in  foreign  currency  exchange  rates  or  declining  economic  conditions  in  these 
countries. 

We have some exposure to fluctuations in foreign currency exchange rates, primarily the Japanese Yen and the euro. We 
have  international  subsidiaries  that  operate  and  sell  our  products  globally.  In  addition,  an  increasing  proportion  of  our 
manufacturing activities are conducted outside of the United States, and many of the costs associated with such activities are 
denominated  in  foreign  currencies. We routinely  hedge our  exposures to  certain  foreign  currencies with  certain  financial 

33 

 
institutions  in  an  effort  to  minimize  the  impact  of  certain  currency  exchange  rate  fluctuations,  but  these  hedges  may  be 
inadequate to protect us from currency exchange rate fluctuations. To the extent that these hedges are inadequate, or if there 
are  significant  currency  exchange  rate fluctuations  in  currencies  for which we do  not have hedges  in place, our reported 
financial results or the way we conduct our business could be adversely affected. Furthermore, if a financial counterparty to 
our hedges experiences financial difficulties or is otherwise unable to honor the terms of the foreign currency hedge, we may 
experience material financial losses. 

We are exposed to fluctuations in interest rates and the market values of our portfolio investments; impairment of 
our investments could harm our earnings. In addition, we and our stockholders are exposed to risks related to the volatility 
of the market for our common stock. 

Our investment portfolio primarily consists of both corporate and government debt securities that are susceptible to 
changes in market interest rates and bond yields. As market interest rates and bond yields increase, those securities with a 
lower yield-at-cost show a mark-to-market unrealized loss. We believe we have the ability to realize the full value of all these 
investments upon maturity. However, an impairment of the fair market value of our investments, even if unrealized, must be 
reflected in our financial statements for the applicable period and may therefore have a material adverse effect on our results 
of operations for that period. 

In addition, the market price for our common stock is volatile and has fluctuated significantly during recent years. The 
trading price of our common stock could continue to be highly volatile and fluctuate widely in response to various factors, 
including without limitation conditions in the semiconductor industry and other industries in which we operate, fluctuations 
in  the  global  economy  or  capital  markets,  our  operating  results  or  other  performance  metrics,  or  adverse  consequences 
experienced by us as a result of any of the risks described elsewhere in this Item 1A. Volatility in the market price of our 
common stock could cause an investor in our common stock to experience a loss on the value of their investment in us and 
could also adversely impact our ability to raise capital through the sale of our common stock or to use our common stock as 
consideration to acquire other companies. 

We are exposed to risks in connection with tax and regulatory compliance audits in various jurisdictions. 

We are subject to tax and regulatory compliance audits (such as related to customs or product safety requirements) in 
various jurisdictions, and such jurisdictions may assess additional income or other taxes, penalties, fines or other prohibitions 
against us. Although we believe our tax estimates are reasonable and that our products and practices comply with applicable 
regulations, the final determination of any such audit and any related litigation could be materially different from our historical 
income tax provisions and accruals related to income taxes and other contingencies. The results of an audit or litigation could 
have a material adverse effect on our operating results or cash flows in the period or periods for which that determination is 
made. 

A change in our effective tax rate can have a significant adverse impact on our business. 

We  earn  profits  in,  and  are  therefore  potentially  subject  to  taxes  in,  the  U.S.  and  numerous  foreign  jurisdictions, 
including Singapore, Israel and the Cayman Islands, the countries in which we earn the majority of our non-U.S. profits. Due 
to economic, political or other conditions, tax rates in those jurisdictions may be subject to significant change. A number of 
factors may adversely impact our future effective tax rates, such as the jurisdictions in which our profits are determined to be 
earned and taxed; changes in the tax rates imposed by those jurisdictions; expiration of tax holidays in certain jurisdictions 
that are not renewed; the resolution of issues arising from tax audits with various tax authorities; changes in the valuation of 
our deferred tax assets and liabilities; adjustments to estimated taxes upon finalization of various tax returns; increases in 
expenses  not  deductible  for  tax  purposes,  including  write-offs  of  acquired  in-process  research  and  development  and 
impairment  of  goodwill  in  connection  with  acquisitions;  changes  in  available  tax  credits;  changes  in  stock-based 
compensation expense; changes in tax laws or the interpretation of such tax laws (for example, proposals for fundamental 
United States international tax reform); changes in generally accepted accounting principles; and the repatriation of earnings 
from outside the United States for which we have not previously provided for United States taxes. A change in our effective 
tax rate can materially and adversely impact our results from operations. 

34 

 
Compliance  with  federal  securities  laws,  rules  and  regulations,  as  well  as  NASDAQ  requirements,  has  become 
increasingly complex, and the significant attention and expense we must devote to those areas may have an adverse impact 
on our business. 

Federal securities laws, rules and regulations, as well as NASDAQ rules and regulations, require companies to maintain 
extensive  corporate  governance  measures,  impose  comprehensive  reporting  and  disclosure  requirements,  set  strict 
independence  and  financial  expertise  standards  for  audit  and  other  committee  members  and  impose  civil  and  criminal 
penalties for companies and their chief executive officers, chief financial officers and directors for securities law violations. 
These laws, rules and regulations have increased, and in the future are expected to continue to increase, the scope, complexity 
and cost of our corporate governance, reporting and disclosure practices, which could harm our results of operations and 
divert management’s attention from business operations. 

A change in accounting standards or practices or a change in existing taxation rules or practices (or changes in 
interpretations of such standards, practices or rules) can have a significant effect on our reported results and may even 
affect reporting of transactions completed before the change is effective. 

New accounting standards and taxation rules and varying interpretations of accounting pronouncements and taxation 
rules have occurred and will continue to occur in the future. Changes to (or revised interpretations or applications of) existing 
accounting standards or tax rules or the questioning of current or past practices may adversely affect our reported financial 
results or the way we conduct our business. For example, in May 2014, the Financial Accounting Standards Board (“FASB”) 
issued an accounting standard update regarding revenue from contracts with customers, and in February 2016, the FASB 
issued an accounting standard update which amends the existing accounting standards for leases. Adoption of new standards 
may require changes to our processes, accounting systems, and internal controls. Difficulties encountered during adoption 
could result in internal control deficiencies or delay the reporting of our financial results.

Portions of this property are sublet, are vacant and marketed to sublease, or are leased to third parties. 

We own the building at our location in Serangoon, Singapore, but the land on which this building resides is leased. 

As of June 30, 2017, we owned or leased a total of approximately 2.1 million square feet of space worldwide, including 
the locations listed above and office space for smaller sales and service offices in several locations throughout the world. Our 
operating leases expire at various times through November 7, 2028, subject to renewal, with some of the leases containing 
renewal option clauses at the fair market value, for additional periods up to five years. Additional information regarding these 
leases  is  incorporated  herein  by  reference  to  Note  13,  “Commitments  and  Contingencies”  to  the  consolidated  financial 
statements. We believe our properties are adequately maintained and suitable for their intended use and that our production 
facilities have capacity adequate for our current needs.

__________ 

(1)  Our net income decreased to $366.2 million in the fiscal year ended June 30, 2015, primarily as a result of the impact of
the pre-tax net loss of $131.7 million for the loss on extinguishment of debt and certain one-time expenses of $2.5 million 
associated with the leveraged recapitalization that was completed during the three months ended December 31, 2014. 

(2)  We  adopted  the  accounting  standards  update  regarding  classification  of  deferred  taxes  on  a  prospective  basis  at  the
beginning of the fourth quarter of fiscal year ended 2016. Upon adoption, approximately $218.0 million in net current
deferred tax assets were reclassified to noncurrent. No prior periods were retrospectively adjusted.  

(3)  Our  long-term  debt  increased  to  $3.17  billion  at  the  end  of  fiscal  year  ended  June  30,  2015,  because,  as  part  of  the
leveraged recapitalization plan, we issued $2.50 billion aggregate principal amount of senior, unsecured long-term notes 
(collectively referred to as “Senior Notes”), entered into $750.0 million of five-year senior unsecured prepayable term
loans  and  a  $500.0  million  unfunded  revolving  credit  facility  and  redeemed  our  $750.0  million  aggregate  principal
amount of 6.900% Senior Notes due in 2018 (the “2018 Notes”). Refer to Note 7, “Debt” for additional details. Our total
stockholders’ equity decreased to $421.4 million at the end of fiscal year ended June 30, 2015, because, as part of our
leveraged recapitalization plan, we declared a special cash dividend of approximately $2.76 billion. Refer to Note 8,
“Equity and Long-term Incentive Compensation Plans” to the consolidated financial statements for additional details.

MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND 
RESULTS OF OPERATIONS 

The following discussion of our financial condition and results of operations should be read in conjunction with our 
Consolidated Financial Statements and the related notes included in Item 8, “Financial Statements and Supplementary Data,” 
in  this  Annual  Report  on  Form  10-K.  This  discussion  contains  forward-looking  statements,  which  involve  risks  and 
uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result 
of certain factors, including but not limited to those discussed in Item 1A, “Risk Factors” and elsewhere in this Annual Report 
on Form 10-K. (See “Special Note Regarding Forward-Looking Statements.”) 

CRITICAL ACCOUNTING ESTIMATES AND POLICIES 

The preparation of our consolidated financial statements in conformity with accounting principles generally accepted 
in the United States of America requires management to make estimates and assumptions in applying our accounting policies 
that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and 
liabilities.  We base  these  estimates  and  assumptions on historical  experience,  and  evaluate  them  on an on-going basis  to 
ensure that they remain reasonable under current conditions. Actual results could differ from those estimates. We discuss the 
development and selection of the critical accounting estimates with the Audit Committee of our Board of Directors on a 
quarterly  basis,  and  the  Audit  Committee  has  reviewed  our  related  disclosure  in  this  Annual  Report  on  Form  10-K.  The 
accounting policies that reflect our more significant estimates, judgments and assumptions and which we believe are the most 
critical to aid in fully understanding and evaluating our reported financial results include the following:  

Revenue  Recognition.  We  recognize  revenue  when  persuasive  evidence  of  an  arrangement  exists,  delivery  has 
occurred or services have been rendered, the selling price is fixed or determinable, and collectibility is reasonably assured. 
We  derive  revenue  from  three  sources—sales  of  systems,  spare  parts  and  services.  In  general,  we  recognize  revenue  for 
systems when the system has been installed, is operating according to predetermined specifications and is accepted by the 
customer.  When  we  have  demonstrated  a  history  of  successful  installation  and  acceptance,  we  recognize  revenue  upon 
delivery and customer acceptance. Under certain circumstances, however, we recognize revenue prior to acceptance from the 
customer, as follows: 

•  When  the  customer  fab  has  previously  accepted  the  same  tool,  with  the  same  specifications,  and  when  we  can

objectively demonstrate that the tool meets all of the required acceptance criteria. 

•  When system sales to independent distributors have no installation requirement, contain no acceptance agreement,

and 100% of the payment is due based upon shipment. 

•  When the installation of the system is deemed perfunctory. 

•  When the customer withholds acceptance due to issues unrelated to product performance, in which case revenue is

recognized when the system is performing as intended and meets predetermined specifications. 

In circumstances in which we recognize revenue prior to installation, the portion of revenue associated with installation 

is deferred based on estimated fair value, and that revenue is recognized upon completion of the installation. 

In  many  instances,  products  are  sold  in  stand-alone  arrangements.  Services  are  sold separately  through renewals of 
annual maintenance contracts. We have multiple element revenue arrangements in cases where certain elements of a sales 
arrangement are not delivered and accepted in one reporting period. To determine the relative fair value of each element in a 
revenue arrangement, we allocate arrangement consideration based on the selling price hierarchy. For substantially all of the 
arrangements  with  multiple  deliverables  pertaining  to  products  and  services,  we  use  vendor-specific  objective  evidence 
(“VSOE”) or  third-party  evidence  (“TPE”) to  allocate  the  selling price  to  each  deliverable. We  determine  TPE  based  on 
historical prices charged for products and services when sold on a stand-alone basis. When we are unable to establish relative 
selling price using VSOE or TPE, we use estimated selling price (“ESP”) in our allocation of arrangement consideration. The 
41 

 
 
 
 
 
 
 
 
 
objective of ESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-
alone basis. ESP could potentially be used for new or customized products. We regularly review relative selling prices and 
maintain internal controls over the establishment and updates of these estimates.  

In a multiple element revenue arrangement, we defer revenue recognition associated with the relative fair value of each 
undelivered  element  until  that  element  is  delivered  to  the  customer.  To be  considered a  separate  element,  the  product  or 
service in question must represent a separate unit of accounting, which means that such product or service must fulfill the 
following  criteria:  (a)  the  delivered  item(s)  has  value  to  the  customer  on  a  stand-alone  basis;  and  (b)  if  the  arrangement 
includes  a  general  right  of  return  relative  to  the  delivered  item(s),  delivery  or  performance  of  the  undelivered  item(s)  is 
considered probable and substantially in our control. If the arrangement does not meet all the above criteria, the entire amount 
of the sales contract is deferred until all elements are accepted by the customer. 

Trade-in rights are occasionally granted to customers to trade in tools in connection with subsequent purchases. We 
estimate the value of the trade-in right and reduce the revenue recognized on the initial sale. This amount is recognized at the 
earlier of the exercise of the trade-in right or the expiration of the trade-in right. 

We enter into volume purchase agreements with some of our customers. We accrue the estimated credits earned by our 
customers for such incentives, and in situations when the credit levels vary depending upon sales volume, we update our 
accrual based on the amount that we estimate to be purchased pursuant to the volume purchase agreements. Accruals for 
customer credits are recorded as an offset to revenue or deferred revenue. 

Spare  parts  revenue  is  recognized  when  the  product  has  been  shipped,  risk  of  loss  has  passed  to  the  customer  and 

collection of the resulting receivable is probable. 

Service and maintenance contract revenue is recognized ratably over the term of the maintenance contract. Revenue 
from services performed in the absence of a maintenance contract, including consulting and training revenue, is recognized 
when the related services are performed and collectibility is reasonably assured. 

We sell stand-alone software that is subject to software revenue recognition guidance. We periodically review selling 
prices to determine whether VSOE exists, and in situations where we are unable to establish VSOE for undelivered elements 
such as post-contract service, revenue is recognized ratably over the term of the service contract.  

We also defer the fair value of non-standard warranty bundled with equipment sales as unearned revenue. Non-standard 
warranty includes services incremental to the standard 40-hour per week coverage for 12 months. Non-standard warranty is 
recognized ratably as revenue when the applicable warranty term period commences. 

The deferred system profit balance equals the value of products that have been shipped and billed to customers which 
have not met our revenue recognition criteria, less applicable product and warranty costs. Deferred system profit does not 
include  the  profit  associated  with  product  shipments  to  certain  customers  in  Japan,  to  whom  title  does  not  transfer  until 
customer acceptance. Shipments to such customers in Japan are classified as inventory at cost until the time of acceptance. 

We enter into sales arrangements that may consist of multiple deliverables of our products and services where certain 
elements of the sales arrangement are not delivered and accepted in one reporting period. Judgment is required to properly 
identify the accounting units of the multiple deliverable transactions and to determine the manner in which revenue should 
be  allocated  among  the  accounting  units.  Additionally,  judgment  is  required  to  interpret  various  commercial  terms  and 
determine when all criteria of revenue recognition have been met in order for revenue recognition to occur in the appropriate 
accounting period. While changes in the allocation of the estimated selling price between the accounting units will not affect 
the amount of total revenue recognized for a particular arrangement, any material changes in these allocations could impact 
the timing of revenue recognition, which could have a material effect on our financial position and results of operations. 

Inventories. Inventories are stated at the lower of cost (on a first-in, first-out basis) or market. Demonstration units are 
stated at their manufacturing cost and written down to their net realizable value. Our manufacturing overhead standards for 
product costs are calculated assuming full absorption of forecasted spending over projected volumes, adjusted for excess 

42 

 
capacity.  Abnormal  inventory  costs  such  as  costs  of  idle  facilities,  excess  freight  and  handling  costs,  and  spoilage  are 
recognized  as  current  period  charges.  We  write  down  product  inventory  based  on  forecasted  demand  and  technological 
obsolescence and service spare parts inventory based on forecasted usage. These factors are impacted by market and economic 
conditions, technology changes, new product introductions and changes in strategic direction and require estimates that may 
include uncertain elements. Actual demand may differ from forecasted demand, and such differences may have a material 
effect on recorded inventory values. 

Warranty. We provide standard warranty coverage on our systems for 40 hours per week for 12 months, providing 
labor  and  parts  necessary  to  repair  and  maintain  the  systems  during  the  warranty  period.  We  account  for  the  estimated 
warranty cost as a charge to costs of revenues when revenue is recognized. The estimated warranty cost is based on historical 
product performance and field expenses. Utilizing actual service records, we calculate the average service hours and parts 
expense per system and apply the actual labor and overhead rates to determine the estimated warranty charge. We update 
these estimated charges on a regular basis. The actual product performance and/or field expense profiles may differ, and in 
those cases we adjust our warranty accruals accordingly. See Note 13, “Commitments and Contingencies” to the Consolidated 
Financial Statements for additional details. 

Allowance for Doubtful Accounts. A majority of our accounts receivables are derived from sales to large multinational 
semiconductor manufacturers throughout the world. In order to monitor potential credit losses, we perform ongoing credit 
evaluations of our customers’ financial condition. An allowance for doubtful accounts is maintained for probable credit losses 
based upon our assessment of the expected collectibility of the accounts receivable. The allowance for doubtful accounts is 
reviewed on a quarterly basis to assess the adequacy of the allowance. We take into consideration (1) any circumstances of 
which we are aware of a customer’s inability to meet its financial obligations; and (2) our judgments as to prevailing economic 
conditions in the industry and their impact on our customers. If circumstances change, such that the financial conditions of 
our customers are adversely affected and they are unable to meet their financial obligations to us, we may need to record 
additional allowances, which would result in a reduction of our net income. 

Accounting  for  Stock-Based  Compensation  Plans.  We  account  for  stock-based  awards  granted  to  employees  for 
services based on the fair value of those awards. The fair value of stock-based awards is measured at the grant date and is 
recognized as expense over the employee’s requisite service period. The fair value for restricted stock units granted without 
“dividend equivalent” rights is determined using the closing price of our common stock on the grant date, adjusted to exclude 
the present value of dividends which are not accrued on the restricted stock units. The fair value for restricted stock units 
granted with “dividend equivalent” rights is determined using the closing price of our common stock on the grant date. The 
award holder is not entitled to receive payments under dividend equivalent rights unless the associated restricted stock unit 
award vests (i.e., the award holder is entitled to receive credits, payable in cash or shares of our common stock, equal to the 
cash dividends that would have been received on the shares of our common stock underlying the restricted stock units had 
the shares been issued and outstanding on the dividend record date, but such dividend equivalents are only paid subject to the 
recipient  satisfying  the  vesting  requirements  of  the  underlying  award).  Additionally,  we  estimate  forfeitures  based  on 
historical experience and revise those estimates in subsequent periods if actual forfeitures differ from the estimated amounts. 
The fair value is determined using a Black-Scholes valuation model for purchase rights under our Employee Stock Purchase 
Plan. The Black-Scholes option-pricing model requires the input of assumptions, including the option’s expected term and 
the expected price volatility of the underlying stock. The expected stock price volatility assumption is based on the market-
based historical implied volatility from traded options of our common stock.  

Accounting for Cash-Based Long-Term Incentive Compensation. Cash-based long-term incentive (“Cash LTI”) 
awards issued to employees under our Cash LTI program vest in three or four equal installments, with one-third or one-fourth 
of the aggregate amount of the Cash LTI award vesting on each yearly anniversary of the grant date over a three or four-year 
period. In order to receive payments under a Cash LTI award, participants must remain employed by us as of the applicable 
award vesting date. Compensation expense related to the Cash LTI awards is recognized over the vesting term, which is 
adjusted for the impact of estimated forfeitures. 

43 

 
Contingencies and Litigation. We are subject to the possibility of losses from various contingencies. Considerable 
judgment is necessary to estimate the probability and amount of any loss from such contingencies. An accrual is made when 
it  is  probable  that  a  liability  has  been  incurred  or  an  asset  has  been  impaired  and  the  amount  of  loss  can  be  reasonably 
estimated. We accrue a liability and recognize as expense the estimated costs expected to be incurred over the next twelve 
months to defend or settle asserted and unasserted claims existing as of the balance sheet date. See Note 13, “Commitments 
and  Contingencies”  and  Note  14,  “Litigation  and  Other  Legal  Matters”  to  the  Consolidated  Financial  Statements  for 
additional details. 

Goodwill and Intangible Assets. We assess goodwill for impairment annually as well as whenever events or changes 
in circumstances indicate that the carrying value may not be recoverable. Long-lived purchased intangible assets are tested 
for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. 
See Note 6,  “Goodwill  and Purchased  Intangible Assets”  to  the  Consolidated  Financial  Statements  for  additional details. 
Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets 
acquired in each business combination. We performed our annual qualitative assessment of the goodwill by reporting unit in 
our second quarter of fiscal year ended June 30, 2017 and concluded that there was no impairment. There have been no 
significant events or circumstances affecting the valuation of goodwill subsequent to our annual impairment test. The next 
annual evaluation of the goodwill by reporting unit will be performed in the second quarter of the fiscal year ending June 30, 
2018. 

If we were to encounter challenging economic conditions, such as a decline in our operating results, an unfavorable 
industry  or  macroeconomic  environment,  a  substantial  decline  in  our  stock  price,  or  any  other  adverse  change  in  market 
conditions,  we  may  be  required  to  perform  the  two-step  quantitative  goodwill  impairment  analysis.  In  addition,  if  such 
conditions  have  the  effect  of  changing  one  of  the  critical  assumptions  or  estimates  we  use  to  calculate  the  value  of  our 
goodwill or intangible assets, we may be required to record goodwill and/or intangible asset impairment charges in future 
periods. It is not possible at this time to determine if any such future impairment charge would occur or, if it does, whether 
such charge would be material to our results of operations. 

Income Taxes. We account for income taxes in accordance with the authoritative guidance, which requires that deferred 
tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and 
tax bases of recorded assets and liabilities. The guidance also requires that deferred tax assets be reduced by a valuation 
allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. We have determined that a 
valuation allowance is necessary against a portion of the deferred tax assets, but we anticipate that our future taxable income 
will be sufficient to recover the remainder of our deferred tax assets. However, should there be a change in our ability to 
recover our deferred tax assets that are not subject to a valuation allowance, we could be required to record an additional 
valuation allowance against such deferred tax assets. This would result in an increase to our tax provision in the period in 
which we determine that the recovery is not probable. 

On  a  quarterly  basis,  we  provide  for  income  taxes  based  upon  an  estimated  annual  effective  income  tax  rate.  The 
effective tax rate is highly dependent upon the geographic composition of worldwide earnings, tax regulations governing 
each region, availability of tax credits and the effectiveness of our tax planning strategies. We carefully monitor the changes 
in many factors and adjust our effective income tax rate on a timely basis. If actual results differ from these estimates, this 
could have a material effect on our financial condition and results of operations. 

In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax 
regulations.  In  accordance  with  the  authoritative  guidance  on  accounting  for  uncertainty  in  income  taxes,  we  recognize 
liabilities for uncertain tax positions based on the two-step process. The first step is to evaluate the tax position for recognition 
by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained 
in audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit 
as the largest amount that is more than 50% likely of being realized upon ultimate settlement. We reevaluate these uncertain 
tax  positions  on  a  quarterly  basis.  This  evaluation  is  based  on  factors  including,  but  not  limited  to,  changes  in  facts  or 

44 

 
circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any change in these factors 
could result in the recognition of a tax benefit or an additional charge to the tax provision. 

Valuation  of  Marketable  Securities.  Our  investments  in  available-for-sale  securities  are  reported  at  fair  value. 
Unrealized gains related to increases in the fair value of investments and unrealized losses related to decreases in the fair 
value are included in accumulated other comprehensive income (loss), net of tax, as reported on our Consolidated Statements 
of  Stockholders’  Equity.  However,  changes  in  the  fair  value  of  investments  impact  our  net  income  only  when  such 
investments are sold or an impairment charge is recognized. Realized gains and losses on the sale of securities are determined 
by specific identification of the security’s cost basis. We periodically review our investment portfolio to determine if any 
investment is other-than-temporarily impaired due to changes in credit risk or other potential valuation concerns, which would 
require  us  to  record  an  impairment  charge  in  the  period  during  which  any  such  determination  is  made.  In  making  this 
judgment, we evaluate, among other things, the duration of the investment, the extent to which the fair value of an investment 
is less than its cost, the credit rating and any changes in credit rating for the investment, default and loss rates of the underlying 
collateral, structure and credit enhancements to determine if a credit loss may exist. Our assessment that an investment is not 
other-than-temporarily  impaired  could  change  in  the  future  due  to  new  developments  or  changes  in  our  strategies  or 
assumptions related to any particular investment.

EXECUTIVE SUMMARY 

KLA-Tencor Corporation is a leading supplier of process control and yield management solutions for the semiconductor 
and related nanoelectronics industries. Our broad portfolio of inspection and metrology products, and related service, software 
and other offerings primarily supports integrated circuit (“IC” or “chip”) manufacturers throughout the entire semiconductor 
fabrication  process,  from  research  and  development  to  final  volume  production.  We  provide  leading-edge  equipment, 
software  and  support  that  enable  IC  manufacturers  to  identify,  resolve  and  manage  significant  advanced  technology 
manufacturing process challenges and obtain higher finished product yields at lower overall cost. In addition to serving the 
semiconductor industry, we also provide a range of technology solutions to a number of other high technology industries, 
including advanced packaging, light emitting diode (“LED”), power devices, compound semiconductor, and data storage 
industries, as well as general materials research.  

Our products and services are used by the vast majority of bare wafer, IC, lithography reticle (“reticle” or “mask”) and 
disk manufacturers around the world. Our products, services and expertise are used by our customers to measure, detect, 
analyze and resolve critical product defects that arise in that environment in order to control nanometric level manufacturing 
processes. Our revenues are driven largely by our customers’ spending on capital equipment and related maintenance services 
necessary  to  support  key  transitions  in  their  underlying  product  technologies,  or  to  increase  their  production  volumes  in 
response to market demand or expansion plans. Our semiconductor customers generally operate in one or more of the three 
major semiconductor markets - memory, foundry and logic. All three of these markets are characterized by rapid technological 
changes  and  sudden  shifts  in  end-user demand, which  influence  the  level  and pattern of  our  customers’  spending on  our 
products  and  services.  Although  capital  spending  in  all  three  semiconductor  markets  has  historically  been  cyclical,  the 
demand for more advanced and lower cost chips used in a growing number of consumer electronics, communications, data 
processing, and industrial and automotive products has resulted over the long term in a favorable demand environment for 
our process control and yield management solutions, particularly in the foundry and logic markets, which have higher levels 
of process control adoption than the memory market.  

45 

 
 
 
As we are a supplier to the global semiconductor and semiconductor-related industries, our customer base continues to 
become more highly concentrated over time, thereby increasing the potential impact of a sudden change in capital spending 
by a major customer on our revenues and profitability. As our customer base becomes increasingly more concentrated, large 
orders from a relatively limited number of customers account for a substantial portion of our sales, which potentially exposes 
us to more volatility for revenues and earnings. In the global semiconductor and semiconductor-related industries, China is 
emerging as a major region for manufacturing of logic and memory chips, adding to its role as the world’s largest consumer 
of  ICs.  Government  initiatives  are  propelling  China  to  expand  its  domestic  manufacturing  capacity  and  attracting 
semiconductor  manufacturers  from  Taiwan,  Korea,  Japan and  the  US.  China  is  currently  seen  as  an  important  long-term 
growth region for the semiconductor capital equipment sector. We are also subject to the cyclical capital spending that has 
historically characterized the semiconductor and semiconductor-related industries. The timing, length, intensity and volatility 
of the capacity-oriented capital spending cycles of our customers are unpredictable.  

The  semiconductor  industry  has  also  been  characterized  by  constant  technological  innovation.  Currently,  there  are 
multiple drivers for growth in the industry with increased demand for chips providing computation power and connectivity 
for AI applications and support for mobile devices at the leading edge of foundry chip manufacturing. Qualification of early 
EUV lithography processes and equipment is driving growth at leading logic/foundry and DRAM manufacturers. Expansion 
of the IoT together with increasing acceptance of ADAS in anticipation of the introduction of autonomous cars have begun 
to accelerate legacy-node technology conversions and capacity expansions. Intertwined in these areas, spurred by data storage 
and  connectivity  needs,  is  the  growth  in demand  for  memory  chips. On the  other hand,  higher design  costs for  the most 
advanced ICs could economically constrain leading-edge manufacturing technology customers to focus their resources on 
only the large technologically advanced products and applications. We believe that, over the long term, our customers will 
continue to invest in advanced technologies and new materials to enable smaller design rules and higher density applications 
that  fuel  demand  for  process  control  equipment,  although  the  growth  for  such  equipment  may  be  adversely  impacted  by 
higher design costs for advanced ICs, reuse of installed products, and delays in production ramps by our customers in response 
to higher costs and technical challenges at more advanced technology nodes. 

The demand for our products and our revenue levels are driven by our customers’ needs to solve the process challenges 
that  they  face as  they  adopt new  technologies  required  to  fabricate  advanced ICs  that are  incorporated  into  sophisticated 
mobile  devices.  The  timing  for  our  customers  in  ordering  and  taking  delivery  of  process  control  and  yield  management 
equipment is also determined by our customers’ requirements to meet the next generation production ramp schedules, and 
the timing for capacity expansion to meet end customer demand. Our earnings will depend not only on our revenue levels, 
but also on the amount of research and development spending required to meet our customers’ technology roadmaps. We 
have maintained production volumes and capacity to meet anticipated customer requirements and remain at risk of incurring 
significant  inventory-related  and  other  restructuring  charges  if  business  conditions  deteriorate.  Over  the  past  year,  our 
customers have taken delivery of higher volumes of process control equipment than they did in the previous year. However, 
any delay or push out by our customers in taking delivery of process control and yield management equipment may cause 
earnings volatility, due to increases in the risk of inventory related charges as well as timing of revenue recognition. 

On October 20, 2015, we entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement” 
or “Merger”) with Lam Research Corporation (“Lam Research”) which was subject to regulatory approvals. On October 5, 
2016,  we  mutually  agreed  to  terminate  the  Merger  Agreement  and  no  termination  fees  were  payable  by  either  party  in 
connection with the termination.

Year ended June 30, 

Total revenues during the fiscal year ended June 30, 2017 increased by 17% compared to the fiscal year ended June 
30, 2016. Our year over year revenue growth reflected increases from sales of both our inspection and metrology products as 
our customers continue to invest in process control and services. Increased revenues during the fiscal year ended June 30, 
2017 were also driven by strong demand from our foundry customers and an increase in the number of post-warranty systems 
installed at our customers’ sites over this time period for our service revenues. 

Total revenues during the fiscal year ended June 30, 2016 increased by 6% compared to the fiscal year ended June 30, 
2015. Our year over year revenue growth reflected increases from sales of both our inspection and metrology products as our 
customers continue to invest in process control and services. Increased revenues during the fiscal year ended June 30, 2016 
were also driven by the introduction of our new generation of inspection products as well strong demand from our foundry 
customers and an increase in the number of post-warranty systems installed at our customers’ sites over this time period for 
our service revenues.

Product revenues 

Our business is affected by the concentration of our customer base and our customers’ capital equipment procurement 
schedules as a result of their investment plans. Our product revenues in any particular period are significantly impacted by 
the  amount  of  new  orders  that  we  receive  during  that  period  and,  depending  upon  the  duration  of  manufacturing  and 
installation cycles, in the preceding period. 

Product revenues increased by 20% in the fiscal year ended June 30, 2017 compared to the fiscal year ended June 30, 
2016, primarily due to growth in revenues from our customers in Korea, Taiwan, and Europe & Israel. Our year over year 
increase  in  our  product  revenues  were  primarily  driven  by  strong  demand  for  our  inspection  and  metrology  products, 
increased  investments  by  our  foundry  customers  to  support  their  new  device  architectures  and  process  technologies  for 
capacity-related expansion, and sales of our next generation inspection products.  

Product revenues increased by 6% in the fiscal year ended June 30, 2016 compared to the fiscal year ended June 30, 
2015, primarily due to growth in revenues from our customers in China, Taiwan and Japan, partially offset by lower revenues 
from our customers in North America, Korea, Rest of Asia and Europe & Israel. The year over year increase in our product

revenues were primarily driven by strong demand for our inspection and metrology products, the introduction of our new 
generation of inspection products and the expansion of semiconductor investments in Asia, particularly in China and Taiwan 
from our foundry customers. 

Service revenues 

Service revenues are generated from maintenance contracts, as well as billable time and material service calls made to 
our customers after the expiration of the warranty period. The amount of our service revenues is typically a function of the 
number of post-warranty systems installed at our customers’ sites and the utilization of those systems, but it is also impacted 
by other factors, such as our rate of service contract renewals, the types of systems being serviced and fluctuations in foreign 
exchange rates. Service revenues increased sequentially over the fiscal years ended June 30, 2015, 2016 and 2017, primarily 
as a result of an increase over time in the number of post-warranty systems installed at our customers’ sites over that time 
period.

Gross margin 

Our  gross  margin  fluctuates  with  revenue  levels  and  product  mix  and  is  affected  by  variations  in  costs  related  to 
manufacturing and servicing our products, including our ability to scale our operations efficiently and effectively in response 
to prevailing business conditions.  

The following table summarizes the major factors that contributed to the changes in gross margin percentage:  

Fiscal year ended June 30, 2015 ............................................................................................................  
Revenue volume of products and services ................................................................................................  
Mix of products and services sold ............................................................................................................

Changes in gross margin percentage driven by revenue volume of products and services reflect our ability to leverage 
existing infrastructure to generate higher revenues. It also includes the effect of fluctuations in foreign exchange rates, average 
customer  pricing  and  customer  revenue  deferrals  associated  with  volume  purchase  agreements.  Changes  in  gross  margin 
percentage from mix of products and services sold reflect the impact of changes in the composition within product and service 
offerings.  Changes  in gross margin percentage  from  manufacturing  labor,  overhead  and  efficiencies  reflect  our  ability  to 
manage costs and drive productivity as we scale our manufacturing activity to respond to customer requirements; this includes 
the impact of capacity utilization, use of overtime and variability of cost structure. Changes in gross margin percentage from 
other service and manufacturing costs include the impact of customer support costs, including the efficiencies with which we 
deliver services to our customers, and the effectiveness with which we manage our production plans and inventory risk. 

Our gross margin increased to 63.0% during the fiscal year ended June 30, 2017 from 61.0% during the fiscal year 
ended June 30, 2016, primarily due to a higher revenue volume of products and services and a favorable mix of products and 
services sold, partially offset by other service and manufacturing costs. 

Our gross margin increased to 61.0% during the fiscal year ended June 30, 2016 from 56.8% during the fiscal year 
ended June 30, 2015, primarily due to a favorable mix of products and services sold, an increase in manufacturing efficiencies 
driven by lower warranty costs as well as a decrease in severance-related expenses, and higher revenue volume of products 
and services.

R&D expenses may fluctuate with product development phases and project timing as well as our focused R&D efforts 
that are aligned with our overall business strategy. As technological innovation is essential to our success, we may incur 
significant costs associated with R&D projects, including compensation for engineering talent, engineering material costs, 
and other expenses. 

R&D expenses during the fiscal year ended June 30, 2017 were higher compared to the fiscal year ended June 30, 2016, 
primarily due to an increase in employee-related expenses of $25.4 million as a result of additional engineering headcount, 
higher variable compensation, and higher employee benefit costs, an increase in consulting expenses of $12.5 million, an 
increase  in  engineering  materials  and  supplies  expenses  of  $9.9  million,  an  increase  in  merger-related  expenses  of  $2.3 
million, a lower benefit from external funding of $1.9 million and higher travel-related costs of $1.2 million, partially offset 
by a decrease in depreciation expense of $7.3 million and lower severance-related charges of $1.5 million. 

R&D expenses during the fiscal year ended June 30, 2016 were lower compared to the fiscal year ended June 30, 2015, 
primarily due to a decrease in employee-related expenses, including severance-related expenses of $33.9 million as a result 
of the reduced headcount from our global workforce reduction that we initiated during the three months ended June 30, 2015, 
partially offset by an increase in variable compensation of $10.6 million. Additionally, there was a decrease in engineering 
materials and supplies expenses of $21.0 million and an increase in the benefit to R&D expense from external funding of 
$5.4 million. 

Our future operating results will depend significantly on our ability to produce products and provide services that have 
a competitive advantage in our marketplace. To do this, we believe that we must continue to make substantial and focused 
investments  in  our  research  and  development.  We  remain  committed  to  product  development  in  new  and  emerging 
technologies as we address the yield challenges our customers face at future technology nodes.

SG&A expenses during the fiscal year ended June 30, 2017 were higher compared to the fiscal year ended June 30, 
2016, primarily due to an increase in consulting expenses of $7.1 million; an increase in employee-related expenses of $6.7 
million mainly as a result of higher variable compensation and employee benefit costs; an increase in travel costs of $2.3 
million; an increase in cost of support for sales evaluations of $1.3 million and an increase in facilities-related expense of 
$1.1 million. The increases above were partially offset by a decrease in merger-related expenses of $6.6 million and a lower 
severance-related charges of $3.7 million. 

SG&A expenses during the fiscal year ended June 30, 2016 were lower compared to the fiscal year ended June 30, 
2015, primarily due to a decrease in employee-related expenses, including severance-related expenses, of $28.0 million as a 
result of the reduced headcount from our global workforce reduction that we initiated during the three months ended June 30, 
2015  partially  offset  by  an  increase  in  variable  compensation  of  $16.4  million,  a  decrease  in  cost  of  support  for  sales 
evaluation of $8.6 million, a decrease in contributions to support our corporate social responsibility program of $7.0 million 
and a decrease in travel-related expenses of $4.7 million. The decreases above were partially offset by an increase in our 
merger-related  expenses  of  $15.6  million,  principally  for  financial  advisory  services  including  the  fairness  opinion  fees, 
employee-related expenses and legal fees during the fiscal year ended June 30, 2016.

Restructuring Charges 

During the fourth quarter of the fiscal year ended 2015, we announced a plan to reduce our global employee workforce 
to streamline our organization and business processes in response to changing customer requirements in its industry. The 
goals of this reduction were to enable continued innovation, direct our resources toward its best opportunities and lower our 
ongoing expense run rate. We substantially completed our global workforce reduction during the fiscal year ended June 30, 
2016.

During the fiscal year ended June 30, 2017 interest expense remained relatively unchanged compared to the fiscal year 

ended June 30, 2016. 

The increase in interest expense during the fiscal year ended June 30, 2016 compared to the fiscal year ended June 30, 
2015  was  primarily  attributable  to  the  $2.50  billion  aggregate  principal  amount  of  senior,  unsecured  long-term  notes 
(collectively  referred  to  as  “Senior  Notes”),  the  $750.0  million  unsecured  prepayable  term  loans  and  the  $500.0  million 
unfunded revolving credit facility which were executed during the three months ended December 31, 2014 and which were 
not outstanding for the entire fiscal year ended June 30, 2015. In addition, the $750.0 million of 2018 Senior Notes were 
redeemed during the three months ended December 31, 2014. 

Other expense (income), net is comprised primarily of realized gains or losses on sales of marketable securities, gains 
or losses from revaluations of certain foreign currency denominated assets and liabilities as well as foreign currency contracts, 
impairments associated with equity investments in privately-held companies, interest related accruals (such as interest and 
penalty accruals related to our tax obligations) and interest income earned on our investment and cash portfolio.  

The decrease in other expense (income), net during the fiscal year ended June 30, 2017 compared to the fiscal year 
ended June 30, 2016 was primarily due to an increase in interest accruals related to uncertain tax positions of $6.4 million, a 
decrease in net gains from our investments in privately-held companies of $3.6 million, partially offset by an increase in 
interest income of $8.8 million. 

The increase in other expense (income), net during the fiscal year ended June 30, 2016 compared to the fiscal year 
ended June 30, 2015 was primarily due to reduction of interest and penalty accruals related to uncertain tax positions of $5.5 
million  and  an  increase  of  $4.5  million  for  gain  on  the  sale  of  equity  investments  in  privately-held  companies  net  of 
impairment charges.

Loss on extinguishment of debt and other, net 

For the fiscal year ended June 30, 2015, loss on extinguishment of debt and other, net, reflected a pre-tax net loss of 
$131.7 million associated with the redemption of our $750.0 million of 2018 Senior Notes during the three months ended 
December  31,  2014.  Included  in  the  loss  on  extinguishment  of  debt  and  other,  net  is  the  $1.2  million  gain  on  the  non-
designated forward contract that was entered into by us in anticipation of the redemption of the 2018 Senior Notes, which 
were  redeemed  during  the  three  months  ended  December  31,  2014.  Refer  to  “Note  7,  Debt”  and  “Note  16,  Derivative 
Instruments  and  Hedging  Activities”  to  the  consolidated  financial  statements  for  further  details.  We  had  no  loss  on 
extinguishment of debt and other, net, in the fiscal years ended June 30, 2017 and 2016.

The provision for income taxes differs from the statutory U.S. federal rate primarily due to foreign income with lower 

tax rates, tax credits, and other domestic incentives.  

Tax expense as a percentage of income during the fiscal year ended June 30, 2017 was 21.1% compared to 17.9% for 
the fiscal year ended June 30, 2016. Tax expense as a percentage of income increased primarily due to an increase in the 
percentage of income earned in the U.S. compared to income earned outside the U.S. in jurisdictions with lower tax rates. 
Tax expense as a percentage of income increased also because there was a decrease in unrecognized tax benefits during the 
fiscal year ended June 30, 2016 compared to the fiscal year ended June 30, 2017 due to settlements with taxing authorities 
and expiration of statutes of limitations. 

Tax expense as a percentage of income during the fiscal year ended June 30, 2016 was 17.9% compared to 15.7% for 
the fiscal year ended June 30, 2015. Tax expense as a percentage of income increased primarily due to an increase in the 
percentage of income earned in the U.S. compared to income earned outside the U.S. in jurisdictions with lower tax rates. 
During the fiscal year ended June 30, 2015, the loss on extinguishment of debt decreased income earned in the U.S. 

Our future effective income tax rate depends on various factors, such as tax legislation, the geographic composition of 
our pre-tax income, the amount of our pre-tax income as business activities fluctuate, non-deductible expenses incurred in 
connection with acquisitions, research and development credits as a percentage of aggregate pre-tax income, the domestic 
manufacturing  deduction,  non-taxable  or  non-deductible  increases  or  decreases  in  the  assets  held  within  our  Executive 
Deferred Savings Plan, the tax effects of employee stock activity and the effectiveness of our tax planning strategies. 

In the normal course of business, we are subject to tax audits in various jurisdictions, and such jurisdictions may assess 
additional income or other taxes against us. We are under income tax examination in Israel for the fiscal years ended June 
30, 2013 through June 30, 2015. Although we believe our tax estimates are reasonable, the final determination of tax audits 
and any related litigation could be materially different from our historical income tax provisions and accruals. The results of 
an audit or litigation could have a material adverse effect on our results of operations or cash flows in the period or periods 
for which that determination is made.

Cash and Cash Equivalents and Marketable Securities: 

As of June 30, 2017, our cash, cash equivalents and marketable securities totaled $3.02 billion, which is an increase of 
$525.4 million from June 30, 2016. The increase is primarily attributable to our cash generated from operations, partially 
offset by net purchases of marketable securities of $493.2 million, payment of dividends of $344.0 million, payment of term 
loans of $130.0 million, cash used for a business acquisition of $28.6 million and payment for stock repurchases of $25.0 
million. As of June 30, 2017, $2.16 billion of our $3.02 billion of cash, cash equivalents, and marketable securities were held 
by our foreign subsidiaries and branch offices. We currently intend to indefinitely reinvest $2.00 billion of the cash, cash 
equivalents  and  marketable  securities  held  by  our  foreign  subsidiaries.  If,  however,  a  portion  of  these  funds  were  to  be 
repatriated to the United States, we would be required to accrue and pay U.S. and foreign taxes of approximately 30%-50% 
of the funds repatriated. The amount of taxes due will depend on the amount and manner of the repatriation, as well as the 
location from which the funds are repatriated. Of the $2.16 billion, the remaining cash of $156.4 million is held by our foreign 
subsidiaries and branches for which earnings are not indefinitely reinvested. As we have accrued (but not paid) U.S. taxes on 
the earnings of these subsidiaries and branches, these funds can be returned to the U.S. without accruing any additional U.S. 
tax expense.  

Cash Dividends and Special Cash Dividend: 

The total amount of regular quarterly cash dividends paid during the fiscal years ended June 30, 2017, 2016 and 2015 
was $335.4 million, $324.5 million and $324.8 million, respectively. The increase in the amount of regular quarterly cash 
dividends paid during the fiscal year ended June 30, 2017 reflected the increase in the level of our regular quarterly cash 
dividend from $0.52 to $0.54 per share that was instituted during the three months ended December 31, 2016. The amount of 
accrued dividends payable for regular quarterly cash dividends on unvested restricted stock units with dividend equivalent 
rights was $4.8 million and $2.7 million as of June 30, 2017 and 2016, respectively. These amounts will be paid upon vesting 
of the underlying unvested restricted stock units as described in Note 8, “Equity and Long-term Incentive Compensation 
Plans.” 

On June 1, 2017, we announced that our Board of Directors had authorized an increase in the level of our quarterly 
cash dividend from $0.54 to $0.59 per share. Refer to Note 19, “Subsequent Events” to the consolidated financial statements 
for additional information regarding the declaration of our quarterly cash dividend announced subsequent to June 30, 2017.

On November 19, 2014, we declared a special cash dividend of $16.50 per share on our outstanding common stock 
which  was  paid  on  December  9,  2014  to  our  stockholders  of  record  as  of  the  close  of  business  on  December  1,  2014. 
Additionally, in connection with the special cash dividend, our Board of Directors and our Compensation Committee of our 
Board of Directors approved a proportionate and equitable adjustment to outstanding equity awards (restricted stock units 
and stock options) under the 2004 Equity Incentive Plan (the “2004 Plan”), as required by the 2004 Plan, subject to the vesting 
requirements of the underlying awards. As the adjustment was required by the 2004 Plan, the adjustment to the outstanding 
awards did not result in any incremental compensation expense due to modification of such awards, under the authoritative 
guidance. The declaration and payment of the special cash dividend was part of our leveraged recapitalization transaction 
under  which  the  special  cash  dividend  was  financed  through  a  combination  of  existing  cash  and  proceeds  from  the  debt 
financing  disclosed  in Note 7,  “Debt”  that was  completed during  the  three  months  ended  December 31,  2014.  As of  the 
declaration date, the total amount of the special cash dividend accrued by us was approximately $2.76 billion, substantially 
all of which was paid out during the three months ended December 31, 2014, except for the aggregate special cash dividend 
of $43.0 million that was accrued for the unvested restricted stock units. As of June 30, 2017 and 2016, we had $9.0 million 
and  $16.9  million,  respectively,  of  accrued  dividends  payable  for  the  special  cash  dividend  with  respect  to  outstanding 
unvested  restricted  stock units,  which will  be  paid when such  underlying  unvested  restricted  stock  units  vest. We paid a 
special cash dividend with respect to vested restricted stock units during the fiscal years ended June 30, 2017, 2016 and 2015 
of $8.6 million, $21.8 million and $1.8 million, respectively. Other than the special cash dividend declared during the three 
months ended December 31, 2014, we historically have not declared any special cash dividend. 

Stock Repurchases: 

The  shares  repurchased  under  our  stock  repurchase  program  have  reduced  our  basic  and  diluted  weighted-average 
shares outstanding for the fiscal years ended June 30, 2017 and 2016. The stock repurchase program is intended, in part, to 
offset shares issued in connection with the purchases under our ESPP program and the vesting of employee restricted stock 
units.  

Fiscal Year 2017 Compared to Fiscal Year 2016 

Cash Flows from Operating Activities: 

We have historically financed our liquidity requirements through cash generated from operations. Net cash provided 
by operating activities during the fiscal year ended June 30, 2017 increased compared to the fiscal year ended June 30, 2016, 
from $759.7 million to $1.08 billion primarily as a result of the following key factors: 

• 

• 

• 

An increase in collections of approximately $567.0 million during the fiscal year ended June 30, 2017 compared
to the fiscal year June 30, 2016, mainly driven by higher shipments; 

The positive impact of our early adoption of the new accounting standard update for share-based payment awards 
to employees on a prospective basis during the fiscal year ended June 30, 2017, which no longer requires the
excess tax benefit from share-based compensation to be shown as a reduction within cash flows from operating
activities of $11.9 million compared to the fiscal ended June 30, 2016; 

An increase in interest income of approximately $9.0 million during the fiscal year ended June 30, 2017 compared 
to the fiscal year ended June 30, 2016, as U.S. dollar interest rates increased; partially offset by 

◦ 

◦ 

An increase in accounts payable payments of approximately $71.0 million during the fiscal year ended June
30, 2017 compared to the fiscal year ended June 30, 2016; 

An increase in income tax payments of $129.0 million during the fiscal year ended June 30, 2017 compared
to the fiscal year ended June 30, 2016, reflecting higher operating profits; 

54 

 
 
 
 
 
 
 
 
 
 
 
 
 
◦ 

◦ 

An increase in payroll and employee expenses of approximately $85.0 million during the fiscal year ended
June 30, 2017 compared to the fiscal year ended June 30, 2016, primarily due to a change in the timing of
certain variable compensation payments; and 

Less unfavorable impacts from currency fluctuations of approximately $19.0 million during the fiscal year
ended June 30, 2017 compared to the fiscal year ended June 30, 2016. 

Cash Flows from Investing Activities: 

Net cash used by investing activities during the fiscal year ended June 30, 2017 was $560.9 million compared to net 
cash provided by investing activities of $144.7 million during the fiscal year ended June 30, 2016. The change primarily 
resulted  from  net  purchases of  marketable securities  of $493.2  million and cash used for  a business acquisition  of $28.6 
million during the fiscal year ended June 30, 2017. 

Cash Flows from Financing Activities: 

Net cash used in financing activities during the fiscal year ended June 30, 2017 decreased compared to the fiscal year 
ended June 30, 2016, from $636.7 million to $472.8 million, primarily as a result of a decrease in common stock repurchases 
of $156.7 million and the impact of our early adoption of the new accounting standard update for share-based payment awards 
to employees on a prospective basis during the year ended June 30, 2017. This new standard no longer requires the excess 
tax benefit from share-based compensation to be shown as a cash inflow from financing activities, resulting in a change of 
$11.9 million from the year ended June 30, 2016. 

Fiscal Year 2016 Compared to Fiscal Year 2015 

Cash Flows from Operating Activities: 

Net cash provided by operating activities during the fiscal year ended June 30, 2016 increased compared to the fiscal 

year ended June 30, 2015, from $605.9 million to $759.7 million primarily as a result of the following key factors: 

• 

• 

An increase in collections of approximately $294.0 million mostly due to higher shipments during the fiscal year
ended June 30, 2016 compared to the fiscal year ended June 30, 2015; 

A decrease in payroll and employee-related payments of approximately $34.0 million during the fiscal year ended
June 30, 2016 compared to the fiscal year ended June 30, 2015; partially offset by 

◦ 

◦ 

◦ 

An increase in vendor payments of approximately $65.0 million during the fiscal year ended June 30, 2016 
mainly due to higher inventory purchases compared to the fiscal year ended June 30, 2015; 

A net increase of realized foreign exchange hedge losses of approximately $48.0 million during the fiscal
year ended June 30, 2016 compared to the fiscal year ended June 30, 2015, mainly due to the substantial
foreign exchange fluctuations in Japanese Yen during these periods; 

An increase in debt interest payments of approximately $27.0 million during the fiscal year ended June
30, 2016 due to higher average outstanding debt balances compared to the fiscal year ended June 30, 2015; 

55 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
◦ 

◦ 

An increase in income tax and other tax payments net of tax refunds of approximately $22.0 million during
the fiscal year ended June 30, 2016 compared to the fiscal year ended June 30, 2015; and 

An  increase  in  cash  LTI  payments  of  approximately  $13.0  million  during  the  fiscal  year  ended  June 
30, 2016 compared to the fiscal year ended June 30, 2015. 

Cash Flows from Investing Activities: 

Net  cash  provided  by  investing  activities  during  the  fiscal  year  ended  June  30,  2016  decreased  to  $144.7  million 
compared to the fiscal year ended June 30, 2015 from net cash provided in investing activities of $918.2 million, primarily 
as a result of our strategic decision to liquidate certain marketable securities in our investment portfolio to fund our working 
capital requirements during the fiscal year ended June 30, 2015, partially offset by approximately $14.0 million lower capital 
expenditures during the fiscal year ended June 30, 2016, as compared to the fiscal year ended June 30, 2015. 

Cash Flows from Financing Activities: 

Net cash used in financing activities during the fiscal year ended June 30, 2016 decreased compared to the fiscal year 

ended June 30, 2015, from $1.30 billion to $636.7 million, primarily as a result of the following key factors: 

• 

• 

• 

A decrease in payment of dividends to stockholders of $2.70 billion, primarily from the payment of special cash
dividend during the fiscal year ended June 30, 2015; 

A decrease in repayment of debt of approximately $781.0 million mainly as a result of the redemption of the 2018
Senior Notes during the fiscal year ended June 30, 2015; 

A decrease in common stock repurchases of $421.0 million during the fiscal year ended June 30, 2016 compared 
to the fiscal year ended June 30, 2015. In connection with entering into the Merger Agreement, we suspended 
further repurchases under our repurchase program effective October 21, 2015; partially offset by 

◦ 

Net proceeds of $3.22 billion from the issuance of Senior Notes and the term loans during the fiscal year
ended June 30, 2015. 

Senior Notes: 

In  November  2014,  we  issued  $2.50  billion  aggregate  principal  amount  of  senior,  unsecured  long-term  notes 
(collectively referred to as “Senior Notes”). We issued the Senior Notes as part of the leveraged recapitalization plan under 
which the proceeds from the Senior Notes in conjunction with the proceeds from the term loans (described below) and cash 
on hand were used (x) to fund a special cash dividend of $16.50 per share, aggregating to approximately $2.76 billion, (y) to 
redeem $750.0 million of 2018 Senior Notes, including associated redemption premiums, accrued interest and other fees and 
expenses  and  (z)  for  other  general  corporate  purposes,  including  repurchases  of  shares  pursuant  to  our  stock  repurchase 
program. The interest rate specified for each series of the Senior Notes will be subject to adjustments from time to time if 
Moody’s Investor Service, Inc. (“Moody’s”) or Standard & Poor’s Ratings Services (“S&P”) or, under certain circumstances, 
a substitute rating agency selected by us as a replacement for Moody’s or S&P, as the case may be (a “Substitute Rating 
Agency”), downgrades (or subsequently upgrades) its rating assigned to the respective series of Senior Notes such that the 
adjusted rating is below investment grade. If the adjusted rating of any series of Senior Notes from Moody’s (or, if applicable, 
any Substitute Rating Agency) is decreased to Ba1, Ba2, Ba3 or B1 or below, the stated interest rate on such series of Senior 
Notes as noted above will increase by 25 bps, 50 bps, 75 bps or 100 bps, respectively (“bps” refers to Basis Points and 1% is 
equal to 100 bps). If the rating of any series of Senior Notes from S&P (or, if applicable, any Substitute Rating Agency) with 
respect to such series of Senior Notes is decreased to BB+, BB, BB- or B+ or below, the stated interest rate on such series of 
Senior Notes as noted above will increase by 25 bps, 50 bps, 75 bps or 100 bps, respectively. The interest rates on any series 

56 

 
 
 
 
 
 
 
 
  
 
  
 
  
of Senior Notes will permanently cease to be subject to any adjustment (notwithstanding any subsequent decrease in the 
ratings by any of Moody’s, S&P and, if applicable, any Substitute Rating Agency) if such series of Senior Notes becomes 
rated “Baa1” (or its equivalent) or higher by Moody’s (or, if applicable, any Substitute Rating Agency) and “BBB+” (or its 
equivalent) or higher by S&P (or, if applicable, any Substitute Rating Agency), or one of those ratings if rated by only one 
of Moody’s, S&P and, if applicable, any Substitute Rating Agency, in each case with a stable or positive outlook. In October 
2014, we entered into a series of forward contracts to lock the 10-year treasury rate (“benchmark rate”) on a portion of the 
Senior  Notes  with  a  notional  amount  of  $1.00  billion  in  aggregate.  For  additional  details,  refer  to  Note  16,  “Derivative 
Instruments and Hedging Activities” to the consolidated financial statements. 

The original discount on the Senior Notes amounted to $4.0 million and is being amortized over the life of the debt. 
Interest is payable semi-annually on May 1 and November 1 of each year. The debt indenture (the “Indenture”) includes 
covenants that limit our ability to grant liens on its facilities and enter into sale and leaseback transactions, subject to certain 
allowances under which certain sale and leaseback transactions are not restricted. As of June 30, 2017, we were in compliance 
with all of the covenants under the Indenture associated with the Senior Notes. 

Credit Facility (Term Loans and Unfunded Revolving Credit Facility): 

In November 2014, we entered into $750.0 million of five-year senior unsecured prepayable term loans and a $500.0 
million  unfunded  revolving  credit  facility  (collectively,  the  “Credit  Facility”)  under  the  Credit  Agreement  (the  “Credit 
Agreement”). The interest under the Credit Facility will be payable on the borrowed amounts at the London Interbank Offered 
Rate (“LIBOR”) plus a spread, which is currently 125 bps, and this spread is subject to adjustment in conjunction with our 
credit rating downgrades or upgrades. The spread ranges from 100 bps to 175 bps based on the then effective credit rating. 
We are also obligated to pay an annual commitment fee of 15 bps on the daily undrawn balance of the revolving credit facility, 
which is also subject to an adjustment in conjunction with our credit rating downgrades or upgrades by Moody’s and S&P. 
The  annual  commitment  fee  ranges from  10 bps  to 25  bps  on  the daily  undrawn balance  of  the revolving  credit  facility, 
depending upon the then effective credit rating. Principal payments with respect to the term loans will be made on the last 
day of each calendar quarter and any unpaid principal balance of the term loans, including accrued interest, shall be payable 
on November 14, 2019 (the “Maturity Date”). We may prepay the term loans and unfunded revolving credit facility at any 
time without a prepayment penalty. During the fiscal year ended June 30, 2017, we made term loan principal payments of 
$130.0 million. The remaining term loan balance of $446.3 million as of June 30, 2017 is due in the fiscal quarter ending 
December 31, 2019. 

The Credit Facility requires us to maintain an interest expense coverage ratio as described in the Credit Agreement, on 
a quarterly basis, covering the trailing four consecutive fiscal quarters of no less than 3.50 to 1.00. In addition, we are required 
to maintain the maximum leverage ratio as described in the Credit Agreement on a quarterly basis of 3.00 to 1.00, covering 
the trailing four consecutive fiscal quarters for each fiscal quarter. 

We  were  in  compliance  with  the  financial  covenants  under  the  Credit  Agreement  as  of  June  30, 2017 (the  interest 
expense coverage ratio was 11.58 to 1.00 and the leverage ratio was 2.08 to 1.00) and had no outstanding borrowings under 
the unfunded revolving credit facility. Considering our current liquidity position, short-term financial forecasts and ability to 
prepay the term loans, if necessary, we expect to continue to be in compliance with our financial covenants at the end of our 
first quarter of fiscal year ending June 30, 2018. 

Debt Redemption:  

In December 2014, we redeemed the $750.0 million aggregate principal amount of 2018 Senior Notes. The redemption 
resulted in a pre-tax net loss on extinguishment of debt of $131.7 million for the three months ended December 31, 2014, 
after an offset of a $1.2 million of gain upon the termination of the non-designated forward contract described below. 

In addition, in November 2014, we entered into a non-designated forward contract to lock the treasury rate to be used 
for determining the redemption amount as part of our plan to redeem the existing 2018 Senior Notes. The notional amount of 

57 

 
the non-designated forward contract was $750.0 million. For additional details, refer to Note 16, “Derivative Instruments and 
Hedging Activities” to the consolidated financial statements.

__________________   

(1)  In  November  2014,  we  issued  $750.0  million  aggregate  principal  amount  of  term  loans  due  in  fiscal  year  2020
(outstanding balance of $446.3 million as of June 30, 2017) and $2.50 billion aggregate principal amount of Senior Notes
due from fiscal year 2018 to fiscal year 2035. During our fiscal year ended June 30, 2017, we made term loan principal
payments of $130.0 million. 

(2)  The interest payments associated with the Senior Notes obligations included in the table above are based on the principal
amount multiplied by the applicable coupon rate for each series of Senior Notes. Our future interest payments are subject
to change if our then effective credit rating is below investment grade as discussed above. The interest payments under
the term loans are payable on the borrowed amounts at the LIBOR plus 125 bps. As of June 30, 2017, we utilized the 
existing interest rates to project our estimated term loans interest payments for the next five years. The interest payment
under the revolving credit facility for the undrawn balance is payable at 15 bps as a commitment fee based on the daily
undrawn balance and we utilized the existing rate for the projected interest payments included in the table above. Our
future interest payments for the term loans and the revolving credit facility are subject to change due to future fluctuations 
in the LIBOR rates as well as any upgrades or downgrades to our then effective credit rating. 

(3)  Represents an estimate of significant commitments to purchase inventory from our suppliers as well as an estimate of
significant  purchase  commitments  associated  with  other  goods  and  services  in  the  ordinary  course  of  business.  Our
liability under these purchase commitments is generally restricted to a forecasted time-horizon as mutually agreed upon
between  the  parties.  This  forecasted  time-horizon  can  vary  among  different  suppliers.  Actual  expenditures  will  vary
based upon the volume of the transactions and length of contractual service provided. In addition, the amounts paid under

58 

 
   
   
       
       
       
       
       
       
       
 
  
  
  
  
  
  
  
 
 
 
 
 
 
these arrangements may be less in the event the arrangements are renegotiated or canceled. Certain agreements provide
for potential cancellation penalties. 

(4)  Represents  the  estimated  income  tax  payable  obligation  related  to  uncertain  tax  positions  as  well  as  related  accrued
interest.  We  are  unable  to  make  a  reasonably  reliable  estimate  of  the  timing  of  payments  in  individual  years  due  to
uncertainties in the timing of tax audit outcomes. 

(5)  Represents the amount committed under our cash long-term incentive program. The expected payment after estimated

forfeitures is approximately $133.0 million. 

(6)  Represents an estimate of expected benefit payments up to fiscal year 2027 that was actuarially determined and excludes
the minimum cash required to contribute to the plan. As of June 30, 2017, our defined pension plans do not have material
required minimum cash contribution obligations. 

(7)  Represents the amount committed under our non-qualified executive deferred compensation plan. We are unable to make
a reasonably reliable estimate of the timing of payments in individual years due to the uncertainties in the timing around
participant’s  separation  and  any  potential  changes  that  participants  may  decide  to  make  to  the  previous  distribution
elections. 

(8)  Includes $20.8 million of employee-related retention commitments in connection with the retention program adopted at
the  time  we  entered  into  the  Merger  Agreement  with  Lam  Research  as  well  as  the  amount  committed  for  accrued
dividends payable of $13.8 million, substantially all of which are for the special cash dividend for the unvested restricted
stock units as of the dividend record date as well as quarterly cash dividends from unvested restricted stock units granted
with dividend equivalent rights. For additional details, refer to Note 8, “Equity and Long-term Incentive Compensation 
Plans.” 

We have adopted a cash-based long-term incentive (“Cash LTI”) program for many of our employees as part of our 
employee compensation program. Cash LTI awards issued to employees under the Cash Long-Term Incentive Plan (“Cash 
LTI Plan”) generally vest in three or four equal installments, with one-third or one-fourth of the aggregate amount of the 
Cash LTI award vesting on each yearly anniversary of the grant date over a three or four-year period. In order to receive 
payments under the Cash LTI Plan, participants must remain employed by us as of the applicable award vesting date.  

We  have  agreements  with  financial  institutions  to  sell  certain  of  our  trade  receivables  and  promissory  notes  from 
customers without recourse. In addition, we periodically sell certain letters of credit (“LCs”), without recourse, received from 
customers in payment for goods and services. 

The following table shows total receivables sold under factoring agreements and proceeds from sales of LCs for the 

indicated periods:

We maintain guarantee arrangements available through various financial institutions for up to $25.3 million, of which 
$22.1 million had been issued as of June 30, 2017, primarily to fund guarantees to customs authorities for value-added tax 
(“VAT”) and other operating requirements of our subsidiaries in Europe and Asia.

We  maintain  certain  open  inventory  purchase  commitments  with  our  suppliers  to  ensure  a  smooth  and  continuous 
supply  for  key  components.  Our  liability  under  these  purchase  commitments  is  generally  restricted  to  a  forecasted  time-
horizon as mutually agreed upon between the parties. This forecasted time-horizon can vary among different suppliers. Our 
open inventory purchase commitments were approximately $432.8 million as of June 30, 2017 and are primarily due within 
the next 12 months. Actual expenditures will vary based upon the volume of the transactions and length of contractual service 
provided.  In  addition,  the  amounts  paid  under  these  arrangements  may  be  less  in  the  event  that  the  arrangements  are 
renegotiated or canceled. Certain agreements provide for potential cancellation penalties. 

We provide standard warranty coverage on our systems for 40 hours per week for 12 months, providing labor and parts 
necessary to repair and maintain the systems during the warranty period. We account for the estimated warranty cost as a 
charge  to  costs  of  revenues  when  revenue  is  recognized.  The  estimated  warranty  cost  is  based  on  historical  product 
performance and field expenses. The actual product performance and/or field expense profiles may differ, and in those cases 
we adjust our warranty accruals accordingly. The difference between the estimated and actual warranty costs tends to be 
larger for new product introductions as there is limited historical product performance to estimate warranty expense; our 
warranty charge estimates for more mature products with longer product performance histories tend to be more stable. Non-
standard  warranty  coverage  generally  includes  services  incremental  to  the  standard  40-hours  per  week  coverage  for  12 
months. See Note 13, “Commitments and Contingencies” to the Consolidated Financial Statements for additional details. 

Working Capital: 

Working  capital  was  $3.10  billion  as  of  June  30,  2017,  which  was  an  increase  of  $233.3  million  compared  to  our 
working capital as of June 30, 2016. As of June 30, 2017, our principal sources of liquidity consisted of $3.02 billion of cash, 
cash equivalents and marketable securities. Our liquidity is affected by many factors, some of which are based on the normal 
ongoing operations of the business, and others of which relate to the uncertainties of global and regional economies and the 
semiconductor and the semiconductor equipment industries. Although cash requirements will fluctuate based on the timing 
and extent of these factors, we believe that cash generated from operations, together with the liquidity provided by existing 
cash and cash equivalents balances and our $500.0 million unfunded revolving credit facility, will be sufficient to satisfy our 
liquidity requirements associated with working capital needs, capital expenditures, dividends, stock repurchases and other 
contractual obligations, including repayment of outstanding debt, for at least the next 12 months.  

Our credit ratings as of June 30, 2017 are summarized below:

Off-Balance Sheet Arrangements 

Under our foreign currency risk management strategy, we utilize derivative instruments to protect our earnings and 
cash flows from unanticipated fluctuations in earnings and cash flows caused by volatility in currency exchange rates. This 
financial exposure is monitored and managed as an integral part of our overall risk management program, which focuses on 
the unpredictability of financial markets and seeks to reduce the potentially adverse effects that the volatility of these markets 
may have on our operating results. We continue our policy of hedging our current and forecasted foreign currency exposures 
with hedging instruments having tenors of up to 18 months (see Note 16, “Derivative Instruments and Hedging Activities” 
to the Consolidated Financial Statements for additional details). Our outstanding hedge contracts, with maximum remaining 
maturities of approximately ten months and seven months as of June 30, 2017 and 2016, respectively, were as follows:

In October 2014, in anticipation of the issuance of the Senior Notes, we entered into a series of forward contracts (“Rate 
Lock Agreements”) to lock the benchmark rate on a portion of the Senior Notes. The objective of the Rate Lock Agreements 
was to hedge the risk associated with the variability in interest rates due to the changes in the benchmark rate leading up to 
the closing of the intended financing, on the notional amount being hedged. The Rate Lock Agreements had a notional amount 
of $1.00 billion in aggregate which matured in the second quarter of the fiscal year ended June 30, 2015. We designated each 
of the Rate Lock Agreements as a qualifying hedging instrument and accounted for as a cash flow hedge, under which the 
effective portion of the gain or loss on the close out of the Rate Lock Agreements was initially recognized in accumulated 
other comprehensive income (loss) as a reduction of total stockholders’ equity and subsequently amortized into earnings as 
a component of interest expense over the term of the underlying debt. The ineffective portion, if any, was recognized in 
earnings immediately. The Rate Lock Agreements were terminated on the date of pricing of the $1.25 billion of 4.650% 
Senior Notes due in 2024 and we recorded the fair value of $7.5 million as a gain within accumulated other comprehensive 
income (loss) as of December 31, 2014. For the fiscal years ended June 30, 2017, 2016 and 2015, we recognized $0.8 million, 
$0.8 million and $0.5 million, respectively, for the amortization of the gain recognized in accumulated other comprehensive 
income (loss), which amount reduced the interest expense. As of June 30, 2017, the unamortized portion of the fair value of 
the forward contracts for the rate lock agreements was $5.5 million. The cash proceeds of $7.5 million from the settlement 
of the Rate Lock Agreements were included in the cash flows from operating activities in the consolidated statements of cash 
flows for the fiscal year ended June 30, 2015 because the designated hedged item was classified as interest expense in the 
cash flows from operating activities in the consolidated statements of cash flows. 

In addition, in November 2014, we entered into a non-designated forward contract to lock the treasury rate used to 
determine the redemption amount of the 2018 Senior Notes that occurred during the three months ended December 31, 2014. 
The objective of the forward contract was to hedge the risk associated with the variability of the redemption amount due to 
changes  in  interest  rates  through  the  redemption  of  the  existing  2018  Senior  Notes.  The  forward  contract  had  a  notional 
amount of $750.0 million. The forward contract was terminated in December 2014 and the resulting fair value of $1.2 million 
was included in the loss on extinguishment of debt and other, net line in the consolidated statements of operations, partially 
offsetting the loss on redemption of the debt during the three months ended December 31, 2014. The cash proceeds from the 
forward contract were included in the cash flows from financing activities in the consolidated statements of cash flows for 
the fiscal year ended June 30, 2015, partially offsetting the cash outflows for the redemption of the 2018 Senior Notes.

Indemnification  Obligations.  Subject  to  certain  limitations,  we  are  obligated  to  indemnify  our  current  and  former 
directors, officers and employees with respect to certain litigation matters and investigations that arise in connection with 
their service to us. These obligations arise under the terms of our certificate of incorporation, our bylaws, applicable contracts, 
and Delaware and California law. The obligation to indemnify generally means that we are required to pay or reimburse the 
individuals’ reasonable legal expenses and possibly damages and other liabilities incurred in connection with these matters. 
For example, we have paid or reimbursed legal expenses incurred in connection with the investigation of our historical stock 
option practices and the related litigation and government inquiries by a number of our current and former directors, officers 
and  employees.  Although  the  maximum  potential  amount  of  future  payments  we  could  be  required  to  make  under  the 
indemnification obligations generally described in this paragraph is theoretically unlimited, we believe the fair value of this 
liability, to the extent estimable, is appropriately considered within the reserve we have established for currently pending 
legal proceedings. 

We are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party with 
respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale 
of assets, under which we customarily agree to hold the other party harmless against losses arising from, or provide customers 
with other remedies to protect against, bodily injury or damage to personal property caused by our products, non-compliance 
with our product performance specifications, infringement by our products of third-party intellectual property rights and a 
breach of warranties, representations and covenants related to matters such as title to assets sold, validity of certain intellectual 
property rights, non-infringement of third-party rights, and certain income tax-related matters. In each of these circumstances, 
payment by us is typically subject to the other party making a claim to and cooperating with us pursuant to the procedures 
specified  in  the  particular  contract.  This  usually  allows  us  to  challenge  the  other  party’s  claims  or,  in  case  of  breach  of 
intellectual  property  representations  or  covenants,  to  control  the  defense  or  settlement  of  any  third-party  claims  brought 
against the other party. Further, our obligations under these agreements may be limited in terms of amounts, activity (typically 
at our option to replace or correct the products or terminate the agreement with a refund to the other party), and duration. In 
some instances, we may have recourse against third parties and/or insurance covering certain payments made by us. 

In addition, we may in limited circumstances enter into agreements that contain customer-specific commitments on 
pricing, tool reliability, spare parts stocking levels, service response time and other commitments. Furthermore, we may give 
these customers limited audit or inspection rights to enable them to confirm that we are complying with these commitments. 
If a customer elects to exercise its audit or inspection rights, we may be required to expend significant resources to support 
the audit or inspection, as well as to defend or settle any dispute with a customer that could potentially arise out of such audit 
or inspection. To date, we have made no significant accruals in our consolidated financial statements for this contingency. 
While we have not in the past incurred significant expenses for resolving disputes regarding these types of commitments, we 
cannot make any assurance that we will not incur any such liabilities in the future. 

It is not possible to predict the maximum potential amount of future payments under these or similar agreements due 
to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. 
Historically, payments made by us under these agreements have not had a material effect on our business, financial condition, 
results of operations or cash flows.

ITEM  7A. 

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

We  are  exposed  to  financial  market  risks,  including  changes  in  interest  rates,  foreign  currency  exchange  rates  and 
marketable equity security prices. To mitigate these risks, we utilize derivative financial instruments, such as foreign currency 
hedges. All of the potential changes noted below are based on sensitivity analyses performed on our financial position as of 
June 30, 2017. Actual results may differ materially. 

As of June 30, 2017, we had an investment portfolio of fixed income securities of $2.10 billion. These securities, as 
with all fixed income instruments, are subject to interest rate risk and will decline in value if market interest rates increase. If 
market interest rates were to increase immediately and uniformly by 100 bps from levels as of June 30, 2017, the fair value 
of the portfolio would have declined by $21.9 million. 

In November 2014, we issued $2.50 billion aggregate principal amount of fixed rate senior, unsecured long-term notes 
(collectively referred to as “Senior Notes”) due in various fiscal years ranging from 2018 to 2035. The fair market value of 
long-term fixed interest rate notes is subject to interest rate risk. Generally, the fair market value of fixed interest rate notes 
will increase as interest rates fall and decrease as interest rates rise. As of June 30, 2017, the fair value and the book value of 
our Senior Notes were $2.67 billion and $2.50 billion, respectively. Additionally, the interest expense for the Senior Notes is 
subject to interest rate adjustments following a downgrade of our credit ratings below investment grade by the credit rating 
agencies. Following a rating change below investment grade, the stated interest rate for each series of Senior Notes may 
increase between 25 bps to 100 bps based on the adjusted credit rating. Refer to Note 7, “Debt” to the Consolidated Financial 
Statements in Part II, Item 8 and Management’s Discussion and Analysis of Financial Condition and Results of Operations, 
“Liquidity and Capital Resources,” in Part II, Item 7 for additional details. Factors that can affect our credit ratings include 
changes  in  our  operating  performance,  the  economic  environment,  conditions  in  the  semiconductor  and  semiconductor 
equipment industries, our financial position, and changes in our business strategy. As of June 30, 2017, if our credit rating 
was  downgraded  below  investment  grade  by  Moody’s  and  S&P,  the  maximum  potential  increase  to  our  annual  interest 
expense on the Senior Notes, considering a 200 bps increase to the stated interest rate for each series of our Senior Notes, is 
estimated to be approximately $46.7 million. 

In  November  2014,  we  entered  into  $750.0  million  aggregate  principal  amount  of  floating  rate  senior,  unsecured 
prepayable term loans due in 2019 and a $500.0 million unfunded revolving credit facility. The interest rates for the term 
loans are based on LIBOR plus a fixed spread and this spread is subject to adjustment in conjunction with our credit rating 
downgrades or upgrades. The spread ranges from 100 bps to 175 bps based on the adjusted credit rating. The fair value of the 
term loans is subject to interest rate risk only to the extent of the fixed spread portion of the interest rates which does not 
fluctuate with change in interest rates. As of June 30, 2017, the difference between book value and fair value of our term 
loans was immaterial. We are also obligated to pay an annual commitment fee of 15 bps on the daily undrawn balance of the 
unfunded revolving credit facility which is also subject to an adjustment in conjunction with our credit rating downgrades or 
upgrades. The annual commitment fee ranges from 10 bps to 25 bps on the daily undrawn balance of the revolving credit 
facility, depending upon the then effective credit rating. As of June 30, 2017, if LIBOR-based interest rates increased by 100 
bps,  the  change  would  increase  our  annual  interest  expense  annually  by  approximately  $4.0  million  as  it  relates  to  our 
borrowings  under  the  term  loans.  Additionally,  as  of  June  30,  2017,  if  our  credit  rating  was  downgraded  to  be  below 
investment grade, the maximum potential increase to our annual interest expense for the term loans and the revolving credit 
facility, using the highest range of the ranges discussed above, is estimated to be approximately $2.7 million.  

See  Note  4,  “Marketable  Securities”  to  the  Consolidated  Financial  Statements  in  Part  II,  Item  8;  Management’s 
Discussion and Analysis of Financial Condition and Results of Operations, “Liquidity and Capital Resources,” in Part II, 
Item 7; and Risk Factors in Part I, Item 1A of this Annual Report on Form 10-K for a description of recent market events that 
may affect the value of the investments in our portfolio that we held as of June 30, 2017. 

As of June 30, 2017, we had net forward and option contracts to sell $62.3 million in foreign currency in order to hedge 
certain  currency  exposures  (see  Note  16,  “Derivative  Instruments  and  Hedging  Activities”  to  the  Consolidated  Financial 
Statements for additional details). If we had entered into these contracts on June 30, 2017, the U.S. dollar equivalent would 

63 

 
have been $57.7 million. A 10% adverse move in all currency exchange rates affecting the contracts would decrease the fair 
value of the contracts by $29.6 million. However, if this occurred, the fair value of the underlying exposures hedged by the 
contracts would increase by a similar amount. Accordingly, we believe that, as a result of the hedging of certain of our foreign 
currency exposure, changes in most relevant foreign currency exchange rates should have no material impact on our income 
or cash flows.

KLA-TENCOR CORPORATION 
Notes to Consolidated Financial Statements 

NOTE 1— DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Description  of  Business  and  Principles  of  Consolidation.  KLA-Tencor  Corporation  (“KLA-Tencor”  or  the 
“Company”)  is  a  leading  supplier  of  process  control  and  yield  management  solutions  for  the  semiconductor  and  related 
nanoelectronics industries. KLA-Tencor’s broad portfolio of inspection and metrology products, and related service, software 
and other offerings primarily supports integrated circuit, which is referred to as an “IC” or “chip,” manufacturers throughout 
the  entire  semiconductor  fabrication  process,  from  research  and  development  to  final  volume  production.  KLA-Tencor 
provides  leading-edge  equipment,  software  and  support  that  enable  IC  manufacturers  to  identify,  resolve  and  manage 
significant advanced technology manufacturing process challenges and obtain higher finished product yields at lower overall 
cost.  In  addition  to  serving  the  semiconductor  industry,  KLA-Tencor  also  provides  a  range  of  technology  solutions  to  a 
number of other high technology industries, including the advanced packaging, light emitting diode (“LED”), power devices, 
compound  semiconductor,  and  data  storage  industries,  as  well  as  general  materials  research.  Headquartered  in  Milpitas, 
California, KLA-Tencor has subsidiaries both in the United States and in key markets throughout the world. 

The Consolidated Financial Statements include the accounts of KLA-Tencor and its majority-owned subsidiaries. All 

significant intercompany balances and transactions have been eliminated. 

Terminated Merger Agreement. On October 20, 2015, the Company entered into an Agreement and Plan of Merger 
and Reorganization (the “Merger Agreement” or “Merger”) with Lam Research Corporation (“Lam Research”) which was 
subject to regulatory approvals. On October 5, 2016, the parties mutually agreed to terminate the Merger Agreement and no 
termination fees were payable by either party. 

Management  Estimates.  The  preparation  of  the  Consolidated  Financial  Statements  in  conformity  with  accounting 
principles generally accepted in the United States of America requires management to make estimates and assumptions in 
applying the Company’s accounting policies that affect the reported amounts of assets and liabilities (and related disclosure 
of contingent assets and liabilities) at the date of the Consolidated Financial Statements and the reported amounts of revenues 
and expenses during the reporting periods. Actual results could differ from those estimates. 

Cash Equivalents and Marketable Securities. All highly liquid debt instruments with original or remaining maturities 
of less than three months at the date of purchase are considered to be cash equivalents. Marketable securities are generally 
classified as available-for-sale for use in current operations, if required, and are reported at fair value, with unrealized gains 
and  losses,  net  of  tax,  presented  as  a  separate  component  of  stockholders’  equity  under  the  caption  “Accumulated  other 
comprehensive income (loss).” All realized gains and losses and unrealized losses resulting from declines in fair value that 
are other than temporary are recorded in earnings in the period of occurrence. The specific identification method is used to 
determine  the  realized  gains  and  losses  on  investments.  For  all  investments  in  debt  and  equity  securities,  the  Company 
assesses whether the impairment is other than temporary. If the fair value of a debt security is less than its amortized cost 
basis, an impairment is considered other than temporary if (i) the Company has the intent to sell the security or it is more 
likely than not that the Company will be required to sell the security before recovery of its entire amortized cost basis, or (ii) 
the Company does not expect to recover the entire amortized cost of the security. If an impairment is considered other than 
temporary  based  on  condition  (i),  the  entire  difference  between  the  amortized  cost  and  the  fair  value  of  the  security  is 
recognized in earnings. If an impairment is considered other than temporary based on condition (ii), the amount representing 
credit losses, defined as the difference between the present value of the cash flows expected to be collected and the amortized 
cost basis of the debt security, will be recognized in earnings, and the amount relating to all other factors will be recognized 
in other comprehensive income (loss). The Company evaluates both qualitative and quantitative factors such as duration and 
severity  of  the  unrealized  losses,  credit  ratings,  default  and  loss  rates  of  the  underlying  collateral,  structure  and  credit 
enhancements to determine if a credit loss may exist. 

70 

 
 
 
Non-Marketable Equity Securities and Other Investments. KLA-Tencor acquires certain equity investments for the 
promotion  of  business  and  strategic  objectives,  and,  to  the  extent  these  investments  continue  to  have  strategic  value,  the 
Company typically does not attempt to reduce or eliminate the inherent market risks. Non-marketable equity securities and 
other  investments  are  recorded  at  historical  cost.  Non-marketable  equity  securities  and  other  investments  are  included  in 
“Other non-current assets” on the balance sheet. Non-marketable equity securities are subject to a periodic impairment review; 
however,  there  are  no  open-market  valuations,  and  the  impairment  analysis  requires  significant  judgment.  This  analysis 
includes assessment of the investee’s financial condition, the business outlook for its products and technology, its projected 
results and cash flow, the likelihood of obtaining subsequent rounds of financing and the impact of any relevant contractual 
equity preferences held by the Company or others. 

Variable Interest Entities. KLA-Tencor uses a qualitative approach in assessing the consolidation requirement for 
variable interest entities. The approach focuses on identifying which enterprise has the power to direct the activities that most 
significantly impact the variable interest entity’s economic performance and which enterprise has the obligation to absorb 
losses or the right to receive benefits from the variable interest entity. In the event that the Company is the primary beneficiary 
of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity will be included in 
the  Company’s  Consolidated  Financial  Statements.  The  Company  has  concluded  that  none  of  the  Company’s  equity 
investments require consolidation as per the Company’s most recent qualitative assessment. 

Inventories. Inventories are stated at the lower of cost (on a first-in, first-out basis) or market. Demonstration units are 
stated at their manufacturing cost and written down to their net realizable value. The Company reviews and sets standard 
costs  semi-annually  at  current  manufacturing  costs  in  order  to  approximate  actual  costs.  The  Company’s  manufacturing 
overhead standards for product costs are calculated assuming full absorption of forecasted spending over projected volumes, 
adjusted for excess capacity. Abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and 
spoilage are recognized as current period charges. The Company writes down product inventory based on forecasted demand 
and technological obsolescence and service spare parts inventory based on forecasted usage. These factors are impacted by 
market  and  economic  conditions,  technology  changes,  new  product  introductions  and  changes  in  strategic  direction  and 
require  estimates  that  may  include  uncertain  elements.  Actual  demand  may  differ  from  forecasted  demand,  and  such 
differences may have a material effect on recorded inventory values. 

Allowance for Doubtful Accounts. A majority of the Company’s accounts receivable are derived from sales to large 
multinational semiconductor manufacturers throughout the world. In order to monitor potential credit losses, the Company 
performs ongoing credit evaluations of its customers’ financial condition. An allowance for doubtful accounts is maintained 
for probable credit losses based upon the Company’s assessment of the expected collectibility of the accounts receivable. The 
allowance for doubtful accounts is reviewed on a quarterly basis to assess the adequacy of the allowance. 

Property and Equipment. Property and equipment are recorded at cost, net of accumulated depreciation. Depreciation 
of property and equipment is based on the straight-line method over the estimated useful lives of the assets. The following 
table sets forth the estimated useful life for various asset categories: 

Asset Category 

Range of Useful Lives 

Buildings..................................................   30 to 35 years 
Leasehold improvements .........................   Shorter of 15 years or lease term 
Machinery and equipment .......................   2 to 5 years 
Office furniture and fixtures ....................   7 years 

Construction-in-process assets are not depreciated until the assets are placed in service. Depreciation expense for the 

fiscal years ended June 30, 2017, 2016 and 2015 was $49.1 million, $52.6 million and $55.8 million, respectively. 

71 

 
   
 
 
 
Goodwill  and  Purchased  Intangible  Assets.  KLA-Tencor  assesses  goodwill  for  impairment  annually  as  well  as 
whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Long-lived purchased 
intangible assets are tested for impairment whenever events or changes in circumstances indicate that their carrying amounts 
may not be recoverable. See Note 6, “Goodwill and Purchased Intangible Assets” for additional details.  

Impairment of Long-Lived Assets. KLA-Tencor evaluates the carrying value of its long-lived assets whenever events 
or changes in circumstances indicate that the carrying value of the asset may be impaired. An impairment loss is recognized 
when estimated future cash flows expected to result from the use of the asset, including disposition, are less than the carrying 
value of the asset. Such an impairment charge would be measured as the excess of the carrying value of the asset over its fair 
value. 

Concentration of Credit Risk. Financial instruments that potentially subject KLA-Tencor to significant concentrations 
of credit risk consist primarily of cash equivalents, short-term marketable securities, trade accounts receivable and derivative 
financial instruments used in hedging activities. The Company invests in a variety of financial instruments, such as, but not 
limited to, certificates of deposit, corporate debt and municipal securities, United States Treasury and Government agency 
securities, and equity securities and, by policy, limits the amount of credit exposure with any one financial institution or 
commercial issuer. The Company has not experienced any material credit losses on its investments. 

A  majority  of  the  Company’s  accounts  receivable  are  derived  from  sales  to  large  multinational  semiconductor 
manufacturers located throughout the world, with a majority located in Asia. In recent years, the Company’s customer base 
has become increasingly concentrated due to corporate consolidations, acquisitions and business closures, and to the extent 
that these customers experience liquidity issues in the future, the Company may be required to incur additional bad debt 
expense  with  respect  to  trade  receivables.  The  Company  performs  ongoing  credit  evaluations  of  its  customers’  financial 
condition  and  generally  requires  no  collateral  to  secure  accounts  receivable.  The  Company  maintains  an  allowance  for 
potential credit losses based upon expected collectibility risk of all accounts receivable. In addition, the Company may utilize 
letters of credit or non-recourse factoring to mitigate credit risk when considered appropriate. 

The  Company  is  exposed  to credit  loss  in  the  event of non-performance  by  counterparties  on  the  foreign  exchange 
contracts that the Company uses in hedging activities and in certain factoring transactions. These counterparties are large 
international financial institutions, and to date no such counterparty has failed to meet its financial obligations to the Company 
under such contracts.

Foreign Currency. The functional currencies of KLA-Tencor’s foreign subsidiaries are the local currencies, except as 
described below. Accordingly, all assets and liabilities of these foreign operations are translated to U.S. dollars at current 
period end exchange rates, and revenues and expenses are translated to U.S. dollars using average exchange rates in effect 
during  the  period.  The  gains  and  losses  from  foreign  currency  translation  of  these  subsidiaries’  financial  statements  are 
recorded directly into a separate component of stockholders’ equity under the caption “Accumulated other comprehensive 
income (loss).” 

The Company’s manufacturing subsidiaries in Singapore, Israel and Germany use the U.S. dollar as their functional 
currency. Accordingly, monetary assets and liabilities in non-functional currency of these subsidiaries are remeasured using 
exchange rates in effect at the end of the period. Revenues and costs in local currency are remeasured using average exchange 
rates for the period, except for costs related to those balance sheet items that are remeasured using historical exchange rates. 
The resulting remeasurement gains and losses are included in the Consolidated Statements of Operations as incurred. 

Derivative Financial Instruments. KLA-Tencor uses financial instruments, such as forward exchange contracts and 
currency options, to hedge a portion of, but not all, existing and forecasted foreign currency denominated transactions. The 
purpose of the Company’s foreign currency program is to manage the effect of exchange rate fluctuations on certain foreign 
currency denominated revenues, costs and eventual cash flows. The effect of exchange rate changes on forward exchange 
contracts is expected to offset the effect of exchange rate changes on the underlying hedged items. The Company believes 
these  financial  instruments  do  not  subject  the  Company  to  speculative  risk  that  would  otherwise  result  from  changes  in 
currency exchange rates. 

All of the Company’s derivative financial instruments are recorded at fair value based upon quoted market prices for 
comparable  instruments  adjusted  for  risk  of  counterparty  non-performance.  For  derivative  instruments  designated  and 
qualifying as cash flow hedges of forecasted foreign currency denominated transactions expected to occur within twelve to 
eighteen months, the effective portion of the gain or loss on these hedges is reported as a component of “Accumulated other 
comprehensive income (loss)” in stockholders’ equity, and is reclassified into earnings when the hedged transaction affects 
earnings. If the transaction being hedged fails to occur, or if a portion of any derivative is (or becomes) ineffective, the gain 
or loss on the associated financial instrument is recorded immediately in earnings. For derivative instruments used to hedge 
existing foreign currency denominated assets or liabilities, the gains or losses on these hedges are recorded immediately in 
earnings to offset the changes in the fair value of the assets or liabilities being hedged. 

Warranty. The Company provides standard warranty coverage on its systems for 40 hours per week for 12 months, 
providing labor and parts necessary to repair and maintain the systems during the warranty period. The Company accounts 
for the estimated warranty cost as a charge to costs of revenues when revenue is recognized. The estimated warranty cost is 
based on historical product performance and field expenses. Utilizing actual service records, the Company calculates the 
average service hours and parts expense per system and applies the actual labor and overhead rates to determine the estimated 
warranty charge. The Company updates these estimated charges on a regular basis. The actual product performance and/or 
field expense profiles may differ, and in those cases the Company adjusts its warranty accruals accordingly (see Note 13, 
“Commitments and Contingencies”). 

Revenue Recognition. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery 
has occurred or services have been rendered, the selling price is fixed or determinable, and collectibility is reasonably assured. 
The  Company  derives  revenue  from  three  sources—sales  of  systems,  spare  parts  and  services.  In  general,  the  Company 
recognizes revenue for systems when the system has been installed, is operating according to predetermined specifications 
and is accepted by the customer. When the Company has demonstrated a history of successful installation and acceptance, 
the  Company  recognizes  revenue  upon  delivery  and  customer  acceptance.  Under  certain  circumstances,  however,  the 
Company recognizes revenue prior to acceptance from the customer, as follows: 

•  When the customer fab has previously accepted the same tool, with the same specifications, and when the Company

can objectively demonstrate that the tool meets all of the required acceptance criteria. 

73 

 
 
 
 
 
•  When system sales to independent distributors have no installation requirement, contain no acceptance agreement,

and 100% of the payment is due based upon shipment. 

•  When the installation of the system is deemed perfunctory. 

•  When the customer withholds acceptance due to issues unrelated to product performance, in which case revenue is

recognized when the system is performing as intended and meets predetermined specifications. 

In circumstances in which the Company recognizes revenue prior to installation, the portion of revenue associated with 

installation is deferred based on estimated fair value, and that revenue is recognized upon completion of the installation. 

In  many  instances,  products  are  sold  in  stand-alone  arrangements.  Services  are  sold separately  through renewals of 
annual maintenance contracts. The Company has multiple element revenue arrangements in cases where certain elements of 
a  sales  arrangement  are  not  delivered  and  accepted  in  one  reporting  period.  To  determine  the  relative  fair  value  of  each 
element in a revenue arrangement, the Company allocates arrangement consideration based on the selling price hierarchy. 
For substantially all of the arrangements with multiple deliverables pertaining to products and services, the Company uses 
vendor-specific objective evidence (“VSOE”) or third-party evidence (“TPE”) to allocate the selling price to each deliverable. 
The Company determines TPE based on historical prices charged for products and services when sold on a stand-alone basis. 
When the Company is unable to establish relative selling price using VSOE or TPE, the Company uses estimated selling 
price (“ESP”) in its allocation of arrangement consideration. The objective of ESP is to determine the price at which the 
Company would transact a sale if the product or service were sold on a stand-alone basis. ESP could potentially be used for 
new or customized products. The Company regularly reviews relative selling prices and maintains internal controls over the 
establishment and updates of these estimates. 

In a multiple element revenue arrangement, the Company defers revenue recognition associated with the relative fair 
value of each undelivered element until that element is delivered to the customer. To be considered a separate element, the 
product or service in question must represent a separate unit of accounting, which means that such product or service must 
fulfill  the  following  criteria:  (a)  the  delivered  item(s)  has  value  to  the  customer  on  a  stand-alone  basis;  and  (b)  if  the 
arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered  

item(s) is considered probable and substantially in the control of the Company. If the arrangement does not meet all the above 
criteria, the entire amount of the sales contract is deferred until all elements are accepted by the customer. 

Trade-in rights are occasionally granted to customers to trade in tools in connection with subsequent purchases. The 
Company estimates the value of the trade-in right and reduces the revenue recognized on the initial sale. This amount is 
recognized at the earlier of the exercise of the trade-in right or the expiration of the trade-in right. 

The Company enters into volume purchase agreements with some of its customers. The Company accrues the estimated 
credits earned by its customers for such incentives, and in situations when the credit levels vary depending upon sales volume, 
the Company updates its accrual based on the amount that the Company estimates will be purchased pursuant to the volume 
purchase agreements. Accruals for customer credits are recorded as an offset to revenue or deferred revenue. 

 Spare parts revenue  is  recognized when  the  product  has been  shipped, risk of  loss  has  passed  to  the  customer  and 

collection of the resulting receivable is probable. 

Service and maintenance contract revenue is recognized ratably over the term of the maintenance contract. Revenue 
from services performed in the absence of a maintenance contract, including consulting and training revenue, is recognized 
when the related services are performed and collectibility is reasonably assured. 

The  Company  sells  stand-alone  software  that  is  subject  to  software  revenue  recognition  guidance.  The  Company 
periodically reviews selling prices to determine whether VSOE exists, and in situations where the Company is unable to 
establish VSOE for undelivered elements such as post-contract service, revenue is recognized ratably over the term of the 
service contract. 

74 

 
 
 
 
 
The Company also defers the fair value of non-standard warranty bundled with equipment sales as unearned revenue. 
Non-standard warranty includes services incremental to the standard 40-hour per week coverage for 12 months. Non-standard 
warranty is recognized ratably as revenue when the applicable warranty term period commences.  

The deferred system profit balance equals the value of products that have been shipped and billed to customers which 
have not met the Company’s revenue recognition criteria, less applicable product and warranty costs. Deferred system profit 
does not include the profit associated with product shipments to certain customers in Japan, to whom title does not transfer 
until  customer  acceptance.  Shipments  to  such  customers  in  Japan  are  classified  as  inventory  at  cost  until  the  time  of 
acceptance. 

Research and Development Costs. Research and development costs are expensed as incurred. 

Shipping and Handling Costs. Shipping and handling costs are included as a component of cost of sales. 

Accounting  for  Stock-Based  Compensation  Plans.  The  Company  accounts  for  stock-based  awards  granted  to 
employees for services based on the fair value of those awards. The fair value of stock-based awards is measured at the grant 
date and is recognized as expense over the employee’s requisite service period. The fair value for restricted stock units granted 
without “dividend equivalent” rights is determined using the closing price of the Company’s common stock on the grant date, 
adjusted to exclude the present value of dividends which are not accrued on the restricted stock units. The fair value for 
restricted  stock  units  granted  with  “dividend  equivalent”  rights  is  determined  using  the  closing  price  of  the  Company’s 
common stock on the grant date. The award holder is not entitled to receive payments under dividend equivalent rights unless 
the associated restricted stock unit award vests (i.e., the award holder is entitled to receive credits, payable in cash or shares 
of the Company’s common stock, equal to the cash dividends that would have been received on the shares of common stock 
underlying the restricted stock units had the shares been issued and outstanding on the dividend record date, but such dividend 
equivalents are only paid subject to the recipient satisfying the vesting requirements of the underlying award). Additionally, 
the Company estimates forfeitures based on historical experience and revises those estimates in subsequent periods if actual 
forfeitures  differ  from  the  estimated  amounts.  The  fair  value  is  determined  using  a  Black-Scholes  valuation  model  for 
purchase  rights  under  the  Employee  Stock  Purchase  Plan.  The  Black-Scholes  option-pricing  model  requires  the  input  of 
assumptions, including the option’s expected term and the expected price volatility of the underlying stock. The expected 
stock  price  volatility  assumption  is  based  on  the  market-based  historical  implied  volatility  from  traded  options  of  the 
Company’s common stock.  

Accounting  for  Cash-Based  Long-Term  Incentive  Compensation.  Cash-based  long-term  incentive  (“Cash  LTI”) 
awards issued to employees under the Company’s Cash LTI program vests in three or four equal installments, with one-third 
or one-fourth of the aggregate amount of the Cash LTI award vesting on each yearly anniversary of the grant date over a three 
or  four-year  period.  In  order  to  receive  payments  under  a  Cash  LTI  award,  participants  must  remain  employed  by  the 
Company as of the applicable award vesting date. Compensation expense related to the Cash LTI awards is recognized over 
the vesting term, which is adjusted for the impact of estimated forfeitures.  

Accounting  for  Non-qualified  Deferred  Compensation  Plan.  The  Company  has  a  non-qualified  deferred 
compensation  plan  (known  as  “Executive  Deferred  Savings  Plan”)  under  which  certain  executives  and  non-employee 
directors may defer a portion of their compensation. Participants are credited with returns based on their allocation of their 
account  balances  among  measurement  funds.  The  Company  controls  the  investment  of  these  funds,  and  the  participants 
remain general creditors of the Company. The Company invests these funds in certain mutual funds and such investments are 
classified as trading securities in the consolidated balance sheets. Distributions from the Executive Deferred Savings Plan 
commence following a participant’s retirement or termination of employment or on a specified date allowed per the Executive 
Deferred Savings Plan provisions, except in cases where such distributions are required to be delayed in order to avoid a 
prohibited distribution under Internal Revenue Code Section 409A. Participants can generally elect the distributions to be 
paid in lump sum or quarterly cash payments over a scheduled period for up to 15 years and are allowed to make subsequent 
changes  to  their  existing  elections  as  permissible  under  the  Executive  Deferred  Savings  Plan  provisions.  The  liability 
associated with the Executive Deferred Savings Plan is included as a component of other current liabilities in the consolidated 

75 

 
balance sheets. Changes in the Executive Deferred Savings Plan liability is recorded in selling, general and administrative 
expense in the consolidated statements of operations. The expense (benefit) associated with changes in the liability included 
in selling, general and administrative expense was $20.9 million, $(0.8) million and $10.4 million for the fiscal years ended 
June 30, 2017, 2016 and 2015, respectively. The Company also has a deferred compensation asset that corresponds to the 
liability  under  the  Executive  Deferred  Savings  Plan  and  it  is  included  as  a  component  of  other  non-current  assets  in  the 
consolidated balance sheets. Changes in the Executive Deferred Savings Plan assets are recorded as gains (losses), net in 
selling, general and administrative expense in the consolidated statements of operations. The amount of net gains included in 
selling, general and administrative expense were $20.8 million, $0.1 million and $10.4 million for the fiscal years ended 
June 30, 2017, 2016 and 2015, respectively. 

Income Taxes. The Company accounts for income taxes in accordance with the authoritative guidance, which requires 
that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between 
the book and tax bases of recorded assets and liabilities. The guidance also requires that deferred tax assets be reduced by a 
valuation  allowance  if  it  is  more  likely  than  not  that  certain  deferred  tax  asset  will  not  be  realized.  The  Company  has 
determined that a valuation allowance is necessary against certain deferred tax assets, but it anticipates that its future taxable 
income  will  be  sufficient  to  recover  the  remainder  of  its  deferred  tax  assets.  However,  should  there  be  a  change  in  the 
Company’s ability to recover its deferred tax assets that are not subject to a valuation allowance, the Company could be 
required to record an additional valuation allowance against such deferred tax assets. This would result in an increase to the 
Company’s tax provision in the period in which the Company determines that the recovery is not probable.  

The Company applies a two-step approach, based on authoritative guidance, to recognizing and measuring uncertain 
tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence 
indicates that it is more likely than not that the position will be sustained in audit, including resolution of related appeals or 
litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely 
of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This 
evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively 
settled issues under audit and new audit activity. Any change in these factors could result in the recognition of a tax benefit 
or an additional charge to the tax provision. 

Net  Income  Per  Share.  Basic  net  income  per  share  is  calculated  by  dividing  net  income  available  to  common 
stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share 
is calculated by using the weighted-average number of common shares outstanding during the period increased to include the 
number of additional shares of common stock that would have been outstanding if the dilutive potential shares of common 
stock had been issued. The dilutive effect of restricted stock units and options is reflected in diluted net income per share by 
application of the treasury stock method. The dilutive securities are excluded from the computation of diluted net loss per 
share when a net loss is recorded for the period as their effect would be anti-dilutive. 

Contingencies  and  Litigation.  The  Company  is  subject  to  the  possibility  of  losses  from  various  contingencies. 
Considerable judgment is necessary to estimate the probability and amount of any loss from such contingencies. An accrual 
is made when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be 
reasonably estimated. The Company accrues a liability and recognizes as expense the estimated costs expected to be incurred 
over the next twelve months to defend or settle asserted and unasserted claims existing as of the balance sheet date. See Note 
13, “Commitments and Contingencies” and Note 14, “Litigation and Other Legal Matters” for additional details. 

Reclassifications. Certain reclassifications have been made to prior year financial statements to conform to the current 
year presentation. The reclassifications had no effect on the Consolidated Statements of Operations, Comprehensive Income, 
Stockholder’s Equity and Cash Flows.

Recent Accounting Pronouncements  

Recently Adopted 

In  April  2015,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  an  accounting  standard  update  for 
customer’s cloud based fees. The guidance changes what a customer must consider in determining whether a cloud computing 
arrangement contains a software license. If the arrangement contains a software license, the customer would account for the 
fees related to the software license element in accordance with guidance related to internal use software; if the arrangement 
does not contain a software license, the customer would account for the arrangement as a service contract. The Company 
adopted this update beginning in the first quarter of its fiscal year ended June 30, 2017 on a prospective basis and there was 
no impact of adoption on its consolidated financial statements. 

In September 2015, the FASB issued an accounting standard update on simplifying the accounting for measurement-
period adjustments for business combinations. This standard requires an acquirer in a business combination to recognize an 
impact of a measurement period adjustment in the reporting period in which the adjustment amounts are determined, rather 
than retrospectively adjusting previously reported amounts. The standard is effective for the Company beginning in the first 
quarter of its fiscal year ended June 30, 2017.  The Company adopted the standard in the fiscal year ended June 30, 2017 and 
there was no impact of adoption on its consolidated financial statements. 

In March 2016, the FASB issued an accounting standard update to simplify certain aspects of share-based payment 
awards to employees, including the accounting for income taxes, an option to recognize gross stock-based compensation 
expense  with  actual  forfeitures  recognized  as  they  occur  and  statutory  tax  withholding  requirements,  as  well  as  certain 
classifications in the statement of cash flows. The update is effective for the Company beginning in the first quarter of its 
fiscal year ending June 30, 2018, with early adoption permitted and all of the guidance must be adopted in the same period. 
However, the Company elected to early-adopt this standard update beginning in the first quarter of its fiscal year ended June 
30, 2017. 

Impact to Consolidated Statements of Operations 

The primary impact of adopting the standard update is a change in the recording of the excess tax benefits or deficiencies 
from share-based payments. Before adoption, the Company recognized the excess tax benefits or deficiencies related to stock-
based compensation as a credit or charge to additional paid-in capital (“APIC”) in the Company’s Consolidated Balance 
Sheets. Under the standard update, these excess tax benefits or deficiencies are recognized as a discrete tax benefit or discrete 
tax expense in the income tax provision in the Company’s Consolidated Statement of Operations. For the fiscal year ended 
June 30, 2017, the Company recognized a discrete tax benefit of $6.6 million related to net excess tax benefits mainly from 
stock-based compensation and dividend equivalents. The standard update requires companies to adopt the amendment related 
to  accounting  for  excess  tax  benefits  or  deficiencies  on  a  prospective  basis  only  and  as  a  result,  prior  periods  were  not 
retrospectively adjusted.  

Impact to Consolidated Statements of Cash Flows 

In addition to the income tax consequence as described above, the standard update for share-based payment requires 
that cash flows from excess tax benefits related to share-based payments be reported as operating activities in the Consolidated 
Statements of Cash Flows. Previously, cash flows from excess tax benefit related to share-based payments were reported as 
financing  activities.  The  standard  update  allows  for  two  methods  of  adoption  which  are  prospective  or  retrospective 
application. The Company elected to adopt this amendment on a prospective basis and as a result, prior periods were not 
retrospectively adjusted. 

Updates Not Yet Effective 

In May 2014, the FASB issued an accounting standard update regarding revenue from customer contracts to transfer 
goods and services or non-financial assets unless the contracts are covered by other standards (for example, insurance or lease 
contracts). Under the new guidance, an entity should recognize revenue in connection with the transfer of promised goods or 

77 

 
services to customers in an amount that reflects the consideration that the entity expects to be entitled to receive in exchange 
for  those  goods  or  services. In  addition,  the  new  standard requires  that reporting  companies disclose the nature,  amount, 
timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new standard is effective for 
the Company beginning in the first quarter of its fiscal year ending June 30, 2019 with early adoption permitted beginning in 
the first quarter of its fiscal year ending June 30, 2018. The new standard may be applied retrospectively to each prior period 
presented (“full retrospective transition method”) or retrospectively with the cumulative effect recognized as of the date of 
adoption (“modified retrospective transition method”). The FASB has also issued several amendments to the standard since 
its initial issuance. The Company intends to adopt the new standard in the first quarter of its fiscal year ending June 30, 2019 
and elected a modified retrospective transition method to be applied to completed and incomplete contracts as of adoption 
date.  

To  address  the  significant  implementation  requirements  of  the  accounting  standard  update,  the  Company  has 
established a revenue project steering committee and cross-functional implementation team for the implementation of the 
standard, including a review of all significant revenue arrangements to identify any differences in the timing, measurement, 
presentation of revenue recognition including new disclosure requirements.  

The Company has completed its preliminary assessment of the potential impact that the implementation of this new 
standard will have on its consolidated financial statements and believes the most significant impact may include the following: 

• 

• 

• 

The Company will account for the standard 12-month warranty for a majority of its products that is not separately
paid for by the customers as a performance obligation since the Company provides for necessary repairs as well as
preventive  maintenance  services  for  such  products.  The  estimated  fair  value  of  the  service  will  be  deferred  and
recognized ratably as revenue over the warranty period. 

The Company will generally recognize revenue for its products at a point of time based on judgment of whether or
not the Company has satisfied its performance obligation by transferring control of the product to the customer. In
evaluating whether or not control has been transferred to the customer, the Company will consider whether or not
certain indicators have been met. Not all of the indicators need to be met for the Company to conclude that control
has transferred to the customer. The Company will be required to use significant judgment to evaluate whether or
not  the  factors  indicate  that  the  customer  has  obtained  control  of  the  product  and  the  following  factors  will  be
considered in evaluating whether or not control has transferred to the customer: the Company has a present right to
payment; the customer has legal title; the customer has physical possession; the customer has significant risk and
rewards of ownership; and the customer has accepted the product, or whether customer acceptance is considered a
formality based on history of acceptance of similar products.  

The  Company  will  recognize  revenue  for  software  licenses  at  the  time  of  delivery  since  the  Vendor  Specific
Objective Evidence (“VSOE”) requirement for undelivered element such as post-contract support is eliminated and
companies are allowed to use established or best estimate selling price for the undelivered element to allocate and
defer the revenue. As a result, the Company will recognize as revenue a portion of the sales price upon delivery of
the software, compared to the current practice of recognizing the entire sales price ratably over the term of the service
contract due to the lack of VSOE.  

The Company will continue to assess the impact of the new standard, including potential changes to the accounting 
policies,  business  processes,  systems  and  internal  controls  over  financial  reporting  and  its  preliminary  assessment  of  the 
impact is subject to change.  

In  July  2015,  the  FASB  issued  an  accounting  standard  update  for  the  subsequent  measurement  of  inventory.  The 
amended guidance requires entities to measure inventory at the lower of cost or net realizable value. Net realizable value is 
the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and 
transportation. The requirement would replace the current lower of cost or market evaluation and the accounting guidance is 
unchanged for inventory measured using last-in, first-out (“LIFO”) or the retail inventory method. The update is effective for 

78 

 
 
   
 
 
 
 
 
 
the  Company  beginning  in  the  first  quarter  of  the  Company’s  fiscal  year  ending  June  30,  2018  and  should  be  applied 
prospectively with early adoption permitted as of the beginning of an interim or annual reporting period. The Company does 
not  expect  that  this  accounting  standard  update  will  have  a  material  effect  on  its  consolidated  financial  statements  upon 
adoption. 

In January 2016, the FASB issued an accounting standard update that changes the accounting for financial instruments 
primarily related to equity investments (other than those accounted for under the equity method of accounting or those that 
result in consolidation of the investee), financial liabilities under the fair value option, and the presentation and disclosure 
requirements for financial instruments. The accounting standard update is effective for the Company beginning in the first 
quarter of its fiscal year ending 2019, and early adoption is permitted. The Company is currently evaluating the impact of this 
accounting standard update on its consolidated financial statements. 

In February 2016, the FASB issued an accounting standard update which amends the existing accounting standards for 
leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising 
from a lease by a lessee primarily will depend on its classification. Under the new guidance, a lessee will be required to 
recognize assets and liabilities for all leases with lease terms of more than 12 months. The update is effective for the Company 
beginning in the first quarter of its fiscal year ending June 30, 2020 using a modified retrospective transition method. Early 
adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated 
financial statements. 

In June 2016, the FASB issued an accounting standard update that changes the accounting for recognizing impairments 
of  financial  assets.  Under  the  update,  credit  losses  for  certain  types  of  financial  instruments  will  be  estimated  based  on 
expected losses. The update also modifies the impairment models for available-for-sale debt securities and for purchased 
financial assets with credit deterioration since their origination. The update is effective for the Company beginning in the first 
quarter of its fiscal year ending June 30, 2021, with early adoption permitted starting in the first quarter of fiscal year ending 
2020.  The  Company  is  currently  evaluating  the  impact  of  this  accounting  standard  update  on  its  consolidated  financial 
statements. 

In October 2016, the FASB issued an accounting standard update to recognize the income tax consequences of intra-
entity transfers of assets other than inventory when they occur. This eliminates the exception to postpone recognition until 
the asset has been sold to an outside party. This standard is effective for the Company beginning in the first quarter of its 
fiscal year ending 2019, and early adoption is permitted. It is required to be applied on a modified retrospective basis through 
a  cumulative-effect  adjustment  to  the  balance  sheet  as  of  the  beginning  of  the  fiscal  year  of  adoption.  The  Company  is 
currently evaluating the impact of this accounting standard update on its consolidated financial statements. 

In January 2017, the FASB issued an accounting standard update to simplify the subsequent measurement of goodwill 
by removing the second step of the two-step impairment test, which requires an entity to determine the fair value of assets 
and  liabilities  similar  to  what  is  required  in  a  purchase  price  allocation.  Under  the  update,  goodwill  impairment  will  be 
calculated as the amount by which a reporting unit's carrying value exceeds its fair value. This standard is effective for the 
Company beginning in the first quarter of its fiscal year ending 2021 and requires a prospective approach to adoption. Early 
adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated 
financial statements. 

In January 2017, the FASB issued an accounting standard on clarifying the definition of a business, with the objective 
of  adding  guidance  to  assist  entities  with  evaluating  whether  transactions  should  be  accounted  for  as  acquisitions  (or 
disposals) of assets or businesses. The standard is effective for the Company for its fiscal year ending June 30, 2019.  The 
Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.   

In March 2017, the FASB issued an accounting standard update that changes the income statement classification of net 
periodic benefit cost related to defined benefit pension and/or other postretirement benefit plans. Under the update, employers 
will present the service cost component of net periodic benefit cost in the same statement of operations line item(s) as other 
employee  compensation  costs  arising  from  services  rendered during  the period. Only  the  service  cost  component  will  be 

79 

 
eligible for capitalization in assets. Employers will present the other components of the net periodic benefit costs separately 
from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. The 
standard is effective for the Company beginning in the first quarter of its fiscal year ending June 30, 2019 and early adoption 
is permitted. It is required to be applied retrospectively, except for the provision regarding capitalization in assets which is 
required to be applied prospectively. The Company is currently evaluating the impact of this accounting standard update on 
its consolidated financial statements. 

In May 2017, the FASB issued an accounting standard update regarding stock compensation that provides guidance 
about which changes to the terms and conditions of a share-based payment award require an entity to apply modification 
accounting in order to reduce diversity in practice and reduce complexity.   The update is effective for the Company beginning 
in the first quarter of the Company’s fiscal year ending June 30, 2019 and should be applied prospectively with early adoption 
permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact of 
this accounting standard update on its consolidated financial statements.  

NOTE 2 — FAIR VALUE MEASUREMENTS 

The  Company’s  financial  assets  and  liabilities  are  measured  and  recorded  at  fair  value,  except  for  certain  equity 
investments in privately-held companies. These equity investments are generally accounted for under the cost method of 
accounting and are periodically assessed for other-than-temporary impairment when an event or circumstance indicates that 
an  other-than-temporary  decline  in  value  may  have  occurred.  The  Company’s  non-financial  assets,  such  as  goodwill, 
intangible assets, and land, property and equipment, are recorded at cost and are assessed for impairment when an event or 
circumstance indicates that an other-than-temporary decline in value may have occurred. 

Fair Value of Financial Instruments. KLA-Tencor has evaluated the estimated fair value of financial instruments 
using available market information and valuations as provided by third-party sources. The use of different market assumptions 
and/or estimation methodologies could have a significant effect on the estimated fair value amounts. The fair value of the 
Company’s cash equivalents, accounts receivable, accounts payable and other current assets and liabilities approximate their 
carrying amounts due to the relatively short maturity of these items. 

Fair Value Hierarchy. The authoritative guidance for fair value measurements establishes a fair value hierarchy that 
prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted 
quoted  prices  in  active  markets  for  identical  assets  or  liabilities  (Level  1  measurements)  and  the  lowest  priority  to 
unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: 

Level 1 

Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the 
ability to access. 

Level 2 

    Valuations  based  on  quoted  prices  for  similar  assets  or  liabilities,  quoted  prices  in  markets  that  are  not 
active, or other inputs that are observable or can be corroborated by observable data for substantially the 
full term of the assets or liabilities. 

Level 3 

    Valuations based on inputs that are supported by little or no market activity and that are significant to the 

fair value of the assets or liabilities. 

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant 

to the fair value measurement. 

The Company’s financial instruments were classified within Level 1 or Level 2 of the fair value hierarchy as of June 30, 
2017,  because  they  were  valued  using  quoted  market  prices,  broker/dealer  quotes  or  alternative  pricing  sources  with 
observable levels of price transparency. As of June 30, 2017, the types of instruments valued based on quoted market prices 
in active markets included money market funds, U.S. Treasury securities and certain U.S. Government agency securities. 
Such instruments are generally classified within Level 1 of the fair value hierarchy. 

80 

 
   
 
 
   
  
     
  
     
As of June 30, 2017, the types of instruments valued based on other observable inputs included corporate debt securities, 
sovereign  securities  and  certain  U.S.  Government  agency  securities  .  The  market  inputs  used  to  value  these  instruments 
generally consist of market yields, reported trades and broker/dealer quotes. Such instruments are generally classified within 
Level 2 of the fair value hierarchy. 

The principal market in which the Company executes its foreign currency contracts is the institutional market in an 
over-the-counter environment with a relatively high level of price transparency. The market participants generally are large 
financial institutions. The Company’s foreign currency contracts’ valuation inputs are based on quoted prices and quoted 
pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified 
within Level 2 of the fair value hierarchy. 

Financial assets (excluding cash held in operating accounts and time deposits) and liabilities measured at fair value on 

a recurring basis as of the date indicated below were presented on the Company’s Consolidated Balance Sheet as follows:

KLA-Tencor’s investment portfolio consists of both corporate and government securities that have a maximum maturity 
of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates 
and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. All 
unrealized losses are due to changes in market interest rates, bond yields and/or credit ratings. The Company believes that it 
has the ability to realize the full value of all of these investments upon maturity. The following table summarizes the fair 
value  and  gross  unrealized  losses  of  the  Company’s  investments  that  were  in  an  unrealized  loss  position  as  of  the  date 
indicated below:

NOTE 5 - BUSINESS COMBINATION 

On June 9, 2017, the Company completed the acquisition of the outstanding shares of a privately-held company that 
designs and manufactures optical profilers and defect inspection systems for advanced semiconductor packaging, LED and 
data storage industries, for total purchase consideration of $36.9 million, including cash paid of $31.6 million at closing. The 
remaining acquisition holdback amount of $5.3 million will be paid before the end of calendar year 2017. The primary reason 
for the acquisition is to expand the Company’s portfolio of products. 

The following table represents the preliminary purchase price allocation and summarizes the aggregate estimated fair 

value of the net assets acquired on the closing date of the acquisition:

The operating results of the acquired entity have been included in the Company’s consolidated financial statements 
for the fiscal year ending June 30, 2017. Goodwill represents the excess of the purchase price over the fair value of the net 
tangible and identifiable intangible assets acquired. The $14.3 million of goodwill was assigned to the Global Service and 
Support (“GSS”), and the Other reporting units. None of the goodwill recognized is deductible for income tax purposes. 

NOTE 6 — GOODWILL AND PURCHASED INTANGIBLE ASSETS 

Goodwill 

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible 
assets acquired in the current and prior business combinations. The Company has four reporting units: Wafer Inspection, 
Patterning, GSS, and Others. The following table presents goodwill balances and the movements by reporting unit during the

The Company made certain organizational changes and consolidated its product division effective in the first quarter 
of fiscal 2016. The reorganization resulted in the reallocation of certain goodwill balances as noted above. 
 Goodwill is net of accumulated impairment losses of $277.6 million, which were recorded prior to the fiscal year ended 
June 30, 2014. The acquired goodwill during the fiscal year ended June 30, 2017 resulted from the acquisition of certain 
assets and liabilities of a privately-held company. See Note 5 “Business Combination” for additional details.  

The Company performed a qualitative assessment of the goodwill by reporting unit as of November 30, 2016 during 
the three months ended December 31, 2016 and concluded that it was more likely than not that the fair value of each of the 
reporting units exceeded its carrying amount. In assessing the qualitative factors, the Company considered the impact of key 
factors  including  change  in  industry  and  competitive  environment,  market  capitalization,  stock  price,  earnings  multiples, 
budgeted-to-actual revenue performance from prior year, gross margin and cash flow from operating activities. As such, it 
was not necessary to perform the two-step quantitative goodwill impairment test at that time. In addition, there have been no 
significant events or circumstances affecting the valuation of goodwill subsequent to the qualitative assessment performed in 
the  second  quarter  of  the  fiscal  year  ended  June  30,  2017.  The  next  annual  assessment  of  goodwill  by  reporting  unit  is 
scheduled to be performed in the second quarter of the fiscal year ending June 30, 2018.

Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying 

amount of an asset or asset group may not be recoverable.  

For the fiscal years ended June 30, 2017, 2016 and 2015, amortization expense for purchased intangible assets was $3.0 
million, $7.6 million and $15.8 million, respectively. The increase in the gross carrying value resulted from the acquisition 
of  a  privately-held  company.  See  Note  5  “Business  Combination”  for  additional  details.  Based  on  the  intangible  assets 
recorded as of June 30, 2017, and assuming no subsequent additions to, or impairment of, the underlying assets, the remaining 
estimated annual amortization expense is expected to be as follows:

Senior Notes:  

In November 2014, the Company issued $2.50 billion aggregate principal amount of senior, unsecured long-term notes 
(collectively referred to as “Senior Notes”). The Company issued the Senior Notes as part of the leveraged recapitalization 
plan under which the proceeds from the Senior Notes in conjunction with the proceeds from the term loans (described below) 
and cash on hand were used (x) to fund a special cash dividend of $16.50 per share, aggregating to approximately $2.76 
billion, (y) to redeem $750.0 million of 2018 Senior Notes, including associated redemption premiums, accrued interest and 
other  fees  and  expenses  and  (z)  for  other  general  corporate  purposes,  including  repurchases  of  shares  pursuant  to  the 
Company’s  stock  repurchase  program.  The  interest  rate  specified  for  each  series  of  the  Senior  Notes  will  be  subject  to 
adjustments from time to time if Moody’s Investor Service, Inc. (“Moody’s”) or Standard & Poor’s Ratings Services (“S&P”) 
or, under certain circumstances, a substitute rating agency selected by us as a replacement for Moody’s or S&P, as the case

may be (a “Substitute Rating Agency”), downgrades (or subsequently upgrades) its rating assigned to the respective series of 
Senior Notes such that the adjusted rating is below investment grade. If the adjusted rating of any series of Senior Notes from 
Moody’s (or, if applicable, any Substitute Rating Agency) is decreased to Ba1, Ba2, Ba3 or B1 or below, the stated interest 
rate on such series of Senior Notes as noted above will increase by 25 bps, 50 bps, 75 bps or 100 bps, respectively (“bps” 
refers to Basis Points and 1% is equal to 100 bps). If the rating of any series of Senior Notes from S&P (or, if applicable, any 
Substitute Rating Agency) with respect to such series of Senior Notes is decreased to BB+, BB, BB- or B+ or below, the 
stated  interest  rate  on  such  series  of  Senior  Notes  as  noted  above  will  increase  by  25  bps,  50  bps,  75  bps  or  100  bps, 
respectively.  The  interest  rates  on  any  series  of  Senior  Notes  will  permanently  cease  to  be  subject  to  any  adjustment 
(notwithstanding any subsequent decrease in the ratings by any of Moody’s, S&P and, if applicable, any Substitute Rating 
Agency) if such series of Senior Notes becomes rated “Baa1” (or its equivalent) or higher by Moody’s (or, if applicable, any 
Substitute Rating Agency) and “BBB+” (or its equivalent) or higher by S&P (or, if applicable, any Substitute Rating Agency), 
or one of those ratings if rated by only one of Moody’s, S&P and, if applicable, any Substitute Rating Agency, in each case 
with a stable or positive outlook. In October 2014, the Company entered into a series of forward contracts to lock the 10-year 
treasury rate (“benchmark rate”) on a portion of the Senior Notes with a notional amount of $1.00 billion in aggregate. For 
additional details, refer to Note 16, “Derivative Instruments and Hedging Activities.”  

The original discount on the Senior Notes amounted to $4.0 million and is being amortized over the life of the debt. 
Interest is payable semi-annually on May 1 and November 1 of each year. The debt indenture (the “Indenture”) includes 
covenants that limit the Company’s ability to grant liens on its facilities and enter into sale and leaseback transactions, subject 
to certain allowances under which certain sale and leaseback transactions are not restricted. As of June 30, 2017, the Company 
was in compliance with all of its covenants under the Indenture associated with the Senior Notes. 

In certain circumstances involving a change of control followed by a downgrade of the rating of a series of Senior Notes 
by at least two of Moody’s, S&P and Fitch Inc., unless the Company has exercised its right to redeem the Senior Notes of 
such series, the Company will be required to make an offer to repurchase all or, at the holder’s option, any part, of each 
holder’s Senior Notes of that series pursuant to the offer described below (the “Change of Control Offer”). In the Change of 
Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of 
Senior Notes repurchased plus accrued and unpaid interest, if any, on the Senior Notes repurchased, up to, but not including, 
the date of repurchase.  

Based on the trading prices of the Senior Notes on the applicable dates, the fair value of the Senior Notes as of June 30, 
2017 and June 30, 2016 was approximately $2.67 billion and $2.68 billion, respectively. While the Senior Notes are recorded 
at cost, the fair value of the long-term debt was determined based on quoted prices in markets that are not active; accordingly, 
the long-term debt is categorized as Level 2 for purposes of the fair value measurement hierarchy. 

Credit Facility (Term Loans and Unfunded Revolving Credit Facility): 

In November 2014, the Company entered into $750.0 million of five-year senior unsecured prepayable term loans and 
a  $500.0  million  unfunded  revolving  credit  facility  (collectively,  the  “Credit  Facility”)  under  the  Credit  Agreement  (the 
“Credit Agreement”). The interest under the Credit Facility will be payable on the borrowed amounts at the London Interbank 
Offered Rate (“LIBOR”) plus a spread, which is currently 125 bps, and this spread is subject to adjustment in conjunction 
with  the  Company’s  credit  rating  downgrades  or  upgrades.  The  spread  ranges  from  100  bps  to  175  bps  based  on  the 
Company’s then effective credit rating. The Company is also obligated to pay an annual commitment fee of 15 bps on the 
daily  undrawn  balance  of  the  revolving  credit  facility,  which  is  also  subject  to  an  adjustment  in  conjunction  with  the 
Company’s credit rating downgrades or upgrades by Moody’s and S&P. The annual commitment fee ranges from 10 bps to 
25 bps on the daily undrawn balance of the revolving credit facility, depending upon the then effective credit rating. Principal 
payments with respect to the term loans will be made on the last day of each calendar quarter, and any unpaid principal 
balance of the term loans, including accrued interest, shall be payable on November 14, 2019 (the “Maturity Date”). The 
Company may prepay the term loans and unfunded revolving credit facility at any time without a prepayment penalty. During 
the year ended June 30, 2017, the Company made term loan principal payments of $130.0 million. The remaining term loan 
balance of $446.3 million as of June 30, 2017 is due in the fiscal quarter ending December 31, 2019. 

90 

 
The Credit Facility requires the Company to maintain an interest expense coverage ratio as described in the Credit 
Agreement, on a quarterly basis, covering the trailing four consecutive fiscal quarters of no less than 3.50 to 1.00. In addition, 
the Company is required to maintain the maximum leverage ratio as described in the Credit Agreement on a quarterly basis 
of 3.00 to 1.00, covering the trailing four consecutive fiscal quarters for each fiscal quarter. 

The Company was in compliance with the financial covenants under the Credit Agreement as of June 30, 2017 and had 

no outstanding borrowings under the unfunded revolving credit facility.  

Debt Redemption:  

In December 2014, the Company redeemed the $750.0 million aggregate principal amount of the 2018 Senior Notes. 
The  redemption  resulted  in  a  pre-tax  net  loss  on  extinguishment  of  debt  of  $131.7  million  for  the  three  months  ended 
December 31, 2014 after an offset of a $1.2 million gain upon the termination of the non-designated forward contract entered 
by  the  Company  in  November  2014.  The  objective  of  entering  into  the  non-designated  forward  contract  was  to  lock  the 
treasury rate used to determine the redemption amount of the 2018 Senior Notes. The notional amount of the non-designated 
forward contract was $750.0 million. Refer to Note 16, “Derivative Instruments and Hedging Activities.” 

NOTE 8 — EQUITY AND LONG-TERM INCENTIVE COMPENSATION PLANS 

Equity Incentive Program 

As of June 30, 2017, the Company had two plans under which the Company was able to issue equity incentive awards, 
such as restricted stock units and stock options, to its employees, consultants and members of its Board of Directors: the 2004 
Equity Incentive Plan (the “2004 Plan”) and the 1998 Director Plan (the “Outside Director Plan”).  

2004 Plan:  

The 2004 Plan provides for the grant of options to purchase shares of the Company’s common stock, stock appreciation 
rights, restricted stock units, performance shares, performance units and deferred stock units to the Company’s employees, 
consultants and members of its Board of Directors. As of June 30, 2017, 3.1 million shares were available for issuance under 
the 2004 Plan.  

Any 2004 Plan awards of restricted stock units, performance shares, performance units or deferred stock units with a 
per share or unit purchase price lower than 100% of fair market value on the grant date are counted against the total number 
of shares issuable under the 2004 Plan as follows, based on the grant date of the applicable award: (a) for any such awards 
granted before November 6, 2013, the awards counted against the 2004 Plan share reserve as 1.8 shares for every one share 
subject thereto; and (b) for any such awards granted on or after November 6, 2013, the awards count against the 2004 Plan 
share reserve as 2.0 shares for every one share subject thereto. 

In addition, the plan administrator has the ability to grant “dividend equivalent” rights in connection with awards of 
restricted stock units, performance shares, performance units and deferred stock units before they are fully vested. The plan 
administrator, at its discretion, may grant a right to receive dividends on the aforementioned awards which may be settled in 
cash or Company stock at the discretion of the plan administrator subject to meeting the vesting requirement of the underlying 
awards. 

91 

 
 
 
Outside Director Plan     

The Outside Director Plan only permits the issuance of stock options to the non-employee members of the Board of 

Directors. As of June 30, 2017, 1.7 million shares were available for grant under the Outside Director Plan.

The number of restricted stock units reflects the application of the award multiplier as described above (1.8x or 2.0x
depending on the grant date of the applicable award). 

Represents the portion of  shares listed as “Options canceled/expired/forfeited” above that were issued under the
Company’s equity incentive plans other than the 2004 Plan and the Outside Director Plan. Because the Company is
only  currently  authorized  to  issue  equity  awards under  the  2004  Plan  and  the Outside Director  Plan, any  equity
awards  that  are  canceled,  expired  or  forfeited  under  any  other  Company  equity  incentive  plan  do  not  result  in
additional shares being available to the Company for future grant. 

Includes restricted stock units granted to senior management with performance-based vesting criteria (in addition to
service-based vesting  criteria  for  any of  such restricted  stock units  that are deemed  to  have been  earned). As of
June 30, 2017, it had not yet been determined the extent to which (if at all) the performance-based vesting criteria 
had been satisfied. Therefore, this line item includes all performance-based restricted stock units granted during the
fiscal year, reported at the maximum possible number of shares that may ultimately be issuable if all applicable
performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully 
satisfied (84 thousand shares, 0.7 million shares and 0.6 million shares for the fiscal years ended June 30, 2017,
2016 and 2015, respectively, after application of the 1.8x or 2.0x multiplier described above).  

During  the  fiscal  year  ended  June  30,  2015,  the  Company  adjusted  the  number  of  shares  subject  to  outstanding 
options under the 2004 Plan by an aggregate of 4,245 shares pursuant to a proportionate and equitable adjustment
for the effect of the special cash dividend, as required by the 2004 Plan. The total number of outstanding options
under the 2004 Plan as well as the associated exercise prices were adjusted to ensure the aggregate intrinsic value
remained the same after considering the effect of the special cash dividend. As the adjustment was required by the
2004  Plan,  under  the  authoritative  guidance,  the  adjustment  to  the  outstanding  awards  did  not  result  in  any

92 

 
   
 
 
 
 
 
  
 
  
 
  
incremental compensation expense. Additionally, the adjustment did not have an impact on the shares available for
future issuance under the 2004 Plan. 

The fair value of stock-based awards is measured at the grant date and is recognized as an expense over the employee’s 
requisite service period. For restricted stock units granted without “dividend equivalent” rights, fair value is calculated using 
the closing price of the Company’s common stock on the grant date, adjusted to exclude the present value of dividends which 
are not accrued on those restricted stock units. The fair value for restricted stock units granted with “dividend equivalent” 
rights is determined using the closing price of the Company’s common stock on the grant date. As of June 30, 2017, the 
Company  accrued  $13.8  million  of  dividends  payable,  which  included  both  a  special  cash  dividend  and  quarterly  cash 
dividends for the unvested restricted stock units outstanding as of the dividend record date. The fair value for purchase rights 
under the Company’s Employee Stock Purchase Plan is determined using a Black-Scholes valuation model.

the first quarter of its fiscal year ended June 30, 2017, the Company recorded excess tax benefits in the provision for income 
taxes of $6.6 million. See Note 1, “Description of Business and Summary of Significant Accounting Policies” for additional

Share numbers reflect actual shares subject to awarded restricted stock units. As described above, under the terms of
the 2004 Plan, the number of shares subject to each award reflected in this number is multiplied by either 1.8x or 2.0x
(depending on the grant date of the award) to calculate the impact of the award on the share reserve under the 2004
Plan. 

Includes restricted stock units granted to senior management with performance-based vesting criteria (in addition to
service-based vesting criteria for any of such restricted stock units that are deemed to have been earned). As of June 30, 
2017, it had not yet been determined the extent to which (if at all) the performance-based vesting criteria had been
satisfied.  Therefore,  this  line  item  includes  all  performance-based  restricted  stock  units,  reported  at  the  maximum
possible number of shares (i.e., 42 thousand shares the fiscal years ended June 30, 2017 and 0.3 million shares for each
of the fiscal years ended June 30, 2016 and 2015) that may ultimately be issuable if all applicable performance-based 
criteria are achieved at their maximum and all applicable service-based criteria are fully satisfied. 

The restricted stock units granted by the Company generally vest (a) with respect to awards with only service-based 
vesting criteria, in three or four equal installments and (b) with respect to awards with both performance-based and service-
based vesting criteria, in two equal installments on the third and fourth anniversaries of the grant date, in each case subject to 
the recipient remaining employed by the Company as of the applicable vesting date. The restricted stock units granted to the 
independent members of the board of directors vest on the first anniversary of the date of grant.  

The following table shows the weighted-average grant date fair value per unit for the restricted stock units granted and

As of June 30, 2017, the unrecognized stock-based compensation expense balance related to restricted stock units was 
$99.4  million,  excluding  the  impact  of  estimated  forfeitures,  and  will  be  recognized  over  a  weighted-average  remaining 
contractual  term  and  an  estimated  weighted-average  amortization  period  of  1.4  years.  The  intrinsic  value  of  outstanding 
restricted stock units as of June 30, 2017 was $205.1 million. 

Cash-Based Long-Term Incentive Compensation 

 The Company has adopted a cash-based long-term incentive (“Cash LTI”) program for many of its employees as part 
of the Company’s employee compensation program. During the fiscal years ended June 30, 2017 and 2016, the Company 
approved Cash LTI awards of $96.7 million and $49.3 million, respectively, under the Company’s Cash Long-Term Incentive 
Plan (“Cash  LTI  Plan”).  Cash  LTI  awards issued  to employees under  the  Cash LTI  Plan will  vest  in  three  or four equal 
installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each anniversary of the 
grant date over a three or four-year period. In order to receive payments under a Cash LTI award, participants must remain 
employed by the Company as of the applicable award vesting date. Executives and non-employee Board members are not 
participating in this program. During the fiscal years ended June 30, 2017, 2016 and 2015, the Company recognized $48.8 
million, $44.6 million and $39.6 million, respectively, in compensation expense under the Cash LTI Plan. As of June 30, 
2017, the unrecognized compensation balance (excluding the impact of estimated forfeitures) related to the Cash LTI Plan 
was $127.7 million.

Employee Stock Purchase Plan 

KLA-Tencor’s Employee Stock Purchase Plan (“ESPP”) provides that eligible employees may contribute up to 10% of 
their  eligible  earnings  toward  the  semi-annual  purchase  of  KLA-Tencor’s  common  stock.  The  ESPP  is  qualified  under 
Section 423 of the Internal Revenue Code. The employee’s purchase price is derived from a formula based on the closing 
price of the common stock on the first day of the offering period versus the closing price on the date of purchase (or, if not a 
trading day, on the immediately preceding trading day). 

The offering period (or length of the look-back period) under the ESPP has a duration of six months, and the purchase 
price with respect to each offering period beginning on or after such date is, until otherwise amended, equal to 85% of the 
lesser of (i) the fair market value of the Company’s common stock at the commencement of the applicable six-month offering 
period or (ii) the fair market value of the Company’s common stock on the purchase date. The Company estimates the fair 
value of purchase rights under the ESPP using a Black-Scholes valuation model.  

The fair value of each purchase right under the ESPP was estimated on the date of grant using the Black-Scholes option 

valuation model and the straight-line attribution approach with the following weighted-average assumptions:

The ESPP shares are replenished annually on the first day of each fiscal year by virtue of an evergreen provision. The 
provision allows for share replenishment equal to the lesser of 2.0 million shares or the number of shares which KLA-Tencor 
estimates will be required to be issued under the ESPP during the forthcoming fiscal year. As of June 30, 2017, a total of 684 
thousand shares were reserved and available for issuance under the ESPP. 

Quarterly cash dividends 

On May 4, 2017, the Company’s Board of Directors declared a regular quarterly cash dividend of $0.54 per share on 
the outstanding shares of the Company’s common stock, which was paid on June 1, 2017 to the stockholders of record as of 
the close of business on May 15, 2017. The total amount of regular quarterly cash dividends paid by the Company during the 
fiscal  years  ended  June  30, 2017  and 2016 was  $335.4  million  and  $324.5  million,  respectively.  The  amount of  accrued

$4.8 million and $2.7 million as of June 30, 2017 and 2016, respectively. These amounts will be paid upon vesting of the 
underlying restricted stock units. Refer to Note 19, “Subsequent Events” for additional information regarding the declaration 
of the quarterly cash divided announced subsequent to June 30, 2017. 

Special cash dividend 

On November 19, 2014, the Company’s Board of Directors declared a special cash dividend of $16.50 per share, which 
was paid on December 9, 2014 to the stockholders of record as of the close of business on December 1, 2014. Additionally, 
in connection with the special cash dividend, the Company’s Board of Directors and the Compensation Committee of the 
Board of Directors approved a proportionate and equitable adjustment to outstanding equity awards (restricted stock units 
and stock options), as required under the 2004 Plan, subject to the vesting requirements of the underlying awards. As the 
adjustment  was  required  by  the  2004  Plan,  the  adjustment  to  the  outstanding  awards  did  not  result  in  any  incremental 
compensation  expense  due  to  modification  of  such  awards,  under  the  authoritative  guidance.  Under  the  authoritative 
guidance, the dividend when declared is recognized as a reduction of retained earnings, to the extent available, with any 
shortfall recognized as a reduction of additional paid-in-capital. The special cash dividend reduced the retained earnings by 
$2.11 billion as of the special cash dividend declaration date, reducing the retained earnings amount to zero and the excess 
amount of the special cash dividend of $646.5 million was charged against additional paid-in capital. The declaration and 
payment  of  the  special  cash dividend  were part  of  the  Company’s  leveraged recapitalization  transaction under which  the 
special cash dividend was financed through a combination of existing cash and proceeds from the debt financing disclosed 
in Note 7, “Debt” that was completed during the three months ended December 31, 2014. The total amount of the special 
cash dividend accrued by the Company during the three months ended December 31, 2014 was approximately $2.76 billion, 
substantially all of which was paid out during the three months ended December 31, 2014, except for the aggregate special 
cash dividend of $43.0 million that was accrued for the unvested restricted stock units. As of June 30, 2017 and 2016, the 
Company  had  a  total  of  $9.0  million  and  $16.9  million,  respectively,  of  accrued  dividends  payable  for  the  special  cash 
dividend  with  respect  to  outstanding  unvested  restricted  stock  units,  which  will  be  paid  when  such  underlying  unvested 
restricted stock units vest. The Company paid a special cash dividend with respect to vested restricted stock units during the 
fiscal years ended June 30, 2017 and 2016 of $8.6 million and $21.8 million respectively. Other than the special cash dividend 
declared during the three months ended December 31, 2014, the Company historically has not declared any special cash 
dividend.  

NOTE 9 — STOCK REPURCHASE PROGRAM 

The Company’s Board of Directors has authorized a program for the Company to repurchase shares of the Company’s 
common stock. The intent of this program is to offset the dilution from KLA-Tencor’s equity incentive plans and employee 
stock purchase plan, as well as to return excess cash to the Company’s stockholders. Subject to market conditions, applicable 
legal requirements and other factors, the repurchases were made in the open market in compliance with applicable securities 
laws, including the Securities Exchange Act of 1934 and the rules promulgated thereunder such as Rule 10b-18. As of June 30, 
2017,  an  aggregate  of  approximately  5.7  million  shares  were  available  for  repurchase  under  the  Company’s  repurchase 
program.  

Share repurchases for the indicated periods (based on the trade date of the applicable repurchase) were as follows:

NOTE 10 — NET INCOME PER SHARE 

Basic net income per share is calculated by dividing net income available to common stockholders by the weighted-
average number of common shares outstanding during the period. Diluted net income per share is calculated by using the 
weighted-average number of common shares outstanding during the period, increased to include the number of additional 
shares  of  common  stock  that  would  have  been  outstanding  if  the  shares  of  common  stock  underlying  the  Company’s 
outstanding dilutive restricted stock units and stock options had been issued. The dilutive effect of outstanding restricted 
stock units and options is reflected in diluted net income per share by application of the treasury stock method.  

The following table sets forth the computation of basic and diluted net income per share:

KLA-Tencor has a profit sharing program for eligible employees, which distributes, on a quarterly basis, a percentage 
of the Company’s pre-tax profits. In addition, the Company has an employee savings plan that qualifies as a deferred salary 
arrangement under Section 401(k) of the Internal Revenue Code. Since April 1, 2011, the employer match amount was 50% 
of the first $8,000 of an eligible employee’s contribution (i.e., a maximum of $4,000) during each fiscal year.  

The total expenses under the profit sharing and 401(k) programs aggregated $15.3 million, $15.3 million and $14.2 
million in the fiscal years ended June 30, 2017, 2016 and 2015, respectively. The Company has no defined benefit plans in 
the  United  States.  In  addition  to  the  profit  sharing  plan  and  the  United  States  401(k),  several  of  the  Company’s  foreign 
subsidiaries have retirement plans for their full-time employees, several of which are defined benefit plans. Consistent with 
the requirements of local law, the Company deposits funds for certain of these plans with insurance companies, with third-
party  trustees  or  into  government-managed  accounts  and/or  accrues  for  the  unfunded  portion  of  the  obligation.  The 
assumptions used in calculating the obligation for the foreign plans depend on the local economic environment. 

The Company applies authoritative guidance that requires an employer to recognize the funded status of each of its 
defined pension and post-retirement benefit plans as a net asset or liability on its balance sheets. Additionally, the authoritative 
guidance requires an employer to measure the funded status of each of its plans as of the date of its year-end statement of 
financial position. The benefit obligations and related assets under the Company’s plans have been measured as of June 30, 
2017 and 2016.

expectations of future returns relevant to the country in which each plan is in effect and the investments applicable to the 
corresponding plan. The discount rate for each plan was derived by reference to appropriate benchmark yields on high quality 
corporate bonds, allowing for the approximate duration of both plan obligations and the relevant benchmark index.

Fair Value of Plan Assets 

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction 
between market participants at the measurement date. The three levels of inputs used to measure fair value of plan assets are 
described in Note 2, “Fair Value Measurements.” 

The foreign plans’ investments are managed by third-party trustees consistent with the regulations or market practice 
of the country where the assets are invested. The Company is not actively involved in the investment strategy, nor does it 
have control over the target allocation of these investments. These investments made up 100% of total foreign plan assets in 
the fiscal years ended June 30, 2017 and 2016.

The expected aggregate employer contribution for the foreign plans during the fiscal year ending June 30, 2018 is $2.1 

million. 

The total benefits to be paid from the foreign pension plans are not expected to exceed $3.0 million in any year through 

the fiscal year ending June 30, 2027. 

Foreign plan assets measured at fair value on a recurring basis consisted of the following investment categories as of

Concentration of Risk 

The Company manages a variety of risks, including market, credit and liquidity risks, across its plan assets through its 
investment  managers.  The  Company  defines  a  concentration  of  risk  as  an  undiversified  exposure  to  one  of  the  above-
mentioned risks that increases the exposure of the loss of plan assets unnecessarily. The Company monitors exposure to such 
risks in the foreign plans by monitoring the magnitude of the risk in each plan and diversifying the Company’s exposure to 
such  risks  across  a  variety  of  instruments,  markets  and  counterparties.  As  of  June  30,  2017,  the  Company  did  not  have 
concentrations of plan asset investment risk in any single entity, manager, counterparty, sector, industry or country.

As of June 30, 2017, the Company had U.S. federal, state and foreign net operating loss (“NOL”) carry-forwards of 
approximately $29.4 million, $49.4 million and $41.9 million, respectively. The U.S. federal NOL carry-forwards will expire 
at various dates beginning in 2023 through 2029. The utilization of NOLs created by acquired companies is subject to annual 
limitations under Section 382 of the Internal Revenue Code. However, it is not expected that such annual limitation will 
significantly impair the realization of these NOLs. The state NOLs will begin to expire in 2018. State credits of $167.6 million 
will be carried over indefinitely. The foreign NOL carry-forwards will begin to expire in 2018.

The net deferred tax asset valuation allowance was $120.7 million and $105.0 million as of June 30, 2017 and June 30, 
2016,  respectively.  The  change  was  primarily  due  to  an  increase  in  the  valuation  allowance  related  to  state  credit  carry-
forwards generated in the fiscal year ended June 30, 2017. The valuation allowance is based on the Company’s assessment 
that it is more likely than not that certain deferred tax assets will not be realized in the foreseeable future. Of the valuation 
allowance as of June 30, 2017, $103.8 million relates to state credit carry-forwards. The remainder of the valuation allowance 
relates primarily to state and foreign NOL carry-forwards. 

 As of June 30, 2017, U.S. income taxes were not provided for on a cumulative total of approximately $2.60 billion of 
undistributed earnings for certain non-U.S. subsidiaries. If these undistributed earnings were repatriated to the United States, 
they would generate foreign tax credits to reduce the federal tax liability associated with the foreign dividend. Assuming full 
utilization  of  the  foreign  tax  credits,  the  potential  deferred  tax  liability  associated  with  undistributed  earnings  would  be 
approximately $866.0 million. 

KLA-Tencor benefits from tax holidays in Israel and Singapore where it manufactures certain of its products. These tax 
holidays are on approved investments and are scheduled to expire at varying times in the next one to four years. The Company 
was in compliance with all the terms and conditions of the tax holidays as of June 30, 2017. The net impact of these tax 
holidays was to decrease the Company’s tax expense by approximately $32.6 million, $19.5 million and $20.4 million in the 
fiscal years ended June 30, 2017, 2016 and 2015, respectively. The benefits of the tax holidays on diluted net income per 
share were $0.21, $0.12 and $0.13 for the fiscal years ended June 30, 2017, 2016 and 2015, respectively. 

One of the Company’s Singapore holidays is scheduled to expire in August 2018.  The Company is unsure if the holiday 
will be extended.  The Company’s tax rate on income earned under this holiday would increase from 5% to 17% if the holiday 
is not extended.

The amount of unrecognized tax benefits that would impact the effective tax rate was $68.4 million, $50.4 million and 
$69.0 million as of June 30, 2017, 2016 and 2015 respectively. The amount of interest and penalties recognized during the 
years ended June 30, 2017, 2016, and 2015 was expense of $2.2 million, income of $4.3 million as a result of a release of 
unrecognized tax benefits, and expense of $1.2 million, respectively. KLA-Tencor’s policy is to include interest and penalties 
related to unrecognized tax benefits within other expense (income), net. The amount of interest and penalties accrued as of 
June 30, 2017 and 2016 was approximately $5.9 million and $3.7 million, respectively. 

The Company is subject to federal income tax examinations for all years beginning from the fiscal year ended June 30, 
2014. The Company is subject to state income tax examinations for all years beginning from the fiscal year ended June 30, 
2013. The Company is also subject to examinations in other major foreign jurisdictions, including Singapore, for all years 
beginning from the fiscal year ended June 30, 2013. The Company is under income tax examination in Israel for the fiscal 
years ended June 30, 2013 through June 30, 2015. The Company believes that adequate amounts have been reserved for any 
adjustments that may ultimately result from any future examinations of these years.  

It is possible that certain examinations may be concluded in the next twelve months. The Company believes it is possible 
that it may recognize up to $15.3 million of its existing unrecognized tax benefits within the next 12 months as a result of the 
lapse of statutes of limitations and the resolution of examinations with various tax authorities. 

NOTE 13 — COMMITMENTS AND CONTINGENCIES 

Employee  Retention  Commitments.  In  connection  with  the  retention  program  adopted  at  the  time  the  Company 
entered into the Merger Agreement with Lam Research, the Company has an estimated $20.8 million of employee-related 
retention commitments as of June 30, 2017 which are expected to be paid during the quarter ending December 31, 2017. 

Factoring. KLA-Tencor has agreements (referred to as “factoring agreements”) with financial institutions to sell certain 
of its trade receivables and promissory notes from customers without recourse. The Company does not believe it is at risk for 
any material losses as a result of these agreements. In addition, the Company periodically sells certain letters of credit (“LCs”), 
without recourse, received from customers in payment for goods and services. 

The following table shows total receivables sold under factoring agreements and proceeds from sales of LCs for the 

indicated periods:

Facilities. KLA-Tencor leases certain of its facilities under arrangements that are accounted for as operating leases. 
Rent  expense  was  $9.6  million,  $8.7  million  and  $9.1  million  for  the  fiscal  years  ended  June  30,  2017,  2016  and  2015,

Purchase Commitments. KLA-Tencor maintains commitments to purchase inventory from its suppliers as well as 
goods  and  services  in  the  ordinary  course  of  business.  The  Company’s  liability  under  these  purchase  commitments  is 
generally restricted to a forecasted time-horizon as mutually agreed upon between the parties. This forecasted time-horizon 
can  vary  among  different  suppliers.  The  Company’s  estimate  of  its  significant  purchase  commitments  is  approximately 
$432.8 million as of June 30, 2017 which are primarily due within the next 12 months. Actual expenditures will vary based 
upon the volume of the transactions and length of contractual service provided. In addition, the amounts paid under these 
arrangements may be less in the event that the arrangements are renegotiated or canceled. Certain agreements provide for 
potential cancellation penalties. 

Cash Long-Term Incentive Plan. As of June 30, 2017, the Company had committed $163.1 million for future payment 
obligations under its Cash LTI Plan. The calculation of compensation expense related to the Cash LTI Plan includes estimated 
forfeiture rate assumptions. Cash LTI awards issued to employees under the Cash LTI Plan vest in to three or four equal 
installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each yearly anniversary 
of the grant date over a three or four-year period. In order to receive payments under a Cash LTI award, participants must 
remain employed by the Company as of the applicable award vesting date.  

Warranties, Guarantees and Contingencies. KLA-Tencor provides standard warranty coverage on its systems for 40 
hours per week for 12 months, providing labor and parts necessary to repair and maintain the systems during the warranty 
period. The Company accounts for the estimated warranty cost as a charge to costs of revenues when revenue is recognized. 
The estimated warranty cost is based on historical product performance and field expenses. Utilizing actual service records, 
the Company calculates the average service hours and parts expense per system and applies the actual labor and overhead 
rates to determine the estimated warranty charge. The Company updates these estimated charges on a regular basis. The actual 
product performance and/or field expense profiles may differ, and in those cases the Company adjusts its warranty accruals 
accordingly.

The Company maintains guarantee arrangements available through various financial institutions for up to $25.3 million, 
of which $22.1 million had been issued as of June 30, 2017, primarily to fund guarantees to customs authorities for value-
added tax (“VAT”) and other operating requirements of the Company’s subsidiaries in Europe and Asia.  

KLA-Tencor is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party 
with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the 
sale of assets, under which the Company customarily agrees to hold the other party harmless against losses arising from, or 
provides  customers  with  other  remedies  to  protect  against,  bodily  injury  or  damage  to  personal  property  caused  by  the 
Company’s  products,  non-compliance  with  the  Company’s  product  performance  specifications,  infringement  by  the 
Company’s  products  of  third-party  intellectual  property  rights  and  a  breach  of  warranties,  representations  and  covenants 
related to matters such as title to assets sold, validity of certain intellectual property rights, non-infringement of third-party 
rights, and certain income tax-related matters. In each of these circumstances, payment by the Company is typically subject 
to the other party making a claim to and cooperating with the Company pursuant to the procedures specified in the particular 
contract.  

This usually allows the Company to challenge the other party’s claims or, in case of breach of intellectual property 
representations or covenants, to control the defense or settlement of any third-party claims brought against the other party. 
Further, the Company’s obligations under these agreements may be limited in terms of amounts, activity (typically at the 
Company’s option to replace or correct the products or terminate the agreement with a refund to the other party), and duration. 
In some instances, the Company may have recourse against third parties and/or insurance covering certain payments made 
by the Company.  

Subject  to  certain  limitations,  the  Company  is  obligated  to  indemnify  its  current  and  former  directors,  officers  and 
employees  with  respect  to  certain  litigation  matters  and  investigations  that  arise  in  connection  with  their  service  to  the 
Company.  These  obligations  arise  under  the  terms  of  the  Company’s  certificate  of  incorporation,  its  bylaws,  applicable 
contracts, and Delaware and California law. The obligation to indemnify generally means that the Company is required to 
pay or reimburse the individuals’ reasonable legal expenses and possibly damages and other liabilities incurred in connection 
with these matters. 

In  addition,  the  Company  may  in  limited  circumstances  enter  into  agreements  that  contain  customer-specific 
commitments on pricing, tool reliability, spare parts stocking levels, response time and other commitments. Furthermore, the 
Company  may  give  these  customers  limited  audit  or  inspection  rights  to  enable  them  to  confirm  that  the  Company  is 
complying  with  these  commitments.  If  a  customer  elects  to  exercise  its  audit  or  inspection  rights,  the  Company  may  be 
required to expend significant resources to support the audit or inspection, as well as to defend or settle any dispute with a 
customer that could potentially arise out of such audit or inspection. To date, the Company has made no significant accruals 
in  its  consolidated  financial  statements  for  this  contingency.  While  the  Company  has  not  in  the  past  incurred  significant 
expenses for resolving disputes regarding these types of commitments, the Company cannot make any assurance that it will 
not incur any such liabilities in the future. 

105 

 
   
   
       
 
  
  
 
 
It is not possible to predict the maximum potential amount of future payments under these or similar agreements due 
to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular 
agreement.  Historically,  payments  made  by  the  Company  under  these  agreements  have  not  had  a  material  effect  on  its 
business, financial condition, results of operations or cash flows. 

NOTE 14 — LITIGATION AND OTHER LEGAL MATTERS 

Litigation Related to Terminated Merger with Lam Research. 

In  connection  with  the  previously  announced  Merger  transaction  with  Lam  Research,  four  purported  KLA-Tencor 
stockholders filed putative class actions on behalf of all KLA-Tencor stockholders. In January 2017, all four actions were 
dismissed with prejudice. 

Other Legal Matters. 

The Company is named from time to time as a party to lawsuits and other types of legal proceedings and claims in the 
normal course of its business. Actions filed against the Company include commercial, intellectual property, customer, and 
labor and employment related claims, including complaints of alleged wrongful termination and potential class action lawsuits 
regarding alleged violations of federal and state wage and hour and other laws. In general, legal proceedings and claims, 
regardless  of  their  merit,  and  associated  internal  investigations  (especially  those  relating  to  intellectual  property  or 
confidential information disputes) are often expensive to prosecute, defend or conduct and may divert management’s attention 
and other company resources. Moreover, the results of legal proceedings are difficult to predict, and the costs incurred in 
litigation can be substantial, regardless of outcome. The Company believes the amounts provided in its consolidated financial 
statements are adequate in light of the probable and estimated liabilities. However, because such matters are subject to many 
uncertainties, the ultimate outcomes are not predictable, and there can be no assurances that the actual amounts required to 
satisfy  alleged  liabilities  from  the  matters  described  above  will  not  exceed  the  amounts  reflected  in  the  Company’s 
consolidated financial statements or will not have a material adverse effect on its results of operations, financial condition or 
cash flows. 

NOTE 15 — RESTRUCTURING CHARGES 

The Company has in recent years undertaken a number of cost reduction activities, including workforce reductions, in 
an effort to lower its ongoing expense run rate. The program in the United States is accounted for in accordance with the 
authoritative guidance related to compensation for non-retirement post-employment benefits, whereas the programs in the 
Company’s international locations are accounted for in accordance with the authoritative guidance for contingencies.  

During the fourth quarter of fiscal year ended 2015, the Company implemented a plan to reduce its global employee 
workforce  to  streamline  the  organization  and  business  processes  in  response  to  changing  customer  requirements  in  the 
industry. The goals of this reduction were to enable continued innovation, direct the Company’s resources toward its best 
opportunities and lower its ongoing expense run rate. The Company substantially completed its global workforce reduction 
during the fiscal year ended June 30, 2016. Restructuring charges for the year ended June 30, 2016 were $8.9 million, of 
which $3.6 million was recorded to costs of revenues, $1.6 million to research and development expense and $3.7 million to 
selling, general and administrative expense lines of the consolidated statements of operations. Restructuring charges for the 
year ended June 30, 2015 were $31.6 million, of which $8.0 million was recorded to costs of revenues, $11.1 million to 
research and development expense and $12.5 million to selling, general and administrative expense lines of the consolidated 
statements of operations.

NOTE 16 — DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES 

The authoritative guidance requires companies to recognize all derivative instruments and hedging activities, including 
foreign currency exchange contracts, as either assets or liabilities at fair value on the balance sheet. Changes in the fair value 
of derivatives that do not qualify for hedge treatment, as well as the ineffective portion of any hedges, are recognized in other 
expense (income), net in the consolidated statements of operations. In accordance with the guidance, the Company designates 
foreign  currency  forward  exchange  and  option  contracts  as  cash  flow  hedges  of  certain  forecasted  foreign  currency 
denominated sales and purchase transactions. 

KLA-Tencor’s  foreign  subsidiaries  operate  and  sell  KLA-Tencor’s  products  in  various  global  markets.  As  a  result, 
KLA-Tencor is exposed to risks relating to changes in foreign currency exchange rates. KLA-Tencor utilizes foreign currency 
forward exchange contracts and option contracts to hedge against future movements in foreign exchange rates that affect 
certain existing and forecasted foreign currency denominated sales and purchase transactions, such as the Japanese yen, the 
euro,  the  New  Taiwan  dollar  and  the  Israeli  new  shekel.  The  Company  routinely  hedges  its  exposures  to  certain  foreign 
currencies  with  various  financial  institutions  in  an  effort  to  minimize  the  impact  of  certain  currency  exchange  rate 
fluctuations.  These  currency  forward  exchange  contracts  and  options,  designated  as  cash  flow  hedges,  generally  have 
maturities of less than 18 months. Cash flow hedges are evaluated for effectiveness monthly, based on changes in total fair 
value of the derivatives. If a financial counterparty to any of the Company’s hedging arrangements experiences financial 
difficulties or is otherwise unable to honor the terms of the foreign currency hedge, the Company may experience material 
losses. 

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gains or 
losses  on  the  derivative  is  reported  as  a  component  of  accumulated  other  comprehensive  income  (loss)  (“OCI”)  and 
reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the 
fair value of currency forward exchange and option contracts due to changes in time value are excluded from the assessment 
of effectiveness. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded 
from the assessment of effectiveness are recognized in current earnings. 

For derivative instruments that are not designated as accounting hedges, gains and losses are recognized in other expense 
(income), net. The Company uses foreign currency forward contracts to hedge certain foreign currency denominated assets 
or liabilities. The gains and losses on these derivatives are largely offset by the changes in the fair value of the assets or 
liabilities being hedged. 

In  October 2014,  in  anticipation of  the  issuance  of  the  Senior Notes,  the  Company  entered  into  a  series  of forward 
contracts (“Rate Lock Agreements”) to lock the benchmark rate on a portion of the Senior Notes. The objective of the Rate 
Lock Agreements was to hedge the risk associated with the variability in interest rates due to the changes in the benchmark 
rate leading up to the closing of the intended financing, on the notional amount being hedged. The Rate Lock Agreements 
had a notional amount of $1.00 billion in aggregate which matured in the second quarter of the fiscal year ended June 30, 
2015. The Company designated each of the Rate Lock Agreements as a qualifying hedging instrument and accounted for as 
a cash flow hedge, under which the effective portion of the gain or loss on the close out of the Rate Lock Agreements was 
107 

 
   
   
       
       
 
  
  
  
 
initially  recognized  in  accumulated  other  comprehensive  income  (loss)  as  a  reduction  of  total  stockholders’  equity  and 
subsequently amortized into earnings as a component of interest expense over the term of the underlying debt. The ineffective 
portion, if any, was recognized in earnings immediately. The Rate Lock Agreements were terminated on the date of pricing 
of the $1.25 billion of 4.650% Senior Notes due in 2024 and the Company recorded the fair value of $7.5 million as a gain 
within accumulated other comprehensive income (loss) as of December 31, 2014. For the fiscal years ended June 30, 2017, 
2016 and 2015, the Company recognized $0.8 million, $0.8 million and $0.5 million, respectively, for the amortization of the 
gain  recognized  in  accumulated  other  comprehensive  income  (loss),  which  amount  reduced  the  interest  expense.  As  of 
June 30, 2017, the unamortized portion of the fair value of the forward contracts for the rate lock agreements was $5.5 million. 
The cash proceeds of $7.5 million from the settlement of the Rate Lock Agreements were included in the cash flows from 
operating activities in the consolidated statements of cash flows for the fiscal year ended June 30, 2015 because the designated 
hedged item was classified as interest expense in the cash flows from operating activities in the consolidated statements of 
cash flows. 

In addition, in November 2014, the Company entered into a non-designated forward contract to lock the treasury rate 
used to determine the redemption amount of the 2018 Senior Notes. The objective of the forward contract was to hedge the 
risk associated with the variability of the redemption amount due to changes in interest rates through the redemption of the 
existing  2018  Senior  Notes.  The  forward  contract  had  a  notional  amount  of  $750.0  million.  The  forward  contract  was 
terminated in December 2014 and the resulting fair value of $1.2 million was included in the loss on extinguishment of debt 
and other, net line in the consolidated statements of operations, partially offsetting the loss on redemption of the debt during 
the three months ended December 31, 2014. The cash proceeds from the forward contract were included in the cash flows 
from  financing  activities  in  the  consolidated  statements  of  cash  flows  for  the  fiscal  year  ended  June  30,  2015,  partially 
offsetting the cash outflows for the redemption of the 2018 Senior Notes.

NOTE 17 — SEGMENT REPORTING AND GEOGRAPHIC INFORMATION 

KLA-Tencor  reports  one  reportable  segment  in  accordance  with  the  provisions  of  the  authoritative  guidance  for 
segment reporting. Operating segments are defined as components of an enterprise about which separate financial information 
is  evaluated  regularly  by  the  chief  operating  decision  maker  in  deciding  how  to  allocate  resources  and  in  assessing 
performance.  KLA-Tencor’s  chief  operating  decision  maker  is  its  Chief  Executive  Officer.  The  Company  is  engaged 
primarily in designing, manufacturing and marketing process control and yield management solutions for the semiconductor 
and related nanoelectronics industries. 

 All operating segments have been aggregated due to their inter-dependencies, commonality of long-term economic 
characteristics, products and services, the production processes, class of customer and distribution processes. The Company’s 
service products are an extension of the system product portfolio and provide customers with spare parts and fab management 
services (including system preventive maintenance and optimization services) to improve yield, increase production uptime 
and throughput, and lower the cost of ownership. Since the Company operates in one reportable segment, all financial segment 
information required by the authoritative guidance can be found in the consolidated financial statements. 

The Company’s significant operations outside the United States include manufacturing facilities in China, Germany, 
Israel and Singapore and sales, marketing and service offices in Japan, the rest of the Asia Pacific region and Europe. For 
geographical revenue reporting, revenues are attributed to the geographic location in which the customer is located. Long-
lived assets consist of land, property and equipment, net and are attributed to the geographic region in which they are located.

NOTE 18 — RELATED PARTY TRANSACTIONS 

During the fiscal years ended June 30, 2017, 2016 and 2015, the Company purchased from, or sold to, several entities, 
where one or more executive officers of the Company or members of the Company’s Board of Directors, or their immediate 
family  members  were,  during  the  periods  presented,  an  executive  officer  or  a  board  member  or  a  board  member  of  a 
subsidiary,  including  Broadcom  Limited,  Cisco  Systems,  Inc.,  Citrix  Systems,  Inc.,  Juniper  Networks,  Inc.,  Keysight 
Technologies,  Inc.,  MetLife,  and  NetApp,  Inc.  The  following  table  provides  the  transactions  with  these  parties  for  the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of KLA-Tencor Corporation: 

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in 
all material respects, the financial position of KLA-Tencor Corporation and its subsidiaries at June 30, 2017 and June 30, 
2016, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 2017 in 
conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the 
financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the 
information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, 
the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2017 based 
on  criteria  established  in  Internal  Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission  (COSO).  The  Company’s  management  is  responsible  for  these  financial 
statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal 
Control  over  Financial  Reporting  appearing  under  Item  9A.  Our  responsibility  is  to  express  opinions  on  these  financial 
statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our 
integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about 
whether  the  financial  statements  are  free  of  material  misstatement  and  whether  effective  internal  control  over  financial 
reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and 
significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing 
the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control 
based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions. 

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

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

ITEM  9A. 

CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures 

The Company conducted an evaluation of the effectiveness of the design and operation of its disclosure controls and 
procedures  (as  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the 
“Exchange Act”)) (“Disclosure Controls”) as of the end of the period covered by this Annual Report on Form 10-K (this 
“Report”)  required  by  Exchange  Act  Rules  13a-15(b)  or  15d-15(b).  The  controls  evaluation  was  conducted  under  the 
supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer 
(“CEO”) and Chief Financial Officer (“CFO”). Based on this evaluation, the CEO and CFO have concluded that as of the 
end of the period covered by this Report the Company’s Disclosure Controls were effective at a reasonable assurance level. 

Attached as exhibits to this Report are certifications of the CEO and CFO, which are required in accordance with Rule 
13a-14  of  the  Exchange  Act.  This  Controls  and  Procedures  section  includes  the  information  concerning  the  controls 
evaluation referred to in the certifications, and it should be read in conjunction with the certifications for a more complete 
understanding of the topics presented. 

Definition of Disclosure Controls 

Disclosure Controls are controls and procedures designed to reasonably assure that information required to be disclosed 
in the Company’s reports filed under the Exchange Act, such as this Report, is recorded, processed, summarized and reported 
within the time periods specified in the SEC’s rules and forms. Disclosure Controls are also designed to reasonably assure 
that such information is accumulated and communicated to the Company’s management, including the CEO and CFO, as 
appropriate to allow timely decisions regarding required disclosure. The Company’s Disclosure Controls include components 
of its internal control over financial reporting, which consists of control processes designed to provide reasonable assurance 
regarding the reliability of its financial reporting and the preparation of financial statements in accordance with generally 
accepted accounting principles in the United States. To the extent that components of the Company’s internal control over 
financial  reporting  are  included  within  its  Disclosure  Controls,  they  are  included  in  the  scope  of  the  Company’s  annual 
controls evaluation. 

Management’s Report on Internal Control over Financial Reporting 

The Company’s management is responsible for establishing and maintaining adequate internal control over financial 
reporting  as  defined  in  Rules  13a-15(f)  and  15d-15(f)  under  the  Exchange  Act.  Under  the  supervision  and  with  the 
participation of the Company’s management, including the CEO and CFO, the Company conducted an evaluation of the 
effectiveness  of  its  internal  control  over  financial  reporting  based  on  criteria  established  in  the  framework  in  Internal 
Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 
Based on this evaluation, the Company’s management concluded that the Company’s internal control over financial reporting 
was effective as of June 30, 2017. 

The effectiveness of the Company’s internal control over financial reporting as of June 30, 2017 has been audited by 
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in 
Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K. 

114 

 
 
 
 
Limitations on the Effectiveness of Controls 

The Company’s management, including the CEO and CFO, does not expect that the Company’s Disclosure Controls or 
internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed 
and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, 
the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be 
considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can 
provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. 
These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can 
occur  because  of  simple  error  or  mistake.  Controls  can  also  be  circumvented  by  the  individual  acts  of  some  persons,  by 
collusion of two or more people, or by management override of the controls. The design of any system of controls is based 
in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed 
in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of 
changes  in  conditions  or  deterioration  in  the  degree  of  compliance  with  policies  or  procedures.  Because  of  the  inherent 
limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. 

Changes in Internal Control over Financial Reporting 

There were no changes in the Company’s internal control over financial reporting that occurred during the fourth quarter 
of fiscal year 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control 
over financial reporting.
