Cover: Glass is remarkably versatile. To date, scientists have combined silica with approximately 
50 elements to develop unique glass compositions. But we have the potential to use the entire  
Periodic  Table  in  countless  combinations.  To  drive  that  point  home,  imagine  you’re  holding  
an  Oxford  English  Dictionary  in  your  hands  and  think  of  how  many  words  we  can  make  using  
only 26 letters. That’s why we believe some of the greatest glass innovations are still ahead.

Corning is one of the world’s 
leading innovators in materials 
science. For more than 165 years, 
Corning has applied its unparalleled 
expertise in specialty glass, ceramics, 
and optical physics to develop products 
that have created new industries 
and transformed people’s lives.

To Our Shareholders:

Corning  marked  its  165th  birthday  in  2016.  When  you  are 
at  the  helm  of  an  institution  that  spans  three  centuries, 
you  learn  to  take  the  long  view.  That  means  rewarding 
shareholders in the near term, while protecting the interests 
of  all  stakeholders  long  term.  It  means  optimizing  today’s 
businesses,  while  investing  to  create  tomorrow’s  growth 
drivers.  And  it  means  making  strategic  choices  to  ensure 
sustainable  success  and  ongoing  relevance  in  an  evolving 
and highly competitive global marketplace. 

That’s  exactly  what  Corning’s  Management  Committee   
was  doing  when  it  laid  out  the  company’s  Strategy  and 
Capital Allocation Framework in late 2015. (Details follow.)

Stakeholders’  assessment  of  Corning’s  2016  performance 
will depend on their vantage point. An examination of the 
year’s  financial  results  reveals  core  sales  that  were  down 
slightly  from  2015.  A  broader  view  shows  a  company  that 
strengthened  its  industry  leadership  and  ended  the  year 
strong.  And  the  long  view  reveals  strong  progress  toward 
the targets Corning said it would achieve within a four-year 
period. 

Although  2016  was  not  a  growth  year  for  us,  we  were          
extremely  pleased  with  several  key  achievements.  We 
strengthened  Corning’s  portfolio  with  strategic  transac-
tions.  We  advanced  major  innovation  programs.  And  we   
returned cash to shareholders through stock buybacks and 
a double-digit dividend increase. As we look ahead, we are 
confident in Corning’s ability to deliver sustainable secular 
growth over the long term.

2016 Financial Results

Before I review our execution against the Framework, here’s 
a closer look at Corning’s financial performance. 

Core  sales  were  $9.7  billion,  down  1  percent  from  2015, 
while core earnings were $1.8 billion, down approximately                    
6  percent  year  over  year.  However,  core  earnings  per  share 
of  $1.55  were  up  11  percent  from  2015,  driven  by  share 
repurchases  as  part  of  our  strategy  to  create  value  for 
investors.

The first quarter was our weakest, driven by a combination  
of slow demand in some markets and a short-term execution 
issue. We told investors our performance would improve as 
the year progressed, and we delivered on that commitment 
with strong year-over-year growth in the second half. 

n 

n 

In Display Technologies, volume was up despite a matur-
ing market for LCD televisions and lower-than-expected 
demand in the IT segment. Core sales were down year 
over year due to price declines, which exceeded volume 
growth.  However,  price  declines  were  more  moderate 
than in 2015, and Corning continues to lead competitors 
on sales and profitability by a wide margin.

In  Optical  Communications,  strong  demand  for  fiber-
to-the-home  technology  was  offset  by  problems  with 
a manufacturing software implementation early in the 
year. We  resolved  the  issue  in  the  second  quarter  and 
believe  that  the  sales  growth  in  the  third  and  fourth 
quarters reflects the true strength of this segment.

n  Specialty Materials sales were lower than expected due 
to  weakness  in  the  smartphone  and  tablet  markets. 
However,  the  year  finished  strong,  driven  by  the 
introduction of new products in the Corning® Gorilla® 
Glass family.

n 

In Environmental Technologies, record sales of automo-
tive emissions-control products beat expectations and 
offset anticipated slow sales of products for heavy-duty 
applications in North America and China.  

n  Life  Sciences  sales  were  up,  driven  by  growth  in  the 

bioprocess segment and in Greater China.  

Our Strategy and Capital Allocation Framework

I  described  Corning’s  Strategy  and  Capital  Allocation 
Framework  in  my  last  letter,  but  here’s  a  quick  recap.  The 
Framework  articulates  Corning’s  plan  for  leveraging  its 
financial strength and focusing its portfolio to deliver  value 
over the next several years.

Utilizing Our Financial Strength

We expect to generate and deploy $26 – $30 billion through 
2019.  We  will  invest  $10  billion  to  grow  and  sustain  our 
leadership. We also plan to distribute more than $12.5 billion 
to our shareholders through share repurchases and annual 
dividend  increases  of  at  least  10  percent.  Note  that  we 
increased this distribution target from our original plan of 
$10 billion, which underscores our confidence in Corning’s 
future operating cash flows. 

Focusing Our Portfolio

The Framework focuses our portfolio on a set of reinforcing 
capabilities  with  strong  inter-connections.  Our  best-in-
the-world  capabilities  include  three  core  technologies 
(glass  science,  ceramics  science,  and  optical  physics), 
four  manufacturing  and  engineering  platforms  (vapor 
deposition,  fusion,  extrusion,  and  precision  forming),  and 
five  market-access  platforms  (optical  communications, 
display,  mobile  consumer  electronics,  automotive,  and 
life  sciences  vessels). We  direct  80  percent  or  more  of  our 
resources to opportunities that draw from at least two of 
these  capabilities  sets.  We  believe  this  approach  reduces 
the cost of innovation, increases our likelihood of success, 
and creates higher barriers to entry for our competitors.

Focusing  our  portfolio  also  means  we  will  make  strategic 
acquisitions that enhance our product portfolio or increase 
our market reach, as well as divestitures that deliver value 
for shareholders. 

The  Framework  underscores  our  commitment  to  good 
capital stewardship, while also honoring our commitment 
to  life-changing  innovation.  However,  we  follow  Winston 
Churchill’s  sage  advice:  “However  beautiful  the  strategy, 
you  should  occasionally  look  at  the  results.”  We  have 
been  closely  measuring  our  progress  and  providing 
regular  updates  to  investors  so  they  can  assess  Corning’s 
performance and outlook for themselves. 

Since  introducing  the  Framework  in  late  2015,  we  have 
distributed  more  than  $6  billion  to  shareholders  through 
share  repurchases  and  a  12.5  percent  increase  to  our 
quarterly  dividend.  We  also  announced  a  new  $4  billion 
share  repurchase  authorization  in  December  2016  and  a 
14.8  percent  dividend  increase  in  February  2017  as  part  of 
our ongoing commitment to reward our investors. 

Turning  to  our  portfolio,  we  realigned  our  interest  in  Dow 
Corning,  which  creates  significant  value  for  shareholders, 
including unlocking $4.8 billion in cash. We strengthened  our 
position in Optical Communications with the acquisitions of 
Alliance Fiber Optic Products, Inc. and STRAN Technologies. 
We  also  entered  into  a  joint  venture  with  Saint-Gobain 
Sekurit to develop automotive glazing solutions and seeded 
a startup, Versalume, to commercialize our Fibrance® light-
diffusing fiber in a range of industries.  

On  the  innovation  front,  we  launched  new  products  and 
gained traction with customers on key growth initiatives.

n  We  expanded  our  cover-glass  portfolio  with  Gorilla® 
Glass 5, which offers superior drop performance versus 
its predecessor and competitive technologies; Gorilla® 
Glass  SR+  for  wearable  devices;  and  Vibrant  Gorilla® 
Glass, which enables high-resolution designs for smart-
phones, tablets, and notebooks.

n  Corning Iris™ Glass was named a “Display Component    
of the Year” by the Society for Information Display.

the-world  capabilities  include  three  core  technologies 
(glass  science,  ceramics  science,  and  optical  physics),

Sekurit to develop automotive glazing solutions and seeded 
a startup, Versalume, to commercialize our Fibrance® light-
diffusing fiber in a range of industries.  

n  We have won the majority of platforms to date for gas 

particulate filters. 

n  And  we  continue  to  expand  the  opportunities  for 
Gorilla  Glass  in  the  automotive  market.  Our  first 
windshield,  sunroof,  and  backlite  windows  went  into 
series  production,  and  we  have  been  selected  for 
multiple  auto  interior  jobs. The  2016  Paris  Auto  Show 
featured a curved Gorilla Glass console and instrument 
panel,  and  our  Gorilla  Glass-enabled  concept  car  was 
lauded as one of the highlights of the 2017 Consumer 
Electronics Show.

The  Framework  has  paid  off  from  a  shareholder  perspec-
tive, as well. Between October 2015 (when we introduced 
the  Framework)  and  December  2016,  Corning  returned  
50  percent  versus  13.8  percent  for  the  S&P  500  (both  
dividend adjusted).

On  the  innovation  front,  we  launched  new  products  and 
gained traction with customers on key growth initiatives.

Opportunities Ahead

n  We  expanded  our  cover-glass  portfolio  with  Gorilla® 
Glass 5, which offers superior drop performance versus 
its predecessor and competitive technologies; Gorilla® 
Glass  SR+  for  wearable  devices;  and  Vibrant  Gorilla® 
Glass, which enables high-resolution designs for smart-
phones, tablets, and notebooks.

n  Corning Iris™ Glass was named a “Display Component    
of the Year” by the Society for Information Display.

As we look to 2017 and beyond, here are some of the ways 
we are exploiting our distinctive capabilities to create new 
revenue generators.

n 

In  Display  Technologies,  we’re  leveraging  our  fusion 
assets,  glass  science,  and  optical  physics  capabilities 
to  drive  the  next  round  of  display  innovations  (better 
images,  ubiquitous  touch,  flexible  displays,  thinner 
form factors) so we can continue creating and capturing 
value as the LCD industry matures.

In  Optical  Communications,  we  expect  significant 
growth  as  we  continue  innovating  for  rapidly  evolving 
applications,  such  as  fiber  to  the  home,  wireless 
technology, and data centers.

The  mobile  consumer  electronics  market  remains  a 
key focus for our Specialty Materials segment. We will 
continue  innovating  to  increase  scratch  resistance, 
improve  drop  durability,  enhance  optical  clarity,  and 
enable new form factors. 

n  Corning  is  well  positioned  to  benefit  from  the 
automotive  industry’s  trend  toward  cleaner,  safer, 
and  more  connected  cars.  The  adoption  of  gasoline 
particulate  filters  for  gasoline  direct-injection  engines 
has  the  potential  to  increase  our  sales  opportunity 
in  our 
per  vehicle  by  a  factor  of  three-to-four 
Environmental  Technologies  segment.  We’re  also 
pursuing  opportunities  for  Gorilla  Glass  to  reduce 
vehicle  weight,  improve  damage  resistance,  increase 
interactivity, and add aesthetic appeal.

n 

Life  Sciences  growth  will  be  driven  by  bioprocessing, 
cell  therapy,  and  3D  cell  culture.  Our  Pharmaceutical 
Technologies business is also poised to capture an excit-
ing opportunity for next-generation glass packaging for 
drug storage and delivery.

We  are  excited  to  have  such  rich  growth  opportunities 
in  diverse  markets,  and  we  believe  that  these  initiatives 

position us to resume growth in the medium term. Will they 
all succeed? Probably not, but we are confident that many 
will.  And  because  we  are  leveraging  existing  capabilities 
and  resources  to  capture  these  opportunities,  we  reduce 
the  cost  of  our  innovation  investments,  creating  a  very 
attractive risk/reward ratio.    

Living in the Glass Age

The  demand  for  advanced  glass  will  continue  to  grow  as 
more industries recognize its unique aesthetic and technical 
attributes. Last year, I told you that Corning believes we’ve 
entered a new era that can best be described as The Glass 
Age.  Several  factors  led  us  to  that  declaration,  including 
the ubiquity of glass and its central role in our day-to-day 
lives, the increasing relevance of glass to a broad range of 
industries, and  the  accelerating  pace  of  glass  innovation. 
Recent developments lend credence to our claim. 

Corning  has  helped  bring  to  life  many  of  the  products 
that we envisioned in our 2011 video A Day Made of Glass, 
including  infotainment  walls,  digital  fitting  rooms,  and 
connected cars. More and more of today’s leading innovators 
are  recognizing  the  potential  of  glass  to  solve  some  of 
their toughest problems, which is reflected in the diversity 
of  the  companies  who  approach  us  and  the  enthusiastic 
response  we  received  at  the  Consumer  Electronics  Show.  
Additionally,  the  International  Journal  of  Applied  Glass 
Science recently published a special issue titled “The Glass 
Age,” featuring contributions from universities and research 

institutions  across  the  globe  on  today’s  most  cutting-
edge  glass  research,  including  technologies  to  enhance 
healthcare,  explore  planetary  and  geological  phenomena, 
and augment reality. Taken in sum, this work reinforces the 
fact that glass is not only one of the most transformative 
materials in history, but also has the potential to solve some 
of our world’s most urgent challenges in the future.

Corning  is  excited  to  be  leading  the  effort  to  enhance 
people’s  lives  with  advanced  glass  technologies,  and  we 
believe  that  some  of  the  greatest  glass  innovations  still       
lie ahead.

Closing Thoughts

I  began  my  letter  by  talking  about  the  long  view.  I’ll  end  
with an example of what that looks like in action. More than  
four  decades  ago,  Corning  invented  low-loss  optical  fiber 
and ushered in a communications revolution. Today, almost 
3 billion kilometers of optical fiber are deployed worldwide, 
and  a  single  optical  fiber  link  can  carry  up  to  10  terabits 
per second — enough to stream 2 million high-definition 
videos simultaneously. In 2016, Corning won a Technical and 
Engineering  Emmy®  Award  for  this  pioneering  invention 
and its continued impact on the broadcasting industry.

That’s the kind of innovation we do at Corning — inventions 
that  transform  industries  and  unleash  significant  new 
capabilities.  Our  style  of  innovation  also  delivers  long-
term  value  for  Corning  and  its  shareholders.  Using  glass

response  we  received  at  the  Consumer  Electronics  Show.  
Additionally,  the  International  Journal  of  Applied  Glass 
Science recently published a special issue titled “The Glass 
Age,” featuring contributions from universities and research 

institutions  across  the  globe  on  today’s  most  cutting-
edge  glass  research,  including  technologies  to  enhance 
healthcare,  explore  planetary  and  geological  phenomena, 
and augment reality. Taken in sum, this work reinforces the 
fact that glass is not only one of the most transformative 
materials in history, but also has the potential to solve some 
of our world’s most urgent challenges in the future.

Corning  is  excited  to  be  leading  the  effort  to  enhance 
people’s  lives  with  advanced  glass  technologies,  and  we 
believe  that  some  of  the  greatest  glass  innovations  still       
lie ahead.

Closing Thoughts

I  began  my  letter  by  talking  about  the  long  view.  I’ll  end  
with an example of what that looks like in action. More than  
four  decades  ago,  Corning  invented  low-loss  optical  fiber 
and ushered in a communications revolution. Today, almost 
3 billion kilometers of optical fiber are deployed worldwide, 
and  a  single  optical  fiber  link  can  carry  up  to  10  terabits 
per second — enough to stream 2 million high-definition 
videos simultaneously. In 2016, Corning won a Technical and 
Engineering  Emmy®  Award  for  this  pioneering  invention 
and its continued impact on the broadcasting industry.

science, ceramics science, and optical physics — along with 
our expertise in vapor deposition, extrusion, and precision 
forming — we have continually increased the performance, 
lowered the cost, and improved the installation of optical 
networks. This has allowed us to capture a disproportionate 
share  of  the  profits  versus  our  competitors.  And  by 
leveraging  our  best-in-the-world  capabilities,  we  believe  
we  can  grow  our  Optical  Communications  segment  at 
more than double the rate of the overall industry.

Innovation done our way isn’t easy. It isn’t always fast. And 
it’s  hard  to  predict  the  ultimate  timing  and  returns.  But  I 
believe it’s worth it, because our successes have a profound 
impact on the world and create value for decades. 

Corning  has  a  165-year  track  record  of  life-changing 
innovation,  and  we  are  committed  to  another  165  years.     
You can count on us to manage through challenges, deliver 
on our commitments, and communicate our progress along   
the way.

Sincerely,

That’s the kind of innovation we do at Corning — inventions 
that  transform  industries  and  unleash  significant  new 
capabilities.  Our  style  of  innovation  also  delivers  long-
term  value  for  Corning  and  its  shareholders.  Using  glass

pitch  variation,  resulting  in  brighter,  more  energy-efficient  displays 
with  higher  resolutions  for  consumers  and  better  yields  for  panel 
makers.

Through  the  end  of  2013,  the  Display  Technologies  segment  also 
included  the  equity  affiliate  Samsung  Corning  Precision  Materials  Co., 
Ltd. (“Samsung Corning Precision Materials”), of which Corning owned 
57.5% and Samsung Display Co., Ltd. (“Samsung Display”) owned 42.5%. 
As  described  more  fully  in  Note  8  (Acquisitions)  to  the  Consolidated 
Financial Statements,  to extend Corning’s leadership in specialty glass 
and drive earnings growth, Corning entered into a series of strategic and 
financial  agreements  with  Samsung  Display  intended  to  strengthen 
product  and  technology  collaborations  between  the  two  companies. 
Corning  completed  the  acquisition  of  Samsung  Corning  Precision

All  other  segments  that  do  not  meet  the  quantitative  threshold 
for  separate  reporting  have  been  grouped  as  “All  Other.”  This  group 
is  primarily  comprised  of  the  results  of  Corning’s  Pharmaceutical 
Technologies  business,  our  non-LCD  glass  business,  new  product  lines 
and development projects, as well as certain corporate investments such 
as Eurokera and Keraglass equity affiliates. 

The All Other segment represented 2% of Corning’s sales in 2016.

Additional  explanation  regarding  Corning  and  its  five  reportable 
segments,  as  well  as  financial  information  about  geographic  areas, 
is  presented  in  Management’s  Discussion  and  Analysis  of  Financial 
Condition and Results of Operations and Note 20 (Reportable Segments) 
to the Consolidated Financial Statements.

Prior  to  realignment,  HSG,  a  consolidated  subsidiary  of  Dow  Corning, 
was an indirect equity investment of Corning. Upon completion of the 
exchange, Corning now has a direct equity investment in HSG. Because 
our  ownership  percentage  in  HSG  did  not  change  as  a  result  of  the 
realignment,  the  investment  in  HSG  is  recorded  at  its  carrying  value, 
which had a negative carrying value of $383 million at the transaction 
date.  The  negative  carrying  value  resulted  from  a  one-time  charge  to 
this  entity  in  2014  for  the  permanent  abandonment  of  certain  assets. 
Excluding this charge, the entity is profitable and is expected to recover 
its equity in the near term.

CORNING INCORPORATED - 2016 Annual ReportBusiness Description

Pittsburgh  Corning  Corporation�  Prior  to  the  second  quarter  of  2016, 
Corning  and  PPG  Industries,  Inc.  each  owned  50%  of  the  capital  stock 
of  Pittsburgh  Corning  Corporation  (“PCC”).  PCC  filed  for  Chapter  11 
reorganization  in  2000  and  the  Modified  Third  Amended  Plan  of 
Reorganization  for  PCC  (the “Plan”)  became  effective  in  April  2016.  In 
the  second  quarter  of  2016,  Corning  contributed  its  equity  interests 

in PCC and Pittsburgh Corning Europe N.V. as required by the Plan and 
recognized a gain of $56 million for the difference between the fair value 
of the asbestos litigation liability and carrying value of the investment. 

Additional  information  about  corporate  investments  is  presented  in 
Note 7 (Investments) to the Consolidated Financial Statements.

Competition

Corning  competes  with  many  large  and  varied  manufacturers,  both 
domestic and foreign. Some of these competitors are larger than Corning, 
and  some  have  broader  product  lines.  Corning  strives  to  maintain 
and  improve  its  market  position  through  technology  and  product 
innovation.  For  the  future,  Corning  believes  its  competitive  advantage 
lies in its commitment to research and development, its commitment to 
reliability of supply and product quality and technical specification of its 
products. There is no assurance that Corning will be able to maintain or 
improve its market position or competitive advantage.

Display Technologies Segment
We believe Corning is the largest worldwide producer of glass substrates 
for  LCD  displays. The  environment  for  LCD  glass  substrate  products  is 
very competitive and Corning believes it has sustained its competitive 
advantages  by  investing  in  new  products,  providing  a  consistent 
and  reliable  supply,  and  continually  improving  its  proprietary  fusion 
manufacturing  process. This  process  allows  us  to  deliver  glass  that  is 
larger, thinner and lighter, with exceptional surface quality and without 
heavy metals. Asahi Glass Co. Ltd. and Nippon Electric Glass Co. Ltd. are 
Corning’s principal competitors in display glass substrates.

Optical Communications Segment
Corning  believes  it  maintains  a  leadership  position  in  the  segment’s 
principal product groups, which include carrier and enterprise networks. 
The  competitive 
industry  consolidation,  price 
includes 
pressure  and  competition  for  the  innovation  of  new  products.  These 
competitive  conditions  are  likely  to  persist.  Corning  believes  its  large 
scale  manufacturing  experience,  fiber  process,  technology  leadership 
and intellectual property provide cost advantages relative to several of 
its competitors. 

landscape 

The  primary  competing  producers  of  the  Optical  Communications 
segment are Commscope and Prysmian Group. 

Raw Materials

Corning’s  manufacturing  processes  and  products  require  access  to 
uninterrupted power sources, significant quantities of industrial water, 
certain  precious  metals,  and  various  batch  materials.  Availability  of 
resources  (ores,  minerals,  polymers,  helium  and  processed  chemicals) 
required in manufacturing operations, appears to be adequate. Corning’s 
suppliers, from time to time, may experience capacity limitations in their 
own operations, or may eliminate certain product lines. Corning believes 
it has adequate programs to ensure a reliable supply of raw and batch 
materials  as  well  as  precious  metals.  For  many  products,  Corning  has 
alternate  suppliers  that  would  allow  operations  to  continue  without 
interruption in the event of specific materials shortages.

Environmental Technologies Segment
Corning  believes  it  maintains  a  leadership  position  in  the  worldwide 
automotive  ceramic  substrate  products,  and  a  strong  presence  in  the 
heavy-duty and light-duty diesel vehicle market. The Company believes 
its  competitive  advantage  in  automotive  ceramic  substrate  products 
for  catalytic  converters  and  diesel  filter  products  for  exhaust  systems 
is  based  upon  global  presence,  customer  service,  engineering  design 
services and product innovation. Corning’s Environmental Technologies 
products face principal competition from NGK Insulators, Ltd. and Ibiden 
Co. Ltd.

Specialty Materials Segment
Corning  has  deep  capabilities  in  materials  science,  optical  design, 
shaping, coating, finishing, metrology, and system assembly. Additionally, 
we are addressing emerging needs of the consumer electronics industry 
with  the  development  of  chemically  strengthened  glass.  Corning 
Gorilla  Glass  is  a  thin-sheet  glass  that  is  better  able  to  survive  events 
that  most  commonly  cause  glass  failure.  Its  advanced  composition 
allows  a  deeper  layer  of  chemical  strengthening  than  is  possible  with 
most  other  chemically  strengthened  glasses,  making  it  both  durable 
and  damage  resistant.  Our  products  and  capabilities  in  this  segment 
position  the  Company  to  meet  the  needs  of  a  broad  array  of  markets 
including display, semiconductor, aerospace/defense, astronomy, vision 
care, industrial/commercial, and telecommunications. For this segment, 
Schott, Asahi Glass Co. Ltd., Nippon Electric Glass Co. Ltd. and Heraeus are 
the main competitors.

Life Sciences Segment
Corning  seeks  to  maintain  a  competitive  advantage  by  emphasizing 
product  quality,  global  distribution,  supply  chain  efficiency,  a  broad 
product  line  and  superior  product  attributes.  Our  principle  worldwide 
competitors  include  Thermo  Fisher  Scientific,  Inc.,  Greiner  Group  AG, 
Eppendorf AG and Sarsedt AG. Corning also faces increasing competition 
from  large  distributors  that  have  pursued  backward  integration  or 
introduced private label products.

Certain  key  materials  and  proprietary  equipment  used 
in  the 
manufacturing of products are currently sole-sourced or available only 
from a limited number of suppliers.  To minimize this risk, Corning closely 
monitors  raw  materials  and  equipment  with  limited  availability  or 
which are sourced through one supplier.  However, any future difficulty 
in  obtaining  sufficient  and  timely  delivery  of  components  and/or  raw 
materials could result in lost sales due to delays or reductions in product 
shipments, or reductions in Corning’s gross margins.

Protection of the Environment

Corning has a program to ensure that its facilities are in compliance with 
state,  federal  and  foreign  pollution-control  regulations.  This  program 
has  resulted  in  capital  and  operating  expenditures  each  year.  In  order 
to maintain compliance with such regulations, capital expenditures for 
pollution control in operations were approximately $14 million in 2016 
and are estimated to be $31 million in 2017.

Corning’s  2016  consolidated  operating  results  were  charged  with 
approximately  $43  million  for  depreciation,  maintenance,  waste 
disposal  and  other  operating  expenses  associated  with  pollution 
control. Corning believes that its compliance program will not place it at 
a competitive disadvantage.

environments that present numerous risks, many of which are driven by 
factors that we cannot control or predict. Our operations and financial 
results  are  subject  to  various  risks  and  uncertainties,  including  those 
described  below,  that  could  adversely  affect  our  business,  financial 
condition,  results  of  operations,  cash  flows,  our  ability  to  successfully 
execute our strategy and capital allocation framework, and the trading 
price  of  our  common  stock  or  debt.  The  following  discussion  of  “risk 
factors”  identifies  the  most  significant  factors  that  may  adversely 
affect  our  business,  operations,  financial  position  or  future  financial 
performance.  This  information  should  be  read  in  conjunction  with 
MD&A  and  the  consolidated  financial  statements  and  related  notes 
incorporated  by  reference  into  this  report. The  following  discussion  of

include  data  privacy  requirements,  employment  and 
laws, 
tax  laws,  anti-competition  regulations,  prohibitions  on  payments 
to  governmental  officials,  import  and  trade  restrictions  and  export 
requirements.  Non-compliance  or  violations  could  result  in  fines, 
criminal  sanctions  against  us,  our  officers  or  our  employees,  and 
prohibitions on the conduct of our business. Such violations could result 
in prohibitions on our ability  to offer our products and services in one 
or  more  countries  and  could  also  materially  damage  our  reputation, 
our brand, our international expansion efforts, our ability to attract and 
retain  employees,  our  business  and  our  operating  results.  Our  success 
depends, in part, on our ability to anticipate and manage these risks.

CORNING INCORPORATED - 2016 Annual ReportRisk Factors

We  are  also  subject  to  a  variety  of  other  risks  in  managing  a  global 
organization, including those related to:

• Difficulty in collecting obligations owed to us;

• Natural  disasters  such  as  floods,  earthquakes,  tsunamis  and 

• The economic and political conditions in each country or region;

windstorms; and

• Complex  regulatory  requirements  affecting  international  trade  and 
investment, including anti-dumping laws, export controls, the Foreign 
Corrupt  Practices  Act  and  local  laws  prohibiting  improper  payments. 
Our operations may be adversely affected by changes in the substance 
or  enforcement  of  these  regulatory  requirements,  and  by  actual  or 
alleged violations of them;

• Fluctuations in currency exchange rates, convertibility of currencies and 
restrictions  involving  the  movement  of  funds  between  jurisdictions 
and countries; 

• Sovereign  and  political  risks  that  may  adversely  affect  Corning’s 

profitability and assets;

• Geographical  concentration  of  our  factories  and  operations,  and 

regional shifts in our customer base;

• Periodic health epidemic concerns;

• Political unrest, confiscation or expropriation of our assets by foreign 

governments, terrorism and the potential for other hostilities; 

• Difficulty in protecting intellectual property, sensitive commercial and 

operations data, and information technology systems;

• Differing  legal  systems,  including  protection  and  treatment  of 

intellectual property and patents;

• Complex, or competing tax regimes; 

• Tariffs,  trade  duties  and  other  trade  barriers  including  anti-dumping 

duties;

• Potential loss of utilities or other disruption affecting manufacturing.

Corning’s Display Technologies segment generates a significant amount 
of  the  Company’s  profits  and  cash  flow�  Any  significant  decrease  in 
LCD  glass  pricing  could  have  a  material  and  negative  impact  on  our 
financial results

Corning’s  ability  to  generate  profits  and  operating  cash  flow  depends 
largely upon the profitability of our LCD glass business, which is subject 
to  continuous  pricing  pressure  due  to  intense  industry  competition, 
potential  over-capacity,  and  development  of  new  technologies.  If  we 
are not able to achieve proportionate reductions in costs or sustain our 
current  rate  of  cost  reduction  to  offset  potential  pricing  pressures  it 
could have a material adverse impact on our financial results.

Because  we  have  a  concentrated  customer  base  in  each  of  our 
businesses,  our  sales  could  be  negatively  impacted  by  the  actions  or 
insolvency of one or more key customers, as well as our ability to retain 
these customers

A relatively small number of customers accounted for a high percentage 
of  net  sales  in  our  reportable  segments.  Mergers  and  consolidations 
between  customers  could  result  in  further  concentration  of  Corning’s 
customer base. If further concentration occurs or a key customer becomes 
insolvent, the loss of a key customer could result in a substantial loss of 
sales and reduction in anticipated in cash flows. Unforeseen events or 
actions on the part of Corning could also result in the loss of customers, 
resulting in further customer concentration.

Business disruptions could affect our operating results 

A significant portion of our manufacturing, research and development 
activities, and certain other critical business operations are concentrated 
in a few geographic areas. A major earthquake, fire or other catastrophic 
event that results in the destruction or disruption of any of our critical 
facilities  could  severely  affect  our  ability  to  conduct  normal  business 
operations  and,  as  a  result,  our  future  financial  results  could  be 
materially  and  adversely  affected.  For  example,  certain  manufacturing 
sites  require  high  quality,  continuous,  and  uninterrupted  power  and 
access  to  industrial  water.  Unplanned  outages  could  have  a  material 
negative impact on our operations and ability to supply our customers. 

Additionally,  a  significant  amount  of  the  specialized  manufacturing 
capacity  for  our  reportable  segments  is  concentrated  in  single-site 
locations  and  it  is  reasonably  possible  that  the  operations  of  one  or 
more such facilities could be disrupted. Due to the specialized nature of 
the assets, it may not be possible to find replacement capacity quickly 
or substitute production from other facilities. Accordingly, a disruption 
at  a  single-site  manufacturing  operation  could  significantly  impact 
Corning’s ability to supply its customers and could produce a near-term 
severe impact on our individual businesses and the Company as a whole.

We  may  experience  difficulties  in  enforcing  our  intellectual  property 
rights, which could result in loss of market share, and we may be subject 
to claims of infringement of the intellectual property rights of others

We  rely  on  patent  and  trade  secret  laws,  copyright,  trademark, 
confidentiality  procedures,  controls  and  contractual  commitments 
to  protect  our  intellectual  property  rights.  Despite  our  efforts,  these 
protections  may  be  limited  and  we  may  encounter  difficulties  in 
protecting  our  intellectual  property  rights  or  obtaining  rights  to 
additional  intellectual  property  necessary  to  permit  us  to  continue  or 
expand our businesses. We cannot provide assurance that the patents 
that we hold or may obtain will provide meaningful protection against our 
competitors. Changes in or enforcement of laws concerning intellectual 
property,  worldwide,  may  affect  our  ability  to  prevent  or  address  the 
misappropriation of, or the unauthorized use of, our intellectual property, 
potentially resulting in loss of market share. Litigation may be necessary 
to  enforce  our  intellectual  property  rights.  Litigation  is  inherently 
uncertain and outcomes are often unpredictable. If we cannot protect 
our intellectual property rights against unauthorized copying or use, or 
other misappropriation, we may not remain competitive.

8

CORNING INCORPORATED - 2016 Annual ReportThe  intellectual  property  rights  of  others  could  inhibit  our  ability  to 
introduce new products. Other companies hold patents on technologies 
used in our industries and are aggressively seeking to expand, enforce 
and license their patent portfolios. We periodically receive notices from, 
or have lawsuits filed against us by third parties claiming infringement, 
misappropriation  or  other  misuse  of  their  intellectual  property  rights 
and/or breach of our agreements with them. These third parties often 
include entities that do not have the capabilities to design, manufacture, 
or distribute products or that acquire intellectual property like patents 
for the sole purpose of monetizing their acquired intellectual property 
through  asserting  claims  of  infringement  and  misuse.  Such  claims 
of  infringement  or  misappropriation  may  result  in  loss  of  revenue, 
substantial  costs,  or  lead  to  monetary  damages  or  injunctive  relief 
against us. 

Information technology dependency and security vulnerabilities could 
lead to reduced revenue, liability claims, or competitive harm

The  Company  is  dependent  on  information  technology  (“IT”)  systems 
and infrastructure for its business and manufacturing controls. Our IT 
systems may be vulnerable to disruptions from human error, outdated 
applications,  computer  viruses,  natural  disasters,  unauthorized  access, 
cyber-attack  and  other  similar  disruptions.  Any  significant  disruption, 
breakdown, intrusion, interruption or corruption of these systems or data 
breaches  could  cause  the  loss  of  data,  equipment  damage,  downtime, 
and/or  safety  related  issues  and  could  have  a  material  adverse  effect 
on  our  business.  Like  other  global  companies,  we  have,  from  time  to 
time, experienced incidents related  to our IT systems, and expect  that 
such  incidents  will  continue,  including  malware  and  computer  virus 
attacks, unauthorized access, systems failures and disruptions. We have 
measures and defenses in place against unauthorized access, but we may 
not be able to prevent, immediately detect, or remediate such events. A 
material breach in the security of our IT systems could include the theft 
of our intellectual property or trade secrets. Such disruptions or security 
breaches could result in the theft, unauthorized use or publication of our 
intellectual property and/or confidential business information, harm our 
competitive position, disrupt our manufacturing, reduce the value of our 
investment in research and development and other strategic initiatives, 
or otherwise adversely affect our business. 

Additionally,  we  believe  that  utilities  and  other  operators  of  critical 
infrastructure  that  serve  our  facilities  face  heightened  security  risks, 
including  cyber-attack.  In  the  event  of  such  an  attack,  disruption  in 
service  from  our  utility  providers  could  disrupt  our  manufacturing 
operations  which  rely  on  a  continuous  source  of  power  (electrical, 
gas, etc.).

We may not earn a positive return from our research, development and 
engineering investments 

Developing our products through our innovation model of research and 
development  is  expensive  and  often  involves  a  long  investment  cycle. 
We  make  significant  expenditures  and  investments  in  research  and 
development and four process engineering platforms that may earn an 
economic  return.  If  our  investments  do  not  provide  a  pipeline  of  new 
technologies that our customers demand or lower cost manufacturing 
platforms,  it  could  negatively  impact  our  revenues  and  operating 
margins both near- and long-term. 

Risk Factors

We  have  significant  exposure  to  foreign  currency  movements  and  to 
counterparties of our related derivatives portfolio 

A  large  portion  of  our  sales,  profit  and  cash  flows  are  transacted  in 
non-U.S. dollar currencies and we expect that we will continue to realize 
gains  or  losses  with  respect  to  these  exposures.  We  also  maintain 
a  significant  portfolio  of  over  the  counter  derivatives  to  hedge  our 
projected  currency  exposure  to  the  Japanese  yen,  New  Taiwan  dollar, 
South Korean won, Chinese yuan and euro. We are exposed to potential 
losses in the event of non-performance by our counterparties to these 
derivative  contracts.  Any  failure  of  a  counterparty  to  pay  on  such  a 
contract  when  due  could  materially  impact  our  results  of  operations, 
financial position, and cash flows.

For  example,  we  will  experience  foreign  currency  gains  and  losses 
in  certain  instances  if  it  is  not  possible  or  cost  effective  to  hedge  our 
currency  exposures  or  should  we  elect  not  to  hedge  certain  currency 
exposures.  Alternatively,  we  may  experience  gains  or  losses  if  the 
underlying  exposure  which  we  have  hedged  change  (increases  or 
decreases)  and  we  are  unable  to  reverse,  unwind,  or  terminate  the 
hedges concurrent with the change in the underlying notional exposure. 

Our ultimate realized loss or gain with respect to currency fluctuations 
will generally depend on the size and type of cross-currency exposures 
that we enter into, the exchange rates associated with these exposures 
and  changes  in  those  rates,  whether  we  have  entered  into  foreign 
currency  contracts  to  offset  these  exposures  and  other  factors.  Our 
hedge portfolio may reduce our flexibility to respond to price moves by 
our Display Technologies segment competitors.

All  of  these  factors  could  materially  impact  our  results  of  operations, 
anticipated future results, financial position and cash flows, the timing 
of which is variable and generally outside of our control.

If we are unable to obtain certain specialized equipment, raw and batch 
materials or natural resources required in our products or processes, our 
business will suffer

Our  ability  to  meet  customer  demand  depends,  in  part,  on  our  ability 
to  obtain  timely  and  adequate  delivery  of  equipment,  parts  and 
components  from  our  suppliers.  We  may  experience  shortages  that 
could adversely affect our operations. There can be no assurances that 
we  will  not  encounter  problems  in  the  future.  Certain  manufacturing 
equipment  and  components  are  available  only  from  single  or  limited 
sources,  and  we  may  not  be  able  to  find  alternate  sources  in  a  timely 
manner.  A  reduction,  interruption  or  delay  of  supply,  or  a  significant 
increase  in  the  price  for  supplies,  such  as  manufacturing  equipment, 
precious metals, raw materials, utilities including energy and industrial 
water, could have a material adverse effect on our businesses.

We  use  specialized  raw  materials  from  single-source  suppliers 
(e.g.,  specific  mines  or  quarries)  and  natural  resources  (e.g.,  helium)  in 
certain  products  and  processes.  If  a  supplier  is  unable  to  provide  the 
required raw materials or the natural resource is in scarce supply or not 
readily available, we may be unable to change our product composition 
or  manufacturing  process  in  order  to  prevent  a  disruption  to  our 
business.

9

CORNING INCORPORATED - 2016 Annual ReportRisk Factors

We  have  incurred,  and  may  in  the  future  incur,  goodwill  and  other 
intangible asset impairment charges

At December 31, 2016, Corning had goodwill and other intangible assets 
of  $2.4  billion.  While  we  believe  the  estimates  and  judgments  about 
future cash flows used in the goodwill impairment tests are reasonable, 
we  cannot  provide  assurance  that  additional  impairment  charges 
in  the  future  will  not  be  required  if  the  expected  cash  flow  estimates 
as  projected  by  management  do  not  occur,  especially  if  an  economic 
recession occurs and continues for a lengthy period or becomes severe, 
or if acquisitions and investments made by the Company fail to achieve 
expected returns.

Changes  in  our  effective  tax  rate  or  tax  liability  may  have  an  adverse 
effect on our results of operations

Our  effective  tax  rate  could  be  adversely  impacted  by  several  factors, 
including:

• Changes in the relative amounts of income before taxes in the various 
jurisdictions  in  which  we  operate  that  have  differing  statutory  tax 
rates;

• Changes in tax laws, tax treaties and regulations or the interpretation 

of them;

• Changes to our assessment about the realizability of our deferred tax 
assets that are based on estimates of our future results, the prudence 
and  feasibility  of  possible  tax  planning  strategies,  and  the  economic 
and political environments in which we do business;

• The  outcome  of  current  and  future  tax  audits,  examinations,  or 

administrative appeals;

• Changes  in  generally  accepted  accounting  principles  that  affect  the 

accounting for taxes; and

• Limitations or adverse findings regarding our ability to do business in 

some jurisdictions.

We may have additional tax liabilities

We are subject to income taxes in the U.S. and many foreign jurisdictions 
and  are  commonly  audited  by  various  tax  authorities.  In  the  ordinary 
course  of  our  business,  there  are  many  transactions  and  calculations 
where  the  ultimate  tax  determination 
is  uncertain.  Significant 
judgment  is  required  in  determining  our  worldwide  provision  for 
income  taxes.  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 effect 
on  our  financial  statements  in  the  period  or  periods  for  which  that 
determination is made.

A  significant  amount  of  our  net  profits  and  cash  flows  are  generated 
from  outside  the  U.S.,  and  certain  repatriation  of  funds  currently  held 
in  foreign  jurisdictions  may  result  in  higher  effective  tax  rates  for  the 
Company.  In  addition,  there  have  been  proposals  to  change  U.S.  tax 
laws  that  could  significantly  impact  how  U.S.  global  corporations  are 
taxed. Although we cannot predict whether or in what form proposed 
legislation may pass, if enacted certain proposals could have a material 
adverse impact on our tax expense and cash flow.

Our  innovation  model  depends  on  our  ability  to  attract  and  retain 
specialized experts in our core technologies

Our innovation model requires us to employ highly specialized experts 
in  glass  science,  ceramic  science,  and  optical  physics  to  conduct  our 
research  and  development  and  engineer  our  products  and  design 
our  manufacturing  facilities.  The  loss  of  the  services  of  any  member 
of  our  key  research  and  development  or  engineering  team  without 
adequate  replacement,  or  the  inability  to  attract  new  qualified 
personnel, could have a material adverse effect on our operations and 
financial performance. 

10

We  are  subject  to  strict  environmental  regulations  and  regulatory 
changes  that  could  result  in  fines  or  restrictions  that  interrupt  our 
operations

Some of our manufacturing processes generate chemical waste, waste 
water, other industrial waste or greenhouse gases, and we are subject to 
numerous laws and regulations relating  to  the use, storage, discharge 
and  disposal  of  such  substances.  We  have  installed  anti-pollution 
equipment  for  the  treatment  of  chemical  waste  and  waste  water  at 
our facilities. We have taken steps to control the amount of greenhouse 
gases  created  by  our  manufacturing  operations.  However,  we  cannot 
provide  assurance  that  environmental  claims  will  not  be  brought 
against us or  that government regulators will not  take steps  to adopt 
more stringent environmental standards.

Any  failure  on  our  part  to  comply  with  any  present  or  future 
environmental regulations could result in the assessment of damages or 
imposition of fines against us, or the suspension/cessation of production 
or operations. In addition, environmental regulations could require us to 
acquire costly equipment, incur other significant compliance expenses 
or  limit  or  restrict  production  or  operations  and  thus  materially  and 
negatively affect our financial condition and results of operations.

Changes in regulations and the regulatory environment in the U.S. and 
other countries, such as those resulting from the regulation and impact 
of  global  warming  and  CO2  abatement,  may  affect  our  businesses 
and their results in adverse ways by, among other things, substantially 
increasing manufacturing costs, limiting availability of scarce resources, 
especially energy, or requiring limitations on production and sale of our 
products or those of our customers.

Current or future litigation or regulatory investigations may harm our 
financial condition or results of operations

As described in Legal Proceedings in this Form 10-K, we are engaged in 
litigation and regulatory matters. Litigation and regulatory proceedings 
may be uncertain, and adverse rulings could occur, resulting in significant 
liabilities, penalties or damages. Such current or future substantial legal 
liabilities or regulatory actions could have a material adverse effect on 
our business, financial condition, cash flows and reputation. 

Our global operations are subject to extensive trade and anti-corruption 
laws and regulations

Due  to  the  international  scope  of  our  operations,  we  are  subject  to  a 
complex  system  of  import-  and  export-related  laws  and  regulations, 
including U.S. regulations issued by Customs and Border Protection, the 
Bureau of Industry and Security, the Office of Anti-boycott Compliance, 
the  Directorate  of  Defense  Trade  Controls  and  the  Office  of  Foreign 
Assets  Control,  as  well  as  the  counterparts  of  these  agencies  in  other 
countries.  Any  alleged  or  actual  violation  by  an  employee  or  the 
Company may subject us to government scrutiny, investigation and civil 
and criminal penalties, and may limit our ability to import or export our 
products  or  to  provide  services  outside  the  United  States. We  cannot 
predict the nature, scope or effect of future regulatory requirements to 
which our operations might be subject or the manner in which existing 
laws might be administered or interpreted.

In  addition,  the  U.S.  Foreign  Corrupt  Practices  Act  and  similar 
foreign  anti-corruption  laws  generally  prohibit  companies  and  their 
intermediaries from making improper payments or providing anything 
of  value  to  improperly  influence  foreign  government  officials  for  the 
purpose  of  obtaining  or  retaining  business,  or  obtaining  an  unfair 
advantage. Recent years have seen a substantial increase in the global 
enforcement  of  anti-corruption  laws.  Our  continued  operation  and 
expansion outside the United States, including in developing countries, 
could increase the risk of alleged violations. Violations of these laws may 
result  in  severe  criminal  or  civil  sanctions,  could  disrupt  our  business, 
and result in an adverse effect on our reputation, business and results of 
operations or financial condition.

CORNING INCORPORATED - 2016 Annual ReportMoreover,  several  of  our  related  partners  are  domiciled  in  areas  of  the 
world with laws, rules and business practices that differ from those in the 
United States, and we face the reputational and legal risk that our related 
partners may violate applicable laws, rules and business practices.

International trade policies may negatively impact our ability to sell and 
manufacture our products outside of the U�S�

Government  policies  on  international  trade  and  investment  such 
as  import  quotas,  tariffs,  and  capital  controls,  whether  adopted  by 
individual governments or addressed by regional trade blocs, can affect 

the  demand  for  our  products  and  services,  impact  the  competitive 
position of our products or prevent us (including our equity affiliates/
joint  ventures)  from  being  able  to  sell  and/or  manufacture  products 
in  certain  countries.  The  implementation  of  more  restrictive  trade 
policies,  such  as  higher  tariffs  or  new  barriers  to  entry,  in  countries  in 
which we sell large quantities of products and services could negatively 
impact  our  business,  results  of  operations  and  financial  condition. 
For  example,  a  government’s  adoption  of  “buy  national”  policies  or 
retaliation  by  another  government  against  such  policies  could  have  a 
negative impact on our results of operations. These policies also affect 
our equity companies. 

Legal Proceedings

Non-PCC  Asbestos  Litigation�  Corning  is  a  defendant  in  cases  alleging 
injuries from asbestos which had been stayed pending the confirmation 
of  the  PCC  Plan. The  stay  was  lifted  on  August  25,  2016.  For  additional 
information and updates to estimated liabilities as of December 31, 2016, 
see Note 7 (Investments) to the Consolidated Financial Statements.

Environmental Litigation� Corning has been named by the Environmental 
Protection  Agency  (the  Agency)  under  the  Superfund  Act,  or  by  state 
governments  under  similar  state  laws,  as  a  potentially  responsible 
party for 17 active hazardous waste sites. Under  the Superfund Act, all 
parties who may have contributed any waste to a hazardous waste site, 
identified by  the Agency, are jointly and severally liable for  the cost of 

cleanup  unless  the  Agency  agrees  otherwise.  It  is  Corning’s  policy  to 
accrue  for  its  estimated  liability  related  to  Superfund  sites  and  other 
environmental liabilities related to property owned by Corning based on 
expert analysis and continual monitoring by both internal and external 
consultants. At December 31, 2016 and December 31, 2015, Corning had 
accrued  approximately  $43  million  (undiscounted)  and  $37  million 
(undiscounted), respectively, for the estimated liability for environmental 
cleanup  and  related  litigation.  Based  upon  the  information  developed 
to date, management believes that the accrued reserve is a reasonable 
estimate of the Company’s liability and that the risk of an additional loss 
in an amount materially higher than that accrued is remote.

(1)  On  October  26,  2015,  Corning’s  Board  of  Directors  authorized  the  repurchase  of  up  to  $4  billion  of  common  stock. This  authorization  was  fully 
utilized in the first quarter of 2017. On December 7, 2016, Corning’s Board of Directors authorized a share repurchase program with no expiration for 
the repurchase of up to $4 billion of common stock (the “2016 Repurchase Program”).

Strategy and Capital Allocation Framework
In October 2015, Corning announced a new strategy and capital allocation 
framework (“the Framework”) that reflects the Company’s financial and 
operational strengths, as well as its ongoing commitment to increasing 
shareholder value. The Framework outlines our leadership priorities, and 
articulates the opportunities we see across our businesses. We designed 
the Framework to create significant value for shareholders by focusing 
our portfolio and leveraging our financial strength. Under our Framework 
we  target  generating  $26  billion  to  $30  billion  of  cash  through  2019, 
returning  more  than  $12.5  billion  to  shareholders  and  investing 
$10 billion to sustain our leadership positions and deliver growth.

Our  probability  of  success  increases  as  we  invest  in  our  world-class 
capabilities.  Over  the  next  three  years,  Corning  will  concentrate 
approximately  80%  of  its  research,  development  and  engineering 
investment  and  capital  spending  on  a  cohesive  set  of  three  core 
technologies,  four  manufacturing  and  engineering  platforms,  and  five 
market-access platforms. This strategy will allow us to quickly apply our 
talents and repurpose our assets as needed.

Performance against the Framework
Since  introducing  the  Framework,  we  have  distributed  approximately 
$6 billion to shareholders through share repurchases and dividends. Our 
Board  also  approved  a  new  $4  billion  share  repurchase  authorization 
in December 2016, and annual dividend increases of 12.5% in 2016 and 
14.8%  in  February  2017  as  part  of  our  ongoing  commitment  to  return 
cash to our investors.

Within  our  portfolio,  we  realigned  our  interest  in  Dow  Corning,  which 
created significant value for shareholders, including unlocking $4.8 billion 
in cash. We strengthened our position in Optical Communications with 
two  acquisitions  to  expand  our  access  to  various  segments  of  the 
telecommunications market. We also entered into a joint venture with 
Saint-Gobain Sekurit to develop automotive glazing solutions.

We also utilized our financial strength in 2016 to continue our focus on 
innovation,  resulting  in  the  launch  of  new  products  and  traction  with 
customers on key growth initiatives, including:

• Gorilla®  Glass  5,  which  offers  superior  drop  performance  versus  its 
predecessor and competitive technologies; expanding our cover-glass 
portfolio with Vibrant® Gorilla® Glass, which enables high-resolution 
designs  for  smartphones,  tablets,  and  notebooks;  and  Gorilla®  Glass 
SR+ for wearable devices.

• Leveraging our competitive advantages and market-leading products 
to  continue  to  win  business  in  the  optical  market,  with  customer 
commitments and demand that support the capacity expansions now 
underway.

• Winning  business  in  the  automotive  sector  for  both  substrates  and 
our new gas particulate filters. We anticipate that our gas particulate 
filters  will  increase  our  sales  opportunity  by  a  factor  of  3-to-4  per 
vehicle.

• Expanding  the  opportunities  for  Corning  Gorilla  Glass 

in  the 

automotive market.

• Technical and commercial progress on Corning Iris™ glass.

2016 Results
Our sales grew in total in 2016 driven by year-over-year growth in most 
of  our  operating  segments.  The  first  quarter  was  our  weakest,  driven 
by  a  combination  of  slow  demand  in  some  markets  and  production 
issues related  to  the implementation of new manufacturing software, 
which constrained our ability to manufacture product. Momentum built 
steadily throughout the year and our performance in the second half of 
2016 was significantly improved from the first half.

Net  sales  in  the  year  ended  December  31,  2016  were  $9,390  million, 
an  increase  of  $279  million,  or  3%,  when  compared  to  the  year  ended 
December  31,  2015.  The  increase  was  primarily  driven  by  the  Display 
Technologies  segment  and  the  Corning  Pharmaceutical  Technologies 
business,  up  $152  million  and  $84  million,  respectively.  The  Optical 
Communications,  Specialty  Materials  and  Life  Sciences  segments  also 
increased, up $25 million, $17 million and $18 million, respectively.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

For  the  year  ended  December  31,  2016,  we  generated  net  income  of 
$3.7  billion,  or  $3.23  per  share,  compared  to  net  income  of  $1.3  billion, 
or $1.00 per share, for 2015. When compared to last year, the $2.4 billion 
increase  in  net  income  was  due  to  the  following  items  (amounts 
presented after tax):

• A $2.7 billion non-taxable gain and $105 million positive tax adjustment 
on the strategic realignment of our ownership interest in Dow Corning 
completed on May 31, 2016;

• The increase in unrealized losses from our foreign currency translation 

hedges in the amount of $47 million.

The translation impact of fluctuations in foreign currency exchange rates 
positively affected Corning’s consolidated net income in the year ended 
December  31,  2016  in  the  amount  of  $229  million  when  compared  to 
2015, largely due to the strengthening of the Japanese yen versus the U.S. 
dollar. This impact was more than offset by the decrease of $283 million 
in the realized gain from our foreign currency translation hedges.

• The  positive  change  in  the  amounts  recorded  for  tax  law  changes, 
valuation  allowance  adjustments  and  other  discrete  tax  items  of 
$104 million; and

• A  decrease  of  $61  million  in  the  defined  benefit  pension  plans 

mark-to-market loss, driven by higher returns on pension assets.

Partially offsetting these events were the following items:

• Lower  net  income  in  the  Display  Technologies,  Specialty  Materials 
and  Life  Sciences  segments. The  largest  decrease  was  in  the  Display 
Technologies  segment,  down  $160  million,  or  15%,  primarily  driven 
by LCD glass price declines which were slightly higher  than 10% and 
a  decrease  of  $289  million  in  net  realized  gains  from  our  yen  and 
won-denominated currency hedge contracts;

• The  resolution  of  an  investigation  by  the  U.S.  Department  of  Justice 

and related costs in the total amount of $86 million;

• An increase of $71 million in acquisition and transaction related costs, 
driven primarily by expenses associated with the strategic realignment 
of our ownership interest in Dow Corning; and

Results of Operations

Selected highlights from our operations follow (in millions):

2017 Corporate Outlook
In 2017, Corning will continue to advance the objectives of its Strategy 
and  Capital  Allocation  Framework,  which  sets  its  leadership  priorities 
and  articulates  opportunities  across  its  businesses.  In  the  Display 
Technologies  segment,  we  expect  the  rate  of  growth  in  both  retail 
market and glass demand to be in the mid-single digit percentage, and 
an  overall  favorable  LCD  glass  price  environment,  with  price  declines 
more moderate than in 2016. In the Optical Communications segment, 
we  anticipate  sales  to  increase  by  a  low-teens  percentage  over  2016. 
In  the  Environmental  Technologies  segment,  we  expect  sales  to  be 
consistent  to  up  slightly  from  2016,  driven  by  continued  sales  growth 
in  the auto market, offset somewhat by lower heavy-duty volume. We 
expect growth in the Specialty Materials segment, the amount of which 
will  depend  on  the  timing  and  extent  of  customers  deploying  Gorilla 
Glass  5  and  other  Corning  innovations.  In  the  Life  Sciences  segment, 
we  expect  low-single  digit  sales  growth,  ahead  of  forecasted  market 
growth rates.

For the year ended December 31, 2016, net sales increased by $279 million, 
or 3%, when compared to the same period in 2015. The following items 
drove the increase:

also increased by $158 million driven by growth in fiber-to-the-home 
products in North America and the impact of two small acquisitions 
completed in the first quarter of 2015;

• An increase of $152 million in the Display Technologies segment, driven 
by the positive impact from the strengthening of the Japanese yen in 
the amount of $370 million and a mid-single digit percentage volume 
increase, offset somewhat by LCD glass price declines slightly higher 
than 10%;

• An  increase  of  $25  million  in  the  Optical  Communications  segment, 
driven primarily by an increase of $76 million in sales of carrier products 
and  the  impact  of  a  small  acquisition  completed  in  the  second 
quarter  of  2016,  partially  offset  by  production  issues  related  to  the 
implementation  of  new  manufacturing  software,  which  constrained 
our ability to manufacture product in the first half of 2016;

• A decrease of $21 million in the Environmental Technologies segment 
driven by a decline of $78 million in sales of diesel products due to the 
weakening  of  the  North  American  truck  market,  offset  partially  by 
an  increase  of  $57  million  in  sales  of  light-duty  substrates,  driven  by 
strength in the North American, European and Chinese markets;

• An  increase  of  $17  million  in  the  Specialty  Materials  segment,  driven 
by an increase in sales of Corning Gorilla Glass 5 and advanced optics 
products;

• An  increase  of  $18  million  in  the  Life  Sciences  segment,  driven  by 

volume growth in Europe, North America and China; and

• An increase of $88 million in the All Other segment, driven primarily by 

our glass tubing business acquired in the fourth quarter of 2015.

In  the  year  ended  December  31,  2016,  the  translation  impact  of 
fluctuations in foreign currency exchange rates, primarily the Japanese 
yen, positively affected Corning’s consolidated net sales in the amount 
of $330 million when compared to the same period in 2015.

For  the  year  ended  December  31,  2015,  net  sales  decreased  by 
$604  million,  or  6%,  when  compared  to  the  same  period  in  2014. The 
following items drove the decrease:

• A decrease of $765 million in the Display Technologies segment, driven 
by  the depreciation of  the Japanese yen versus  the U.S. dollar, which 
adversely impacted net sales in the amount of $446 million, and price 
declines  in  the  low-teens  on  a  percentage  basis.  Although  volume 
increased  in  the  mid-single  digits  in  percentage  terms,  growth  was 
muted  somewhat  by  weakness  in  demand  for  televisions,  computer 
monitors and mobile computing products;

• An increase of $328 million in the Optical Communications segment, 
driven by higher sales of enterprise network products, up $170 million, 
due  to  an  acquisition  completed  in  the  first  quarter  of  2015  and  an 
increase in data center products sales. Sales of carrier network products 

• A decrease in the Environmental Technologies segment of $39 million, 
driven by the translation impact from movements in foreign currency 
exchange rates versus the U.S. dollar, primarily the euro, of $57 million 
and lower sales of light duty diesel products in Europe, partially offset 
by  higher  volume  for  heavy-duty  diesel  and  light-duty  substrate 
products;

• A  decrease  of  $98  million  in  the  Specialty  Materials  segment,  driven 

primarily by a decline in advanced optics sales; and

• A  decrease  of  $41  million  in  the  Life  Sciences  segment  due  to  the 
impact  of  unfavorable  movements  in  foreign  exchange  rates  of 
$43 million.

In  the  year  ended  December  31,  2015,  the  translation  impact  of 
fluctuations in foreign currency exchange rates, primarily the Japanese 
yen and the euro, negatively affected Corning’s consolidated net sales in 
the amount of $663 million when compared to the same period in 2014.

In 2016, 2015 and 2014, sales in international markets accounted for 72%, 
70% and 77%, respectively, of total net sales.

Cost of Sales
The  types  of  expenses  included  in  the  cost  of  sales  line  item  are:  raw 
materials consumption, including direct and indirect materials; salaries, 
wages and benefits; depreciation and amortization; production utilities; 
production-related  purchasing;  warehousing  (including  receiving  and 
inspection);  repairs  and  maintenance;  inter-location  inventory  transfer 
costs; production and warehousing facility property insurance; rent for 
production facilities; and other production overhead.

Gross Margin
In  the  year  ended  December  31,  2016,  gross  margin  dollars  increased 
$93  million,  and  gross  margin  as  a  percentage  of  net  sales  remained 
consistent  at  40%  when  compared  to  the  same  period  last  year.  The 
increase  in  gross  margin  dollars  was  primarily  driven  by  the  positive 
impact  from  the  strengthening  of  the  Japanese  yen  in  the  amount 
of  $266  million,  an  increase  in  manufacturing  efficiency  and  cost 
reductions  in  our  Display  Technologies  and  Optical  Communications 
segments  which  added  approximately  $160  million,  a  more  favorable 
mix  of  products  sold  in  the  Optical  Communications  segment  and  an 
increase  in  volume  in  the  mid-single  digit  percentage  in  the  Display 
Technologies  segment.  Display  Technologies  segment  price  declines 
slightly above 10% partially offset the increase.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

In  the  year  ended  December  31,  2015,  gross  margin  dollars  and  gross 
margin as a percentage of net sales both declined when compared  to 
the  same  period  in  2014,  declining  $399  million  and  2%,  respectively. 
The  negative  impact  of  the  depreciation  of  the  Japanese  yen  versus 
the U.S. dollar in the amount of $368 million and price declines in the 
Display  Technologies  segment  in  the  low  teens  in  percentage  terms 
drove the decrease, but were partially offset by cost reductions and the 
impact  of  several  small  acquisitions  in  the  Optical  Communications 
in  the 
segment, 
Display  Technologies  and  Specialty  Materials  segments  and  lower 
acquisition-related  and  restructuring  costs.  Additionally,  our  Emerging 
Innovation  Group  and  Corning  Pharmaceutical  Technologies  business 
added $26 million in gross margin dollars in 2015, reflecting the growing 
significance of new business development.

in  manufacturing  performance 

improvements 

Selling, General and Administrative Expenses
In the year ended December 31, 2016, selling, general and administrative 
expenses decreased by $36 million when compared to the same period 
in 2015, driven primarily by the following items:

• A  decrease  of  $94  million  in  the  loss  on  the  mark-to-market  of  our 

defined benefit pension plans;

• The positive impact of the change in the contingent consideration fair 

value adjustment of $43 million; and

• The  absence  of  $25  million  of  post-combination  expenses 

incurred in 2015.

Partially offsetting these events were:

• An increase of $59 million in acquisition-related costs primarily related 
to  the  realignment  of  our  equity  interest  in  Dow  Corning  and  an 
acquisition completed in the second quarter of 2016;

• An increase of $49 million in litigation, regulatory and other legal costs, 
driven by the resolution of an investigation by the U.S. Department of 
Justice  and  an  environmental  matter  in  the  amount  of  $98  million, 
partially  offset  by  the  gain  of  $56  million  on  the  contribution  of  our 
equity interests in PCC and PCE as partial settlement of the asbestos 
litigation; and

• Higher  operating  expenses 

in 

the  Optical  Communications, 

Environmental Technologies and Specialty Materials segments.

When compared to the same period in 2015, as a percentage of net sales, 
selling, general and administrative expenses decreased by 1%.

In the year ended December 31, 2015, selling, general and administrative 
expenses increased by $312 million when compared to the same period 
in 2014, driven primarily by the following items:

• An  increase  of  $133  million  in  our  defined  benefit  pension  plans 

mark-to-market loss;

When  compared  to  the  same  period  in  2014,  as  a  percentage  of  net 
sales,  selling,  general  and  administrative  expenses  in  the  year  ended 
December 31, 2015 increased driven by lower net sales.

The types of expenses included in the selling, general and administrative 
expenses line item are: salaries, wages and benefits; travel; professional 
fees;  and  depreciation  and  amortization,  utilities,  and  rent  for 
administrative facilities.

Research, Development and Engineering 
Expenses
In  the  year  ended  December  31,  2016,  research,  development  and 
engineering expenses declined $27 million when compared to the same 
period in 2015 driven by the impact of a joint development agreement 
with  a  Display  Technologies  customer,  offset  partially  by  project 
development spending in the Optical Communications, Environmental 
Technologies  and  Specialty  Materials  segments.  As  a  percentage  of 
net  sales,  research,  development  and  engineering  expenses  remained 
consistent with the same period in 2015.

In  the  year  ended  December  31,  2015,  research,  development  and 
engineering  expenses  decreased  by  $46  million  when  compared  to 
the same period in 2014, driven by lower variable compensation and a 
decrease in the Display Technologies and Specialty Materials segments. 
As  a  percentage  of  net  sales,  research,  development  and  engineering 
expenses remained consistent with the same period in 2014.

Restructuring, Impairment, and Other Charges
Corning  recorded  restructuring,  impairment,  and  other  charges  and 
credits in 2016 and 2014, which affect  the comparability of our results 
for the periods presented. Additional information on restructuring and 
asset  impairment  is  found  in  Note  2  (Restructuring,  Impairment  and 
Other Charges) to the Consolidated Financial Statements. A description 
of those charges and credits follows:

2016 Activity

For the year ended December 31, 2016, we recorded charges of $77 million 
for employee related costs, asset disposals, and exit costs associated with 
restructuring  activities  with  total  cash  expenditures  of  approximately 
$12 million.

2015 Activity

For  the  year  ended  December  31,  2015,  we  did  not  record  significant 
restructuring, 
impairment  and  other  charges  or  reversals.  Cash 
expenditures for restructuring activities were $40 million.

• The absence of the positive impact of a contingent consideration fair 

value adjustment of $249 million recorded in 2014; and

2014 Activity

• An  increase  in  spending  in  the  Optical  Communications  segment 

driven by several acquisitions completed in 2015.

lower  spending 

Offsetting  these  increases  somewhat  were  a  decrease  in  variable 
compensation, 
in  the  Display  Technologies  and 
Specialty  Materials  segments  and  a  decline  in  acquisition-related 
and  post-combination  expenses,  which  were  higher  last  year  due  to 
additional  costs  incurred  related  to  the  acquisition  of  the  remaining 
equity interests of Samsung Corning Precision Materials.

For the year ended December 31, 2014, we recorded charges of $71 million 
for workforce reductions, asset disposals and write-offs, and exit costs for 
restructuring  activities  with  total  cash  expenditures  of  approximately 
$39 million.

(1)  Results include equity earnings for Dow Corning, which includes the silicones business and Hemlock Semiconductor business, through May 31, 2016, 

the date of the realignment of our ownership interest in Dow Corning.

(2) Results include equity earnings for Hemlock Semiconductor Group beginning on June 1, 2016.

On  May  31,  2016,  Corning  completed  the  strategic  realignment  of 
its  equity  investment  in  Dow  Corning  Corporation  (“Dow  Corning”) 
pursuant  to  the  Transaction  Agreement  announced  on  December  10, 
2015. Under the terms of the Transaction Agreement, Corning exchanged 
with  Dow  Corning  its  50%  stock  interest  in  Dow  Corning  for  100%  of 
the  stock  of  a  newly  formed  entity,  which  holds  an  equity  interest  in 
Hemlock Semiconductor Group and approximately $4.8 billion in cash.

The equity in earnings line on our income statement for the year ended 
December 31, 2016 reflects both the equity earnings from the silicones and 
polysilicones (Hemlock Semiconductor) businesses of Dow Corning from 
January 1, 2016 through May 31, 2016, the closing date of the Transaction 
Agreement,  and  seven  months  of  equity  earnings  from  Hemlock 
Semiconductor Group. Prior to the realignment of Dow Corning, equity 

earnings from the Hemlock Semiconductor business were reported on 
the equity in earnings line in Corning’s income statement, net of Dow 
Corning’s 35% U.S.  tax. Additionally, Corning reported its  tax on equity 
earnings  from  Dow  Corning  on  the  tax  provision  line  on  its  income 
statement at a U.S. tax provision rate of 7%. As part of the realignment, 
Hemlock  Semiconductor  Group  was  converted  to  a  partnership.  Each 
of  the  partners  is  responsible  for  the  taxes  on  their  portion  of  equity 
earnings. Therefore, post-realignment, Hemlock Semiconductor Group’s 
equity earnings is reported before tax on the equity in earnings line and 
Corning’s tax is reported on the tax provision line.

Refer to Note 7 (Investments) to the consolidated financial statements 
for additional information.

Translated earnings contracts
Included in the line item Translated earnings contract (loss) gain, net, is the impact of foreign currency hedges which hedge our translation exposure 
arising from movements in the Japanese yen, South Korean won, euro, New Taiwan dollar and Chinese yuan against the U.S. dollar and its impact on 
our net earnings. The following table provides detailed information on the impact of our translated earnings contract losses and gains:

Income Before Income Taxes
The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates  positively  affected  Corning’s  Income  before  income  taxes  in  the 
year  ended  December  31,  2016  in  the  amount  of  $304  million  when 

compared  to  2015. This  impact  was  partially  offset  by  the  decrease  in 
the realized gain from our foreign currency translation hedges related to 
translated earnings of $452 million.

Benefit (Provision) for Income Taxes
Our benefit (provision) for income taxes and the related effective income tax rates were as follows (dollars in millions):

Corning continues to indefinitely reinvest substantially all of its foreign 
earnings,  with  the  exception  of  an  immaterial  amount  of  current 
earnings  that  have  very  low  or  no  tax  cost  associated  with  their 
repatriation. Our current analysis indicates that we have sufficient U.S. 
liquidity,  including  borrowing  capacity,  to  fund  foreseeable  U.S.  cash 
needs  without  requiring  the  repatriation  of  foreign  cash.  One  time 
or  unusual  items  may  impact  our  ability  or  intent  to  keep  our  foreign 
earnings and cash indefinitely reinvested. As of December 31, 2016, taxes 
have not been provided on approximately $12.6 billion of accumulated 
foreign  unremitted  earnings  that  are  expected  to  remain  invested 
indefinitely. While it remains impracticable to calculate the tax cost of 
repatriating  our  total  unremitted  foreign  earnings,  such  cost  could  be 
material to the results of operations of Corning in a particular period.

We do not expect a material change to the amount of unrecognized tax 
benefits in the next 12 months.

Refer to Note 6 (Income Taxes) to the Consolidated Financial Statements 
for further details regarding income tax matters.

Benefit (provision) for income taxes

Effective tax rate 

The  effective  income  tax  rate  for  2016  differed  from  the  U.S.  statutory 
rate of 35% primarily due to the following items:

• Rate  differences  on  income  (loss)  of  consolidated  foreign  companies, 
including the benefit of excess foreign tax credits resulting from the 
inclusion of foreign earnings in U.S. income; and

• The tax-free nature of the realignment of our equity interest in Dow 
Corning during  the period, as well as  the release of  the deferred  tax 
liability  related  to  Corning’s  tax  on  Dow  Corning’s  undistributed 
earnings as of the date of the transaction.

The  effective  income  tax  rate  for  2015  differed  from  the  U.S.  statutory 
rate of 35% primarily due to the following items:

• Rate  differences  on  income  (loss)  of  consolidated  foreign  companies, 
including the benefit of excess foreign tax credits resulting from the 
inclusion of foreign earnings in U.S. income;

• The impact of equity in earnings of nonconsolidated affiliates reported 

in the financials, net of tax;

• $63  million  tax  expense  for  unrecognized  tax  benefit  primarily  for 
positions taken related to net transfer pricing adjustments (offset with 
benefit for competent authority relief); and

• $100  million  tax  benefit  primarily  related  to  change  in  judgment  on 
the realizability of deferred tax assets which is partially offset with tax 
expense from deferred tax allowance increases.

For the year ended December 31, 2016, comprehensive income increased 
by  $2,995  million  when  compared  to  the  same  period  in  2015,  driven 
by an increase of $2,356 million in net income attributable  to Corning 
Incorporated,  the  positive  impact  of  the  change  in  foreign  currency 
translation adjustments and an increase in unamortized actuarial gains 
for postretirement benefit plans.

For the year ended December 31, 2015, comprehensive income decreased 
by  $286  million  when  compared  to  the  same  period  in  2014,  driven 
by  a  decrease  of  $1,133  million  in  net  income  attributable  to  Corning 
Incorporated,  offset  by  the  positive  impact  of  the  change  in  foreign 
currency translation adjustments and the increase in unamortized gains 
for postretirement benefit plans.

The  decrease  in  the  loss  on  foreign  currency  translation  adjustments 
for  the  year  ended  December  31,  2016  in  the  amount  of  $486  million 
(after-tax) was driven by the following items: 1) the decrease in the loss 
on the translation of Corning’s consolidated subsidiaries in the amount 
of  $398  million,  largely  driven  by  the  strengthening  of  the  Japanese 
yen;  and  2)  the  decrease  in  the  loss  in  the  translation  of  Corning’s 
equity method investments in the amount of $88 million, driven by the 
realignment of our ownership interests in Dow Corning.

The increase in unamortized actuarial gains for postretirement benefit 
plans in the amount of $120 million (after-tax) is due to the following: 
1) the decrease of $65 million related to the reclassification of actuarial 
gains  to  the  income  statement,  largely  due  to  higher  pension  asset 
returns; 2) an increase in actuarial losses of $3 million; and 3) a decrease 
of $188 million in unamortized losses related to our equity companies. 
The  significant  change  was  driven  by  the  release  of  Dow  Corning’s 
unamortized  actuarial  loss,  which  was  included  in  the  gain  on  the 
realignment of our ownership interests in Dow Corning.

The  decrease  in  the  loss  on  foreign  currency  translation  adjustments 
for  the  year  ended  December  31,  2015  in  the  amount  of  $483  million 
(after-tax) was driven by the following items: 1) the decrease in the loss 
in the translation of Corning’s consolidated subsidiaries in the amount 
of $334 million; 2) the decrease in the loss in the translation of Corning’s 
equity  method  investments  in  the  amount  of  $13  million;  and  3)  the 
absence  of  the  reclassification  of  a  gain  to  net  income  in  2014  in  the 
amount of $136 million related to the acquisition of Samsung Corning 
Precision Materials.

The increase in unamortized gains for postretirement benefit plans in 
the  amount  of  $402  million  (after-tax)  is  due  to  the  following:  1)  the 
increase in  the reclassification  to  the income statement of $81 million 
of actuarial losses in our defined benefit pension plans, largely driven by 
lower investment returns; 2) a decrease in actuarial losses of $119 million; 
and  3)  the  increase  in  actuarial  gains  of  $202  million  from  our  equity 
affiliate Dow Corning.

Equity) to the Consolidated Financial Statements for additional details.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Core Performance Measures

In managing the Company and assessing our financial performance, we 
supplement  certain  measures  provided  by  our  consolidated  financial 
statements with measures adjusted to exclude certain items, to arrive 
at core performance measures. We believe reporting core performance 
measures  provides  investors  greater  transparency  to  the  information 
used  by  our  management  team  to  make  financial  and  operational 
decisions. Corning has adopted the use of constant currency reporting 
for  the  Japanese  yen  and  South  Korean  won,  and  uses  an  internally 
derived  yen-to-dollar  management  rate  of  ¥99  and  won-to-dollar 
management rate of ₩1,100.

Net sales, equity in earnings of affiliated companies and net income are 
adjusted to exclude the impacts of changes in the Japanese yen and the 
South Korean won, gains and losses on our translated earnings contracts, 
acquisition-related  costs,  certain  discrete  tax  items,  restructuring 
and  restructuring-related  charges,  certain  litigation-related  expenses, 
pension  mark-to-market  adjustments  and  other  items  which  do 
not  reflect  on-going  operating  results  of  the  Company  or  our  equity 
affiliates.  Management’s  discussion  and  analysis  on  our  reportable 
segments has also been adjusted for these items, as appropriate. These 

measures  are  not  prepared  in  accordance  with  Generally  Accepted 
Accounting Principles in the United States (“GAAP”). We believe investors 
should  consider  these  non-GAAP  measures  in  evaluating  our  results 
as  they  are  more  indicative  of  our  core  operating  performance  and 
how management evaluates our operational results and  trends. These 
measures  are  not,  and  should  not  be  viewed  as  a  substitute  for  GAAP 
reporting measures. With respect to the Company’s outlooks for future 
periods,  it  is  not  able  to  provide  reconciliations  for  these  non-GAAP 
measures  because  the  Company  does  not  forecast  the  movement 
of  the  Japanese  yen  and  South  Korean  won  against  the  U.S.  dollar,  or 
other items that do not reflect ongoing operations, nor does it forecast 
items  that  have  not  yet  occurred  or  are  out  of  the  Company’s  control. 
As a result, the Company is unable to provide outlook information on a 
GAAP basis.

See  “Use  of  Non-GAAP  Financial  Measures”  for  details  on  core 
performance  measures.  For  a  reconciliation  of  non-GAAP  performance 
measures  to  their  most  directly  comparable  GAAP  financial  measure, 
please see “Reconciliation of Non-GAAP Measures” below.

In all segments except Display Technologies, core net sales are consistent 
with  GAAP  net  sales.  Because  a  significant  portion  of  revenues  in  the 
Display  Technologies  segment  are  denominated  in  Japanese  yen,  this 
segment’s  net  sales  are  adjusted  to  remove  the  impact  of  translating 
yen  into  dollars.  As  of  January  1,  2015,  we  use  an  internally  derived 
management  rate  of  ¥99,  which  is  closely  aligned  to  our  current 
yen-denominated hedges related to translated earnings, and have recast 
all periods presented based on this rate in order to effectively remove the 
impact of changes in the Japanese yen.

Core net sales decreased by $90 million in the year ended December 31, 
2016 when compared to the same period in 2015. Core net sales in the 
Display Technologies segment decreased by $218 million, or 6%, in  the 
year ended December 31, 2016, driven by LCD glass price declines slightly 
higher than 10%, partially offset by an increase in volume of a mid-single 
digit percentage.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Core  net  sales  decreased  by  $155  million  to  $9.8  billion  in  the  year 
ended  December  31,  2015  when  compared  to  the  same  period  in 
2014.  The  decline  was  driven  by  a  decrease  of  $318  million  in  the 
Display  Technologies  segment  primarily  due  to  price  declines  in  the 
low-teens  on  a  percentage  basis.  Although  volume  increased  in  the 
mid-single  digits  in  percentage  terms,  growth  was  muted  somewhat 
by weakness in demand for televisions, computer monitors and mobile 
computing products.

The translation impact from movements in foreign currency exchange 
rates  in  the  years  ended  December  31,  2016  and  2015,  excluding  the 
Japanese  yen  and  South  Korean  won,  negatively  affected  core  net 
sales in the amount of $39 million and $215 million, respectively, when 
compared to the prior years.

Core Earnings

2016 vs. 2015

In  the  year  ended  December  31,  2016,  we  generated  core  earnings  of 
$1,774 million, or $1.55 per share, compared to $1,882 million, or $1.40 per 
share,  in  the  year  ended  December  31,  2015.  The  decrease  was  due  to 
declines  in  the  Display  Technologies  and  Environmental  Technologies 
segments. Slightly offsetting the decline was higher core earnings in the 
Optical Communications segment, up $16 million, driven by higher sales 
volume  in  carrier  network  products,  the  favorable  translation  impact 
from  movements  in  foreign  currency  exchange  rates,  excluding  the 
Japanese yen and South Korean won, of $13 million and manufacturing 
efficiencies gained through cost reductions.

2015 vs. 2014

In  the  year  ended  December  31,  2015,  we  generated  core  earnings  of 
$1,882  million,  or  $1.40  per  share,  compared  to  $2,023  million,  or  $1.42 
per  share  in  the  year  ended  December  31,  2014. The  decrease  was  due 
to  lower  core  earnings  in  the  Display  Technologies,  Environmental 
Technologies,  Specialty  Materials  and  Life  Sciences  segments,  and  the 

unfavorable  translation  impact  from  movements  in  foreign  currency 
exchange  rates,  excluding  the  Japanese  yen  and  South  Korean  won, 
of $57 million. Slightly offsetting  the decline is higher core earnings in 
the Optical Communications segment, up $61 million, driven by higher 
sales volume for both carrier network and enterprise network products, 
the  favorable  impact  of  several  acquisitions  completed  this  year  and 
manufacturing efficiencies gained through cost reductions.

Included  in  core  earnings  for  the  years  ended  December  31,  2016,  2015 
and 2014 is net periodic pension expense in the amount of $50 million, 
$62  million  and  $74  million,  respectively,  which  excludes  the  annual 
pension mark-to-market adjustments. In the years ended December 31, 
2016, 2015 and 2014, the mark-to-market adjustments were a pre-tax loss 
of $67 million, $165 million and $29 million, respectively. Refer to Note 13

Reconciliation of Non-GAAP Measures
We  utilize  certain  financial  measures  and  key  performance  indicators 
that are not calculated in accordance with GAAP to assess our financial 
and  operating  performance.  A  non-GAAP  financial  measure  is  defined 
as  a  numerical  measure  of  a  company’s  financial  performance  that  (i) 
excludes  amounts,  or  is  subject  to  adjustments  that  have  the  effect 
of  excluding  amounts,  that  are  included  in  the  comparable  measure 
calculated and presented in accordance with GAAP in the statement of 
income or statement of cash flows, or (ii) includes amounts, or is subject 
to  adjustments  that  have  the  effect  of  including  amounts,  that  are 

excluded from the comparable measure as calculated and presented in 
accordance with GAAP in the statement of income or statement of cash 
flows.

Core net sales, core equity in earnings of affiliated companies and core 
earnings are non-GAAP financial measures utilized by our management 
to analyze financial performance without the impact of items that are 
driven  by  general  economic  conditions  and  events  that  do  not  reflect 
the underlying fundamentals and trends in the Company’s operations.

The  following  tables  reconcile  our  non-GAAP  financial  measures  to  their  most  directly  comparable  GAAP  financial  measure  (amounts  in  millions 
except percentages and per share amounts):

In the first quarter of 2015, we changed the yen-to-dollar management rate from ¥93 to ¥99 to closely align with the yen-denominated hedges 
entered into for the years 2015 through 2017. Prior periods presented have been recast based on the new rate.

See “Items Excluded from GAAP Measures” below for the descriptions of the footnoted reconciling items.

24

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Items Excluded from GAAP Measures

Items which we exclude from GAAP measures to arrive at Core performance measures are as follows:

(1)  Constant-currency adjustments:

Constant-yen: Because a significant portion of Display Technologies segment revenues and manufacturing costs are denominated in Japanese 
yen,  management  believes  it  is  important  to  understand  the  impact  on  core  earnings  of  translating  yen  into  dollars.  Presenting  results  on  a 
constant-yen basis mitigates the translation impact of the Japanese yen, and allows management to evaluate performance period over period, 
analyze underlying trends in our businesses, and establish operational goals and forecasts. As of January 1, 2015, we used an internally derived 
management rate of ¥99, which is closely aligned to our current yen portfolio of foreign currency hedges, and have recast all periods presented 
based on this rate in order to effectively remove the impact of changes in the Japanese yen.

Constant-won: Because a significant portion of Corning Precision Materials’ costs are denominated in South Korean won, management believes it 
is important to understand the impact on core earnings from translating won into dollars. Presenting results on a constant-won basis mitigates 
the translation impact of the South Korean won, and allows management to evaluate performance period over period, analyze underlying trends 
in our businesses, and establish operational goals and forecasts without the variability caused by the fluctuations caused by changes in the rate 
of this currency. We use an internally derived management rate of ₩1,100, which is consistent with historical prior period averages of the won.

(2)  Translated  earnings  contract  loss  (gain): We  have  excluded  the  impact  of  the  gains  and  losses  of  our  translated  earnings  contracts  for  each 

period presented. 

(3)  Acquisition-related  costs:  These  expenses  include  intangible  amortization,  inventory  valuation  adjustments  and  external  acquisition-related 

deal costs.

(4)  Discrete tax items and other tax-related adjustments: This represents the removal of discrete adjustments attributable to changes in tax law and 
changes in judgment about the realizability of certain deferred tax assets, as well as other non-operational tax-related adjustments, including the 
tax effect of transfer pricing out-of-period adjustments in 2014 and 2015. 

(5)  Litigation,  regulatory  and  other  legal  matters:  Includes  amounts  related  to  the  Pittsburgh  Corning  Corporation  (PCC)  asbestos  litigation, 

adjustments to our estimated liability for environmental-related items and other legal matters.

(6)  Restructuring, impairment and other charges: This amount includes restructuring, impairment and other charges, including goodwill impairment 

charges and other expenses and disposal costs not classified as restructuring expense.

(7)  Liquidation of subsidiary: The partial impact of non-restructuring related items due to the decision to liquidate a consolidated subsidiary that is 

not significant.

(8)  Equity in earnings of affiliated companies: These adjustments relate to items which do not reflect expected on-going operating results of our 

affiliated companies, such as restructuring, impairment and other charges and settlements under “take-or-pay” contracts. 

(9) 

Impacts from the acquisition of Samsung Corning Precision Materials: Pre-acquisition gains and losses on previously held equity investment and 
other gains and losses related to the acquisition, including post-combination expenses, fair value adjustments to the indemnity asset related to 
contingent consideration and the impact of the withholding tax on a dividend from Samsung Corning Precision Materials.

(10)  Post-combination expenses: Post-combination expenses incurred as a result of an acquisition in the first quarter of 2015.

(11)  Pension  mark-to-market  adjustment:  Mark-to-market  pension  gains  and  losses,  which  arise  from  changes  in  actuarial  assumptions  and  the 

difference between actual and expected returns on plan assets and discount rates.

(12)  Gain  on  realignment  of  equity  investment:  Gain  recorded  upon  the  completion  of  the  strategic  realignment  of  our  ownership  interest  in 

Dow Corning.

(13)  Taiwan power outage: Impact of the power outage that temporarily halted production at our Tainan, Taiwan manufacturing location in the second 
quarter  of  2016. The  impact  includes  asset  write-offs  and  charges  for  facility  repairs,  offset  somewhat  by  partial  reimbursement  through  our 
insurance program.

Reportable Segments

Our reportable segments are as follows:

• Display Technologies – manufactures glass substrates primarily for flat 

panel liquid crystal displays.

• Optical  Communications  –  manufactures  carrier  and  enterprise 

network components for the telecommunications industry.

• Environmental Technologies  –  manufactures  ceramic  substrates  and 

filters for automotive and diesel emission control applications.

• Specialty Materials – manufactures products that provide more than 
150 material formulations for glass, glass ceramics and fluoride crystals 
to meet demand for unique customer needs.

• Life  Sciences  –  manufactures  glass  and  plastic  labware,  equipment, 
media  and  reagents  enabling  workflow  solutions  for  scientific 
applications.

All  other  segments  that  do  not  meet  the  quantitative  threshold 
for  separate  reporting  have  been  grouped  as  “All  Other.”  This  group 
is  primarily  comprised  of  the  results  of  Corning’s  Pharmaceutical 
Technologies  business,  our  non-LCD  glass  business,  new  product  lines 
and development projects, as well as certain corporate investments such 
as Eurokera and Keraglass equity affiliates.

CORNING INCORPORATED - 2016 Annual Report 
 
Management’s Discussion and Analysis of Financial Condition and Results of Operations

We prepared the financial results for our reportable segments on a basis 
that is consistent with the manner in which we internally disaggregate 
financial  information  to  assist  in  making  internal  operating  decisions. 
We included the earnings of equity affiliates that are closely associated 
with our reportable segments in the respective segment’s net income. 
We  have  allocated  certain  common  expenses  among  our  reportable 
segments  differently  than  we  would  for  stand-alone  financial 
information  prepared 
in  accordance  with  GAAP.  Our  reportable 
segments  include  non-GAAP  measures  which  are  not  prepared  in 
accordance with GAAP. We believe investors should consider these non-

GAAP measures in evaluating our results as they are more indicative of 
our  core  operating  performance  and  how  management  evaluates  our 
operational  results  and  trends.  These  measures  are  not,  and  should 
not  be  viewed  as  a  substitute  for  GAAP  reporting  measures.  For  a 
reconciliation of non-GAAP performance measures to their most directly 
comparable GAAP financial measure, please see “Reconciliation of Non-
GAAP  Measures”  above.  Segment  net  income  may  not  be  consistent 
with measures used by other companies. The accounting policies of our 
reportable segments are the same as those applied in the consolidated 
financial statements.

As Reported

2016 vs. 2015
Net sales in the Display Technologies segment increased by $152 million, 
or 5%, in the year ended December 31, 2016 when compared to the same 
period in 2015, driven by the positive impact from the strengthening of 
the Japanese yen in the amount of $370 million and a mid-single digit 
percentage volume increase driven by growth in television screen size. 
This  increase  was  partially  offset  by  LCD  glass  price  declines  slightly 
higher than 10%.

Net  income  in  the  Display  Technologies  segment  decreased  by 
$160  million,  or  15%,  in  the  year  ended  December  31,  2016  when 
compared to the same period in 2015. This decrease was driven by the 
following items:

• The impact of price declines slightly higher than 10%;

• A  decrease  of  $289  million  in  the  realized  gain  from  our  yen  and 

won-denominated currency hedges; and

• An increase of $44 million in asset write-off expenses.

The decrease in net income was partially offset by the following items:

• A mid-single digit percentage increase in volume;

• An increase of $35 million in the gain on the fair value adjustment of 
the contingent consideration resulting from the acquisition of Corning 
Precision Materials;

• Improvements in manufacturing efficiency; and

• A decline in operating expenses.

The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates  positively  impacted  Display Technologies  net  income  in  the  year 
ended December 31, 2016 in the amount of $213 million when compared 
to  the  same  period  in  2015. This  impact  was  more  than  offset  by  the 
decrease in the realized gain from our translated earnings contracts in 
the amount of $289 million.

26

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

2015 vs. 2014
When compared to the same period in 2014, the decrease in net sales of 
$765 million, or 20%, in the year ended December 31, 2015 was driven by 
price declines in the low-teens in percentage terms and the depreciation 
of  the  Japanese  yen  versus  the  U.S.  dollar,  which  adversely  impacted 
net  sales  in  the  amount  of  $446  million.  Sequentially,  fourth  quarter 
LCD  glass  price  declines  were  the  lowest  sequential  decline  of  2015. 
Although volume increased in the mid-single digits in percentage terms, 
growth was muted somewhat by weakness in demand for  televisions, 
computer monitors and mobile computing products. Additionally, in the 
third quarter of 2015, we experienced temporary share loss at one of our 
largest  customers  due  to  a  contract  dispute. We  resolved  the  dispute 
in  the  fourth  quarter  of  2015,  and  extended  our  long-term  supply 
agreement with this customer to 2025.

Net  income  in  the  Display  Technologies  segment  decreased  by 
$301  million,  or  22%,  in  the  year  ended  December  31,  2015  when 
compared to the same period in 2014. This decrease was driven by the 
following items:

• The impact of price declines in the low-teens in percentage terms that 

more than offset the mid-single digit percent increase in volume;

• A decrease of $184 million in the gain on the fair value adjustment of 
the contingent consideration resulting from the acquisition of Corning 
Precision Materials; and

• The  absence  of  a  gain  on  the  settlement  of  an  intellectual  property 

dispute recorded in 2014 in the amount of $38 million.

by  a  mid-single  digit  percentage  volume  increase.  Core  earnings  also 
decreased in  this period, down $69 million, or 6%, driven by LCD glass 
price declines slightly higher  than 10%, partially offset by a mid-single 
digit  percentage  volume  increase,  improvements  in  manufacturing 
efficiency and a decline in operating expenses.

2015 vs. 2014
When  compared  to  the  same  period  in  2014,  core  net  sales  in  the 
Display Technologies segment decreased by $318 million, or 8%, in  the 
year ended December 31, 2015, driven primarily by price declines in the 
low-teens in percentage terms. Sequentially, LCD glass price declines in 
the  fourth  quarter  remained  moderate.  Although  volume  increased  in 
the mid-single digits in percentage terms, growth was muted somewhat 
by weakness in demand for televisions, computer monitors and mobile 
computing  products.  Additionally,  in  the  third  quarter  of  2015,  we 
experienced temporary share loss at one of our largest customers due 
to a contract dispute. We resolved the dispute in the fourth quarter of 
2015, and extended our long-term supply agreement with this customer 
to 2025.

Core  earnings  in  the  Display Technologies  segment  in  the  year  ended 
December 31, 2015 declined by $168 million, or 14%, when compared to 
the same period last year. Volume increases in the mid-single digits in 
percentage terms, lower manufacturing costs and a decline in operating 
expenses were more than offset by price declines in the low-teens and 
the  absence  of  a  gain  on  the  settlement  of  an  intellectual  property 
dispute recorded in 2014 in the amount of $38 million.

The decrease in net income was partially offset by the following items:

Other Information

• Improvements in manufacturing efficiency of $79 million;

• A decline in transaction and acquisition-related costs in the amounts 

of $73 million and $37 million, respectively;

• A  decrease  of  $40  million  in  restructuring,  impairment  and  other 

charges; and

• A decline in operating expenses.

The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates negatively impacted Display Technologies net income in the year 
ended December 31, 2015 in the amount of $233 million when compared 
to  the  same  period  in  2014.  This  impact  was  partially  offset  by  the 
increase in  the realized gain from our  translated earnings contracts in 
the amount of $126 million.

Core Performance

2016 vs. 2015
Core  net  sales  decreased  by  $218  million,  or  6%,  in  the  year  ended 
December 31, 2016 when compared  to  the same period in 2015, driven 
by  LCD  glass  price  declines  slightly  higher  than  10%,  partially  offset 

The  Display Technologies  segment  has  a  concentrated  customer  base 
comprised of LCD panel and color filter makers primarily located in Japan, 
South Korea, China and Taiwan. In 2016, 2015 and 2014, three customers 
of the Display Technologies segment, which individually accounted for 
more  than  10%  of  segment  net  sales,  accounted  for  a  combined  65%, 
62% and 61% of total segment sales in those years. Our near-term sales 
and profitability would be impacted if any of these significant customers 
were unable to continue to purchase our products.

Corning has invested to expand capacity to meet the projected demand 
for LCD glass substrates. In 2016, 2015 and 2014, capital spending in this 
segment was $464 million, $594 million and $492 million, respectively.

Outlook:

For  full-year  2017,  Corning  expects  the  rate  of  growth  in  both  retail 
market  and  glass  demand  to  be  in  the  mid-single  digit  percentages. 
In  the  first  quarter  of  2017,  the  company  expects  Corning’s  volume  to 
increase by mid-teen percentage year over year, and decline by mid-single 
digit percentage sequentially. The company expects an overall favorable 
LCD glass price environment for the full year, with price declines more 
moderate than in 2016.

As Reported

2016 vs. 2015
In  the  year  ended  December  31,  2016,  net  sales  of  the  Optical 
Communications segment increased $25 million, or 1%, when compared 
to the same period in 2015, driven by an increase in carrier network sales. 
The  sales  increase  was  driven  by  fiber-to-the-home  products  in  North 
America, higher sales of optical fiber and the impact of an acquisition 
completed in the second quarter of 2016. These increases were partially 
offset  by  production  issues  related  to  the  implementation  of  new 
manufacturing software, which constrained our ability to manufacture 
product in the first half of 2016. Production returned to normal levels at 
the end of the second quarter. The translation impact from movements 
in foreign currency exchange rates in 2016 negatively impacted Optical 
Communications net sales in the amount of $8 million, when compared 
to the same period in 2015.

income 

in  the  Optical  Communications  segment 

increased 
Net 
$8 million, or 3%, in the year ended December 31, 2016 when compared 
to the same period in 2015. The increase was driven by cost reductions 
and the continuation of the favorable shift toward sales of our solutions 
products,  partially  offset  by  the  impact  of  the  production  issues 
described above, costs incurred related to a small acquisition completed 
in  the  second  quarter  of  2016  and  restructuring  and  asset  write-off 
expenses. Movements in foreign exchange rates positively impacted net 
income in the amount of $12 million when compared to 2015.

2015 vs. 2014
In  the  year  ended  December  31,  2015,  net  sales  of  the  Optical 
Communications  segment  increased  by  $328  million,  or  12%,  when 
compared  to  the  same  period  in  2014,  driven  by  an  increase  in  both 
carrier  network  and  enterprise  network  products.  Carrier  networks 
increased by $158 million, driven by higher sales of fiber-to-the-home and 
cable products in North America and the impact of recent acquisitions, 
offset somewhat by lower sales of wireless products and fiber and cable 
products in Europe. Sales declined in Europe driven by lower volume and 
the  negative  impact  of  movements  in  the  euro  exchange  rate  versus 
the U.S. dollar. Enterprise network sales grew by $170 million, primarily 
due to the impact of an acquisition completed in 2015 and an increase 
in  data  center  product  sales. The  translation  impact  from  movements 
in foreign currency exchange rates in 2015 negatively impacted Optical 
Communications net sales in the amount of $101 million when compared 
to the same period in 2014.

28

The increase in net income of $43 million, or 22%, was primarily driven 
by higher sales volume for both carrier network and enterprise network 
products and manufacturing efficiencies gained through cost reductions, 
offset somewhat by acquisition-related and post-combination expenses 
associated with three acquisitions completed in the first quarter of 2015. 
Also somewhat offsetting the increase were price declines and a small 
legal  settlement.  The  translation  impact  from  movements  in  foreign 
currency exchange rates did not significantly impact net income of this 
segment  in  the  year  ended  December  31,  2015  when  compared  to  the 
same period in 2014.

Core Performance

2016 vs. 2015
Core earnings increased $16 million, or 6%, in the year ended December 
31,  2016,  driven  by  higher  sales  of  our  solutions  products  and  cost 
reductions,  partially  offset  by  the  impact  of  the  production  issues 
described  above.  Movements  in  foreign  exchange  rates  positively 
impacted core earnings in the amounts of $12 million when compared 
to 2015.

2015 vs. 2014
In  the  year  ended  December  31,  2015,  core  earnings  increased  by 
$61 million, or 28%, driven by higher sales volume for both carrier network 
and enterprise network products and manufacturing efficiencies gained 
through cost reductions, offset somewhat by price declines.

The  Optical  Communications  segment  has  a  concentrated  customer 
base.  In  the  year  ended  December  31,  2016,  one  customer,  which 
individually  accounted  for  more  than  10%  of  segment  net  sales, 
accounted for 15% of total segment net sales. In the year ended December 
31, 2015, two customers, which individually accounted for more than 10% 
of segment net sales, accounted for 22% of total segment net sales. In 
the  year  ended  December  31,  2014,  one  customer,  which  individually 
accounted for more than 10% of segment net sales, accounted for 11% of 
total segment net sales.

Outlook:

In the first quarter of 2017, year-over-year Optical Communications sales 
growth is expected to be at least 25%. Full-year 2017 sales are expected 
to increase by a low-teens percentage over 2016.

Core Performance

2016 vs. 2015
Net  sales  in  the  Environmental  Technologies  segment  decreased  by 
$21 million, or 2%, in the year ended December 31, 2016 when compared 
to the same period in 2015, driven by a decrease of $78 million in sales 
of diesel products due to the weakening of the heavy-duty diesel truck 
market in North America, offset partially by an increase of $57 million in 
light-duty  substrates  sales,  driven  by  strength  in  the  North  American, 
European  and  Chinese  markets.  Net  income  decreased  by  $28  million, 
or  17%,  driven  by  lower  sales  of  heavy-duty  diesel  products  and  our 
investment  in  capacity  for  our  gas  particulate  filters.  Movements  in 
foreign  exchange  rates  versus  the  U.S.  dollar  negatively  impacted  net 
sales  and  net  income  in  this  segment  in  the  amounts  of  $22  million 
and $8 million, respectively, in the year ended December 31, 2016, when 
compared to the same period in 2015.

2015 vs. 2014
In the year ended December 31, 2015, net sales of this segment decreased 
by $39 million, or 4%, when compared to the same period in 2014. Sales of 
automotive light-duty substrates declined driven almost entirely by the 
negative impact of movements in the euro exchange rate versus the U.S. 
dollar,  partially  offset  by  higher  volume  in  North  America  and  Europe. 
Sales of diesel products also declined in these periods, driven by lower 
sales  of  light-duty  diesel  products  in  Europe  and  the  negative  impact 
of the movements in the euro exchange rate, partially offset by higher 
volume for heavy-duty diesel. The translation impact from movements 
in  foreign  currency  exchange  rates  versus  the  U.S.  dollar,  primarily  the 
euro, negatively impacted net sales in the Environmental Technologies 
segment  in  2015  in  the  amount  of  $57  million  when  compared  to  the 
same period in 2014.

Net income declined in the year ended December 31, 2015 by $17 million, 
or 10%, when compared to the same period in 2014, driven predominantly 
by lower sales,  the unfavorable impact of  the depreciation of  the euro 
versus  the  U.S.  dollar  and  facility  expansion  costs  to  support  growth 
in  China. The  translation  impact  from  movements  in  foreign  currency 
exchange  rates  versus  the  U.S.  dollar,  primarily  the  euro,  negatively 
impacted  net  income  in  the  Environmental  Technologies  segment  in 
the  amount  of  $21  million  in  the  year  ended  December  31,  2015  when 
compared to the same period in 2014.

2016 vs. 2015
Core  earnings  decreased  by  $25  million,  or  16%,  in  the  year  ended 
December  31,  2016,  driven  by  the  items  impacting  our  “As  Reported” 
results described above.

2015 vs. 2014
Core earnings declined by $22 million, or 12%, in the year ended December 
31, 2015, when compared to the same period in 2014, driven predominantly 
by lower sales,  the unfavorable impact of  the depreciation of  the euro 
versus  the  U.S.  dollar  and  facility  expansion  costs  to  support  growth 
in  China. The  translation  impact  from  movements  in  foreign  currency 
exchange  rates  versus  the  U.S.  dollar,  primarily  the  euro,  negatively 
impacted  net  income  in  the  Environmental  Technologies  segment  in 
the  amount  of  $21  million  in  the  year  ended  December  31,  2015  when 
compared to the same period in 2014.

The  Environmental  Technologies  segment  sells  to  a  concentrated 
customer base of catalyzer and emission control systems manufacturers, 
who then sell to automotive and diesel engine manufacturers. Although 
our  sales  are  to  the  emission  control  systems  manufacturers,  the  use 
of our substrates and filters is generally required by  the specifications 
of  the  automotive  and  diesel  vehicle  or  engine  manufacturers.  For 
2016,  2015  and  2014,  net  sales  to  three  customers,  which  individually 
accounted for more than 10% of segment sales, accounted for 85%, 86% 
and  88%,  respectively,  of  total  segment  sales. While  we  are  not  aware 
of any significant customer credit issues with our direct customers, our 
near-term  sales  and  profitability  would  be  impacted  if  any  individual 
customers were unable to continue to purchase our products.

Outlook:

For the first quarter of 2017, year-over-year segment sales are expected 
to be consistent to down slightly. Full-year 2017 sales are expected to be 
consistent to up slightly from last year with continued strength in the 
automotive market and lower demand for heavy-duty diesel products. 
Sales of the company’s new gas particulate filters are expected to begin 
during the second half of 2017.

As Reported

2016 vs. 2015
Net sales in the Specialty Materials segment increased by $17 million, or 
2%, in the year ended December 31, 2016 when compared to the same 
period in 2015, driven by an increase in sales of Corning Gorilla Glass 5 
and  advanced  optics  products.  Although  Corning  Gorilla  Glass  sales 
were lower in the first three quarters of 2016, sales in the fourth quarter 
of 2016 increased approximately 22% over the same period last year, led 
by the rapid adoption of Corning Gorilla Glass 5. Net income increased 
by  $7  million,  or  4%,  driven  by  manufacturing  cost  reductions,  higher 
advanced optics sales and  the impact of Gorilla Glass 5, offset slightly 
by  higher  research  and  development  costs.  Movements  in  foreign 
exchange rates did not materially impact net sales and net income in 
the Specialty Materials segment in the twelve months ended December 
31, 2016 when compared to the same period in 2015.

2015 vs. 2014
Net sales for the year ended December 31, 2015 decreased by $98 million, 
or 8%, when compared to the same period in 2014, primarily due to lower 
sales of advanced optics products. This decline was driven by weakness 
in the semiconductor industry, delays in a large aerospace and defense 
program  and  the  depreciation  of  the  euro  versus  the  U.S.  dollar.  The 
translation impact from movements in foreign currency exchange rates 
negatively  impacted  net  sales  in  the  Specialty  Materials  segment  in 
the amount of $12 million in 2015 when compared to the same period 
in 2014.

When compared to the same period in 2014, the increase in net income 
of $29 million, or 21%, in the year ended December 31, 2015 was driven 
by  an  increase  in  Corning  Gorilla  Glass  volume,  improvements  in 
manufacturing efficiency and lower operating expenses gained through 
cost  reductions,  offset  somewhat  by  a  decrease  in  sales  of  advanced 

optics  products.  The  translation  impact  from  movements  in  foreign 
currency exchange rates did not significantly impact net income of this 
segment in 2015 when compared to the same period in 2014.

Core Performance

2016 vs. 2015
Core earnings in the twelve months ended December 31, 2016 increased 
by $11 million, or 6%, driven primarily by cost reductions and an increase 
in  advanced  optics  and  Gorilla  Glass  5  sales,  offset  slightly  by  higher 
research and development costs.

2015 vs. 2014
When compared  to  the same period last year, core earnings increased 
by  $18  million,  or  11%,  in  the  year  ended  December  31,  2015,  driven 
by  an  increase  in  Corning  Gorilla  Glass  volume,  improvements  in 
manufacturing efficiency and lower operating expenses gained through 
cost  reductions,  offset  somewhat  by  a  decrease  in  sales  of  advanced 
optics products.

For  2016,  2015  and  2014,  three  customers  of  the  Specialty  Materials 
segment,  which 
individually  accounted  for  more  than  10%  of 
segment  sales,  accounted  for  56%,  56%  and  51%,  respectively,  of  total 
segment sales.

Outlook:

In  the  first  quarter  of  2017,  year-over-year  segment  sales  growth  is 
expected to be in the high-teen percentages. The company expects full-
year 2017 segment sales to increase, with the rate of growth dependent 
on  the  timing  and  extent  of  customers  deploying  Gorilla  Glass  5  and 
other Corning innovations.

Core Performance

2016 vs. 2015
Net sales in the Life Sciences segment increased by $18 million, or 2%, in 
the year ended December 31, 2016 when compared to the same period 
in 2015, driven by volume growth in North America, China and Europe, 
slightly  offset  by  the  impact  of  movements  in  foreign  exchange  rates 
in the amount of $11 million. Net income declined by $3 million, or 5%, 
driven by asset write-offs and exit costs and the impact of movements 
in foreign exchange rates of $7 million, offset slightly by higher volume.

2015 vs. 2014
Net sales for the year ended December 31, 2015 decreased by $41 million, 
or 5%, when compared to the same period in 2014, due to the negative 
impact of the strengthening of the U.S. dollar versus foreign currencies, 
which negatively impacted net sales by $43 million. Net income in the 
Life Sciences segment declined by $6 million, or 9%, when compared to 
the same period in 2014, with the negative impact from movements in 
foreign exchange rates in the amount of $14 million more than offsetting 
improvements in manufacturing efficiency.

2016 vs. 2015
In the year ended December 31, 2016, core earnings in the Life Sciences 
segment  increased  by  $4  million,  or  5%,  when  compared  to  the  same 
period last year, with higher volume more than offsetting the negative 
impact from movements in foreign exchange rates.

2015 vs. 2014
In the year ended December 31, 2015, core earnings in the Life Sciences 
segment  declined  by  $10  million,  or  12%,  when  compared  to  the  same 
period  in  2014,  with  the  negative  impact  from  movements  in  foreign 
exchange  rates  more  than  offsetting  improvements  in  manufacturing 
efficiency.

For  2016,  2015  and  2014,  two  customers  in  the  Life  Sciences  segment, 
which individually accounted for more  than 10% of  total segment net 
sales, collectively accounted for 46%, 46% and 45%, respectively, of total 
segment sales.

Outlook:

The  Life  Sciences  segment  is  expected  to  have  low-single-digit 
percentage  sales  growth  for  first-quarter  and  full-year  2017,  ahead  of 
forecasted market growth rates.

All Other
All  other  segments  that  do  not  meet  the  quantitative  threshold 
for  separate  reporting  have  been  grouped  as  “All  Other.”  This  group 
is  primarily  comprised  of  the  results  of  Corning’s  Pharmaceutical 

Technologies  business,  our  non-LCD  glass  business,  new  product  lines 
and development projects, as well as certain corporate investments such 
as Eurokera and Keraglass equity affiliates.

2016 vs. 2015
The increase in net sales of this segment in the year ended December 31, 
2016 reflects the impact of an acquisition in the Corning Pharmaceutical 
Technologies  business  completed  in  the  fourth  quarter  of  2015  and 
an  increase  in  sales  in  our  emerging  businesses.  The  increase  in  the 
net  loss  of  this  segment  was  driven  by  asset  write-offs  in  emerging 
businesses, offset slightly by the addition of the Corning Pharmaceutical 
Technologies business net income.

2015 vs. 2014
The increase in net sales of this segment in the year ended December 31, 
2015 reflects the impact of an acquisition in the Corning Pharmaceutical 
Technologies business completed in the fourth quarter of 2015 and an 
increase in sales in our emerging businesses. The slight increase in the 
net loss of this segment was driven by a goodwill impairment loss of $29 
million, offset by higher net income in the pharmaceutical technologies 
and Corning Precision Materials’ non-LCD glass businesses.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Liquidity and Capital Resources

Financing and Capital Structure
The following items impacted Corning’s financing and capital structure 
during 2016 and 2015:

2016

• In  the  third  quarter  of  2016,  Corning’s  Board  of  Directors  approved 
a  $1  billion  increase  to  our  commercial  paper  program,  raising  it 
to  $2  billion.  If  needed,  this  program  is  supported  by  our  $2  billion 
revolving  credit  facility  that  expires  in  2019.  Corning  did  not  have 
outstanding commercial paper at December 31, 2016.

2015

• In  the second quarter of 2015, we issued $375 million of 1.50% senior 
unsecured notes that mature on May 8, 2018 and $375 million of 2.90% 
senior unsecured notes that mature on May 15, 2022. The net proceeds 
of  $745  million  will  be  used  for  general  corporate  purposes. We  can 
redeem  these notes at any  time, subject  to certain customary  terms 
and conditions.

Common Stock Dividends
On February 3, 2016, Corning’s Board of Directors declared a 12.5% increase 
in  the  Company’s  quarterly  common  stock  dividend,  which  increased 
the quarterly dividend from $0.12 to $0.135 per share of common stock, 
beginning with the dividend to be paid in the first quarter of 2016. The 
Company paid four quarterly dividends of $0.135 during the year ended 
December 31, 2016 and paid four quarterly dividends of $0.12 during the 
year ended December 31, 2015.

On February 1, 2017, Corning’s Board of Directors declared a 14.8% increase 
in  the  Company’s  quarterly  common  stock  dividend,  which  increased 
the quarterly dividend from $0.135 to $0.155 per share of common stock, 
beginning with the dividend to be paid in the first quarter of 2017. This 
increase marks the sixth dividend increase since October 2011.

Fixed Rate Cumulative Convertible Preferred 
Stock, Series A
On  January  15,  2014,  Corning  designated  a  new  series  of  its  preferred 
stock  as  Fixed  Rate  Cumulative  Convertible  Preferred  Stock,  Series  A, 
par value $100 per share, and issued 1,900 shares of Preferred Stock at 
an  issue  price  of  $1  million  per  share,  for  an  aggregate  issue  price  of 
$1.9  billion,  to  Samsung  Display  in  connection  with  the  acquisition  of 
its  equity  interests  in  Samsung  Corning  Precision  Materials.  Corning 
also issued to Samsung Display an additional 400 shares of Fixed Rate 
Cumulative  Convertible  Preferred  Stock  at  closing,  for  an  aggregate 
issue price of $400 million in cash.

Dividends  on  the  Preferred  Stock  are  cumulative  and  accrue  at  the 
annual  rate  of  4.25%  on  the  per  share  issue  price  of  $1  million.  The 
dividends are payable quarterly as and when declared by the Company’s 
Board of Directors. The Preferred Stock ranks senior to our common stock 

with respect to payment of dividends and rights upon liquidation. The 
Preferred Stock is not redeemable except in the case of a certain deemed 
liquidation  event,  the  occurrence  of  which  is  under  the  control  of  the 
Company. The Preferred Stock is convertible at the option of the holder 
and  the  Company  upon  certain  events,  at  a  conversion  rate  of  50,000 
shares  of  Corning’s  common  stock  per  one  share  of  Preferred  Stock, 
subject to certain anti-dilution provisions. As of December 31, 2016, the 
Preferred  Stock  has  not  been  converted,  and  none  of  the  anti-dilution 
provisions have been triggered. Following the seventh anniversary of the 
closing of the acquisition of Samsung Corning Precision Materials, the 
Preferred Stock will be convertible, in whole or in part, at the option of 
the holder. The Company has  the right, at its option,  to cause some or 
all of the shares of Preferred Stock to be converted into Common Stock, 
if, for 25 trading days (whether or not consecutive) within any period of 
40 consecutive trading days, the closing price of Common Stock exceeds 
$35 per share. If  the aforementioned right becomes exercisable before 
the seventh anniversary of the closing, the Company must first obtain 
the written approval of the holders of a majority of the Preferred Stock 
before exercising its conversion right. The Preferred Stock does not have 
any voting rights except as may be required by law.

Customer Deposits
In  December  2015,  Corning  announced  that  with  the  support  of  the 
Hefei government it will locate a Gen 10.5 glass manufacturing facility 
in the Hefei XinZhan General Pilot Zone in Anhui Province, China. Glass 
substrate production from the new facility is expected to support mass 
production of LCD panels for large-size televisions beginning in 2018.

As part of this investment, Corning and a Chinese customer have entered 
into a long-term supply agreement that commits the customer to the 
purchase of Gen 10.5 glass substrates from the Corning manufacturing 
facility  in  Hefei.  This  agreement  stipulates  that  the  customer  will 
provide a non-refundable cash deposit in the amount of approximately 
$400 million to Corning to secure rights to an amount of glass that is 
produced by Corning over  the next 10 years. Corning has collected  the 
full amount of this deposit, adjusted for foreign exchange movements, 
receiving  $185  million  of  this  deposit  in  2016  and  $197  million  in  2015. 
As  glass  is  shipped  to  the  customer,  Corning  will  recognize  revenue 
and  issue  credit  memoranda  to  reduce  the  amount  of  the  customer 
deposit  liability,  which  are  applied  against  customer  receivables 
resulting from the sale of glass. In 2016 and 2015, there were no credit 
memoranda issued.

Capital Spending
Capital spending totaled $1.1 billion in 2016, slightly below the amount 
spent  in  2015.  Spending  in  our  Display  Technologies  and  Optical 
Communications segments represented 41% and 22%, respectively. We 
expect  our  2017  capital  expenditures  to  be  approximately  $1.5  billion, 
driven  by  expansions  related  to  the  Gen  10.5  glass  manufacturing 
facility  in  China,  the  addition  of  capacity  to  support  the  new  gas-
particulate filters business in the Environmental Technologies segment 
and  investment  to  support  general  business  growth  in  the  Optical 
Communications and Specialty Materials segments.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Cash Flows
Summary of cash flow data (in millions):

Net cash provided by operating activities

Net cash provided by (used in) investing activities

Net cash used in financing activities

2016 vs. 2015

Net cash provided by operating activities decreased $288 million in the 
year  ended  December  31,  2016  when  compared  to  2015,  driven  largely 
by  a  decrease  in  net  income  excluding  non-cash  gains,  an  increase  in 
accounts  receivable  in  the  Optical  Communications  and  Specialty 
Materials  segments,  up  $81  and  $70  respectively,  partially  offset  by  an 
increase  in  accounts  payable  and  other  current  liabilities.  A  decrease 
of $58 million in dividends received from equity affiliates, driven by the 
strategic  realignment  of  our  ownership  interest  in  Dow  Corning,  also 
negatively impacted cash flow from operations.

Net  cash  provided  by  investing  activities  increased  substantially,  up 
$4,347 million, in the year ended December 31, 2016 when compared to 
2015, driven by $4,818 million in cash received upon the realignment of 
Dow Corning, a decrease of $120 million in capital expenditures and a 
decrease  of  $399  million  in  acquisition  spending,  partially  offset  by  a 
decrease  of  $452  million  in  realized  gains  on  our  translated  earnings 
contracts.

Net  cash  used  in  financing  activities  in  the  year  ended  December  31, 
2016  increased  $2,703  when  compared  to  2015,  driven  by  an  increase 
of $999 million in share repurchases, the repayment of $481 million of 
commercial paper outstanding in 2015 and the absence of cash received 
from the issuance of long-term debt in the amount of $745 million in the 
third quarter of 2015.

2015 vs. 2014

Net  cash  provided  by  operating  activities  decreased  significantly 
in  the  year  ended  December  31,  2015,  when  compared  to  the  same 
period  last  year,  due  to  the  absence  of  a  special  one-time  dividend  of 
$1,574 million received from Samsung Corning Precision Materials in the 
first quarter of 2014, lower net income and cash outflows from working 
capital  movements,  offset  somewhat  by  the  receipt  of  a  $197  million 
customer  deposit  and  the  adjustment  to  net  income  related  to  gains 
on foreign currency hedges and other noncash operating adjustments. 
Cash outflows from working capital movements were largely driven by 
an  increase  in  variable  compensation  paid  in  2015  and  an  increase  in 
inventory in the Display Technologies segment.

Net  cash  used  in  investing  activities  decreased  in  the  year  ended 
December 31, 2015, when compared to the same period last year, due to 
net liquidations of short-term investments and an increase in realized 
gains  on  our  translated  earnings  contracts,  offset  by  higher  capital 
spending and several acquisitions that were completed in 2015.

Net cash used in financing activities in the year ended December 31, 2015 
increased slightly when compared  to  the same period last year, driven 
by  an  increase  in  share  repurchases  and  the  absence  of  cash  received 
from  the issuance of preferred stock, offset by proceeds received from 
the issuance of long-term debt and commercial paper.

Defined Benefit Pension Plans
We have defined benefit pension plans covering certain domestic and 
international  employees.  Our  largest  single  pension  plan  is  Corning’s 
U.S.  qualified  plan.  At  December  31,  2016,  this  plan  accounted  for  77% 
of  our  consolidated  defined  benefit  pension  plans’  projected  benefit 
obligation and 86% of the related plans’ assets.

We  have  historically  contributed  to  the  U.S.  qualified  pension  plan  on 
an  annual  basis  in  excess  of  the  IRS  minimum  requirements.  In  2016, 
we  made  voluntary  cash  contributions  of  $73  million  to  our  domestic 
defined  benefit  pension  plan  and  $16  million  to  our  international 
pension  plans.  In  2015,  we  made  voluntary  cash  contributions  of 
$65 million to our domestic defined benefit pension plan and $35 million 
to our international pension plans. We are not subject to any mandatory 
contributions  in  2017,  and  do  not  anticipate  making  voluntary  cash 
contributions  to  our  U.S.  qualified  pension  plan.  We  anticipate 
contributing up to $23 million to our international pension plans in 2017.

Refer  to  Note  13  (Employee  Retirement  Plans)  to  the  Consolidated 
Financial Statements for additional information.

Restructuring
For the year ended December 31, 2016, we recorded charges of $77 million 
for  employee  related  costs,  asset  disposals,  and  exit  costs  associated 
with  some  minor  restructuring  activities  in  all  of  the  segments  with 
total cash expenditures of approximately $12 million.

For  the  year  ended  December  31,  2015,  we  did  not  record  significant 
restructuring, 
impairment  and  other  charges  or  reversals.  Cash 
expenditures for restructuring activities were $40 million.

For the year ended December 31, 2014, we recorded charges of $71 million 
for workforce reductions, asset disposals and write-offs, and exit costs for 
restructuring  activities  with  total  cash  expenditures  of  approximately 
$39 million.

Management Assessment of Liquidity
We ended the fourth quarter of 2016 with approximately $5.3 billion of 
cash  and  cash  equivalents.  Our  cash  and  cash  equivalents  are  held  in 
various locations throughout the world and are generally unrestricted. 
Although  approximately  62%  of  the  consolidated  amount  was  held 
outside  of  the  United  States  at  December  31,  2016,  we  have  sufficient 
U.S. liquidity, including borrowing capacity, to fund foreseeable U.S. cash 
needs  without  requiring  the  repatriation  of  foreign  cash.  We  utilize 
a  variety  of  financing  strategies  to  ensure  that  our  worldwide  cash  is 
available in the locations in which it is needed.

It  is  our  policy  to  manage  our  exposure  to  changes  in  interest  rates. 
To  manage  interest  rate  exposure,  the  Company,  from  time  to  time, 
enters  into  interest  rate  swap  agreements.  We  are  currently  party  to 
two  interest  rate  swaps  that  are  designated  as  fair  value  hedges  and 
economically exchange a notional amount of $550 million of previously 
issued fixed rate long-term debt to floating rate debt. Under the terms 
of the swap agreements, we pay the counterparty a floating rate that is 
indexed to the one-month LIBOR rate.

Corning  also  has  a  commercial  paper  program  pursuant  to  which  we 
may  issue  short-term,  unsecured  commercial  paper  notes.  On  July  20, 
2016, Corning’s Board of Directors approved an increase to the allowable 
maximum  aggregate  principal  amount  outstanding  at  any  time  from 
$1  billion  to  $2  billion.  Under  this  program,  the  Company  may  issue 
the  notes  from  time  to  time  and  will  use  the  proceeds  for  general 
corporate purposes. The Company’s $2 billion revolving credit facility is 
available to support obligations under the commercial paper program, 
if  needed.  Corning  did  not  have  outstanding  commercial  paper  at 
December 31, 2016.

Share Repurchases
During  2014,  Corning  repurchased  98.1  shares  for  approximately 
$2 billion through an accelerated share repurchase agreement and open 
market repurchases as part of the $2 billion share repurchase program 
announced on October 22, 2013 and made effective concurrent with the 
closing of Corning’s acquisition of Samsung Corning Precision Materials 
on January 15, 2014 (the “March 2014 Repurchase Program”).

During 2015, Corning repurchased 167 million shares for approximately 
$3.25  billion  through  an  accelerated  share  repurchase  agreement  and 
open  market  repurchases  as  part  of  a  repurchase  program  authorized 
by Corning’s Board of Directors in December 2014 (the “December 2014 
Repurchase Program”) and repurchase programs authorized by Corning’s 
Board of Directors in July 2015 and October 2015 (the “2015 Repurchase 
Programs”).

During 2016, Corning repurchased 197.1 million shares for approximately 
$4.2  billion  through  an  accelerated  share  repurchase  agreement  and 
open market repurchases as part of the 2015 Repurchase Programs.

Refer  to  Note  17  (Shareholders’  Equity)  to  the  Consolidated  Financial 
Statements for additional information.

Other
We  complete  comprehensive  reviews  of  our  significant  customers 
and  their  creditworthiness  by  analyzing  their  financial  strength 
at  least  annually  or  more  frequently  for  customers  where  we  have 
identified  a  measure  of  increased  risk.  We  closely  monitor  payments 
and  developments  which  may  signal  possible  customer  credit  issues. 
We currently have not identified any potential material impact on our 
liquidity resulting from customer credit issues.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Our major source of funding for 2017 and beyond will be our operating 
cash  flow  and  our  existing  balances  of  cash  and  cash  equivalents 
and  proceeds  from  any  issuances  of  debt.  We  believe  we  have 
sufficient  liquidity  for  the  next  several  years  to  fund  operations,  share 
repurchase programs, acquisitions, the asbestos litigation, research and 
development,  capital  expenditures,  scheduled  debt  repayments  and 
dividend payments.

Corning also has access to a $2 billion unsecured committed revolving 
credit  facility.  This  credit  facility  includes  a  leverage  ratio  financial 
covenant.  The  required  leverage  ratio,  which  measures  debt  to  total 
capital,  is  a  maximum  of  50%.  At  December  31,  2016,  our  leverage 
using  this  measure  was  18%  and  we  are  in  compliance  with  the 
financial covenant.

Our  debt  instruments  contain  customary  event  of  default  provisions, 
which  allow  the  lenders  the  option  of  accelerating  all  obligations 
upon  the  occurrence  of  certain  events.  In  addition,  some  of  our  debt 
instruments  contain  a  cross  default  provision,  whereby  an  uncured 
default  in  excess  of  a  specified  amount  on  one  debt  obligation  of  the 
Company, also would be considered a default under the terms of another 
debt instrument. As of December 31, 2016, we were in compliance with 
all such provisions.

Management is not aware of any known trends or any known demands, 
commitments,  events  or  uncertainties  that  will  result  in  or  that  are 
reasonably  likely  to  result  in  a  material  increase  or  decrease  in  our 
liquidity.  In  addition,  other  than  items  discussed,  there  are  no  known 
material trends, favorable or unfavorable, in our capital resources and no 
expected material changes in the mix and relative cost of such resources.

Translated Earnings Contracts
In the first quarter of 2013, Corning executed a series of purchased collars 
that expired quarterly across a two-year period to hedge its translation 
exposure  resulting  from  movements  in  the  Japanese  yen  against  the 
U.S.  dollar.  Beginning  in  the  second  quarter  of  2013  and  continuing 
throughout 2015, Corning entered into a series of zero cost average rate 
collars  and  average  rate  forwards  to  hedge  the  translation  impact  of 
Japanese  yen  on  Corning’s  projected  2015,  2016  and  2017  net  income. 
Additionally,  in  January  2016,  Corning  extended  its  foreign  exchange 
hedging  program  to  hedge  a  significant  portion  of  its  projected  yen 
exposure for the period 2018 through 2022. In the year ended December 
31, 2016, we recorded a pre-tax net loss of $459 million, and in the years 
ended  December  31,  2015  and  2014,  we  recorded  pre-tax  net  gains  of 
$113  million  and  $1,406  million,  respectively,  related  to  changes  in  the 
fair  value  of  these  derivative  instruments.  Included  in  these  amounts 
are  realized  gains  of  $207  million,  $686  million  and  $280  million, 
respectively. The gross notional value outstanding for purchased collars 
and average rate forwards which hedge our exposure  to  the Japanese 
yen at December 31, 2016, 2015 and 2014 was $14.9 billion, $8.3 billion and 
$9.8 billion, respectively.

We  have  entered  into  zero-cost  collars  and  average  rate  forwards  to 
hedge our translation exposure resulting from movements in the South 
Korean  won  and  its  impact  on  our  net  earnings.  In  the  year  ended 
December 31, 2016, we recorded a pre-tax net gain of $7 million, and the 
years ended December 31, 2015 and 2014, we recorded a pre-tax net loss 
of $36 million and $37 million, respectively, related to changes in the fair 
value of these instruments. Included in these amounts are realized losses 
of $7 million, $33 million and $6 million, respectively. These instruments 
had a gross notional value outstanding at December 31, 2016, 2015 and 
2014 of $1.2 billion, $3.3 billion and $2.3 billion, respectively.

We  have  entered  into  a  portfolio  of  zero-cost  collars  and  average 
rate  forwards  to  hedge  against  our  euro  translation  exposure.  In  the 
fourth quarter of 2016, the zero-cost collars expired. In the years ended 
December 31 2016 and 2015, we recorded net pre-tax gains of $15 million 
and $3 million, respectively. At December 31, 2016, the euro-denominated 
average rate forwards had a gross notional amount of $278 million, and 
at December 31, 2015, the zero-cost collars and average rate forwards had 
a gross notional value of $345 million.

In 2016, we entered into a portfolio of average rate forwards  to hedge 
against  our  translation  exposure  resulting  from  movements  in  the 
Chinese  yuan  and  the  New Taiwan  dollar  (“TWD”). These  instruments 
begin settling in the first quarter of 2017. In the year ended December 31 
2016, we recorded a net pre-tax unrealized loss of $11 million on the yuan-
denominated  translation  hedges.  At  December  31,  2016,  the  yuan-
denominated  average  rate  forwards  had  a  gross  notional  amount  of 
$275 million, and  the TWD average rate forwards had a gross notional 
value of $56 million.

These purchased collars, zero-cost collars, zero cost average rate collars 
and  average  rate  forwards  are  not  designated  as  accounting  hedges, 
and changes in their fair value are recorded in earnings in the translated 
earnings  contract  (loss)  gain,  net  line  of  the  Consolidated  Statements 
of Income.

Off Balance Sheet Arrangements
Off balance sheet arrangements are transactions, agreements, or other 
contractual  arrangements  with  an  unconsolidated  entity  for  which 
Corning  has  an  obligation  to  the  entity  that  is  not  recorded  in  our 
consolidated financial statements.

Corning’s off balance sheet arrangements include guarantee contracts. 
At the time a guarantee is issued, the Company is required to recognize 
a liability for the fair value or market value of the obligation it assumes. 
In  the  normal  course  of  our  business,  we  do  not  routinely  provide 
significant  third-party  guarantees.  Generally,  third-party  guarantees 
provided by Corning are limited to certain financial guarantees, including 
stand-by letters of credit and performance bonds, and the incurrence of 
contingent liabilities in the form of purchase price adjustments related 
to attainment of milestones. These guarantees have various terms, and 
none of these guarantees are individually significant.

Refer to Note 14 (Commitments, Contingencies and Guarantees) to the 
Consolidated Financial Statements for additional information.

For  variable  interest  entities,  we  assess  the  terms  of  our  interest  in 
each entity to determine if we are the primary beneficiary. The primary 
beneficiary  of  a  variable  interest  entity  is  the  party  that  absorbs  a 
majority of the entity’s expected losses, receives a majority of its expected 
residual returns, or both, as a result of holding variable interests, which 
are the ownership, contractual, or other pecuniary interests in an entity 
that  change  with  changes  in  the  fair  value  of  the  entity’s  net  assets 
excluding variable interests.

Corning has identified eleven entities that qualify as a variable interest 
entity. These  entities  are  not  considered  to  be  significant  to  Corning’s 
consolidated statements of position.

Corning  does  not  have  retained  interests  in  assets  transferred  to  an 
unconsolidated  entity  that  serve  as  credit,  liquidity  or  market  risk 
support to that entity.

(1)  At December 31, 2016, $39 million of the $51 million was included in other accrued liabilities on our consolidated balance sheets.

(2) Capital expenditure obligations primarily reflect amounts associated with our capital expansion activities.

(3) Total debt above is stated at maturity value, and excludes interest rate swap gains/losses and bond discounts.

(4) The estimate of interest payments assumes interest is paid through the date of maturity or expiration of the related debt, based upon stated rates 

in the respective debt instruments.

(5)  At December 31, 2016, $48 million was included on our balance sheet related to uncertain tax positions. Of this amount, we are unable to estimate 

when any of that amount will become payable.

(6) Purchase obligations are enforceable and legally binding obligations which primarily consist of raw material and energy-related take-or-pay contracts.

(7)  See Note 7 (Investments) to the Consolidated Financial Statements for additional details.

We are required, at the time a guarantee is issued, to recognize a liability 
for  the  fair  value  or  market  value  of  the  obligation  it  assumes.  In  the 
normal course of our business, we do not routinely provide significant 
third-party  guarantees.  Generally,  third-party  guarantees  provided  by 
Corning  are  limited  to  certain  financial  guarantees,  including  stand-
by  letters  of  credit  and  performance  bonds,  and  the  incurrence  of 

contingent liabilities in the form of purchase price adjustments related 
to attainment of milestones. These guarantees have various terms, and 
none of these guarantees are individually significant.

We  believe  a  significant  majority  of  these  guarantees  and  contingent 
liabilities will expire without being funded.

Environment

Corning  has  been  named  by  the  Environmental  Protection  Agency 
(the Agency) under the Superfund Act, or by state governments under 
similar  state  laws,  as  a  potentially  responsible  party  for  17  active 
hazardous  waste  sites.  Under  the  Superfund  Act,  all  parties  who  may 
have contributed any waste to a hazardous waste site, identified by the 
Agency,  are  jointly  and  severally  liable  for  the  cost  of  cleanup  unless 
the  Agency  agrees  otherwise.  It  is  Corning’s  policy  to  accrue  for  its 
estimated liability related to Superfund sites and other environmental 
liabilities related to property owned by Corning based on expert analysis 

and  continual  monitoring  by  both  internal  and  external  consultants. 
At  December  31,  2016  and  2015,  Corning  had  accrued  approximately 
$43 million (undiscounted) and $37 million (undiscounted), respectively, 
for  its  estimated  liability  for  environmental  cleanup  and  related 
litigation. Based upon the information developed to date, management 
believes  that  the  accrued  reserve  is  a  reasonable  estimate  of  the 
Company’s liability and that the risk of an additional loss in an amount 
materially higher than that accrued is remote.

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Critical Accounting Estimates

The preparation of financial statements requires us to make estimates 
and assumptions  that affect amounts reported  therein. The estimates 
that  required  us  to  make  difficult,  subjective  or  complex  judgments, 
including future projections of performance and relevant discount rates, 
are set forth below.

Impairment of assets held for use
We  are  required  to  assess  the  recoverability  of  the  carrying  value  of 
long-lived assets when an indicator of impairment has been identified. 
We  review  our  long-lived  assets  in  each  quarter  to  assess  whether 
impairment  indicators  are  present.  We  must  exercise  judgment  in 
assessing whether an event of impairment has occurred.

Manufacturing equipment includes certain components of production 
equipment that are constructed of precious metals, primarily platinum 
and rhodium. These metals are not depreciated because they have very 
low  physical  losses  and  are  repeatedly  reclaimed  and  reused  in  our 
manufacturing process over a very long useful life. Precious metals are 
reviewed for impairment as part of our assessment of long-lived assets. 
This  review  considers  all  of  the  Company’s  precious  metals  that  are 
either  in  place  in  the  production  process;  in  reclamation,  fabrication, 
or  refinement  in  anticipation  of  re-use;  or  awaiting  use  to  support 
increased  capacity.  Precious  metals  are  only  acquired  to  support  our 
operations  and  are  not  held  for  trading  or  other  non-manufacturing 
related purposes.

Examples  of  events  or  circumstances  that  may  be  indicative  of 
impairments include, but are not limited to:

• A significant decrease in the market price of an asset;

• A  significant  change  in  the  extent  or  manner  in  which  a  long-lived 

asset is being used or in its physical condition;

• A significant adverse change in legal factors or in the business climate 
that could affect the value of the asset, including an adverse action or 
assessment by a regulator;

• An  accumulation  of  costs  significantly  in  excess  of  the  amount 

originally expected for the acquisition or construction of an asset;

• A  current-period  operating  or  cash  flow  loss  combined  with  a 
history  of  operating  or  cash  flow  losses  or  a  projection  or  forecast 
that  demonstrates  continuing  losses  associated  with  the  use  of  an 
asset; and

• A current expectation that, more likely than not, an asset will be sold 
or otherwise disposed of significantly before the end of its previously 
estimated useful life.

For purposes of recognition and measurement of an impairment loss, a 
long-lived asset or assets is grouped with other assets and liabilities at 
the lowest level for which identifiable cash flows are largely independent 
of  the  cash  flows  of  other  assets  and  liabilities.  We  must  exercise 
judgment in assessing the lowest level for which identifiable cash flows 
are largely independent of the cash flows of other assets and liabilities. 
For the majority of our reportable segments, we concluded that locations 
or businesses which share production along the supply chain must be 
combined in order to appropriately identify cash flows that are largely 
independent of the cash flows of other assets and liabilities.

For  long-lived  assets,  when  impairment  indicators  are  present,  we 
compare  estimated  undiscounted  future  cash  flows,  including  the 
eventual disposition of  the asset group at market value,  to  the assets’ 
carrying  value  to  determine  if  the  asset  group  is  recoverable.  This 
assessment  requires  the  exercise  of  judgment  in  assessing  the  future 
use of and projected value to be derived from the assets to be held and 
used. Assessments also consider changes in asset utilization, including 

the  temporary  idling  of  capacity  and  the  expected  timing  for  placing 
this  capacity  back  into  production.  If  there  is  an  impairment,  a  loss  is 
recorded  to  reflect  the  difference  between  the  assets’  fair  value  and 
carrying  value.  This  may  require  judgment  in  estimating  future  cash 
flows and relevant discount rates and residual values in estimating the 
current fair value of the impaired assets to be held and used.

For an asset group that fails the test of recoverability, the estimated fair 
value  of  long-lived  assets  is  determined  using  an  “income  approach” 
that starts with  the forecast of all  the expected future net cash flows 
including the eventual disposition at market value of long-lived assets, 
and also considers the fair market value of all precious metals. We assess 
the recoverability of the carrying value of long-lived assets at the lowest 
level  for  which  identifiable  cash  flows  are  largely  independent  of  the 
cash flows of other assets and liabilities. If there is an impairment, a loss 
is recorded  to reflect  the difference between  the assets’ fair value and 
carrying value. Our estimates are based upon our historical experience, 
our commercial relationships, and available external information about 
future  trends. We  believe  fair  value  assessments  are  most  sensitive  to 
market  growth  and  the  corresponding  impact  on  volume  and  selling 
prices and that these are also more subjective than manufacturing cost 
and other assumptions. The Company believes its current assumptions 
and estimates are reasonable and appropriate.

At  December  31,  2016  and  December  31,  2015,  the  carrying  value  of 
precious metals was higher than the fair market value by $890 million 
and $976 million, respectively. The majority of these precious metals are 
utilized by the Display Technologies and Specialty Materials segments. 
Corning  believes  these  precious  metal  assets  to  be  recoverable  due  to 
the  significant  positive  cash  flow  in  both  segments. The  potential  for 
impairment exists in the future if negative events significantly decrease 
the  cash  flow  of  these  segments.  Such  events  include,  but  are  not 
limited to, a significant decrease in demand for products or a significant 
decrease  in  profitability  in  our  Display  Technologies  or  Specialty 
Materials segments.

Impairment of Goodwill
We are required to make certain subjective and complex judgments in 
assessing  whether  an  event  of  impairment  of  goodwill  has  occurred, 
including  assumptions  and  estimates  used  to  determine  the  fair 
value  of  our  reporting  units.  We  test  for  goodwill  impairment  at  the 
reporting unit level and our reporting units are the operating segments 
or the components of operating segments which constitute businesses 
for  which  discrete  financial  information  is  available  and  is  regularly 
reviewed by segment management.

Corning  has  recorded  goodwill  in  the  Display  Technologies,  Optical 
Communications,  Specialty  Materials,  Life  Sciences  and  All  Other 
operating  segments.  On  a  quarterly  basis,  management  performs  a 
qualitative  assessment  of  factors  in  each  reporting  unit  within  these 
operating  segments  to  determine  whether  there  have  been  any 
triggering events. The  two-step impairment  test is required only if we 
conclude that it is more likely than not that a reporting unit’s fair value 
is less than its carrying amount. We perform a detailed, two-step process 
every  three  years  if  no  indicators  suggest  a  test  should  be  performed 
in the interim. We use this calculation as quantitative validation of the 
step-zero qualitative process  that is performed during  the intervening 
periods  and  does  not  represent  an  election  to  perform  the  two-step 
process in place of the step-zero review.

The following summarizes our qualitative process to assess our goodwill 
balances for impairment:

• We assess qualitative factors in each of our reporting units which carry 
goodwill to determine whether it is necessary to perform the first step 
of the two-step quantitative goodwill impairment test.

37

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

• The  following  events  and  circumstances  are  considered  when 
evaluating whether it is more likely  than not  that  the fair value of a 
reporting unit is less than its carrying amount:

–  Macroeconomic  conditions,  such  as  a  deterioration  in  general 
economic conditions, fluctuations in foreign exchange rates and/or 
other developments in equity and credit markets;

–  Market capital in relation to book value;

–  Industry and market considerations, such as a deterioration in  the 
environment  in  which  an  entity  operates,  material  loss  in  market 
share and significant declines in product pricing;

–  Cost factors, such as an increase in raw materials, labor or other costs;

–  Overall  financial  performance,  such  as  negative  or  declining  cash 

flows or a decline in actual or forecasted revenue;

assessment,  we  have  aggregated  these  two  components  into  one 
reporting  unit  based  upon  their  similar  economic  characteristics. 
On  a  quarterly  basis  in  2016,  management  performed  a  qualitative 
assessment of factors and determined there had not been any triggering 
events which would indicate that the Optical Communications reporting 
unit’s fair value is less than its carrying amount.

In addition to assessing qualitative factors each quarter, we performed 
a  quantitative  goodwill  recoverability  test  in  2015  for  this  reporting 
unit. A discount rate of 5.6% and a growth rate of 3% were used in 2015. 
The results of our impairment test indicated that the fair value of the 
reporting  unit  exceeded  its  book  value  by  a  significant  amount,  and 
as  such,  further  goodwill  impairment  testing  was  not  necessary.  We 
determined a range of discount rates between 3.6% and 7.6% and growth 
rates between 0% and 3% would not have affected our conclusion.

–  Other  relevant  entity-specific  events,  such  as  material  changes  in 

Specialty Materials

management or key personnel; and

–  Events  affecting  a  reporting  unit,  such  as  a  change  in  the 
composition  or  carrying  amount  of  its  net  assets  including 
acquisitions and dispositions.

The examples noted above are not all-inclusive, and the Company will 
consider  other  relevant  events  and  circumstances  that  affect  the  fair 
value  of  a  reporting  unit  in  determining  whether  to  perform  the  first 
step of the goodwill impairment test.

Our two-step goodwill recoverability assessment is based on our annual 
strategic planning process. This process includes an extensive review of 
expectations for the long-term growth of our businesses and forecasted 
future cash flows. Our valuation method is an “income approach” using 
a  discounted  cash  flow  model  in  which  cash  flows  anticipated  over 
several  periods,  plus  a  terminal  value  at  the  end  of  that  time  horizon, 
are discounted to their present value using an appropriate rate of return. 
Our  estimates  are  based  upon  our  historical  experience,  our  current 
knowledge  from  our  commercial  relationships,  and  available  external 
information about future trends.

Display Technologies

Goodwill for the Display Technologies segment is tested at the reporting 
unit level, which is also the operating segment level consisting of two 
components.  For  the  purposes  of  the  annual  goodwill  impairment 
assessment,  we  have  aggregated  these  two  components  into  one 
reporting  unit  based  upon  their  similar  economic  characteristics. 
On  a  quarterly  basis  in  2016,  management  performed  a  qualitative 
assessment of factors and determined there had not been any triggering 
events  which  would  indicate  that  the  Display  Technologies  reporting 
unit’s fair value is less than its carrying amount.

In addition to assessing qualitative factors each quarter, we performed 
a  quantitative  goodwill  recoverability  test  in  2015  for  this  reporting 
unit. A discount rate of 5.8% and a growth rate of 1% were used in 2015. 
The results of our impairment test indicated that the fair value of the 
reporting  unit  exceeded  its  book  value  by  a  significant  amount,  and 
as  such,  further  goodwill  impairment  testing  was  not  necessary.  We 
determined a range of discount rates between 3.8% and 7.8% and growth 
rates between 0% and 3% would not have affected our conclusion.

Optical Communications

Goodwill  for  the  Optical  Communications  segment  is  tested  at  the 
reporting unit level, which is also the operating segment level consisting 
of two components. For the purposes of the annual goodwill impairment 

Goodwill for the Specialty Materials segment is tested at the reporting 
unit level, which is one level below an operating segment, as the goodwill 
is  the  result  of  transactions  associated  with  a  certain  business  within 
this  operating  segment.  On  a  quarterly  basis  in  2016,  management 
performed a qualitative assessment of factors and determined there had 
not been any triggering events which would indicate that the Specialty 
Materials reporting unit’s fair value is less than its carrying amount.

In addition to assessing qualitative factors each quarter, we performed 
a  quantitative  goodwill  recoverability  test  in  2015  for  this  reporting 
unit. A discount rate of 5.8% and a growth rate of 3% were used in 2015. 
The results of our impairment test indicated that the fair value of the 
reporting  unit  exceeded  its  book  value  by  a  significant  amount,  and 
as  such,  further  goodwill  impairment  testing  was  not  necessary.  We 
determined a range of discount rates between 3.8% and 7.8% and growth 
rates between 0% and 3% would not have affected our conclusion.

Life Sciences

Goodwill  for  the  Life  Sciences  segment  is  tested  at  the  reporting  unit 
level, which is also the operating segment level. On a quarterly basis in 
2016, management performed a qualitative assessment of factors and 
determined  there  had  not  been  any  triggering  events  which  would 
indicate that the Life Sciences reporting unit’s fair value is less than its 
carrying amount.

In addition to assessing qualitative factors each quarter, we performed a 
quantitative goodwill recoverability test in 2015 for this reporting unit. A 
discount rate of 6% and a growth rate of 3% were used in 2015. The results 
of our impairment test indicated that the fair value of the reporting unit 
exceeded  its  book  value  by  a  significant  amount,  and  as  such,  further 
goodwill impairment testing was not necessary. We determined a range 
of discount rates between 4% and 8% and growth rates between 0% and 
3% would not have affected our conclusion.

All Other

All  Other  segment  is  comprised  of  various  operating  segments  and 
corporate  investments  that  do  not  meet  the  quantitative  threshold 
for  separate  reporting.  Goodwill  for  the  All  Other  segment  is  tested 
at  the  reporting  unit  level,  which  is  also  the  operating  segment  level. 
For  the  purposes  of  the  annual  goodwill  impairment  assessment,  we 
have  identified  two  reporting  units  in  this  segment  that  require  an 
assessment of their goodwill. On a quarterly basis in 2016, management 
performed  a  qualitative  assessment  of  factors  and  determined  there 
had  not  been  any  triggering  events  which  would  indicate  that  the 
reporting units’ fair value is less than the carrying amount.

38

CORNING INCORPORATED - 2016 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

In addition  to assessing qualitative factors each quarter, we performed a 
quantitative  goodwill  recoverability  test  in  2015  for  this  reporting  unit.  A 
discount rate of 7.4% and a growth rate of 3% were used in 2015. The results 
of our impairment test indicated that the book value of one of the reporting 
units exceeded its fair value by  80%. We determined a range of discount 
rates between 5.4% and 9.4% and growth rates between 0% and 3% would 
not have affected our conclusion. Corning concluded that a Step 2 analysis 
was required to measure the impairment loss for this reporting unit.

Our  Step  2  test  consisted  of  identifying  the  underlying  net  assets  in  the 
reporting  unit,  allocating  the  implied  purchase  price  to  the  asset  and 
liabilities of the reporting unit and the calculation of the implied fair value of 
goodwill and the resulting impairment loss. In December 2015, we recorded 
a goodwill impairment loss of $29 million related to this reporting unit.

Restructuring charges and impairments 
resulting from restructuring actions
We  are  required  to  assess  whether  and  when  a  restructuring  event  has 
occurred  and  in  which  periods  charges  related  to  such  events  should  be 
recognized. We must estimate costs of plans  to restructure including, for 
example, employee termination costs. Restructuring charges require us to 
exercise judgment about the expected future of our businesses, of portions 
thereof,  their  profitability,  cash  flows  and  in  certain  instances  eventual 
outcome. The judgment involved can be difficult, subjective and complex in 
a number of areas, including assumptions and estimates used in estimating 
the future profitability and cash flows of our businesses.

Restructuring events often give rise to decisions to dispose of or abandon 
certain assets or asset groups which, as a result, require impairment. We 
are required to carry assets to be sold or abandoned at the lower of cost 
or fair value. We must exercise judgment in assessing the fair value of 
the assets to be sold or abandoned.

Income taxes
We  are  required  to  exercise  judgment  about  our  future  results  in 
assessing  the  realizability  of  our  deferred  tax  assets.  Inherent  in  this 
estimation process is the requirement for us to estimate future book and 
taxable  income  and  possible  tax  planning  strategies. These  estimates 
require us to exercise judgment about our future results, the prudence 
and  feasibility  of  possible  tax  planning  strategies,  and  the  economic 
environments in which we do business. It is possible that actual results 
will differ from assumptions and require adjustments to allowances.

Corning  accounts  for  uncertain  tax  positions  in  accordance  with  FASB 
ASC Topic 740, Income Taxes. As required under FASB ASC Topic 740, we 
only  record  tax  benefits  for  technical  positions  that  we  believe  have 
a  greater  than  50%  likelihood  of  being  sustained  on  their  technical 
merits and then only to the extent of the amount of tax benefit that is 
greater than 50% likely of being realized upon settlement. In estimating 
these amounts, we must exercise judgment around factors such as the 
weighting of the tax law in our favor, the willingness of a tax authority 
to aggressively pursue a particular position, or alternatively, consider a 
negotiated compromise, and our willingness to dispute a tax authorities 
assertion  to  the  level  of  appeal  we  believe  is  required  to  sustain  our 
position. As a result, it is possible that our estimate of the benefits we 
will  realize  for  uncertain  tax  positions  may  change  when  we  become 
aware of new information affecting these judgments and estimates.

Equity method investments
On  May  31,  2016,  Corning  completed  the  strategic  realignment  of 
its  equity  investment  in  Dow  Corning  pursuant  to  the  Transaction 
Agreement  announced  on  December  10,  2015.  Under  the  terms  of  the 
Transaction Agreement, Corning exchanged with Dow Corning its 50% 

stock interest in Dow Corning for 100% of the stock of a newly formed 
entity, which holds an equity interest in Hemlock Semiconductor Group 
and approximately $4.8 billion in cash.

The equity in earnings line on our income statement for the year ended 
December 31, 2016 reflects both the equity earnings from the silicones and 
polysilicones (Hemlock Semiconductor) businesses of Dow Corning from 
January 1, 2016 through May 31, 2016, the closing date of the Transaction 
Agreement,  and  seven  months  of  equity  earnings  from  Hemlock 
Semiconductor Group. Prior to the realignment of Dow Corning, equity 
earnings from the Hemlock Semiconductor business were reported on 
the equity in earnings line in Corning’s income statement, net of Dow 
Corning’s 35% U.S.  tax. Additionally, Corning reported its  tax on equity 
earnings  from  Dow  Corning  on  the  tax  provision  line  on  its  income 
statement at a U.S. tax provision rate of 7%. As part of the realignment, 
Hemlock  Semiconductor  Group  was  converted  to  a  partnership.  Each 
of  the  partners  is  responsible  for  the  taxes  on  their  portion  of  equity 
earnings. Therefore, post-realignment, Hemlock Semiconductor Group’s 
equity earnings is reported before tax on the equity in earnings line and 
Corning’s tax is reported on the tax provision line.

At December 31, 2016 and 2015, the carrying value of our equity method 
investments was $269 million and $1.9 billion, respectively. We review our 
equity method investments for indicators of impairment on a periodic 
basis  or  if  events  or  circumstances  change  to  indicate  the  carrying 
amount may be other-than-temporarily impaired. When such indicators 
are  present,  we  then  perform  an  in-depth  review  for  impairment.  An 
impairment  assessment  requires  the  exercise  of  judgment  related  to 
key assumptions such as forecasted revenue and profitability, forecasted 
tax  rates,  foreign  currency  exchange  rate  movements,  terminal  value 
assumptions,  historical  experience,  our  current  knowledge  from 
our  commercial  relationships,  and  available  external  information 
about  future  trends.  As  of  December  31,  2016  and  2015,  we  have  not 
identified any instances where the carrying values of our equity method 
investments were not recoverable.

Fair value measures
As required, Corning uses two kinds of inputs to determine the fair value 
of  assets  and  liabilities:  observable  and  unobservable.  Observable  inputs 
are  based  on  market  data  or  independent  sources,  while  unobservable 
inputs are based on the Company’s own market assumptions. Once inputs 
have  been  characterized,  we  prioritize  the  inputs  used  to  measure  fair 
value into one of three broad levels. Characterization of fair value inputs is 
required  for  those  accounting  pronouncements  that  prescribe  or  permit 
fair value measurement. In addition, observable market data must be used 
when available and  the highest-and-best-use measure should be applied 
to  non-financial  assets.  Corning’s  major  categories  of  financial  assets 
and  liabilities  required  to  be  measured  at  fair  value  are  short-term  and 
long-term investments, certain pension asset investments and derivatives. 
These  categories  use  observable  inputs  only  and  are  measured  using  a 
market approach based on quoted prices in markets considered active or in 
markets in which there are few transactions.

Derivative  assets  and  liabilities  may  include  interest  rate  swaps  and 
forward exchange contracts that are measured using observable quoted 
prices for similar assets and liabilities. Included in our forward exchange 
contracts  are  foreign  currency  hedges  that  hedge  our  translation 
exposure resulting from movements in the Japanese yen, South Korean 
won,  euro,  New  Taiwan  dollar  and  Chinese  yuan.  These  contracts  are 
not  designated  as  accounting  hedges,  and  changes  in  their  fair  value 
are recorded in earnings in the translated earnings contract (loss) gain, 
net line of the Consolidated Statements of Income. In arriving at the fair 
value  of  Corning’s  derivative  assets  and  liabilities,  we  have  considered 
the  appropriate  valuation  and  risk  criteria,  including  such  factors  as 
credit risk of the relevant party to the transaction. Amounts related to 
credit risk are not material.

Refer to Note 16 (Fair Value Measurements) to the Consolidated Financial 
Statements for additional information.

Probability of litigation outcomes
We  are  required  to  make  judgments  about  future  events  that  are 
inherently  uncertain.  In  making  determinations  of  likely  outcomes 
of  litigation  matters,  we  consider  the  evaluation  of  legal  counsel 
knowledgeable  about  each  matter,  case  law,  and  other  case-specific 
issues.  See  Part  II  –  Item  3.  Legal  Proceedings  for  a  discussion  of  the 
material litigation matters we face.

Other possible liabilities
We  are  required  to  make  judgments  about  future  events  that  are 
inherently  uncertain.  In  making  determinations  of  likely  outcomes  of 
certain  matters,  including  certain  tax  planning  and  environmental 
matters, these judgments require us to consider events and actions that 
are  outside  our  control  in  determining  whether  probable  or  possible 
liabilities require accrual or disclosure. It is possible that actual results 
will differ from assumptions and require adjustments to accruals.

Pension and other postretirement employee 
benefits (OPEB)
Corning offers employee retirement plans consisting of defined benefit 
pension  plans  covering  certain  domestic  and  international  employees 
and  postretirement  plans  that  provide  health  care  and  life  insurance 
benefits for eligible retirees and dependents. The costs and obligations 
related  to  these  benefits  reflect  the  Company’s  assumptions  related 
to  general  economic  conditions  (particularly  interest  rates),  expected 
return on plan assets, rate of compensation increase for employees and 
health  care  trend  rates.  The  cost  of  providing  plan  benefits  depends 
on  demographic  assumptions 
retirements,  mortality, 
turnover  and  plan  participation. While  management  believes  that  the 
assumptions  used  are  appropriate,  differences  in  actual  experience  or 
changes  in  assumptions  may  affect  Corning’s  employee  pension  and 
other postretirement obligations, and current and future expense.

including 

Costs  for  our  defined  benefit  pension  plans  consist  of  two  elements: 
1)  on-going  costs  recognized  quarterly,  which  are  comprised  of  service 
and interest costs, expected return on plan assets and amortization of 
prior service costs; and 2) mark-to-market gains and losses outside of the 
corridor, where the corridor is equal to 10% of the greater of the benefit 
obligation or the market-related value of plan assets at the beginning of 
the year, which are recognized annually in the fourth quarter of each year. 
These gains and losses result from changes in actuarial assumptions for 
discount rates and the differences between actual and expected return 
on plan assets. Any interim remeasurements triggered by a curtailment, 
settlement  or  significant  plan  changes,  as  well  as  any  true-up  to  the 
annual valuation, are recognized as a mark-to-market adjustment in the 
quarter in which such event occurs.

Costs for our OPEB plans consist of on-going costs recognized quarterly, 
and  are  comprised  of  service  and  interest  costs,  amortization  of  prior 
service costs and amortization of actuarial gains and losses. We recognize 
the  actuarial  gains  and  losses  resulting  from  changes  in  actuarial 
assumptions for discount rates as a component of Stockholders’ Equity 
on  our  consolidated  balance  sheets  on  an  annual  basis  and  amortize 

them  into  our  operating  results  over  the  average  remaining  service 
period of employees expected to receive benefits under the plans, to the 
extent such gains and losses are outside of the corridor.

Prior to the December 31, 2015 valuation of its defined benefit pension 
and OPEB plans, Corning used the traditional, single weighted-average 
discount rate approach to develop the obligation, interest cost and service 
cost  components  of  net  periodic  benefit  cost  for  its  defined  benefit 
pension and OPEB plans. The individual spot rates from the yield curve 
are  used  in  measuring  the  pension  plan  projected  benefit  obligation 
(PBO)  or  OPEB  plan  accumulated  postretirement  benefit  obligation 
(APBO)  at  the  measurement  date. The  benefit  obligation  is  effectively 
calculated as the aggregate present value at the measurement date of 
each future benefit payment related to past service, with each payment 
discounted  using  a  spot  rate  from  a  high-quality  corporate  bond 
yield  curve  that  matches  the  duration  of  the  benefit  payment.  Under 
Corning’s traditional, single weighted-average discount rate approach, a 
single weighted-average rate is developed from the approach described 
above  and  rounded  to  the  nearest  25  basis  points.  Traditionally,  the 
weighted-average discount rate is determined at the plan measurement 
date,  based  on  the  same  projected  future  benefit  payments  used  in 
developing  the  benefit  obligation.  The  traditional  single  weighted-
average discount rate represents the constant annual rate that would be 
required to discount all future benefit payments related to past service 
from  the  date  of  expected  future  payment  to  the  measurement  date 
such that the aggregate present value equals the benefit obligation.

Beginning with  the December 31, 2015 valuation of its defined benefit 
pension  and  OPEB  plans,  Corning  changed 
its  methodology  of 
determining  the  service  and  interest  cost  components  of  net  periodic 
pension  and  other  postretirement  benefit  costs  to  a  more  granular 
approach. Under the new approach, the cash flows from each applicable 
pension  and  OPEB  plan  are  used  to  directly  calculate  the  benefit 
obligation, service cost and interest cost using the spot rates from the 
applicable yield curve.

Moving  to  a  more  granular  approach  has  a  limited  impact  on  the 
determination of the respective benefit obligations. The only impacts are 
as a result of the elimination of the rounding of the discount rate that 
occurred in the traditional approach and the use of specific cash flows 
for  Corning’s  non-qualified  pension  plans,  while  separately  applying 
the yield curve to each separate OPEB plan instead of aggregating the 
OPEB plan cash flows. This change will result in a decrease in the interest 
cost  and  service  cost  components  of  net  periodic  pension  and  OPEB 
costs.  For  the  year  ended  December  31,  2017,  net  periodic  pension  and 
OPEB  costs  will  be  lower  by  approximately  $23  million  and  $5  million, 
respectively, due to this change. For Corning’s pension plans, this change 
will increase the immediate recognition of actuarial losses (or decrease 
the immediate recognition of actuarial gains), due to Corning’s previous 
election  to  immediately  recognize  actuarial  gains  and  losses  outside 
of  the corridor. For Corning’s OPEB plans,  this change will increase  the 
accumulated other comprehensive income (AOCI) account balance due 
to the accumulation of lower actuarial gains or higher actuarial losses. 
Over time, the amortization of the actuarial losses from AOCI will begin 
to reduce the savings from the lower interest cost and service cost.

This  change  was  a  change  in  accounting  estimate  and  therefore 
was  applied  prospectively  beginning  with  the  measurement  date  of 
December 31, 2015. No restatement of prior periods is required.

The above sensitivities reflect the impact of changing one assumption 
at  a  time.  Note  that  economic  factors  and  conditions  often  affect 
multiple assumptions simultaneously and the effects of changes in key 
assumptions  are  not  necessarily  linear. These  changes  in  assumptions 
would have no effect on Corning’s funding requirements.

In addition, at December 31, 2016, a 25 basis point decrease in each spot 
rate would decrease stockholders’ equity by $117 million before tax, and 
a 25 basis point increase in each spot rate would increase stockholders’ 
equity by $111 million. In addition, the impact of greater than a 25 basis 
point decrease in each spot rate would not be proportional to the first 25 
basis point decrease in each spot rate.

The following table illustrates the sensitivity to a change in each spot rate assumption related to Corning’s U.S. OPEB plans:

The above sensitivities reflect  the impact of changing one assumption at a  time. Note  that economic factors and conditions often affect multiple 
assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear.

Share-Based Compensation
Share-based  compensation  cost  is  measured  at  the  grant  date  based 
on  the  fair  value  of  the  award  and  is  recognized  as  expense  over  the 
requisite  service  period.  Determining  the  fair  value  of  stock-based 
awards  at  the  grant  date  requires  judgment,  including  estimating 
expected dividends. In addition, judgment is also required in estimating 
the  amount  of  share-based  awards  that  are  expected  to  be  forfeited. 
If  actual  results  differ  significantly  from  these  estimates,  share-based 
compensation expense and our results of operations could be impacted.

Revenue recognition
The  Company  recognizes  revenue  when  it  is  realized  or  realizable  and 
earned. In certain instances, revenue recognition is based on estimates 
of  fair  value  of  deliverables  as  well  as  estimates  of  product  returns, 
allowances, discounts, and other factors. These estimates are supported 
by  historical  data.  Corning  also  has  contractual  arrangements  with 
certain  customers  in  which  we  recognize  revenue  on  a  completed 
contract  basis.  Revenues  under  the  completed-contract  method  are 
recognized upon substantial completion, defined as acceptance by the 
customer  and  compliance  with  performance  specifications  as  agreed 
upon in the contract, which in certain instances require estimates and 
judgments  in  determining  the  timing  of  substantial  completion  of 
the contract. While management believes  that  the estimates used are 
appropriate,  differences  in  actual  experience  or  changes  in  estimates 
may affect Corning’s future results.

CORNING INCORPORATED - 2016 Annual ReportQuantitative and Qualitative Disclosures About 
Market Risks

of $1,458 million compared to $741 million at December 31, 2015. Specific 
to  the  South  Korean  won,  a  10%  adverse  movement  in  quoted  South 
Korean won exchange rates could result in a loss in fair value of these 
instruments  of  $79  million  compared  to  $99  million  at  December  31, 
2015. The Company expects  that  these hypothetical losses from a 10% 
adverse  movement  in  quoted  foreign  currency  exchange  rates  on  the 
derivative  financial  instruments  should  largely  offset  gains  and  losses 
on the assets, liabilities and future transactions being hedged.

Because  we  derive  approximately  72%  of  our  net  sales  from  outside 
the  U.S.,  our  sales  and  net  income  could  be  affected  if  the  U.S.  dollar 
significantly  strengthens  or  weakens  against  foreign  currencies,  most 
notably the Japanese yen, South Korean won, and euro. As an example of 
the impact that changes in foreign currency exchange rates could have 
on our financial results, we compare 2016 actual sales in yen, won and 
euro transaction currencies at an average currency exchange rate during 
the year to a 10% change in the currency exchange rate. A plus or minus 
10%  movement  in  the  U.S.  dollar  –  Japanese  yen  exchange  rate  would 
result in a change to 2016 net sales of approximately $328 million. A plus 
or minus 10% movement in the U.S. dollar – South Korean won and U.S. 
dollar – euro exchange rates would result in a change to 2016 net sales 
of  approximately  $5  million  and  $80  million,  respectively. We  estimate 
that  a  plus  or  minus  10%  movement  in  the  U.S.  dollar  –  Japanese  yen 
exchange rate would result in a change to 2016 net income attributable 
to Corning Incorporated of approximately $201 million. A plus or minus 
10%  movement  in  the  U.S.  dollar  –  South  Korean  won  and  U.S.  dollar 
–  euro  exchange  rates  would  result  in  a  change  to  2016  net  income 
attributable to Corning Incorporated of approximately $65 million and 
$6 million, respectively.

Interest Rate Risk Management
It  is  our  policy  to  manage  our  exposure  to  changes  in  interest  rates. 
To  manage  interest  rate  exposure,  the  Company,  from  time  to  time, 
enters  into  interest  rate  swap  agreements.  We  are  currently  party  to 
two  interest  rate  swaps  that  are  designated  as  fair  value  hedges  and 
economically exchange a notional amount of $550 million of previously 
issued fixed rate long-term debt to floating rate debt. Under the terms 
of the swap agreements, we pay the counterparty a floating rate that is 
indexed to the one-month LIBOR rate.

We  operate  and  conduct  business  in  many  foreign  countries  and  as  a 
result  are  exposed  to  movements  in  foreign  currency  exchange  rates. 
Our exposure to exchange rates has the following effects:

• Exchange rate movements on financial instruments and transactions 

denominated in foreign currencies that impact earnings; and

• Exchange  rate  movements  upon  conversion  of  net  assets  and  net 
income of foreign subsidiaries for which the functional currency is not 
the U.S. dollar, which impact our net equity.

Our most significant foreign currency exposures relate to the Japanese 
yen,  South  Korean  won,  New  Taiwan  dollar,  Chinese  yuan,  and  the 
euro.  We  seek  to  mitigate  the  impact  of  exchange  rate  movements 
in  our  income  statement  by  using  over-the-counter  (OTC)  derivative 
instruments including foreign exchange forward and option contracts. 
In  general,  these  hedges  expire  coincident  with  the  timing  of  the 
underlying foreign currency commitments and transactions.

We  are  exposed  to  potential  losses  in  the  event  of  non-performance 
by  our  counterparties  to  these  derivative  contracts.  However,  we 
minimize this risk by maintaining a diverse group of highly-rated major 
international  financial  institutions  as  our  counterparties.  We  do  not 
expect  to  record  any  losses  as  a  result  of  such  counterparty  default. 
Neither  we  nor  our  counterparties  are  required  to  post  collateral  for 
these financial instruments.

Our cash flow hedging activities utilize OTC foreign exchange forward 
contracts  to  reduce  the  risk  that  movements  in  exchange  rates  will 
adversely affect the net cash flows resulting from the sale of products 
to  foreign  customers  and  purchases  from  foreign  suppliers.  We  also 
use  OTC  foreign  exchange  forward  and  option  contracts  that  are  not 
designated  as  hedging  instruments  for  accounting  purposes.  The 
undesignated  hedges  limit  exposures  to  foreign  functional  currency 
fluctuations related to certain subsidiaries’ monetary assets, monetary 
liabilities  and  net  earnings  in  foreign  currencies.  A  significant  portion 
of the Company’s non-U.S. revenues are denominated in Japanese yen. 
When  these revenues are  translated back  to U.S. dollars,  the Company 
is  exposed  to  foreign  exchange  rate  movements  in  the  Japanese  yen. 
To protect translated earnings against movements in the Japanese yen, 
the Company has entered into a series of zero cost collars and average 
rate forwards.

We use a sensitivity analysis to assess the market risk associated with 
our foreign currency exchange risk. Market risk is defined as the potential 
change  in  fair  value  of  assets  and  liabilities  resulting  from  an  adverse 
movement  in  foreign  currency  exchange  rates.  At  December  31,  2016, 
with  respect  to  open  foreign  exchange  forward  and  option  contracts, 
and  foreign  denominated  debt  with  values  exposed  to  exchange  rate 
movements,  a  10%  adverse  movement  in  quoted  foreign  currency 
exchange rates could result in a loss in fair value of these instruments 
of  $1,618  million  compared  to  $901  million  at  December  31,  2015. 
Specific  to  the  Japanese  yen,  a  10%  adverse  movement  in  quoted  yen 
exchange rates could result in a loss in fair value of these instruments

CORNING INCORPORATED - 2016 Annual ReportManagement’s Annual Report on Internal Control Over 
Financial Reporting

Management is responsible for establishing and maintaining adequate 
disclosure  controls  and  procedures  and  adequate  internal  control  over 
financial reporting for Corning. Management is also responsible for the 
assessment  of  the  effectiveness  of  disclosure  controls  and  procedures 
and the effectiveness of internal control over financial reporting.

Disclosure controls and procedures mean controls and other procedures 
of  an  issuer  that  are  designed  to  ensure  that  information  required  to 
be disclosed by  the issuer in  the reports  that it files or submits under 
the  Exchange  Act  is  recorded,  processed,  summarized,  and  reported, 
within the time periods specified in the SEC’s rules and forms. Corning’s 
disclosure controls and procedures include, without limitation, controls 
and  procedures  designed  to  ensure  that  information  required  to 
be  disclosed  by  Corning  in  the  reports  that  it  files  or  submits  under 
the  Exchange  Act  is  accumulated  and  communicated  to  Corning’s 
management,  including  Corning’s  principal  executive  and  principal 
financial  officers,  or  other  persons  performing  similar  functions,  as 
appropriate to allow timely decisions regarding required disclosure.

Corning’s internal control over financial reporting is a process designed 
to  provide  reasonable  assurance  regarding  the  reliability  of  financial 
reporting  and  the  preparation  of  financial  statements  for  external 
purposes  in  accordance  with  accounting  principles  generally  accepted 
in the United States of America. Corning’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  Corning’s  assets; 
(ii)  provide  reasonable  assurance  that  transactions  are  recorded  as 

necessary to permit preparation of financial statements in accordance 
with  accounting  principles  generally  accepted  in  the  United  States  of 
America, and that Corning’s receipts and expenditures are being made 
only in accordance with authorizations of Corning’s management and 
directors;  and  (iii)  provide  reasonable  assurance  regarding  prevention 
or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition 
of  Corning’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 
and procedures may deteriorate.

Management conducted an evaluation of the effectiveness of the system 
of internal control over financial reporting based on  the framework in 
Internal Control – Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. Management’s 
assessment of internal control over financial reporting includes controls 
over recognition of equity earnings and equity investments by Corning. 
Internal  control  over  financial  reporting  for  Hemlock  Semiconductor 
Group is the responsibility of its management. Based on this evaluation, 
management  concluded  that  Corning’s  internal  control  over  financial 
reporting  was  effective  as  of  December  31,  2016.  The  effectiveness  of 
Corning’s  internal  control  over  financial  reporting  as  of  December  31, 
2016, has been audited by PricewaterhouseCoopers LLP, an independent 
registered  public  accounting  firm,  as  stated  in  their  report  which  is 
included herein.

CORNING INCORPORATED - 2016 Annual ReportReport of Independent Registered Public 
Accounting Firm

PricewaterhouseCoopers LLP
To the Board of Directors and Shareholders of Corning Incorporated:

In  our  opinion,  the  consolidated  financial  statements  listed  in  the 
accompanying index present fairly, in all material respects, the financial 
position  of  Corning  Incorporated  and  its  subsidiaries  at  December 
31,  2016  and  2015,  and  the  results  of  its  operations  and  its  cash  flows 
for  each  of  the  three  years  in  the  period  ended  December  31,  2016  in 
conformity with accounting principles generally accepted in the United 
States  of  America.  In  addition,  in  our  opinion,  the  financial  statement 
schedule listed in the accompanying index presents fairly, in all material 
respects,  the  information  set  forth  therein  when  read  in  conjunction 
with the related consolidated financial statements. Also in our opinion, 
the  Company  maintained,  in  all  material  respects,  effective  internal 
control over financial reporting as of December 31, 2016, based on criteria 
established in Internal Control - Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO). The Company’s management is responsible for 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  Annual  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.

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

Corning Incorporated and Subsidiary Companies

1.  Summary of Significant Accounting Policies

Organization
Corning  Incorporated  is  a  provider  of  high-performance  glass  for 
notebook computers, flat panel desktop monitors, LCD televisions, and 
other  information  display  applications;  carrier  network  and  enterprise 
network  products  for  the  telecommunications 
industry;  ceramic 
substrates  for  gasoline  and  diesel  engines  in  automotive  and  heavy 
duty vehicle markets; laboratory products for the scientific community 
and  specialized  polymer  products  for  biotechnology  applications; 
advanced  optical  materials  for  the  semiconductor  industry  and  the 
scientific community; and other technologies. In these notes, the terms 
“Corning,”  “Company,”  “we,”  “us,”  or  “our”  mean  Corning  Incorporated 
and subsidiary companies.

Basis of Presentation and Principles of 
Consolidation
Our  consolidated  financial  statements  were  prepared  in  conformity 
with  generally  accepted  accounting  principles  in  the  U.S.  and  include 
the  assets,  liabilities,  revenues  and  expenses  of  all  majority-owned 
subsidiaries over which Corning exercises control.

The  equity  method  of  accounting  is  used  for  investments  in  affiliated 
companies that are not controlled by Corning and in which our interest 
is  generally  between  20%  and  50%  and  we  have  significant  influence 
over the entity. Our share of earnings or losses of affiliated companies, 
in  which  at  least  20%  of  the  voting  securities  is  owned  and  we  have 
significant  influence  but  not  control  over  the  entity,  is  included  in 
consolidated operating results.

We use the cost method to account for our investments in companies 
that  we  do  not  control  and  for  which  we  do  not  have  the  ability  to 
exercise  significant  influence  over  operating  and  financial  policies.  In 
accordance  with  the  cost  method,  these  investments  are  recorded  at 
cost or fair value, as appropriate.

All  material  intercompany  accounts,  transactions  and  profits  are 
eliminated in consolidation.

Certain  prior  year  amounts  have  been  reclassified  to  conform  to  the 
current-year  presentation.  These  reclassifications  had  no  impact  on 
our results of operations, financial position, or changes in shareholders’ 
equity.

Samsung  Corning  Precision  Materials  Co.,  Ltd. 
(“Samsung Corning Precision Materials”)
On January 15, 2014, Corning completed a series of strategic and financial 
agreements to acquire the common shares of Samsung Corning Precision 
Materials  previously  held  by  Samsung  Display  Co.,  Ltd.  (“Samsung 
Display”). As a result of these transactions, Corning became the owner 
of 100% of the common shares of Samsung Corning Precision Materials, 
which we consolidated into our results beginning in the first quarter of 
2014. Operating under the name of Corning Precision Materials Co., Ltd. 

(“Corning Precision Materials”), the former Samsung Corning Precision 
Materials organization and operations were integrated into the Display 
Technologies segment in the first quarter of 2014.

Refer to Note 8 (Acquisitions) to the Consolidated Financial Statements 
for additional information.

Dow Corning
Prior  to  May  31,  2016,  Corning  and  Dow  Chemical  each  owned  half 
of  Dow  Corning,  an  equity  company  headquartered  in  Michigan 
that  manufactures  silicone  products  worldwide.  Dow  Corning  was 
the  majority-owner  of  HSG,  a  market  leader  in  the  production  of 
high  purity  polycrystalline  silicon  for  the  semiconductor  and  solar 
energy  industries.  On  May  31,  2016,  Corning  completed  the  strategic 
realignment  of  its  equity  investment  in  Dow  Corning  pursuant  to  the 
Transaction Agreement announced in December 2015. Under the terms 
of  the  Transaction  Agreement,  Corning  exchanged  with  Dow  Corning 
its 50% stock interest in Dow Corning for 100% of the stock of a newly 
formed entity, which holds an equity interest in HSG and approximately 
$4.8 billion in cash. Prior to realignment, HSG, a consolidated subsidiary 
of  Dow  Corning,  was  an  indirect  equity  investment  of  Corning.  Upon 
completion of the exchange, Corning now has a direct equity investment 
in HSG.

Refer to Note 7 (Investments) to the Consolidated Financial Statements 
for additional information.

Use of Estimates
The  preparation  of  financial  statements  requires  management  to 
make  estimates  and  assumptions  that  affect  amounts  reported  in 
the  consolidated  financial  statements  and  related  notes.  Significant 
estimates and assumptions in these consolidated financial statements 
include  estimates  of  fair  value  associated  with  revenue  recognition, 
restructuring charges, goodwill and long-lived asset impairment  tests, 
estimates  of  acquired  assets  and  liabilities,  estimates  of  fair  value 
of  investments,  equity  interests,  environmental  and  legal  liabilities, 
income taxes and deferred tax valuation allowances, assumptions used 
in  calculating  pension  and  other  postretirement  employee  benefit 
expenses  and  the  fair  value  of  share-based  compensation.  Due  to  the 
inherent  uncertainty  involved  in  making  estimates,  actual  results 
reported in future periods may be different from these estimates.

Revenue Recognition
Revenue for sales of goods is recognized when a firm sales agreement 
is in place, delivery has occurred and sales price is fixed or determinable 
and collection is reasonably assured. If customer acceptance of products 
is not reasonably assured, sales are recorded only upon formal customer 
acceptance.  Sales  of  goods  typically  do  not  include  multiple  product 
and/or service elements.

50

CORNING INCORPORATED - 2016 Annual ReportAt  the  time  revenue  is  recognized,  allowances  are  recorded,  with  the 
related reduction to revenue, for estimated product returns, allowances 
and price discounts based upon historical experience and related terms 
of customer arrangements. Where we have offered product warranties, 
we  also  establish  liabilities  for  estimated  warranty  costs  based  upon 
historical  experience  and  specific  warranty  provisions.  Warranty 
liabilities are adjusted when experience indicates the expected outcome 
will differ from initial estimates of the liability.

In  addition,  Corning  also  has  contractual  arrangements  with  certain 
customers  in  which  we  recognize  revenue  on  a  completed  contract 
basis.  Revenues  under  the  completed-contract  method  are  recognized 
upon  substantial  completion,  defined  as  acceptance  by  the  customer 
and  compliance  with  performance  specifications  as  agreed  upon  in 
the contract. The Company acts as a principal under the contracts, and 
recognizes  revenues  with  corresponding  cost  of  revenues  on  a  gross 
basis for the full amount of the contract.

Research and Development Costs
Research  and  development  costs  are  charged  to  expense  as  incurred. 
Research  and  development  costs  totaled  $637  million 
in  2016, 
$638 million in 2015 and $701 million in 2014.

Foreign Currency Translation and Transactions
The  determination  of  the  functional  currency  for  Corning’s  foreign 
subsidiaries  is  made  based  on  the  appropriate  economic  factors.  For 
most  foreign  operations,  the  local  currencies  are  generally  considered 
to be the functional currencies. Corning’s most significant exception is 
our Taiwanese subsidiary, which uses the Japanese yen as its functional 
currency.  For  all  transactions  denominated  in  a  currency  other  than  a 
subsidiary’s  functional  currency,  exchange  rate  gains  and  losses  are 
included in income for the period in which the exchange rates changed. 

Notes to Consolidated Financial Statements

We  recorded  foreign  currency  transaction  gains  of  $21  million  for  the 
year ended December 31, 2016, and foreign currency transaction losses 
of $22 million and $60 million for the years ended December 31, 2015 and 
2014, respectively. These amounts were recorded in the line item Other 
(expense) income, net in the consolidated statements of income.

Foreign  subsidiary  functional  currency  balance  sheet  accounts  are 
translated  at  current  exchange  rates,  and  statement  of  operations 
accounts  are  translated  at  average  exchange  rates  for  the  year. 
Translation  gains  and  losses  are  recorded  as  a  separate  component  of 
accumulated other comprehensive income in shareholders’ equity. The 
effects  of  remeasuring  non-functional  currency  assets  and  liabilities 
into  the  functional  currency  are  included  in  current  earnings,  except 
for those related to intra-entity foreign currency transactions of a long-
term investment nature, which are recorded  together with  translation 
gains and losses in accumulated other comprehensive income (loss) in 
shareholders’ equity. Upon sale or substantially complete liquidation of 
an investment in a foreign entity,  the amount of net  translation gains 
or losses that have been accumulated in other comprehensive income 
attributable  to  that  investment  are  reported  as  a  gain  or  loss  for  the 
period in which the sale or liquidation occurs.

Share-Based Compensation
Corning’s share-based compensation programs include employee stock 
option  grants,  time-based  restricted  stock  awards  and  time-based 
restricted  stock  units,  as  more  fully  described  in  Note  19  (Share-based 
Compensation) to the Consolidated Financial Statements.

The  cost  of  share-based  compensation  awards  is  equal  to  the  fair 
value  of  the  award  at  the  date  of  grant  and  compensation  expense  is 
recognized  for  those  awards  earned  over  the  vesting  period.  Corning 
estimates  the fair value of share-based awards using a multiple-point 
Black-Scholes option valuation model, which incorporates assumptions 
including expected volatility, dividend yield, risk-free rate, expected term 
and departure rates.

Cash and Cash Equivalents
Cash equivalents consist of highly liquid investments that are readily convertible into cash. We consider securities with contractual maturities of three 
months or less, when purchased, to be cash equivalents. The carrying amount of these securities approximates fair value because of the short-term 
maturity of these instruments.

and equipment, net of accumulated depreciation, in 2016, 2015 and 2014, respectively.

Allowance for Doubtful Accounts
The  Company’s  allowance  for  doubtful  accounts  is  determined  based 
on  a  variety  of  factors  that  affect  the  potential  collectability  of  the 
related  receivables,  including  length  of  time  receivables  are  past 
due,  customer  credit  ratings,  financial  stability  of  customers,  specific 

one-time events and past customer history. In addition, in circumstances 
where the Company is made aware of a specific customer’s inability to 
meet  its  financial  obligations,  a  specific  allowance  is  established.  The 
majority  of  accounts  are  individually  evaluated  on  a  regular  basis  and 
appropriate  reserves  are  established  as  deemed  appropriate  based  on 
the above criteria.

51

CORNING INCORPORATED - 2016 Annual ReportGoodwill and Other Intangible Assets
Goodwill  is  the  excess  of  cost  of  an  acquired  entity  over  the  amounts 
assigned  to  assets  acquired  and  liabilities  assumed  in  a  business 
combination.  Goodwill  relates  to  and  is  assigned  directly  to  a  specific 
reporting  unit.  Reporting  units  are  either  operating  segments  or  one 
level  below  the  operating  segment.  Impairment  testing  for  goodwill 
is done at a reporting unit level. Goodwill is reviewed for indicators of 
impairment quarterly or if an event occurs or circumstances change that 
indicate  the carrying amount may be impaired. Corning also performs 
a  detailed,  two-step  process  every  three  years  if  no  indicators  suggest 
a  test  should  be  performed  in  the  interim. We  use  this  calculation  as 
quantitative validation of the step-zero qualitative process; this process 
does not represent an election to perform the two-step process in place 
of the step-zero review.

The  qualitative  process  includes  an  extensive  review  of  expectations 
for the long-term growth of our businesses and forecasting future cash 
flows. If we are required to perform the two-step impairment analysis, 
our valuation method is an “income approach” using a discounted cash 
flow  model  in  which  cash  flows  anticipated  over  several  periods,  plus 
a  terminal  value  at  the  end  of  that  time  horizon,  are  discounted  to 
their  present  value  using  an  appropriate  rate  of  return.  Our  estimates 
are based upon our historical experience, our current knowledge from 
our commercial relationships, and available external information about 
future  trends.  If  the  fair  value  is  less  than  the  carrying  value,  a  loss  is 
recorded  to  reflect  the  difference  between  the  fair  value  and  carrying 
value.

intangible  assets 

Other 
include  patents,  trademarks,  and  other 
intangible assets acquired from an independent party. Such intangible 
assets have a definite life and are amortized on a straight-line basis over 
estimated useful lives ranging from 4 to 50 years.

Impairment of Long-Lived Assets
We  review  the  recoverability  of  our  long-lived  assets,  such  as  plant 
and  equipment  and  intangible  assets,  when  events  or  changes  in 
circumstances  occur  that  indicate  the  carrying  value  of  the  asset  or 
asset  group  may  not  be  recoverable.  When  impairment  indicators 
are  present,  we  compare  estimated  undiscounted  future  cash  flows, 
including the eventual disposition of the asset group at market value, to 
the assets’ carrying value to determine if the asset group is recoverable. 
For an asset group that fails the test of recoverability, the estimated fair 
value  of  long-lived  assets  is  determined  using  an  “income  approach” 
that starts with  the forecast of all  the expected future net cash flows 
including the eventual disposition at market value of long-lived assets, 
and also considers the fair market value of all precious metals. We assess 
the recoverability of the carrying value of long-lived assets at the lowest 
level  for  which  identifiable  cash  flows  are  largely  independent  of  the 
cash flows of other assets and liabilities. If there is an impairment, a loss 
is recorded  to reflect  the difference between  the assets’ fair value and 
carrying  value.  Refer  to  Note  2  (Restructuring,  Impairment  and  Other 
Charges) to the Consolidated Financial Statements for more detail.

Notes to Consolidated Financial Statements

Environmental Liabilities
The Company accrues for its environmental investigation, remediation, 
operating  and  maintenance  costs  when  it  is  probable  that  a  liability 
has  been  incurred  and  the  amount  can  be  reasonably  estimated.  For 
environmental  matters,  the  most  likely  cost  to  be  incurred  is  accrued 
based on an evaluation of currently available facts with respect to each 
individual  site,  current  laws  and  regulations  and  prior  remediation 
experience.  For  sites  with  multiple  potential  responsible  parties,  the 
Company  considers  its  likely  proportionate  share  of  the  anticipated 
remediation  costs  and  the  ability  of  the  other  parties  to  fulfill  their 
obligations in establishing a provision for those costs. Where no amount 
within  a  range  of  estimates  is  more  likely  to  occur  than  another,  the 
minimum amount is accrued. When future liabilities are determined to 
be  reimbursable  by  insurance  coverage,  an  accrual  is  recorded  for  the 
potential liability and a receivable is recorded related  to  the insurance 
reimbursement when reimbursement is virtually certain.

The uncertain nature inherent in such remediation and  the possibility 
that initial estimates may not reflect the final outcome could result in 
additional costs being recognized by the Company in future periods.

Inventories
Inventories  are  stated  at  the  lower  of  cost  (first-in,  first-out  basis)  or 
market.

Property, Plant and Equipment, Net of 
Accumulated Depreciation
Land,  buildings,  and  equipment, 
including  precious  metals,  are 
recorded  at  cost.  Depreciation  is  based  on  estimated  useful  lives  of 
properties using the straight-line method. Except as described in Note 
2  (Restructuring,  Impairment  and  Other  Charges)  to  the  Consolidated 
Financial  Statements  related  to  accelerated  depreciation  arising  from 
restructuring programs and Note 9 (Property, Plant and Equipment, Net 
of Accumulated Depreciation) to the Consolidated Financial Statements 
related  to  the  depletion  of  precious  metals,  the  estimated  useful  lives 
range from 10 to 40 years for buildings and 2 to 20 years for equipment.

Included  in  the  subcategory  of  equipment  are  the  following  types  of 
assets (excluding precious metals):

Asset type

Range of useful life

Computer hardware and software

Manufacturing equipment

Furniture and fixtures

Transportation equipment

3 to 7 years

2 to 15 years

5 to 10 years

3 to 20 years

Manufacturing equipment includes certain components of production 
equipment  that  are  constructed  of  precious  metals.  These  assets  are 
not  depreciated  because  they  have  very  low  physical  losses  and  are 
repeatedly  reclaimed  and  reused  in  our  manufacturing  process  over  a 
very long useful life. We treat the physical loss of precious metals in the 
manufacturing  and  reclamation  process  as  depletion  and  account  for 
these  losses  as  a  period  expense  based  on  actual  units  lost.  Precious 
metals are integral to many of our glass production processes. They are 
only acquired to support our operations and are not held for trading or 
other purposes.

CORNING INCORPORATED - 2016 Annual ReportEmployee Retirement Plans
Corning offers employee retirement plans consisting of defined benefit 
pension  plans  covering  certain  domestic  and  international  employees 
and  postretirement  plans  that  provide  health  care  and  life  insurance 
benefits for eligible retirees and dependents. The costs and obligations 
related  to  these  benefits  reflect  the  Company’s  assumptions  related 
to  general  economic  conditions  (particularly  interest  rates),  expected 
return on plan assets, rate of compensation increase for employees and 
health care trend rates. The cost of providing plan benefits depends on 
demographic  assumptions  including  retirements,  mortality,  turnover 
and plan participation.

Costs  for  our  defined  benefit  pension  plans  consist  of  two  elements: 
1)  on-going  costs  recognized  quarterly,  which  are  comprised  of  service 
and interest costs, expected return on plan assets and amortization of 
prior service costs; and 2) mark-to-market gains and losses outside of the 
corridor, where the corridor is equal to 10% of the greater of the benefit 
obligation or the market-related value of plan assets at the beginning of 
the year, which are recognized annually in the fourth quarter of each year. 
These gains and losses result from changes in actuarial assumptions for 
discount rates and the differences between actual and expected return 
on plan assets. Any interim remeasurements triggered by a curtailment, 
settlement  or  significant  plan  changes,  as  well  as  any  true-up  to  the 
annual valuation, are recognized as a mark-to-market adjustment in the 
quarter in which such event occurs.

Costs  for  our  postretirement  benefit  plans  consist  of  on-going  costs 
recognized  quarterly,  and  are  comprised  of  service  and  interest  costs, 
amortization of prior service costs and amortization of actuarial gains 
and losses. We recognize  the actuarial gains and losses resulting from 
changes in actuarial assumptions for discount rates as a component of 
Shareholders’ Equity on our consolidated balance sheets on an annual 
basis  and  amortize  them  into  our  operating  results  over  the  average 
remaining  service  period  of  employees  expected  to  receive  benefits 
under  the  plans,  to  the  extent  such  gains  and  losses  are  outside  of 
the corridor.

Refer  to  Note  13  (Employee  Retirement  Plans)  to  the  Consolidated 
Financial Statements for additional detail.

Treasury Stock
Shares  of  common  stock  repurchased  by  us  are  recorded  at  cost  as 
treasury  stock  and  result  in  a  reduction  of  Shareholders’  Equity  in  the 
consolidated balance sheets. From time to time, treasury shares may be 
reissued  as  contributions  to  our  employee  benefit  plans. When  shares 
are reissued, we use an average cost method for determining cost. The 
difference  between  the  cost  of  the  shares  and  the  reissuance  price  is 
added to or deducted from additional paid-in capital.

Income Taxes
The  Company  accounts  for  income  taxes  using  the  asset  and  liability 
method.  Under  this  method,  deferred  tax  assets  and  liabilities  are 
recognized  for  the  future  tax  consequences  attributable  to  operating 
loss  and  tax  credit  carryforwards  and  for  differences  between  the 
carrying amounts of existing assets and liabilities and their respective 
tax bases.

The  effective  income  tax  rate  reflects  our  assessment  of  the  ultimate 
outcome  of  tax  audits.  In  evaluating  the  tax  benefits  associated  with 
our various tax filing positions, we record a tax benefit for uncertain tax 
positions using the highest cumulative tax benefit that is more likely than 
not to be realized. Adjustments are made to our liability for unrecognized 
tax benefits in the period in which we determine the issue is effectively 

Notes to Consolidated Financial Statements

settled with the tax authorities, the statute of limitations expires for the 
return containing  the  tax position or when new information becomes 
available. Our liability for unrecognized tax benefits, including accrued 
penalties and interest, is included in other accrued liabilities and other 
long-term liabilities on our consolidated balance sheets and in income 
tax expense in our consolidated statements of income.

Discrete  events  such  as  audit  settlements  or  changes  in  tax  laws  are 
recognized in the period in which they occur. Valuation allowances are 
established  when  management  is  unable  to  conclude  that  it  is  more 
likely  than  not  that  some  portion,  or  all,  of  the  deferred  tax  asset  will 
ultimately be realized.

The  Company  is  subject  to  income  taxes  in  the  United  States  and  in 
numerous foreign jurisdictions. With minor exceptions, no provision is 
made  for  U.S.  income  taxes  on  the  undistributed  earnings  of  wholly-
owned  foreign  subsidiaries  because  substantially  all  such  earnings 
are  indefinitely  reinvested  in  those  companies.  Provision  for  the 
tax  consequences  of  distributions,  if  any,  from  consolidated  foreign 
subsidiaries is recorded in the year in which the earnings are no longer 
indefinitely reinvested in those subsidiaries.

Equity Method Investments
Our  equity  method  investments  are  reviewed  for  impairment  on  a 
periodic  basis  or  if  an  event  occurs  or  circumstances  change  that 
indicate  the  carrying  amount  may  be  impaired.  This  assessment  is 
based on a review of the equity investments’ performance and a review 
of indicators of impairment to determine if there is evidence of a loss in 
value of an equity investment. Factors we consider include:

• Absence of our ability to recover the carrying amount;

• Inability of the equity affiliate to sustain an earnings capacity which 

would justify the carrying amount of the investment; and

• Significant  litigation,  bankruptcy  or  other  events  that  could  impact 

recoverability.

For  an  equity  investment  with  impairment  indicators,  we  measure 
fair  value  on  the  basis  of  discounted  cash  flows  or  other  appropriate 
valuation methods, depending on the nature of the company involved. 
If  it  is  probable  that  we  will  not  recover  the  carrying  amount  of  our 
investment,  the  impairment  is  considered  other-than-temporary  and 
recorded in earnings, and the equity investment balance is reduced to its 
fair value accordingly. We require our material equity method affiliates 
to provide audited financial statements. Consequently, adjustments for 
asset recoverability are included in equity earnings. We also utilize these 
financial statements in our recoverability assessment.

Fair Value of Financial Instruments
Major categories of financial assets and liabilities, including short-term 
investments, other assets and derivatives are measured at fair value on a 
recurring basis. Certain assets and liabilities including long-lived assets, 
goodwill, asset retirement obligations, and cost and equity investments 
are measured at fair value on a nonrecurring basis.

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. When determining the fair value 
measurements for assets and liabilities required  to be recorded at fair 
value, we consider the principal or most advantageous market in which 
we would transact and consider assumptions that market participants 
would  use  when  pricing  the  asset  or  liability,  such  as  inherent  risk, 
transfer restrictions, and risk of nonperformance.

Derivative Instruments
We  participate  in  a  variety  of  foreign  exchange  forward  contracts  and 
foreign  exchange  option  contracts  entered  into  in  connection  with 
the  management  of  our  exposure  to  fluctuations  in  foreign  exchange 
rates. We utilize interest rate swaps  to reduce  the risk of changes in a 
benchmark interest rate from the probable forecasted issuance of debt 
and  to  swap  fixed  rate  interest  payments  into  floating  rate  interest 
payments. These  financial  exposures  are  managed  in  accordance  with 
corporate policies and procedures.

All derivatives are recorded at fair value on the balance sheet. Changes in 
the fair value of derivatives designated as cash flow hedges and hedges 
of net investments in foreign operations are not recognized in current 
operating results but are recorded in accumulated other comprehensive 
income.  Amounts  related  to  cash  flow  hedges  are  reclassified  from 
accumulated  other  comprehensive 
income  when  the  underlying 
hedged  item  impacts  earnings. This  reclassification  is  recorded  in  the 
same line item of the consolidated statements of income as where the 
effects of the hedged item are recorded, typically sales, cost of sales or 
other (expense) income, net. Changes in the fair value of derivatives not 
designated  as  hedging  instruments  are  recorded  in  the  Consolidated 
Statements of Income in the Translated earnings contract (loss) gain, net 
and the Other (expense) income, net lines.

New Accounting Standards
In May 2014, the Financial Accounting Standards Board (“FASB”) issued 
Accounting  Standards  Update  (“ASU”)  No.  2014-09,  Revenue  from 
Contracts  with  Customers,  as  a  new  Topic,  Accounting  Standards 
Codification  (“ASC”) Topic  606. The  new  revenue  recognition  standard 
relates  to  revenue  from  contracts  with  customers,  which,  along  with 
amendments issued in 2015 and 2016, will supersede nearly all current 
U.S.  GAAP  guidance  on  this  topic  and  eliminate  industry-specific 
guidance.  The  underlying  principle  is  to  use  a  five-step  analysis  of 
transactions to recognize revenue when promised goods or services are 
transferred  to customers in an amount  that reflects  the consideration 
that is expected to be received for those goods or services. Corning has 
evaluated its material contracts, and has concluded that the impact of 
adopting the standard on its financial statements and related disclosure 
will  not  be  material.  The  standard,  as  amended,  will  be  effective  for 
annual  periods  beginning  after  December  15,  2017,  including  interim 
periods within that reporting period. We expect to adopt the standard 
on a modified retrospective basis in 2018.

Corning’s  equity  affiliates  are  currently  evaluating  their  material 
contracts, and have not concluded on the potential impact of adopting 
ASU 2014-09 on their financial statements and related disclosure.

In  February  2016,  the  FASB  issued  ASU  2016-02,  Leases  (Topic  842), 
which supersedes all existing guidance on accounting for leases in ASC 
Topic  840.  ASU  2016-02  is  intended  to  provide  enhanced  transparency 
and  comparability  by  requiring  lessees  to  record  right-of-use  assets 
and  corresponding  lease  liabilities  on  the  balance  sheet.  ASU  2016-
02  will  continue  to  classify  leases  as  either  finance  or  operating,  with 
classification  affecting  the  pattern  of  expense  recognition  in  the 
statement of income. ASU 2016-02 is effective for fiscal years beginning 
after  December  15,  2018,  including  interim  periods  within  those  fiscal 
years. Early adoption is permitted. ASU 2016-02 is required to be applied 
with  a  modified  retrospective  approach  to  each  prior  reporting  period 
presented  with  various  optional  practical  expedients. We  are  currently 
assessing the potential impact of adopting ASU 2016-02 on our financial 
statements and related disclosures.

In  March  2016,  the  FASB  issued  ASU  2016-09,  Compensation—Stock 
Compensation  (Topic  718):  Improvements  to  Employee  Share-Based 
Payment  Accounting.  ASU  2016-09  changes  how  companies  account 
for  certain  aspects  of  share-based  payment  awards  to  employees, 
including  the  accounting  for  income  taxes,  forfeitures  and  statutory 
tax withholding requirements, as well as classification in the statement 
of  cash  flows.  ASU  2016-09  is  effective  for  annual  periods  beginning 
after December 15, 2016, including interim periods within those annual 
periods. If an entity early adopts in an interim period, any adjustments 
should be reflected as of the beginning of the fiscal year that includes 
that interim period and  the entity must adopt all of  the amendments 
from  ASU  2016-09  in  the  same  period. We  have  determined  that  the 
impact of this standard will not be material. We will adopt this standard 
in 2017.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows 
(Topic 230): Classification of Certain Cash Receipts and Cash Payments. 
ASU  2016-15  refines  how  companies  classify  certain  aspects  of  the 
cash  flow  statement  in  regards  to  debt  prepayment,  settlement  of 
debt  instruments,  contingent  consideration  payments,  proceeds  from 
insurance  claims  and  life  insurance  policies,  distribution  from  equity 
method investees, beneficial interests in securitization transactions and 
separately  identifiable  cash  flows.  ASU  2016-15  is  effective  for  annual 
periods  beginning  after  December  15,  2017,  and  for  interim  periods 
within fiscal years beginning after December 15, 2018. No early adoption 
is permitted. We are currently assessing the potential impact of adopting 
ASU 2016-15 on our financial statements and related disclosures.

In October 2016,  the FASB issued ASU No. 2016-16, Income Taxes (Topic 
740): Intra-Entity Transfers of Assets Other Than Inventory, which reduces 
the complexity in the accounting standards by allowing the recognition 
of current and deferred income taxes for an intra-entity asset transfer, 
other than inventory, when the transfer occurs. Historically, recognition 
of  the  income  tax  consequence  was  not  recognized  until  the  asset 
was sold  to an outside party. This amendment should be applied on a 
modified  retrospective  basis  through  a  cumulative-effect  adjustment 
directly  to  retained  earnings  as  of  the  beginning  of  the  period  of 
adoption.  ASU  2016-16  is  effective  for  annual  periods  beginning  after 
December  15,  2017,  including  interim  reporting  periods  within  those 
annual  reporting  periods.  Early  adoption  is  permitted  for  all  entities 
as  of  the  beginning  of  an  annual  reporting  period  for  which  financial 
statements (interim or annual) have not been issued or made available 
for  issuance.  That  is,  earlier  adoption  should  be  in  the  first  interim 
period if an entity issues interim financial statements. We are currently 
evaluating  the  impact  of  ASU  2016-16  on  our  consolidated  financial 
statements and related disclosures.

In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and 
Other (Topic 350). ASU 2017-04 simplifies the subsequent measurement 
of  goodwill  by  removing  the  second  step  of  the  two-step  impairment 
test. The amendment requires an entity to perform its annual, or interim 
goodwill impairment test by comparing the fair value of a reporting unit 
with its carrying amount. An impairment charge should be recognized 
for  the  amount  by  which  the  carrying  amount  exceeds  the  reporting 
unit’s  fair  value;  however,  the  loss  recognized  should  not  exceed  the 
total amount of goodwill allocated to that reporting unit. An entity still 
has  the  option  to  perform  the  qualitative  assessment  for  a  reporting 
unit to determine if the quantitative impairment test is necessary. The 
amendment  should  be  applied  on  a  prospective  basis.  ASU  2017-04  is 
effective  for  fiscal  years  beginning  after  December  15,  2019,  including 
interim  periods  within  those  fiscal  years.  Early  adoption  is  permitted 
for interim or annual goodwill impairment tests performed on testing 
dates after January 1, 2017. The Company intends to early adopt the ASU 
in 2017.

2.  Restructuring, Impairment and Other Charges

2016 Activity
For  the  year  ended  December  31,  2016,  we  recorded  charges  of  $77 
million, pre-tax, for employee related costs of $14 million, asset disposals 
of $62 million, and exit costs associated with some minor restructuring 
activities in all of our segments of $1 million, with total cash expenditures 
of approximately $12 million.

Cash  payments  for  employee-related  and  exit  activity  related  to  the 
2016  restructuring  activities  were  substantially  completed  in  2016. 
Restructuring  reserves  as  of  December  31,  2016,  2015  and  2014  were 
not significant.

2015 Activity
For  the  year  ended  December  31,  2015,  we  did  not  record  significant 
restructuring, 
impairment  and  other  charges  or  reversals.  Cash 
expenditures for restructuring activities were $40 million.

2014 Activity
For the year ended December 31, 2014, we recorded charges of $71 million 
for workforce reductions of $48 million, asset disposals and write-offs of 
$22 million, and exit costs for restructuring activities of $1 million with 
total cash expenditures of approximately $39 million.

Cash payments for employee-related and exit activity related to the 2014 
restructuring actions were substantially completed in 2015.

3.  Available-for-Sale Investments

At  December  31,  2015,  the  Company  held  $100  million  of  short-term 
investments  (U.S.  government  and  agency  securities).  At  December  31, 
2016 and 2015, the Company held long-term investments of $29 million 
and $33 million in asset-backed securities, respectively. The Company’s 
investments  in  available-for-sale  securities  are  held  at  fair  value  with 
amortized cost of $32 million and $37 million at December 31, 2016 and 
2015, respectively.

4.  Significant Customers

We have no plans to sell, nor do we believe it is more likely than not that 
we  would  be  required  to  sell,  the  long-term  investment  asset-backed 
securities  (which  are  collateralized  by  mortgages)  before  recovery  of 
their amortized cost basis. It is possible that a significant degradation in 
the delinquency or foreclosure rates in the underlying assets could cause 
further temporary or other-than-temporary impairments in the future.

Proceeds from sales and maturities of short-term investments  totaled 
$121 million, $1.6 billion and $1.2 billion in 2016, 2015 and 2014, respectively.

For 2016 and 2015, Corning’s sales to Samsung Display Co. Ltd., a customer of our Display Technologies and Specialty Materials segments, represented 
11% of the Company’s consolidated net sales. For 2014, Corning’s sales to Samsung Display Co. Ltd., a customer of our Display Technologies segment, 
represented 14% of the Company’s consolidated net sales.

Currently,  the  recognition  of  windfall  tax  benefits  from  stock-based 
compensation  deducted  on  the  tax  return  is  prohibited  until  realized 
through a reduction of income tax payable. In 2017, we will adopt ASU 
2016-09, Improvements to Employee Share-Based Payment Accounting. 
At  that  time,  the cumulative  tax benefits  totaling $233 million will be 
recorded in beginning retained earnings.

Deferred tax assets are to be reduced by a valuation allowance if, based 
on  the  weight  of  available  positive  and  negative  evidence,  it  is  more 
likely  than  not  (a  likelihood  of  greater  than  50  percent)  that  some 
portion or all of the deferred tax assets will not be realized. Corning has 
valuation  allowances  on  certain  shorter-lived  deferred  tax  assets  such 
as  those  represented  by  capital  loss  and  state  tax  net  operating  loss 

carryforwards, as well as other foreign net operating loss carryforwards, 
because we cannot conclude that it is more likely than not that we will 
earn  income  of  the  character  required  to  utilize  these  assets  before 
they  expire.  U.S.  profits  of  approximately  $5.6  billion  will  be  required 
to fully realize  the U.S. deferred  tax assets as of December 31,  2016, of 
which $116 million will be required over the next 20 years to realize the 
deferred tax assets related to general business credits and $2.8 billion of 
foreign sourced income will be required over the next 10 years to fully 
realize  the deferred  tax assets associated with foreign  tax credits. The 
amount  of  U.S.  and  foreign  deferred  tax  assets  that  have  remaining 
valuation  allowances  at  December  31,  2016  and  2015  was  $270  million 
and $238 million, respectively.

57

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

The following is a tabular reconciliation of the total amount of unrecognized tax benefits (in millions):

Balance at January 1

Additions based on tax positions related to the current year

Additions for tax positions of prior years

Reductions for tax positions of prior years

Settlements and lapse of statute of limitations

Balance at December 31

The 2015 additions for tax positions of prior years include $221 million for 
unrecognized tax benefits related to gross transfer pricing adjustments, 
of which $31 million tax expense is related to out of period adjustments. 
The impact of these corrections is not material to any individual period 
previously  presented.  Since  the  Company  operates  in  a  number  of 
countries with income  tax  treaties, an offsetting benefit was recorded 
where  it  believes  it  is  more-likely-than-not  to  receive  competent 
authority relief. Included in the balance at December 31, 2016 and 2015 
are  $92  million  and  $102  million,  respectively,  of  unrecognized  tax 
benefits that would impact our effective tax rate if recognized.

We recognize accrued interest and penalties associated with uncertain 
tax positions as part of tax expense. For the years ended December 31, 
2016 and 2015 the amount recognized in interest expense is not material. 
The amounts accrued at December 31, 2016 and 2015 for the payment of 
interest and penalties were also not material.

We do not expect a material change to the amount of unrecognized tax 
benefits in the next 12 months.

Corning Incorporated, as the common parent company, and all 80%-or-
more-owned of its U.S. subsidiaries join in the filing of consolidated U.S. 
federal  income  tax  returns.  The  statute  of  limitations  is  closed  for  all 
periods ending through December 31, 2012. All returns for periods ended 
through December 31, 2004, have been audited by and settled with the 
Internal Revenue Service (IRS).

Corning  Incorporated  and  its  U.S.  subsidiaries  file  income  tax  returns 
on a combined, unitary or stand-alone basis in multiple state and local 
jurisdictions, which generally have statutes of limitations ranging from 
3 to 5 years. Various state income tax returns are currently in the process 
of examination or administrative appeal.

Our  foreign  subsidiaries  file  income  tax  returns  in  the  countries  in 
which they have operations. Generally, these countries have statutes of 
limitations ranging from 3 to 7 years. Years still open to examination by 
foreign tax authorities in major jurisdictions include Japan (2009, 2015 
onward), Taiwan (2015 onward) and South Korea (2015 onward).

Corning continues to indefinitely reinvest substantially all of its foreign 
earnings,  with  the  exception  of  an  immaterial  amount  of  current 
earnings  that  have  very  low  or  no  tax  cost  associated  with  their 
repatriation. Our current analysis indicates that we have sufficient U.S. 
liquidity,  including  borrowing  capacity,  to  fund  foreseeable  U.S.  cash 
needs  without  requiring  the  repatriation  of  foreign  cash.  One  time 
or  unusual  items  may  impact  our  ability  or  intent  to  keep  our  foreign 
earnings and cash indefinitely reinvested. As of December 31, 2016, taxes 
have not been provided on approximately $12.6 billion of accumulated 
foreign  unremitted  earnings  that  are  expected  to  remain  invested 
indefinitely. While it remains impracticable to calculate the tax cost of 
repatriating  our  total  unremitted  foreign  earnings,  such  cost  could  be 
material to the results of operations of Corning in a particular period.

of  December  31,  2016  the  undistributed  earnings  of  equity  companies 
included in our retained earnings are not material.

Samsung Corning Precision Materials

Prior  to  December  2013,  Corning  owned  50%  of  its  equity  affiliate, 
Samsung  Corning  Precision  Materials,  Samsung  Display  owned  42.5% 
and three shareholders owned the remaining 7%. In the fourth quarter 
of 2013, in connection with a series of strategic and financial agreements 
with Samsung Display announced in October 2013, Corning acquired the 
minority interests of three shareholders in Samsung Corning Precision 
Materials for $506 million, which included payment for the transfer of 
non-operating assets and the pro-rata portion of cash on the Samsung 
Corning  Precision  Materials  balance  sheet  at  September  30,  2013. The 
resulting  transfer  of  shares  to  Corning  increased  Corning’s  ownership 
percentage of Samsung Corning Precision Materials from 50% to 57.5%. 
Because this transaction did not result in a change in control based on 
the governing documents of this entity, Corning did not consolidate this 
entity as of December 31, 2013.

As further discussed in Note 8 (Acquisitions), on January 15, 2014, Corning 
completed the acquisition of the common shares of Samsung Corning 
Precision  Materials  previously  held  by  Samsung  Display.  As  a  result  of 
these transactions, Corning became the owner of 100% of the common 
shares of Samsung Corning Precision Materials, which were consolidated 
into our results beginning in the first quarter of 2014. Operating under 
the name of Corning Precision Materials, the former Samsung Corning 
Precision  Materials  organization  and  operations  were  integrated  into 
the Display Technologies segment in the first quarter of 2014.

Dow Corning

On  May  31,  2016,  Corning  completed  the  strategic  realignment  of 
its  equity  investment  in  Dow  Corning  Corporation  (”Dow  Corning”) 
pursuant  to  the Transaction Agreement announced in December 2015. 
Under the terms of the Transaction Agreement, Corning exchanged with 
Dow Corning its 50% stock interest in Dow Corning for 100% of the stock 
of  a  newly  formed  entity,  which  holds  an  equity  interest  in  Hemlock 
Semiconductor Group (“HSG”) and approximately $4.8 billion in cash.

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

Prior  to  realignment,  HSG,  a  consolidated  subsidiary  of  Dow  Corning, 
was an indirect equity investment of Corning. Upon completion of the 
exchange, Corning now has a direct equity investment in HSG. Because 
our  ownership  percentage  in  HSG  did  not  change  as  a  result  of  the 
realignment,  the  investment  in  HSG  is  recorded  at  its  carrying  value, 
which had a negative carrying value of $383 million at the transaction 
date. The  negative  carrying  value  resulted  from  a  one-time  charge  to

Pittsburgh Corning Corporation and Asbestos Litigation.

Corning  and  PPG  Industries,  Inc.  each  owned  50%  of  the  capital  stock 
of  Pittsburgh  Corning  Corporation  (“PCC”).  PCC  filed  for  Chapter  11 
reorganization  in  2000  and  the  Modified  Third  Amended  Plan  of 
Reorganization  for  PCC  (the “Plan”)  became  effective  in  April  2016.  At 
December 31, 2015, the Company’s liability under the Plan was estimated 
to  be  $528  million.  At  December  31,  2016,  this  estimated  liability  was 
$290 million, due to the Company’s contribution, in the second quarter 
of 2016, of its equity interests in PCC and Pittsburgh Corning Europe N.V. 
in  the  total  amount  of  $238  million,  as  required  by  the  Plan.  Corning 
recognized  a  gain  of  $56  million  in  the  second  quarter  of  2016  in  the 

selling,  general  and  administrative  expenses  line  of  the  Company’s 
Consolidated  Statements  of  Income  for  the  difference  between  the 
fair  value  of  the  asbestos  litigation  liability  and  carrying  value  of  the 
investment. This gain includes the release of foreign translation losses 
in  the  amount  of  $25  million  reclassified  from  accumulated  other 
comprehensive  income. The  remaining  $290  million  liability  is  for  the 
series  of  fixed  payments  required  by  the  Plan.  At  December  31,  2016, 
the  total  amount  of  the  payments  due  in  years  2018  through  2022  is 
$220  million  and  is  classified  as  a  non-current  liability. The  remaining 
$70 million payment due in  the second quarter of 2017 is classified as 
a  current  liability  because  it  is  expected  to  be  made  within  the  next 
twelve months.

CORNING INCORPORATED - 2016 Annual ReportNon-PCC Asbestos Claims Insurance Litigation

Corning is a defendant in certain cases alleging injuries from asbestos 
unrelated to PCC (the “non-PCC asbestos claims”) which had been stayed 
pending the confirmation of the Plan. The stay was lifted on August 25, 
2016. Corning previously established a $150 million reserve for these non-
PCC asbestos claims. The estimated reserve represents the undiscounted 
projection of claims and related legal fees. The amount may need to be 
adjusted in future periods as more data becomes available; however, we 
cannot estimate any lesser or greater liabilities at this time.

Notes to Consolidated Financial Statements

Several of Corning’s insurers have commenced litigation in state courts 
for  a  declaration  of  the  rights  and  obligations  of  the  parties  under 
insurance policies, including rights that may be affected by the potential 
resolutions  described  above.  Corning  has  resolved  these  issues  with  a 
majority of its relevant insurers, and is vigorously contesting these cases 
with the remaining relevant insurers. Management is unable to predict 
the outcome of the litigation with these remaining insurers.

Year ended December 31, 2016

There were no material acquisitions completed in 2016. See Note 10 (Goodwill and Other Intangible Assets) for further information on goodwill and 
intangibles acquired in 2016.

Year ended December 31, 2015

Corning  completed  five  acquisitions  in  2015. There  were  minor  adjustments  during  2015  made  to  the  preliminary  allocation  of  the  total  purchase 
consideration related to working capital adjustments and true-up of the fair value of assets acquired for the acquisitions. Corning has completed the

(1)  The goodwill recognized is partially deductible for U.S. income tax purposes. The goodwill was allocated to the Optical Communications and All 

Other reporting segment in the amount of $213 million and $87 million, respectively.

The goodwill generated from  these acquisitions is primarily related  to 
the value of the product portfolio and customer/distribution networks 
acquired,  combined  with  Corning’s  existing  business  segments,  as 
well as market participant synergies and other intangibles that do not 
qualify for separate recognition.

The  acquired  amortizable  intangible  assets  have  a  weighted-average 
useful life of approximately 10 years.

Acquisition-related costs of $11 million included in selling, general and 
administrative  expense  in  the  Consolidated  Statements  of  Income  for 
the year ended December 31, 2015 included costs for legal, accounting, 
valuation  and  other  professional  services.  The  Consolidated  Financial 
Statements include the operating results of each business combination 
from  the date of acquisition. Pro forma results of operations have not 
been presented because the effects of the acquisitions, individually and 
in the aggregate, were not material to Corning’s financial results.

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

Year ended December 31, 2014

On  January  15,  2014,  Corning  completed  a  series  of  strategic  and 
financial  agreements  pursuant  to  the  Framework  Agreement  with 
Samsung Display to acquire the remaining common shares of Samsung 
Corning Precision Materials. The transaction is expected to strengthen 
product  and  technology  collaborations  between  the  two  companies 
and allow Corning to extend its leadership in specialty glass and drive 
earnings growth.

The acquisition of Samsung Corning Precision Materials was accounted 
for  under  the  purchase  method  of  accounting  in  accordance  with 
business  combination  accounting  guidance.  Accordingly,  the  purchase 
price  was  allocated  to  the  assets  acquired  and  liabilities  assumed, 
based on their fair value on the date of acquisition. The fair value was 
determined based on the fair value of consideration transferred for the 
remaining equity interest of Samsung Display’s shares.

In  connection  with  the  purchase  of  Samsung  Display’s  equity  interest 
in  Samsung  Corning  Precision  Materials  pursuant  to  the  Framework 
Agreement,  the  Company  designated  a  new  series  of  its  preferred 
stock  as  Fixed  Rate  Cumulative  Convertible  Preferred  Stock,  Series  A, 
par  value  $100  per  share  (“Preferred  Stock”).  As  contemplated  by  the 
Framework  Agreement,  Samsung  Display  became  the  owner  of  2,300 
shares of Preferred Stock (with an issue price of $1 million per share), of 
which 1,900 shares were issued in connection with the acquisition and 
400 shares were issued for cash.

Corning  issued  1,900  shares  of  Preferred  Stock  as  consideration  in 
the  acquisition  of  Samsung  Corning  Precision  Materials  which  had 
a  fair  value  of  $1.9  billion  on  the  acquisition  date.  The  fair  value  was 
determined using an option pricing model based on the features of the 
Preferred Stock. That measure is based on Level 2 inputs observable in 
the market such as Corning’s common stock price and dividend yield.

As  a  result  of  the  acquisition  of  Samsung  Corning  Precision  Materials 
in  January  2014,  the  Company  has  contingent  consideration  that 
was  measured  using  unobservable  (Level  3)  inputs.  This  contingent 
consideration arrangement potentially requires additional consideration 
to be paid between the parties in 2018: one based on projections of future 

revenues generated by  the business of Corning Precision Materials for 
the period between the acquisition date and December 31, 2017, which 
is subject to a cap of $665 million; and another based on the volumes of 
certain sales during the same period, which is subject to a separate cap 
of $100 million. The fair value of the potential receipt of the contingent 
consideration in 2018 in the amount of $196 million recognized on the 
acquisition  date  was  estimated  by  applying  an  option  pricing  model 
using  the  Company’s  projection  of  future  revenues  generated  by 
Corning Precision Materials. Changes in the fair value of the contingent 
consideration in future periods are valued using an option pricing model 
and are recorded in Corning’s results in the period of the change.

On  December  29,  2015,  Corning  and  Samsung  Display  entered  into 
an  agreement  pursuant  to  which  Corning  exchanged  the  amount  of 
contingent  consideration  in  excess  of  $300  million  (net  present  fair 
value:  $246  million),  as  consideration  for  the  incremental  fair  value 
associated  with  a  number  of  commercial  agreements,  including  the 
amendment of its long-term supply agreement with Samsung Display. 
As  of  December  29,  2015,  the  net  present  fair  value  of  the  contingent 
consideration receivable was $458 million. The net present fair value of 
the commercial benefit associated with the amended long-term supply 
agreement  exceeds  the  value  exchanged  by  Corning  pursuant  to  this 
agreement (net present fair value: $212 million). Consequently, Corning 
reclassified  this  amount  to  the  other  asset  line  of  the  Consolidated 
Balance Sheet and will amortize the amount over the remaining term of 
the long-term supply agreement as a reduction in revenue.

As  of  December  31,  2016  and  December  31,  2015,  the  fair  value  of 
the  potential  receipt  of  the  contingent  consideration  in  2018  was 
$289 million and $246 million, respectively.

The  following  table  summarizes  the  total  fair  value  of  Samsung 
Corning  Precision  Materials  at  the  acquisition  date  including  the  net 
consideration  transferred  to  acquire  the  remaining  42.5%  of  Samsung 
Corning Precision Materials, the fair value of Corning’s non-controlling 
interest  in  Samsung  Corning  Precision  Materials  pre-  and  post-
acquisition and the amount of the implied fair value of the total entity 
for  the  purpose  of  allocating  the  purchase  price  to  the  acquired  net 
assets.

The $1.9 billion fair value of consideration transferred for the remaining 
42.5% interest in Samsung Corning Precision Materials plus the fair value 
of Corning’s pre-acquisition fair value less the contingent consideration 
due Corning as of the acquisition date results in a net fair value for the 
total entity of $4 billion.

As a result of  the acquisition of  Samsung Corning  Precision Materials, 
Corning reacquired its technology license rights and effectively settled 
its  pre-existing  royalty  contract  with  the  acquired  entity,  Samsung 
Corning Precision Materials. With regard to the reacquired right, Corning 
engaged  a  third-party  specialist  to  assist  in  assessing  the  fair  value 
of  this  right  and  determined  that  the  reacquired  right  had  a  value  of 
zero.  In  addition,  the  Company  assessed  whether  this  royalty  contract 

was  favorable  or  unfavorable  to  Corning.  It  was  determined  that  the 
contractual royalty rate of 3% as compared to the then current market 
rate  of  12%  was  unfavorable  to  Corning.  The  effective  settlement  of 
the  contract  was  valued  using  the  Income  Approach;  specifically,  a 
relief  from  royalty  method.  The  amount  by  which  the  contract  was 
unfavorable to Corning when compared to current market transactions 
for similar items resulted in a loss of $320 million which was recorded 
on the acquisition date, representing 100% of the loss on the effective 
settlement of the contract. There were no stated contractual settlement 
provisions  or  previously  recorded  assets  or  liabilities  to  consider  when 
determining the value associated with the settlement.

62

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

Because the pre-existing contract was unfavorable to Corning, a portion 
of  the  consideration  transferred  was  deemed  to  be  applicable  to  the 
effective  settlement  of  the  royalty  contract  between  Corning  and  the 
acquiree,  Samsung  Corning  Precision  Materials.  The  $320  million  loss 
attributable  to  the  settlement  of  the  pre-existing  arrangement  was 
accounted for as a separate transaction from the business combination 
as follows:

• At  acquisition,  since  the  contract  with  Samsung  Corning  Precision 
Materials  was  effectively  settled,  Corning  recognized  a  loss  of 
$320  million.  Of  the  $320  million,  $184  million  effectively  offset  the 
portion of the gain on previously held equity investment attributable 
to  Corning’s  interest  in  the  royalty  contract.  As  a  result,  the  pre-
acquisition fair value of Corning’s 57.5% share of $2.3 billion decreased 
to the fair value of $2.1 billion post-acquisition; and

• At  acquisition,  since  the  seller,  Samsung  Display,  was  a  42.5% 
shareholder  of  Samsung  Corning  Precision  Materials,  42.5%,  or 

The net gain on previously owned equity was calculated as follows:

$136 million, of the $320 million loss to effectively settle the contract 
reduced  the  consideration  transferred  to  acquire  Samsung  Display’s 
interest 
in  Samsung  Corning  Precision  Materials.  Accordingly, 
$136  million  of  the  consideration  transferred  was  treated  separately 
from  the  purchase  price,  resulting  in  the  implied  consideration 
transferred of approximately $1.6 billion.

The net economic effect to Corning following the transaction was a net 
loss  of  $136  million,  constituting  a  $320  million  loss  due  to  Corning’s 
unfavorable contract and its share of the favorable contract in Samsung 
Corning Precision Materials of $184 million.

The gain on the previously held equity investment was calculated based 
on the fair value of the entity immediately preceding the acquisition of 
Samsung Corning Precision Materials. As the pre-existing contract was 
treated  as  a  separate  transaction,  the  pre-existing  contract  was  not 
taken  into  consideration  when  calculating  the  gain  on  the  previously 
held equity interest.

(1)  In  conjunction  with  the  Framework  Agreement,  the  parties  agreed  to  have  Samsung  Corning  Precision  Materials  distribute  all  cash  and  cash 
equivalents as a dividend to the shareholders of record as of December 31, 2013. The dividend was not part of the purchase price as the agreement 
was  to  distribute  cash  and  cash  equivalents  as  a  dividend  to  the  shareholders  as  soon  as  practicable.  As  such,  at  acquisition  Corning  did  not 
have legal title to the cash to be distributed, although the dividend was distributed subsequent to the acquisition date. Therefore, the portion of 
Corning’s share of the $1.6 billion dividend received was accounted for in Corning’s consolidated financial statements as if the dividend occurred 
at or immediately prior to the date of acquisition at which time Samsung Corning Precision Materials was still an equity method investment in 
Corning’s consolidated financial statements.

(2) As Corning was a 57.5% shareholder at  the date of acquisition, immediately preceding  the acquisition of Samsung Corning Precision Materials, 
Corning recognized an asset and respective gain as part of the calculation of its previously held equity investment which included approximately 
$184 million attributed to its economic interest in the royalty contract.

(2) The goodwill recognized is not deductible for U.S. income tax purposes. The goodwill was allocated to the Display Technologies segment.

(3) During  2014,  the  Company  recorded  total  measurement  period  adjustments  of  $60  million  for  the  acquisition  of  Corning  Precision  Materials 

primarily related to accrual of contingent liabilities and employee benefit obligations.

The  goodwill 
is  primarily  attributable  to  the  workforce  of  the 
acquired  business  and  the  synergies  expected  to  result  from  the 
integration  of  Corning  Precision  Materials.  Acquisition-related  costs 
of  $93  million  in  the  year  ended  December  31,  2014  included  costs  for 
post-acquisition  compensation  expense,  legal,  accounting,  valuation 
and  other  professional  services  and  were  included  in  selling,  general 
and administrative expenses in the Consolidated Statements of Income. 

Since  the  date  of  acquisition,  the  consolidation  of  Corning  Precision 
Materials  added  $1,317  million,  $1,343  million  and  $1,761  million  to  net 
sales for the years ending December 31, 2016, 2015 and 2014, respectively. 
The  impact  to  net  income  of  the  consolidation  of  Corning  Precision 
Materials  is  impracticable  to  calculate  due  to  the  level  of  integration 
within the Display Technologies segment and the significant amount of 
estimates that would be required.

(1)  The negative carrying value resulted from a one-time charge to this entity in 2014 for the permanent abandonment of certain assets. Refer to Note 

7 (Investments) to the Consolidated Financial Statements for additional information.

Asbestos Litigation
Corning and PPG each owned 50% of the capital stock of PCC. Over a period of more than two decades, PCC and several other defendants were named 
in numerous lawsuits involving claims alleging personal injury from exposure to asbestos. Refer to Note 7 (Investments) to the Consolidated Financial 
Statements for additional information on the asbestos litigation.

Customer Deposits
In  December  2015,  Corning  announced  that  with  the  support  of  the 
Hefei government it will locate a Gen 10.5 glass manufacturing facility 
in the Hefei XinZhan General Pilot Zone in Anhui Province, China. Glass 
substrate production from the new facility is expected to support mass 
production of LCD panels for large-size televisions beginning in 2018.

As part of this investment, Corning and a Chinese customer have entered 
into a long-term supply agreement that commits the customer to the 
purchase of Gen 10.5 glass substrates from the Corning manufacturing 
facility  in  Hefei.  This  agreement  stipulates  that  the  customer  will 

provide a non-refundable cash deposit in the amount of approximately 
$400 million to Corning to secure rights to an amount of glass that is 
produced by Corning over  the next 10 years. Corning has collected  the 
full amount of this deposit, adjusted for foreign exchange movements, 
receiving  $185  million  of  this  deposit  in  2016  and  $197  million  in  2015. 
As  glass  is  shipped  to  the  customer,  Corning  will  recognize  revenue 
and  issue  credit  memoranda  to  reduce  the  amount  of  the  customer 
deposit  liability,  which  are  applied  against  customer  receivables 
resulting from the sale of glass. In 2016 and 2015, there were no credit 
memoranda issued.

At  December  31,  2016  and  2015,  the  weighted-average  interest  rate  on 
current  portion  of  long-term  debt  was  1.5%  and  7.0%,  respectively.  At 
December  31,  2015,  the  weighted-average  interest  rate  on  commercial 
paper was 0.6%. Corning did not have outstanding commercial paper at 
December 31, 2016.

Based on borrowing rates currently available to us for loans with similar 
terms and maturities, the fair value of long-term debt was $3.9 billion at 
December 31, 2016 and $4.1 billion at December 31, 2015. The Company 
measures the fair value of its long-term debt using Level 2 inputs based 
primarily  on  current  market  yields  for  its  existing  debt  traded  in  the 
secondary market.

• In  the  third  quarter  of  2016,  Corning’s  Board  of  Directors  approved 
a  $1  billion  increase  to  our  commercial  paper  program,  raising  it 
to  $2  billion.  If  needed,  this  program  is  supported  by  our  $2  billion 
revolving credit facility that expires in 2019.

• In  the second quarter of 2015, we issued $375 million of 1.50% senior 
unsecured notes that mature on May 8, 2018 and $375 million of 2.90% 
senior unsecured notes that mature on May 15, 2022. The net proceeds 
of  $745  million  will  be  used  for  general  corporate  purposes. We  can 
redeem  these notes at any  time, subject  to certain customary  terms 
and conditions.

13.  Employee Retirement Plans

Defined Benefit Plans
We have defined benefit pension plans covering certain domestic and 
international employees. Our funding policy has been to contribute, as 
necessary, an amount in excess of the minimum requirements in order 
to achieve the Company’s long-term funding targets. In 2016, we made 
voluntary  cash  contributions  of  $73  million  to  our  domestic  defined 
benefit  pension  plan  and  $16  million  to  our  international  pension 
plans.  In  2015,  we  made  voluntary  cash  contributions  of  $65  million 
to  our  domestic  defined  benefit  pension  plan  and  $35  million  to  our 
international  pension  plans.  We  are  not  subject  to  any  mandatory 
contributions  in  2017,  and  do  not  anticipate  making  voluntary  cash 
contributions  to  our  U.S.  qualified  pension  plan.  We  anticipate 
contributing up to $23 million to our international pension plans in 2017.

Corning  offers  postretirement  plans  that  provide  health  care  and 
life  insurance  benefits  for  retirees  and  eligible  dependents.  Certain 
employees may become eligible for such postretirement benefits upon 

reaching retirement age and service requirements. For current retirees 
(including  surviving  spouses)  and  active  employees  eligible  for  the 
salaried retiree medical program, we have placed a “cap” on the amount 
we  will  contribute  toward  retiree  medical  coverage  in  the  future. The 
cap is equal  to 120% of our 2005 contributions  toward retiree medical 
benefits.  Once  our  contributions  toward  salaried  retiree  medical  costs 
reach this cap, impacted retirees will have to pay the excess amount in 
addition to their regular contributions for coverage. This cap was attained 
for post-65 retirees in 2008 and has impacted their contribution rate in 
2009 and going forward. The pre-65 retirees triggered the cap in 2010, 
which has impacted their contribution rate in 2011 and going forward. 
Furthermore,  employees  hired  or  rehired  on  or  after  January  1,  2007 
will  be  eligible  for  Corning  retiree  medical  benefits  upon  retirement; 
however, these employees will pay 100% of the cost.

The Company expects to recognize $6 million of net prior service cost as 
a component of net periodic pension cost in 2017 for its defined benefit 
pension  plans.  The  Company  expects  to  recognize  $1  million  of  net 
actuarial gain and $3 million of net prior service credit as components of 
net periodic postretirement benefit cost in 2017.

Corning uses a hypothetical yield curve and associated spot rate curve to 
discount the plan’s projected benefit payments. Once the present value 
of projected benefit payments is calculated, the suggested discount rate 
is equal to the level rate that results in the same present value. The yield 

curve  is  based  on  actual  high-quality  corporate  bonds  across  the  full 
maturity  spectrum,  which  also  includes  private  placements  as  well  as 
Eurobonds that are denominated in U.S. currency. The curve is developed 
from yields on approximately 350-375 bonds from four grading sources, 
Moody’s, S&P, Fitch and the Dominion Bond Rating Service. A bond will 
be included if at least half of the grades from these sources are Aa, non-
callable bonds. The very highest 10% yields and the lowest 40% yields are 
excluded from the curve to eliminate outliers in the bond population.

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

Mortality  is  one  of  the  key  assumptions  used  in  valuing  liabilities  of 
retirement plans. It is used to assign a probability of payment for future 
plan  benefits  that  are  contingent  upon  participants’  survival. To  make 
this  assumption,  benefit  plan  sponsors  typically  use  a  base  mortality 
table  and  an  improvement  scale  that  adjusts  the  rates  of  mortality 
for  future  anticipated  changes  to  historical  death  rates.  For  the  seven 
years  prior  to  the  year  ended  December  31,  2014,  Corning  utilized  the 
RP  2000  mortality  table  with  improvement  Scale  AA  in  performing 
valuations of its U.S. pension and OPEB liabilities. On October 27, 2014, 
the  Society  of  Actuaries  (“SOA”)  published  new  mortality  tables  for 
benefit  plan  sponsors  to  consider  when  measuring  their  benefit  plan 
costs and obligations. These tables reflect the fact that life expectancies 
have  improved  since  the  last  comprehensive  study  of  mortality  data 
was released in 2000. Therefore, in the fourth quarter of 2014, Corning 
undertook a review of its mortality assumption for its U.S. benefit plans 
to determine if an update to our current mortality table was appropriate. 
Based on the findings of this analysis, Corning believes that the RP-2014 
table  adjusted  for  Corning’s  experience  with  future  improvements 
projected  using  scale  BB-2D  represents  the  best  estimate  of  future 
mortality improvement for Corning’s U.S. benefit plans.

Prior to the December 31, 2015 valuation of its defined benefit pension 
and OPEB plans, Corning used the traditional, single weighted-average 
discount rate approach to develop the obligation, interest cost and service 
cost  components  of  net  periodic  benefit  cost  for  its  defined  benefit 
pension and OPEB plans. The individual spot rates from the yield curve 
are  used  in  measuring  the  pension  plan  projected  benefit  obligation 
(PBO)  or  OPEB  plan  accumulated  postretirement  benefit  obligation 
(APBO)  at  the  measurement  date. The  benefit  obligation  is  effectively 
calculated as the aggregate present value at the measurement date of 
each future benefit payment related to past service, with each payment 
discounted  using  a  spot  rate  from  a  high-quality  corporate  bond 
yield  curve  that  matches  the  duration  of  the  benefit  payment.  Under 
Corning’s traditional, single weighted-average discount rate approach, a 
single weighted-average rate is developed from the approach described 
above  and  rounded  to  the  nearest  25  basis  points.  Traditionally,  the 
weighted-average discount rate is determined at the plan measurement 
date,  based  on  the  same  projected  future  benefit  payments  used  in 
developing  the  benefit  obligation.  The  traditional  single  weighted-

average discount rate represents the constant annual rate that would be 
required to discount all future benefit payments related to past service 
from  the  date  of  expected  future  payment  to  the  measurement  date 
such that the aggregate present value equals the benefit obligation.

Beginning with  the December 31, 2015 valuation of its defined benefit 
pension  and  OPEB  plans,  Corning  changed 
its  methodology  of 
determining  the  service  and  interest  cost  components  of  net  periodic 
pension  and  other  postretirement  benefit  costs  to  a  more  granular 
approach. Under the new approach the cash flows from each applicable 
pension  and  OPEB  plan  will  be  used  to  directly  calculate  the  benefit 
obligation, service cost and interest cost using the spot rates from the 
applicable yield curve.

Moving  to  a  more  granular  approach  has  a  limited  impact  on  the 
determination of the respective benefit obligations. The only impacts will 
be as a result of the elimination of the rounding of the discount rate that 
occurred in the traditional approach and the use of specific cash flows 
for  Corning’s  non-qualified  pension  plans,  while  separately  applying 
the yield curve to each separate OPEB plan instead of aggregating the 
OPEB plan cash flows. This change will result in a decrease in the interest 
cost  and  service  cost  components  of  net  periodic  pension  and  OPEB 
costs.  For  the  year  ended  December  31,  2017,  net  periodic  pension  and 
OPEB  costs  will  be  lower  by  approximately  $23  million  and  $5  million, 
respectively, due to this change. For Corning’s pension plans, this change 
will increase the immediate recognition of actuarial losses (or decrease 
the immediate recognition of actuarial gains), due to Corning’s previous 
election  to  immediately  recognize  actuarial  gains  and  losses  outside 
of  the corridor. For Corning’s OPEB plans,  this change will increase  the 
accumulated other comprehensive income (AOCI) account balance due 
to the accumulation of lower actuarial gains or higher actuarial losses. 
Over time, the amortization of the actuarial losses from AOCI will begin 
to reduce the savings from the lower interest cost and service cost.

This  change  is  a  change  in  accounting  estimate  and  therefore 
applied  prospectively  (beginning  with  the  next  measurement  date  of 
December 31, 2015). No restatement of prior periods is required.

Measurement  of  postretirement  benefit  expense 
is  based  on 
assumptions used to value the postretirement benefit obligation at the 
beginning of the year.

Plan Assets

Corning’s expected long-term rates of return on plan assets reflect the 
average  rates  of  earnings  expected  on  the  funds  invested  to  provide 
for  the  benefits  included  in  our  domestic  and  international  projected 
benefit  obligations.    We  based  these  rates  on  asset/liability  forecast 
modeling, which is based on our current asset allocation, the return and 
standard deviation for each asset class, current market conditions and 
transitions from current conditions to long-term returns.  

The Company’s overall investment strategy is to obtain sufficient return 
to offset or exceed inflation and provide adequate liquidity to meet the 
benefit obligations of the pension plan.  Investments are made in public 
securities  to  ensure  adequate  liquidity  to  support  benefit  payments.  
Domestic and international stocks and bonds provide diversification to 
the portfolio.  The target allocation range for global equity investment 

is  20%-25%  which  includes  large,  mid  and  small  cap  companies  and 
investments  in  both  developed  and  emerging  markets.    The  target 
allocation for bond investments is 60%, which predominately includes 
corporate  bonds.    Long  duration  fixed  income  assets  are  utilized  to 
mitigate the sensitivity of funding ratios to changes in interest rates.  The 
target allocation range for non-public investments in private equity and 
real estate is 5%-15%, and is used to enhance returns and offer additional 
asset  diversification.    The  target  allocation  range  for  commodities  is 
0%-5%, which provides some inflation protection to the portfolio.

Credit Risk

Liquidity Risk

58% of domestic plan assets are invested in long duration bonds.  The 
average rating for  these bonds is A.  These bonds are subject  to credit 
risk, such that a decline in credit ratings for the underlying companies, 
countries or assets (for asset-backed securities) would result in a decline 
in the value of the bonds.  These bonds are also subject to default risk.

Currency Risk

12%  of  domestic  assets  are  valued  in  non-U.S.  dollar  denominated 
investments that are subject to currency fluctuations.  The value of these 
securities will decline if the U.S. dollar increases in value relative to the 
value of the currencies in which these investments are denominated.

10% of the domestic securities are invested in Level 3 securities.  These 
are  long-term  investments  in  private  equity  and  private  real  estate 
investments  that  may  not  mature  or  be  sellable  in  the  near-term 
without significant loss.

At December 31, 2016 and 2015, the amount of Corning common stock 
included in equity securities was not significant.

Cash Flow Data

In  2017,  we  do  not  anticipate  making  voluntary  cash  contributions 
to  our  domestic  defined  benefit  plan  and  expect  to  make  voluntary 
contributions of approximately $23 million to our international defined 
benefit plans.

CORNING INCORPORATED - 2016 Annual ReportNotes to Consolidated Financial Statements

We are required, at the time a guarantee is issued, to recognize a liability 
for  the  fair  value  or  market  value  of  the  obligation  it  assumes.  In  the 
normal course of our business, we do not routinely provide significant 
third-party  guarantees.  Generally,  third-party  guarantees  provided 
by  Corning  are  limited  to  certain  financial  guarantees,  including 
stand-by letters of credit and performance bonds, and the incurrence of 

contingent liabilities in the form of purchase price adjustments related 
to attainment of milestones. These guarantees have various terms, and 
none of these guarantees are individually significant.

We  believe  a  significant  majority  of  these  guarantees  and  contingent 
liabilities will expire without being funded.

liability  accruals  at  December  31,  2016  and 

Corning  is  a  defendant  in  various  lawsuits  and  is  subject  to  various 
claims  that  arise  in  the  normal  course  of  business.  In  the  opinion  of 
management,  the  likelihood  that  the  ultimate  disposition  of  these 
matters  will  have  a  material  adverse  effect  on  Corning’s  consolidated 
financial  position,  liquidity,  or  results  of  operations,  is  remote.  Other 
than  certain  asbestos  related  claims,  there  are  no  other  material  loss 
contingencies related to litigation.

Corning  has  been  named  by  the  Environmental  Protection  Agency 
(the  Agency)  under  the  Superfund  Act,  or  by  state  governments 
under  similar  state  laws,  as  a  potentially  responsible  party  for  17 
active  hazardous  waste  sites.  Under  the  Superfund  Act,  all  parties 
who  may  have  contributed  any  waste  to  a  hazardous  waste  site, 
identified  by  the  Agency,  are  jointly  and  severally  liable  for  the  cost 
of  cleanup  unless  the  Agency  agrees  otherwise.  It  is  Corning’s  policy 

to  accrue  for  its  estimated  liability  related  to  Superfund  sites  and 
other environmental liabilities related  to property owned by Corning 
based  on  expert  analysis  and  continual  monitoring  by  both  internal 
and  external  consultants.  At  December  31,  2016  and  December  31, 
2015,  Corning  had  accrued  approximately  $43  million  (undiscounted) 
and $37 million (undiscounted), respectively, for the estimated liability 
for  environmental  cleanup  and  related  litigation.  Based  upon  the 
information developed to date, management believes that the accrued 
reserve  is  a  reasonable  estimate  of  the  Company’s  liability  and  that 
the risk of an additional loss in an amount materially higher than that 
accrued is remote.

The  ability  of  certain  subsidiaries  and  affiliated  companies  to  transfer 
funds  is  limited  by  provisions  of  foreign  government  regulations, 
affiliate  agreements  and  certain  loan  agreements.  At  December  31, 
2016, the amount of equity subject to such restrictions for consolidated 
subsidiaries  and  affiliated  companies  was  not  significant.  While  this 
amount is legally restricted, it does not result in operational difficulties 
since  we  have  generally  permitted  subsidiaries  to  retain  a  majority  of 
equity to support their growth programs.

15.  Hedging Activities

Corning is exposed to interest rate and foreign currency risks due to the 
movement of these rates.

The areas in which exchange rate fluctuations affect us include:

• Financial  instruments  and  transactions  denominated  in  foreign 

currencies, which impact earnings; and

• The  translation  of  net  assets  in  foreign  subsidiaries  for  which  the 
functional currency is not the U.S. dollar, which impacts our net equity.

Our most significant foreign currency exposures relate to the Japanese 
yen,  South  Korean  won,  New  Taiwan  dollar,  Chinese  yuan,  and  the 
euro.  We  seek  to  mitigate  the  impact  of  exchange  rate  movements 
in  our  income  statement  by  using  over-the-counter  (OTC)  derivative 
instruments including foreign exchange forward and option contracts. 
In  general,  these  hedges  expire  coincident  with  the  timing  of  the 
underlying foreign currency commitments and transactions.

We  are  exposed  to  potential  losses  in  the  event  of  non-performance 
by  our  counterparties  to  these  derivative  contracts.  However,  we 
minimize  this  risk  by  maintaining  a  diverse  group  of  highly-rated 
major international financial institutions. We do not expect to record 
any  losses  as  a  result  of  such  counterparty  default.  Neither  we  nor 
our  counterparties  are  required  to  post  collateral  for  these  financial 
instruments.  The  Company  qualified  for  and  elected  the  end-user 
exception to the mandatory swap clearing requirement of the Dodd-
Frank Act.

Cash Flow Hedges

Our cash flow hedging activities utilize OTC foreign exchange forward 
contracts and options  to reduce  the risk  that movements in exchange 

76

rates will adversely affect the net cash flows resulting from the sale of 
products to foreign customers and purchases from foreign suppliers. Our 
cash flow hedging activity also uses interest rate swaps  to reduce  the 
risk of increases in benchmark interest rates on the probable issuance of 
debt and associated interest payments. In the fourth quarter of 2014, the 
Company entered into interest rate swap agreements to hedge against 
the variability in cash flows due to changes in the benchmark interest 
rate related to an anticipated issuance. The instruments were designated 
as cash flow hedges. In the first quarter of 2015, these interest rate swaps 
were settled prior to the issuance of the anticipated debt. Because the 
Company continued  to anticipate  that  the debt issuance would occur, 
it  entered  into  two  interest  rate  swap  agreements  in  the  first  quarter 
of  2015  to  hedge  against  the  variability  in  cash  flows  due  to  changes 
in  the benchmark interest rate related  to an anticipated issuance. The 
instruments were designated as cash flow hedges, and were settled on 
May 5, 2015. Concurrent with  the settlement of  the interest rate swap 
agreements, Corning issued $375 million of 1.50% senior unsecured notes 
that mature on May 8, 2018 and $375 million of 2.90% senior unsecured 
notes that mature on May 15, 2022.

Corning  uses  a  regression  analysis  to  monitor  the  effectiveness  of  its 
cash  flow  hedges  both  prospectively  and  retrospectively.  Through 
December  31,  2016,  the  hedge 
ineffectiveness  related  to  these 
instruments  is  not  material.  Corning  defers  net  gains  and  losses 
related to effective portion of cash flow hedges into accumulated other 
comprehensive  income  (loss)  on  the  consolidated  balance  sheet  until 
such time as the hedged item impacts earnings. At December 31, 2016, 
the amount expected to be reclassified into earnings within the next 12 
months is a pre-tax net loss of $28 million.

CORNING INCORPORATED - 2016 Annual ReportFair Value Hedges

In  October  of  2012,  we  entered  into  two  interest  rate  swaps  that  are 
designated as fair value hedges and economically exchange a notional 
amount of $550 million of previously issued fixed rate long-term debt to 
floating rate debt. Under the terms of the swap agreements, we pay the 
counterparty a floating rate that is indexed to the one-month LIBOR rate.

Corning  utilizes  the  long  haul  method  for  effectiveness  analysis,  both 
retrospectively  and  prospectively.  The  analysis  excludes  the  impact  of 
credit  risk  from  the  assessment  of  hedge  effectiveness.  The  amount 
recorded in current period earnings in the other (expense) income, net 
component,  relative  to  ineffectiveness,  is  nominal  for  the  year  ended 
December 31, 2016.

Net  gains  and  losses  from  fair  value  hedges  and  the  effects  of  the 
corresponding hedged item are recorded on  the same line item in  the 
consolidated statements of income.

Undesignated Hedges

Corning also uses OTC foreign exchange forward and option contracts 
that are not designated as hedging instruments for accounting purposes. 
The undesignated hedges limit exposures to foreign functional currency 
fluctuations related to certain subsidiaries’ monetary assets, monetary 
liabilities and net earnings in foreign currencies.

A significant portion of the Company’s non-U.S. revenues and expenses 
are  denominated  in  Japanese  yen,  South  Korean  won,  New  Taiwan 
dollar,  Chinese  yuan  and  euro.  When  these  revenues  and  expenses 
are  translated  back  to  U.S.  dollars,  the  Company  is  exposed  to  foreign 
exchange  rate  movements.  To  protect  translated  earnings  against 
movements in these currencies, the Company has entered into a series 
of zero-cost collars and average rate forwards.

Notes to Consolidated Financial Statements

With a zero-cost collar structure, the Company writes a local currency call 
option and purchases a local currency put option or vice versa. The zero-
cost collars offset the impact of translated earnings above the put price 
and below the call strike price and that offset is reported in Translated 
earnings contract (loss) gain, net. The Company entered into a series of 
zero-cost  collars,  settling  quarterly,  to  hedge  the  effect  of  translation 
impact for each respective quarter. The zero-cost collar program hedges 
exposures through 2022 and 2017 for the Japanese yen and Korean won, 
respectively. Due  to  the nature of  the instruments, only either  the put 
option or the call option can be exercised at maturity. As of December 31, 
2016, the U.S. dollar net notional value of the Japanese yen and Korean 
won zero-cost collars is $1 billion.

The  Company  extended  its  foreign  exchange  hedge  program  in  2016 
and  entered  into  a  series  of  average  rate  forwards.  These  will  hedge 
a  significant  portion  of  its  projected  yen  exposure  for  the  period  of 
2018-2022. As of December 31, 2016, the U.S. dollar net notional value of 
the  yen  average  rate  forwards  program  is  $14  billion. The  average  rate 
forward program was also expanded to partially hedge the impact of the 
South Korean won, New Taiwan dollar, Chinese yuan and euro translation 
on the Company’s projected net income. As of December 31, 2016 these 
average  rate  forwards  have  a  total  notional  value  of  $1  billion.  The 
entire average rate forward program will settle net without obligation 
to deliver Japanese yen, Korean won, New Taiwan dollar, Chinese yuan 
and euro.

The fair value of these derivative contracts are recorded as either assets 
(gain position) or liabilities (loss position) on the Consolidated Balance 
Sheet. Changes in the fair value of the derivative contracts are recorded 
currently in earnings in the Translated earnings contract (loss) gain, net 
line of the Consolidated Statement of Income.

The following  table summarizes  the notional amounts and respective fair values of Corning’s derivative financial instruments on a gross basis for

16.  Fair Value Measurements

Fair  value  standards  under  U.S.  GAAP  define  fair  value,  establish  a 
framework  for  measuring  fair  value  in  applying  generally  accepted 
accounting  principles,  and  require  disclosures  about  fair  value 
measurements.  The  standards  also  identify  two  kinds  of  inputs 
that  are  used  to  determine  the  fair  value  of  assets  and  liabilities: 
observable  and  unobservable.  Observable  inputs  are  based  on  market 
data  or  independent  sources  while  unobservable  inputs  are  based 

on  the  Company’s  own  market  assumptions.  Once  inputs  have  been 
characterized,  the  inputs  are  prioritized  into  one  of  three  broad 
levels  (provided  in  the  table  below)  used  to  measure  fair  value.  Fair 
value  standards  apply  whenever  an  entity  is  measuring  fair  value 
under  other  accounting  pronouncements  that  require  or  permit  fair 
value  measurement  and  require  the  use  of  observable  market  data 
when available.

The following tables provide fair value measurement information for the Company’s major categories of financial assets and liabilities measured on 
a recurring basis:

As  a  result  of  the  acquisition  of  Samsung  Corning  Precision  Materials 
in  January  2014,  the  Company  has  contingent  consideration  that 
was  measured  using  unobservable  (Level  3)  inputs.  This  contingent 
consideration arrangement potentially requires additional consideration 
to be paid between the parties in 2018: one based on projections of future 
revenues generated by  the business of Corning Precision Materials for 
the period between the acquisition date and December 31, 2017, which 
is subject to a cap of $665 million; and another based on the volumes of 
certain sales during the same period, which is subject to a separate cap 
of $100 million. The fair value of the potential receipt of the contingent 
consideration in 2018 in the amount of $196 million recognized on the 
acquisition  date  was  estimated  by  applying  an  option  pricing  model 
using  the  Company’s  projection  of  future  revenues  generated  by 
Corning Precision Materials. Changes in the fair value of the contingent 
consideration in future periods are valued using an option pricing model 
and are recorded in Corning’s results in the period of the change.

On  December  29,  2015,  Corning  and  Samsung  Display  entered  into 
an  agreement  pursuant  to  which  Corning  exchanged  the  amount  of 
contingent  consideration  in  excess  of  $300  million  (net  present  fair 
value:  $246  million),  as  consideration  for  the  incremental  fair  value

associated  with  a  number  of  commercial  agreements,  including  the 
amendment of its long-term supply agreement with Samsung Display. 
As  of  December  29,  2015,  the  net  present  fair  value  of  the  contingent 
consideration receivable was $458 million. The net present fair value of 
the commercial benefit associated with the amended long-term supply 
agreement  exceeds  the  value  exchanged  by  Corning  pursuant  to  this 
agreement (net present fair value: $212 million). Consequently, Corning 
reclassified  this  amount  to  the  other  asset  line  of  the  Consolidated 
Balance Sheet and will amortize the amount over the remaining term of 
the long-term supply agreement as a reduction in revenue.

As  of  December  31,  2016  and  2015,  the  fair  value  of  the  potential 
receipt  of  the  contingent  consideration  in  2018  was  $289  million  and 
$246 million, respectively.

There were no significant financial assets and liabilities measured on a 
nonrecurring basis during the years ended December 31, 2016 and 2015.

17.  Shareholders’ Equity

Fixed Rate Cumulative Convertible Preferred 
Stock, Series A
On  January  15,  2014,  Corning  designated  a  new  series  of  its  preferred 
stock  as  Fixed  Rate  Cumulative  Convertible  Preferred  Stock,  Series  A, 
par value $100 per share, and issued 1,900 shares of Preferred Stock at 
an  issue  price  of  $1  million  per  share,  for  an  aggregate  issue  price  of 
$1.9 billion, to Samsung Display in connection with the acquisition of its 
equity  interests  in  Samsung  Corning  Precision  Materials.  Corning  also 
issued to Samsung Display an additional amount of Preferred Stock at 
closing, for an aggregate issue price of $400 million in cash.

Dividends  on  the  Preferred  Stock  are  cumulative  and  accrue  at  the 
annual  rate  of  4.25%  on  the  per  share  issue  price  of  $1  million.  The 
dividends are payable quarterly as and when declared by the Company’s 
Board of Directors. The Preferred Stock ranks senior to our common stock 
with respect to payment of dividends and rights upon liquidation. The 
Preferred Stock is not redeemable except in the case of a certain deemed 
liquidation  event,  the  occurrence  of  which  is  under  the  control  of  the 
Company. The Preferred Stock is convertible at the option of the holder 
and  the  Company  upon  certain  events,  at  a  conversion  rate  of  50,000 
shares  of  Corning’s  common  stock  per  one  share  of  Preferred  Stock, 
subject to certain anti-dilution provisions. As of December 31, 2016, the 
Preferred  Stock  has  not  been  converted,  and  none  of  the  anti-dilution 
provisions have been triggered. Following the seventh anniversary of the 
closing of the acquisition of Samsung Corning Precision Materials, the 
Preferred Stock will be convertible, in whole or in part, at the option of 
the holder. The Company has  the right, at its option,  to cause some or 
all of the shares of Preferred Stock to be converted into Common Stock, 
if, for 25 trading days (whether or not consecutive) within any period of 
40 consecutive trading days, the closing price of Common Stock exceeds 
$35 per share. If  the aforementioned right becomes exercisable before 
the seventh anniversary of the closing, the Company must first obtain 
the written approval of the holders of a majority of the Preferred Stock 
before exercising its conversion right. The Preferred Stock does not have 
any voting rights except as may be required by law.

Share Repurchases

2014 Share Repurchases

On  March  4,  2014,  as  part  of  the  $2  billion  share  repurchase  program 
announced on October 22, 2013 and made effective concurrent with the 
closing of Corning’s acquisition of Samsung Corning Precision Materials 
on  January  15,  2014  (the  “March  2014  Repurchase  Program”),  Corning 
entered  into  an  ASR  agreement  (the  “2014  ASR  agreement”)  with 
Citibank N.A. (“Citi”). Under the 2014 ASR agreement, Corning agreed to 
purchase $1.25 billion of its common stock, with an initial delivery by Citi 
of 52.5 million shares based on the current market price, and payment 
of  $1.25  billion  made  by  Corning  to  Citi.  The  2014  ASR  agreement 
was  completed  on  May  28,  2014,  and  Corning  received  an  additional 
8.7  million  shares  to  settle  the  2014  ASR  agreement.  In  total,  Corning 
repurchased  61.2  million  shares  based  on  the  average  daily  volume 
weighted-average price of Corning’s common stock during the term of 
the 2014 ASR agreement, less a discount.

In addition to the shares repurchased through the 2014 ASR agreement, 
in the year ended December 31, 2014, we repurchased 36.9 million shares 
of  common  stock  on  the  open  market  for  approximately  $750  million, 
as  part  of  the  March  2014  Repurchase  Program.  This  program  was 
completed  in  the  fourth  quarter  of  2014,  with  a  total  of  98.1  million 
shares repurchased for approximately $2 billion.

80

On  December  3,  2014,  Corning’s  Board  of  Directors  authorized 
the  repurchase  of  up  to  $1.5  billion  shares  of  common  stock  (the 
“December  2014  Repurchase  Program”)  between  the  date  of 
announcement and December 31, 2016.

2015 Share Repurchases

On  July  15,  2015,  Corning’s  Board  of  Directors  approved  a  $2  billion 
share  repurchase  program  (the  “July  2015  Repurchase  Program”)  and 
on  October  26,  2015  the  Board  of  Directors  authorized  an  additional 
$4  billion  share  repurchase  program  (together  with  the  July  2015 
Repurchase  Program,  the  “2015  Repurchase  Programs”).  The  2015 
Repurchase  Programs  permit  Corning  to  effect  repurchases  from  time 
to  time  through  a  combination  of  open  market  repurchases,  privately 
negotiated transactions, advance repurchase agreements and/or other 
arrangements.

On  October  28,  2015,  Corning  entered  into  an  ASR  with  Morgan 
Stanley  and  Co.  LLC  (“Morgan  Stanley”)  to  repurchase  $1.25  billion  of 
Corning’s common stock (the “2015 ASR agreement”). The 2015 ASR was 
executed under the July 2015 Repurchase Program. Under the 2015 ASR 
agreement,  Corning  made  a  $1.25  billion  payment  to  Morgan  Stanley 
on  October  29,  2015  and  received  an  initial  delivery  of  approximately 
53.1 million shares of Corning common stock from Morgan Stanley on the 
same day. On January 19, 2016, the 2015 ASR agreement was completed. 
Corning received an additional 15.9 million shares on January 22, 2016 to 
settle  the  2015  ASR  agreement.  In  total,  Corning  purchased  69  million 
shares  based  on  the  average  daily  volume  weighted-average  price  of 
Corning’s  common  stock  during  the  term  of  the  2015  ASR  agreement, 
less a discount.

In addition to the shares repurchased through the 2015 ASR agreement, 
we repurchased 98 million shares of common stock on the open market 
for approximately $2 billion, as part of the December 2014 Repurchase 
Program and  the July 2015 Repurchase Program,  resulting  in a  total of 
167 million shares repurchased for $3.25 billion during 2015.

2016 Share Repurchases

In  July  2016,  Corning  entered  into  an  accelerated  share  repurchase 
agreement  (the  “2016  ASR  agreement”)  under  the  2015  Repurchase 
Program with Morgan Stanley  to repurchase Corning’s common stock. 
Under the 2016 ASR agreement, Corning made a $2.0 billion payment to 
Morgan Stanley in July and received an initial delivery of approximately 
74.4  million  shares  of  Corning  common  stock  on  the  same  day.  The 
transaction  was  structured  with  two  tranches  resulting  in  a  total  of 
12.3  million  shares  being  delivered  to  Corning  in  the  fourth  quarter 
of  2016,  for  a  total  of  86.7  million  shares  repurchased  under  the  2016 
ASR agreement.

In  addition  to  the  2016  ASR  agreement,  during  the  year  ended 
December  31,  2016,  the  Company  repurchased  110  million  shares  of 
common stock on the open market for approximately $2.2 billion as part 
of its 2015 Repurchase Programs, resulting in a total of 197.1 million shares 
repurchased for $4.2 billion during 2016.

18.  Earnings Per Common Share

Basic  earnings  per  common  share  are  computed  by  dividing  income  attributable  to  common  shareholders  by  the  weighted-average  number  of 
common shares outstanding for the period. Diluted earnings per common share assumes the issuance of common shares for all potentially dilutive 
securities outstanding.

The reconciliation of the amounts used to compute basic and diluted earnings per common share from operations follows (in millions, except per 
share amounts):

Net income attributable to Corning Incorporated

Less: Series A convertible preferred stock dividend

Net income available to common stockholders - basic

Plus: Series A convertible preferred stock dividend

Net income available to common stockholders - diluted

Weighted-average common shares outstanding - basic

Effect of dilutive securities:

Stock options and other dilutive securities

Series A convertible preferred stock 

Weighted-average common shares outstanding - diluted

Basic earnings per common share

Diluted earnings per common share

Anti-dilutive potential shares excluded from diluted earnings per common share:

19.  Share-based Compensation

Stock Compensation Plans
Corning  maintains  long-term  incentive  plans  (the  “Plans”)  for  key 
employees and non-employee members of our Board of Directors. The 
Plans  allow  us  to  grant  equity-based  compensation  awards,  including 
stock  options,  stock  appreciation  rights,  performance  share  units, 
restricted  stock  units,  restricted  stock  awards  or  a  combination  of 
awards  (collectively,  share-based  awards).  At  December  31,  2016,  there 
were  approximately  69  million  unissued  common  shares  available  for 
future grants under the Plans.

The Company measures and recognizes compensation cost for all share-
based  payment  awards  made  to  employees  and  directors  based  on 
estimated fair values.

The fair value of awards granted subsequent to January 1, 2006 that are 
expected to ultimately vest is recognized as expense over the requisite 
service  periods.  The  number  of  options  expected  to  vest  equals  the 
total  options  granted  less  an  estimation  of  the  number  of  forfeitures 
expected to occur prior to vesting. The forfeiture rate is calculated based 
on 15 years of historical data and is adjusted if actual forfeitures differ 
significantly  from  the  original  estimates.  The  effect  of  any  change 

in  estimated  forfeitures  would  be  recognized  through  a  cumulative 
adjustment that would be included in compensation cost in the period 
of the change in estimate.

Total  share-based  compensation  cost  of  $42  million,  $46  million  and 
$58  million  was  disclosed  in  operating  activities  on  the  Company’s 
Consolidated Statements of Cash Flows for the years ended December 31, 
2016, 2015 and 2014, respectively.

Stock Options
Corning’s stock option plans provide non-qualified and incentive stock 
options to purchase authorized but unissued shares, or treasury shares, 
at the market price on the grant date and generally become exercisable 
in installments from one to five years from the grant date. The maximum 
term of non-qualified and incentive stock options is 10 years from  the 
grant date.

The following table summarizes information concerning stock options 
outstanding including the related transactions under the stock option 
plans for the year ended December 31, 2016:

The aggregate intrinsic value (market value of stock less option exercise 
price) in the preceding table represents the total pretax intrinsic value, 
based  on  the  Company’s  closing  stock  price  on  December  30,  2016, 
which  would  have  been  received  by  the  option  holders  had  all  option 
holders exercised their “in-the-money” options as of that date. The total 
number  of  “in-the-money”  options  exercisable  on  December  31,  2016, 
was approximately 18 million.

An  award  is  considered  vested  when  the  employee’s  retention  of  the 
award  is  no  longer  contingent  on  providing  subsequent  service  (the 
“non-substantive  vesting  period  approach”).  Awards  to  retirement 
eligible employees are fully vested at the date of grant, and the related 
compensation  expense  is  recognized  immediately  upon  grant  or  over 
the period from  the grant date  to  the date of retirement eligibility for 
employees that become age 55 during the vesting period.

The weighted-average grant-date fair value for options granted for the 
years ended December 31, 2016, 2015 and 2014 was $6.31, $7.99 and $8.29, 
respectively. The total fair value of options that vested during the years 
ended December 31, 2016, 2015 and 2014 was approximately $22 million, 
$36 million and $16 million, respectively. Compensation cost related  to 
stock options for the years ended December 31, 2016, 2015 and 2014, was 
approximately $11 million, $14 million and $22 million, respectively.

As  of  December  31,  2016,  there  was  approximately  $6  million  of 
unrecognized compensation cost related to stock options granted under 
the Plans. The cost is expected to be recognized over a weighted-average 
period of 1.7 years.

Proceeds received from the exercise of stock options were $138 million 
for the year ended December 31, 2016, which were included in financing 
activities  on  the  Company’s  Consolidated  Statements  of  Cash  Flows. 
The  total  intrinsic  value  of  options  exercised  for  the  years  ended 
December  31,  2016,  2015  and  2014  was  approximately  $53  million, 
$48 million and $69 million, respectively. The income tax benefit realized 
from share-based compensation was not significant for the years ended 
December 31, 2016, 2015 and 2014. Refer to Note 6 (Income Taxes).

Corning  uses  a  multiple-point  Black-Scholes  valuation  model  to 
estimate  the  fair  value  of  stock  option  grants.  Corning  utilizes  a 
blended approach for calculating the volatility assumption used in the 
multiple-point Black-Scholes valuation model defined as  the weighted 
average  of  the  short-term  implied  volatility,  the  most  recent  volatility 
for the period equal to the expected term, and the most recent 15-year 
historical volatility. The expected term assumption is the period of time 
the  options  are  expected  to  be  outstanding,  and  is  calculated  using  a 
combination  of  historical  exercise  experience  adjusted  to  reflect  the 
current  vesting  period  of  options  being  valued,  and  partial  life  cycles 
of  outstanding  options.  The  risk-free  rates  used  in  the  multiple-point 
Black-Scholes  valuation  model  are  the  implied  rates  for  a  zero-coupon 
U.S. Treasury bond with a term equal to the option’s expected term. The 
ranges  given  below  reflect  results  from  separate  groups  of  employees 
exhibiting different exercise behavior.

Incentive Stock Plans
The Corning Incentive Stock Plan permits restricted stock and restricted 
stock  unit  grants,  either  determined  by  specific  performance  goals  or 
issued directly, in most instances, subject to the possibility of forfeiture 
and  without  cash  consideration.  Restricted  stock  and  restricted  stock 
units under the Incentive Stock Plan are granted at the closing market 
price on the grant date, contingently vest over a period of generally one 
to ten years, and generally have contractual lives of one to ten years. The 
fair value of each restricted stock grant or restricted stock unit awarded 
under the Incentive Stock Plan is based on the grant date closing price 
of the Company’s stock.

Time-Based Restricted Stock and Restricted Stock Units:

Time-based  restricted  stock  and  restricted  stock  units  are  issued  by 
the  Company  on  a  discretionary  basis,  and  are  payable  in  shares  of 
the  Company’s  common  stock  upon  vesting.  The  fair  value  is  based 
on the closing market price of the Company’s stock on the grant date. 
Compensation cost is recognized over the requisite vesting period and 
adjusted for actual forfeitures before vesting.

The following table represents a summary of the status of the Company’s 
non-vested time-based restricted stock and restricted stock units as of 
December 31, 2015, and changes which occurred during the year ended 
December 31, 2016:

As  of  December  31,  2016,  there  was  approximately  $25  million  of 
unrecognized  compensation  cost  related  to  non-vested  time-based 
restricted stock and restricted stock units compensation arrangements 
granted  under  the  Plan.  The  cost  is  expected  to  be  recognized  over  a 
weighted-average period of 2.1 years. The total fair value of time-based 
restricted stock that vested during the years ended December 31, 2016, 
2015 and 2014 was approximately $27 million, $32 million and $32 million, 
respectively.  Compensation  cost  related  to  time-based  restricted  stock 
and  restricted  stock  units  was  approximately  $31  million,  $32  million 
and  $36  million  for  the  years  ended  December  31,  2016,  2015  and 
2014, respectively.

All  other  segments  that  do  not  meet  the  quantitative  threshold 
for  separate  reporting  have  been  grouped  as  “All  Other.”  This  group 
is  primarily  comprised  of  the  results  of  Corning’s  Pharmaceutical 
Technologies  business,  our  non-LCD  glass  business,  new  product  lines 
and development projects, as well as certain corporate investments such 
as Eurokera and Keraglass equity affiliates.

We prepared the financial results for our reportable segments on a basis 
that is consistent with the manner in which we internally disaggregate 
financial information to assist in making internal operating decisions. We 
included the earnings of equity affiliates that are closely associated with 
our  reportable  segments  in  the  respective  segment’s  net  income. We 
have allocated certain common expenses among reportable segments 
differently  than  we  would  for  stand-alone  financial  information. 
Segment  net  income  may  not  be  consistent  with  measures  used  by 
other  companies. The  accounting  policies  of  our  reportable  segments 
are the same as those applied in the Consolidated Financial Statements.

(1)  Depreciation expense for Corning’s reportable segments includes an allocation of depreciation of corporate property not specifically identifiable to 

a segment.

(2) Research, development and engineering expenses include direct project spending that is identifiable to a segment.

(3) Many of Corning’s administrative and staff functions are performed on a centralized basis. Where practicable, Corning charges  these expenses 
to segments based upon the extent to which each business uses a centralized function. Other staff functions, such as corporate finance, human 
resources and legal are allocated to segments, primarily as a percentage of sales.

(4) Segment  assets  include  inventory,  accounts  receivable,  property,  plant  and  equipment,  net  of  accumulated  depreciation,  and  associated  equity 

companies and cost investments.

Cover: Glass is remarkably versatile. To date, scientists have combined silica with approximately 
50 elements to develop unique glass compositions. But we have the potential to use the entire  
Periodic  Table  in  countless  combinations.  To  drive  that  point  home,  imagine  you’re  holding  
an  Oxford  English  Dictionary  in  your  hands  and  think  of  how  many  words  we  can  make  using  
only 26 letters. That’s why we believe some of the greatest glass innovations are still ahead.

Corning is one of the world’s 
leading innovators in materials 
science. For more than 165 years, 
Corning has applied its unparalleled 
expertise in specialty glass, ceramics, 
and optical physics to develop products 
that have created new industries 
and transformed people’s lives.
