Chairman of the Board, 
Chief Executive Officer & President

To Our Shareholders:
Corning entered 2015 with a goal to Build on Our 
Momentum and Grow. We understand that growth 
is an ongoing process and the path is rarely linear, 
so we did not expect to declare “mission accom-
plished” at year’s end. However, we encountered 
global economic headwinds and other challenges 
that lowered our growth expectations as the year 
progressed, despite increasing our momentum 
in several key areas. Fortunately, Corning is well-
equipped to navigate these challenges. 

More than a decade of outstanding industrial 
performance has given us a strong foundation on 
which to build. Since 2004, we have grown sales, 
net income, earnings per share, and operating cash 
flow at close to double-digit rates. We’ve outper-
formed our competitors in our major segments. 
We’ve achieved the lowest-cost manufacturing 
position in key businesses. And we’ve created more 
than $1.5 billion in entirely new revenue streams 
by launching disruptive products such as Corning® 
Gorilla® Glass.

This track record of performance has created a rich 
set of opportunities and strong cash flow that make 
us confident in our ability to deliver sustainable 
growth and continue creating value for shareholders.

2015 Performance Highlights

Before I turn to Corning’s strategy for 2016 
and the years ahead, let’s review Corning’s 2015 
performance. 

Core sales were $9.8 billion; core earnings were 
$1.88 billion; and core earnings per share were 
$1.40. Those numbers reflect the weak global 
economy and foreign currency fluctuations, which 
impacted most of our businesses. However, strong 
results in Optical Communications helped offset 
challenges in other areas.

Here’s a closer look at how each of our major 
businesses performed: 

n  In Display Technologies, sales were down from 
  2014 due to lower demand for LCD televisions  
  and IT products. However, LCD glass price declines 
  were the smallest they have been in five years, 
  despite the worst display industry environment 

in five years.

n  Optical Communications sales were up year over 
year, driven by strong demand for fiber to the 

  home and data centers in North America.

n   In Specialty Materials, Gorilla Glass volume was 
  up versus 2014. However, segment sales were 
  down overall due to the completion of a large 
  aerospace and defense program, softer demand 
in the semiconductor industry, and the weaker 

  euro.

n   Environmental Technologies sales were down 
year over year due to the declining euro and 
  end-market weakness in China for both passenger 

cars and heavy-duty diesel trucks.

n   In Life Sciences, sales were lower than expected, 
  due to the weak euro.

Despite the economic headwinds, growth in Optical 
Communications was sufficient to produce aggre-
gate growth in our non-Display segments. These 
results once again demonstrate the value of our 
diverse business portfolio.

New Growth Drivers

Corning grows primarily through innovation. 
We invest strongly in research, development, and 
engineering (RD&E) to innovate in our existing busi-
nesses, while also creating entirely new businesses 
to drive growth in the years ahead. We then supple-
ment that organic growth by pursuing acquisitions 
and ventures to enhance our product portfolio and 
extend our market access.

In 2015, we introduced several new products and 
advanced key innovation programs. 

n   We launched Corning Lotus® NXT Glass, which 
  has become the leading glass substrate for 
  high-performance displays.

n   The first televisions to use our new Corning 
Iris™ Glass as a light-guide plate became 
commercially available.

n   We introduced our EDGE8™ solution, a new 
full-connectivity system for data centers.  

n   We commercialized FLORA™ substrates, which 
reduce the dangerous emissions that occur 

  upon engine startup.

n   We expanded our drug-discovery portfolio 
  with the introduction of HepatoCells™ for 
toxicology and drug metabolism studies, 
  and TransportoCells™ for testing drug-drug 

interactions.

n  We reached a major milestone in our efforts 

to extend Gorilla Glass into new markets, with 
  Ford’s introduction of the Ford GT. This is the first 
  production vehicle to use Gorilla Glass for multiple  
  glazing applications, including the windshield, 
rear engine cover, and acoustic separation wall.

We faced challenges as well. The exact timing and 
impact of innovations remain difficult to predict.  
The adoption of some products (such as Gorilla 
Glass 4) proceeded more quickly than anticipated, 
while others (such as our ONE™ Cellular Solutions) are 
proceeding more slowly. However, when we assess 
Corning’s overall innovation portfolio, we are pleased 
with the robustness of our pipeline and the oppor-
tunities for both near-term and long-term growth. 

On the acquisition front, we extended our leader-
ship in Optical Communications with the addition 
of TR Manufacturing, Inc.; Samsung Electronics Co., 
Ltd.’s fiber business; and iBwave Solutions. These 
acquisitions had an immediate positive impact on 
Corning’s bottom line, in addition to improving 
our competitive position. We also acquired 
Gerresheimer’s glass tubing business and entered 
into an equity venture to capture an exciting        
opportunity in pharmaceutical packaging that we 
believe has the potential to become a very signifi-
cant new business.

Our Strategy and Capital Allocation Framework

Let’s turn to how we are focusing Corning’s portfolio 
and utilizing our financial strength to drive growth 
and create value for shareholders.

Capital Allocation Plans

We expect to generate more than $20 billion 
between 2016 and 2019. In October 2015, we 
announced our plan to invest $10 billion of that cash 
in RD&E, capital expenditures, and acquisitions to 
drive growth in the years ahead. We also announced 
that we will distribute at least $10 billion (approxi-
mately half of our current market cap) to sharehold-
ers. We are committed to increasing the dividend 
by at least 10 percent annually through 2019, and 
we will continue to be opportunistic on share 
repurchases. We are executing on that commitment. 
Last October, Corning’s board of directors increased 
our repurchase authorization by $4 billion; between 
October 2015 and January of this year, we executed 
a $1.25 billion accelerated share repurchase; and in 
February, our board authorized a 12.5 percent quar-
terly common stock dividend increase.

Focus > 80% of resources on opportunities that leverage capabilities from at least two of three columns.

Focusing Our Portfolio

The core of what Corning does is invent, make, and 
sell. We create value by inventing category-defining 
products, using transformative manufacturing plat-
forms, and building strong, trust-based relationships 
with global leaders in their industries. We’re seek-
ing to augment that value-creation through a more 
focused and cohesive portfolio that improves our 
probability of success, reduces the cost of innovation, 
and increases the barriers to entry.   

The framework focuses our portfolio on a set of 
reinforcing capabilities with strong inter-connections. 
Corning’s best-in-the-world capabilities include 
three core technologies, four manufacturing and 
engineering platforms, and five market-access 
platforms. Our probability of success increases 
as we apply more of these world-class capabilities; 
our cost of innovation declines as we re-apply talent 
and leverage our existing assets; and we create 
higher, more sustainable competitive barriers 
when we combine multiple capabilities.

Focusing our portfolio means we are directing 80 
percent or more of our resources to opportunities 
that draw from at least two of these three capabili-
ties sets. Few competitors can match our expertise 
in any one of our focus capabilities, and when we 
combine capabilities, we can create market-leading 
positions and margins. Of course, we recognize that 
Corning is the natural leader for some great oppor-
tunities that do not require multiple capabilities. 
Our framework allows us to apply up to 20 percent 
of our resources on these opportunities. However, 
we know that those initiatives are riskier, so we only 
pursue them if the potential payoff is exceptional.

We developed this approach based on experience. 
Gorilla Glass is a great example of re-applying talent 
and leveraging our manufacturing and market- 
access platforms. To develop Gorilla Glass, we 
re-applied our expertise in glass science to deliver 
a new-to-the-world product faster and at lower cost 
than anyone else could have done. To manufacture 
it, we used fusion technology and manufacturing 
assets built for our Display business. That saved 
us about $800 million in capital, significantly 
enhancing our return on investment.

296423_Corning_Narr_R2.indd   3

Our track record in Optical Communications 
demonstrates how combining capabilities creates 
higher and more sustainable competitive advantages. 
Using glass science, optical physics, and vapor 
deposition, we have dramatically increased the 
performance and lowered the cost of optical fiber. 
Ceramic science helped us improve connectors and 
reduce signal loss. We use extrusion to make cabling. 
And we use precision forming to make connectors. 
Not only have our customers benefited from this 
combination of our world-class capabilities, we’ve 
benefited as well. For instance, in the passive 
optical markets we serve, we capture 20 percent 
of the revenue, but 30 percent of the profits.

Focusing our portfolio also means that we will peri-
odically add assets that complement our capabilities 
and divest or realign assets that fall outside our core 
capabilities. In December, we announced our plans 
to exchange Corning’s 50 percent interest in Dow 
Corning Corporation for a subsidiary that will hold 
approximately 40 percent ownership in Hemlock 
Semiconductor Group and $4.8 billion in cash. We 
believe this transaction creates significant value for 
shareholders. The realignment will be accretive to 
Corning’s EPS, and our position in Hemlock allows 
us to capture potential upside from a rebound in 
the solar market. The $4.8 billion is approximately 
30 times the equity earnings from Dow Corning’s 
silicones business, and we expect the realignment 
to be essentially tax free.

Opportunities Ahead

Corning’s technologies and manufacturing plat-
forms are becoming increasingly relevant to a broad 
range of industries, as illustrated in our depiction 
of The Glass Age (opposite page). For example, 
automakers are looking to make cars lighter, 
safer, sleeker, and more interactive, which creates 
disruptive innovation opportunities for Corning.

We believe Gorilla Glass offers compelling benefits 
including lighter weight for better fuel economy 
and vehicle handling; toughness and damage 
resistance to make vehicles safer and more durable; 
and an optically advantaged surface for head-up 
displays and touch technology. Best of all, we can 
leverage our existing capabilities and trust-based 
relationships to develop the new products. The 
automotive industry represents a potential glass 
market larger in square feet than the current LCD 
market, so we are understandably excited about 
this opportunity. In January, we entered into a joint 
venture with Saint-Gobain Sekurit to produce light-
weight auto glazing. We look forward to providing 
updates on this initiative and other growth oppor-
tunities as we progress.

Closing Thoughts

No doubt, we will continue to face challenges 
in 2016. But we’re confident in Corning’s long-
term growth prospects and our ability to execute, 
because we have a strong record of performance, a 
robust innovation portfolio, and distinct capabilities 
that are becoming increasingly vital. Most impor-
tantly, we always keep our eyes on the prize — 
not just another 165 years of innovation and 
independence for Corning, but also a world with 
cleaner air, unlimited bandwidth, more effective 
medicine, richer entertainment experiences, and 
more efficient communication. When you invest 
in Corning, you are investing in that world, too. 
Thank you for helping us bring it to life.

Sincerely,

Wendell P. Weeks
Chairman of the Board, 
Chief Executive Officer, and President

Business Description

General

Corning  traces  its  origins  to  a  glass  business  established  in  1851.  The 
present  corporation  was  incorporated  in  the  State  of  New  York  in 
December 1936. The Company’s name was changed from Corning Glass 
Works to Corning Incorporated on April 28, 1989.

Corning Incorporated is one of the world’s leading innovators in materials 
science.  For  more  than  160  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. 
We succeed through sustained investment in research and development, 
a  unique  combination  of  material  and  process  innovation,  and  close 
collaboration  with  customers  to  solve  tough  technology  challenges. 
Corning  operates  in  five  reportable  segments:  Display  Technologies, 
Optical  Communications,  Environmental  Technologies,  Specialty 
Materials and Life Sciences, and manufactures and processes products at 
approximately 89 plants in 17 countries.

Display Technologies Segment
Corning’s  Display Technologies  segment  manufactures  glass  substrates 
for liquid crystal displays (“LCDs”) that are used primarily in LCD televisions, 
notebook  computers  and  flat  panel  desktop  monitors.  This  segment 
develops,  manufactures  and  supplies  high  quality  glass  substrates 
using  technology  expertise  and  a  proprietary  fusion  manufacturing 
process, which Corning invented and is the cornerstone of the Company’s 
technology leadership in the LCD industry. The highly automated process 
yields  glass  substrates  with  a  pristine  surface  and  excellent  thermal 
dimensional  stability  and  uniformity  –  essential  attributes  for  the 
production of large, high performance LCDs. Corning’s fusion process is 
scalable and we believe it is the most cost effective process in producing 
large size substrates.

We  are  recognized  for  providing  product  innovations  that  enable  our 
customers  to  produce  larger,  lighter,  thinner  and  higher-resolution 
displays more affordably. Some of the product innovations that we have 
launched over the past ten years utilizing our world-class processes and 
capabilities include the following:

• EAGLE  XG®,  the  industry’s  first  LCD  glass  substrate  that  is  free  of 

heavy metals;

• EAGLE  XG®  Slim  glass,  a  line  of  thin  glass  substrates  which  enables 
lighter-weight portable devices and thinner televisions and monitors;

• Corning®  Willow™  Glass,  our  ultra-thin  flexible  glass  for  use  in  next-
generation consumer electronic technologies, including curved displays 
for  immersive  viewing  or  mounting  on  non-flat  surfaces. This  glass  is 
also  used  in  a  variety  of  non-display  applications,  such  as  decorative

interior  architecture  and  advanced  semiconductor 
packaging; and

• The  family  of  Corning  Lotus™  Glass,  high-performance  display  glass 
developed  to  enable  cutting-edge  technologies,  including  organic 
light-emitting diode (“OLED”) displays and next generation LCDs. These 
substrate  glasses  provide  industry-leading  levels  of  low  total  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  Materials  on 
January 15, 2014.

In the fourth quarter of 2015, Corning announced that with the support of 
the Hefei government it will locate a Gen 10.5 glass manufacturing facility 
adjacent  to  the  BOE Technology  Group  Co.  Ltd.  (BOE)  plant  in  the  Hefei 
XinZhan  General  Pilot  Zone  in  Anhui  Province,  China.  Glass  substrate 
production  from  the  new  facility  is  expected  to  support  BOE’s  plan  to 
begin mass production of LCD panels for large-size televisions by the third 
quarter of 2018.

As  part  of  this  investment,  Corning  and  BOE  have  entered  into  a  long-
term  supply  agreement  that  commits  BOE  to  the  purchase  of  Gen 
10.5  glass  substrates  from  the  Corning  manufacturing  facility  in  Hefei. 
BOE also has extended its long-term supply agreement with Corning to 
purchase glass substrates for Gen 8.5 and smaller sizes. This investment 
will enable Corning to become the first manufacturer of TFT-grade Gen 
10.5 substrates. At 2,940 mm x 3,370 mm, Gen 10.5 will be the largest LCD 
glass substrate available, providing the most economical cuts for 65-inch 
and  75-inch  televisions.  The  Gen  10.5  substrates  manufactured  at  the 
Hefei facility will use Corning® EAGLE XG® slim glass.

certain precious metals, and various batch materials.

Although  energy  shortages  have  not  been  a  problem  recently,  the  cost 
of  energy  remains  volatile.  Corning  has  achieved  flexibility  through 
engineering  changes  to  take  advantage  of  low-cost  energy  sources 
in  most  significant  processes.  Specifically,  many  of  Corning’s  principal 
manufacturing  processes  can  be  operated  with  natural  gas,  propane, 
oil  or  electricity,  or  a  combination  of  these  energy  sources.  Additionally, 
in the fourth quarter of 2015, we entered into a 25-year power purchase 
agreement  for  solar-generated  electricity  in  which  we  will  purchase 
62.5% of the expected output of a solar power facility in North Carolina. 
This  is  a  major  step  in  Corning’s  commitment  to  reduce  its  carbon 
footprint  and  continues  our  long  history  of  being  an  environmentally 
conscious company.

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 batch materials and precious metals. For many products, 
Corning has alternate glass compositions that would allow operations to 
continue without interruption in the event of specific materials shortages.

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.  Any  future  difficulty  in  obtaining 
sufficient and timely delivery of components could result in lost sales due 
to delays or reductions in product shipments, or reductions in Corning’s 
gross margins.

Patents and Trademarks

Inventions  by  members  of  Corning’s  research  and  engineering  staff 
continue  to  be  important  to  the  Company’s  growth.  Patents  have 
been  granted  on  many  of  these  inventions  in  the  United  States  and 
other  countries.  Some  of  these  patents  have  been  licensed  to  other 
manufacturers,  including  companies  in  which  Corning  has  equity 
investments. Many of our earlier patents have now expired, but Corning 
continues to seek and obtain patents protecting its innovations. In 2015, 
Corning was granted about 420 patents in the U.S. and over 740 patents 
in countries outside the U.S.

Each business segment possesses a patent portfolio that provides certain 
competitive advantages in protecting Corning’s innovations. Corning has 
historically enforced, and will continue to enforce, its intellectual property 
rights.  At  the  end  of  2015,  Corning  and  its  wholly-owned  subsidiaries 
owned  over  7,750  unexpired  patents  in  various  countries  of  which  over 
3,250  were  U.S.  patents.  Between  2016  and  2017,  approximately  6%  of 
these patents will expire, while at the same time Corning intends to seek 
patents protecting its newer innovations. Worldwide, Corning has about 
9,170  patent  applications  in  process,  with  about  2,350  in  process  in  the 
U.S. Corning believes  that its patent portfolio will continue  to provide a 
competitive advantage in protecting the Company’s innovation, although 
Corning’s competitors in each of its businesses are actively seeking patent 
protection as well.

The  Display  Technologies  segment  has  over  1,430  patents  in  various 
countries, of which about 340 are U.S. patents. No one patent is considered 
material  to  this  business  segment.  Some  of  the  important  U.S.-issued 
patents  in  this  segment  include  patents  relating  to  glass  compositions 
and methods for the use and manufacture of glass substrates for display 
applications.  There  are  six  important  Display  Technologies  segment 
patents set to expire between 2016 and 2018.

The  Optical  Communications  segment  has  over  2,730  patents  in 
various countries, of which over 1,270 are U.S. patents. No one patent  is 
considered  material  to  this  business  segment.  Some  of  the  important 
U.S.-issued patents in this segment include: (i) patents relating to optical

Corning has entered into cross-licensing arrangements with some major 
competitors, but the scope of such licenses has been limited to specific 
product areas or technologies.

Corning’s  principal  trademarks  include  the  following:  Corning,  Celcor, 
ClearCurve, DuraTrap, Eagle XG, Epic, Gorilla, HPFS, Pyrex, Steuben, Falcon, 
SMF-28e, and Willow.

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 continuing operations were approximately $14 million 
in 2015 and are estimated to be $26 million in 2016.

Corning’s  2015  consolidated  operating  results  were  charged  with 
approximately $45 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.

included in, or incorporated by reference into, this Annual Report on Form 
10-K.

Risk Factors

We operate in rapidly changing economic and technological 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, 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 risks is not all inclusive but is designed to highlight what we 
believe are important factors to consider, as these factors could cause our 
future results to differ from those in the forward-looking statements and 
from historical trends.

As a global company, we face many risks which could adversely impact 
our ongoing operations and reported financial results

We are a global company and derive a substantial portion of our revenues 
from,  and  have  significant  operations,  outside  of  the  United  States. 
Our  international  operations  include  manufacturing,  assembly,  sales, 
research and development, customer support, and shared administrative 
service centers.

Compliance with laws and regulations increases our costs. These laws and 
regulations  include  U.S.  laws  and  local  laws  which  include  data  privacy 
requirements,  employment  and  labor  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.

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

• General economic conditions in each country or region;

• Many  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 generally;

• Differing 

legal  systems, 

including  protection  and  treatment  of 

intellectual property and patents;

• Complex or unclear tax regimes;

• Complex  tariffs,  trade  duties  and  other  trade  barriers  including 

anti-dumping duties;

• Difficulty 

in 

collecting  obligations  owed 

to  us 

such  as 

accounts receivable;

• Natural  disasters  such  as  floods,  earthquakes,  tsunamis  and 

windstorms; and

• Potential power loss or disruption affecting manufacturing.

Our sales could be negatively impacted by the actions of one or more key 
customers, or the circumstances to which they are subject, leading to the 
substantial reduction in orders for our products

In 2015, Corning’s ten largest customers accounted for 45% of our sales.

A relatively small number of customers accounted for a high percentage 
of net sales in our reportable segments. For 2015, three customers of the 
Display Technologies  segment  accounted  for  62%  of  total  segment  net 
sales when combined. In  the Optical Communications segment in 2015, 
two  customers  accounted  for  22%  of  total  segment  net  sales  when 
combined.  In  the  Environmental  Technologies  segment  in  2015,  three 
customers accounted for 86% of total segment sales in aggregate. In the 
Specialty Materials segment, three customers accounted for 56% of total 
segment sales in 2015 when combined. In the Life Sciences segment, two 
customers accounted for 46% of total segment sales in 2015 in aggregate. 
As a result of mergers and consolidations between customers, Corning’s 
customer base could become more concentrated.

CORNING INCORPORATED - 2015 Annual ReportRisk Factors

We face pricing pressures in each of our businesses that could adversely 
affect our financial performance

We face pricing pressure in each of our businesses as a result of intense 
competition, emerging technologies, or over-capacity. We may not be able 
to achieve proportionate reductions in costs or sustain our current rate of 
cost reduction to offset pricing pressures. We anticipate pricing pressures 
will continue in the future in all our businesses.

Any of these items could cause our sales, profitability and cash flows to 
be significantly reduced.

We face risks due to foreign currency fluctuations

Because we have significant customers and operations outside the U.S., 
fluctuations  in  foreign  currencies,  especially  the  Japanese  yen,  New 
Taiwan  dollar,  South  Korean  won,  and  euro,  will  significantly  impact 
our  sales,  profit  and  cash  flows.  Foreign  exchange  rates  may  make  our 
products  less  competitive  in  countries  where  local  currencies  decline  in 
value  relative  to  the  U.S.  dollar  and  Japanese  yen.  Sales  in  our  Display 
Technologies  segment,  representing  34%  of  Corning’s  sales  in  2015,  are 
denominated  in  Japanese  yen.  Corning  hedges  significant  translation, 
transaction  and  balance  sheet  currency  exposures  and  uses  a  variety 
of  derivative  instruments  to  reduce  the  impact  of  foreign  currency 
fluctuations  associated  with  certain  monetary  assets  and  liabilities  as 
well as operating results including our net profits.

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, net of gains or losses from our 
hedging programs. For example, we will experience foreign currency gains 
and losses in certain instances if it is not possible or cost effective to hedge 
our  foreign  currency  exposures  or  should  we  elect  not  to  hedge  certain 
foreign  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. 
The  objective  of  our  hedging  activities  is  to  mitigate  the  risk  associated 
with foreign currency exposures. We are also exposed  to potential losses 
in the event of non-performance by our counterparties to these derivative 
contracts. Neither we nor our counterparties are required to post collateral 
for  these  financial  instruments.  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  currency  exchange 
rates associated with these exposures and changes in those rates, whether 
we  have  entered  into  foreign  currency  forward  contracts  to  offset  these 
exposures and other factors. 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.

Our  Optical  Communications  segment  customers’  purchases  of  our 
products  are  affected  by  their  capital  expansion  plans,  general  market 
and economic uncertainty and regulatory changes, including broadband 
policy. Sales in the Optical Communications segment are expected to be 
impacted  by  the  pace  of  fiber-to-the-premises  deployments  and  data 
center  expansions.  Our  sales  will  be  dependent  on  planned  targets  for 
homes passed and connected and construction of new and/or expansion 
of  existing  data  centers.  Changes  in  our  customers’  deployment  plans 
could adversely affect future sales.

In  the  Environmental  Technologies  segment,  sales  of  our  ceramic 
substrate and filter products for automotive and diesel emissions tend to 
fluctuate with vehicle production. Changes in laws and regulations for air 
quality and emission controls may also influence future sales. Sales in our 
Environmental Technologies segment are mainly to three catalyzers and 
emission system control manufacturers. Our customers sell these systems 
to automobile and diesel engine original equipment manufacturers. Sales 
in this segment may be affected by adverse developments in the global 
vehicle  or  freight  hauling  industries  or  by  such  factors  as  higher  fuel 
prices that may affect vehicle sales or downturns in freight traffic.

Certain  sales  in  our  Specialty  Materials  segment  track  worldwide 
economic cycles and our customers’ responses to those cycles. In addition, 
any positive trends in prior years in the sales of strengthened glass may 
not continue. We may experience losses relating to our inability to supply 
contracted quantities of this glass and processes planned to produce new 
versions of this glass may not be successful.

Sales  in  our  Life  Sciences  segment  are  concentrated  with  two  large 
distributors who are also competitors, and the balance is to a variety of 
pharmaceutical and biotechnology companies, hospitals, universities, and 
other research facilities. Changes in our distribution arrangements in this 
segment may adversely affect this segment’s financial results.

Our operations and financial performance could be negatively impacted, 
if  the  markets  for  our  products  do  not  develop  and  expand  as  we 
anticipate

The  markets  for  our  products  are  characterized  by  rapidly  changing 
technologies, evolving industry or regulatory standards and new product 
introductions. Our success is dependent on the successful introduction of 
new products, or upgrades of current products, and our ability to compete 
with  new  technologies.  The  following  factors  related  to  our  products 
and markets, if they do not continue as in the recent past, could have an 
adverse impact on our operations:

• our ability  to introduce advantaged products such as glass substrates 
for  liquid  crystal  displays,  optical  fiber  and  cable  and  hardware  and 
equipment,  and  environmental  substrate  and  filter  products  at 
competitive prices;

• our  ability  to  manufacture  glass  substrates  and  strengthened  glass, 
to  satisfy  our  customers’  technical  requirements  and  our  contractual 
obligations; and

• our  ability  to  develop  new  products  in  response  to  government 

regulations and laws.

9

CORNING INCORPORATED - 2015 Annual ReportRisk Factors

If  the  financial  condition  of  our  customers  declines,  our  credit  risks 
could increase

If  our  products,  including  materials  purchased  from  our  suppliers, 
experience performance issues, our business will suffer

We have experienced, and in the future may experience, losses as a result 
of our inability to collect our accounts receivable. If our customers or our 
indirect customers fail to meet their payment obligations for our products, 
we could experience reduced cash flows and losses in excess of amounts 
reserved.  Many  customers  of  our  Display  Technologies  and  Specialty 
Materials  segments  are  thinly  capitalized  and/or  unprofitable.  In  our 
Optical  Communications  segment,  certain  large  infrastructure  projects 
are subject to governmental funding, which, if terminated, could adversely 
impact the financial strength of our customers. These factors may result in 
an inability to collect receivables or a possible loss in business.

Our  business  depends  on  the  production  of  products  of  consistently 
high  quality.  Our  products,  components  and  materials  purchased  from 
our  suppliers,  are  typically  tested  for  quality.  These  testing  procedures 
are  limited  to  evaluating  our  products  under  likely  and  foreseeable 
failure  scenarios.  For  various  reasons,  our  products,  including  materials 
purchased from our suppliers, may fail to perform as a customer expected. 
In some cases, product redesigns or additional expense may be required 
to address such issues. A significant or systemic quality issue could result 
in  customer  relations  problems,  lost  sales,  reduced  volumes,  product 
recalls and financial damages and penalties.

The success of our business depends on our ability to develop and produce 
advantaged products that meet our customers’ needs

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

Our  business  relies  on  continued  global  demand  for  our  brands  and 
products. To  achieve  business  goals,  we  must  develop  and  sell  products 
that  appeal  to  our  customers,  original  equipment  manufacturers  and 
distributors. This is dependent on a number of factors, including our ability 
to manage and maintain key customer relationships, our ability to produce 
products  that  meet  the  quality,  performance  and  price  expectations  of 
our  customers.  The  manufacturing  of  our  products  involves  complex 
and  precise  processes.  In  some  cases,  existing  manufacturing  may  be 
insufficient to achieve the requirements of our customers. We will need 
to  develop  new  manufacturing  processes  and  techniques  to  maintain 
profitable operations. While we continue to fund projects to improve our 
manufacturing  techniques  and  processes  and  lower  our  costs,  we  may 
not achieve satisfactory manufacturing costs that will fully enable us to 
meet our profitability targets.

In addition, our continued success in selling products that appeal to our 
customers is dependent on our ability to innovate, with respect to both 
products  and  operations,  and  on  the  availability  and  effectiveness  of 
legal protection for our innovations. Failure to continue to deliver quality 
and competitive products to the marketplace, to adequately protect our 
intellectual  property  rights,  to  supply  products  that  meet  applicable 
regulatory requirements or to predict market demands for, or gain market 
acceptance of, our products, could have a negative impact on our business, 
results of operations and financial condition.

Our  future  financial  performance  depends  on  our  ability  to  purchase  a 
sufficient amount of materials, precious metals, parts, and manufacturing 
equipment to meet the demands of our customers

Our ability to meet customer demand depends, in part, on our ability to 
obtain timely and adequate delivery of materials, precious metals, 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.  Furthermore,  certain 
manufacturing  equipment,  raw  materials  or  components  are  available 
only  from  a  single  source  or  limited  sources.  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 or energy, 
could have a material adverse effect on our businesses.

At  December  31,  2015,  Corning  had  goodwill  and  other  intangible  assets 
of  $2,086  million.  In  the  fourth  quarter  of  2015,  we  recorded  a  charge 
of  $29  million  for  the  impairment  of  goodwill  resulting  from  a  small 
acquisition in 2014. 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.

We operate in a highly competitive environment

We operate in a highly competitive environment, and our outlook depends 
on the company’s share of industry sales based on our ability to compete 
with others in the marketplace. The Company competes on the basis of 
product  attributes,  customer  service,  quality  and  price. There  can  be  no 
assurance  that  our  products  will  be  able  to  compete  successfully  with 
other companies’ products. Our share of industry sales could be reduced 
due  to aggressive pricing or product strategies pursued by competitors, 
unanticipated product or manufacturing difficulties, product performance 
failures,  our  failure  to  price  our  products  competitively,  our  failure  to 
produce  our  products  at  a  competitive  cost  or  unexpected,  emerging 
technologies  or  products.  We  expect  that  we  will  face  continuous 
competition  from  existing  competitors,  low  cost  manufacturers  and 
new entrants. We believe we must invest in research and development, 
engineering,  manufacturing  and  marketing  capabilities,  and  continue 
to improve customer service in order  to remain competitive. We cannot 
provide  assurance  that  we  will  be  able  to  maintain  or  improve  our 
competitive position.

We may need to change our pricing models to compete successfully

We  face  intense  competition  in  all  of  our  businesses,  particularly  LCD 
glass,  and  general  economic  and  business  conditions  can  put  pressure 
on us to change our prices. If our competitors offer significant discounts 
on certain products or develop products that the marketplace considers 
more valuable, we may need to lower prices or offer other favorable terms 
in order to retain our customers and market positions. Any such changes 
may  reduce  our  profitability  and  cash  flow.  Any  broad-based  change  to 
our prices and pricing policies could cause our revenues to decline or be 
delayed as we implement and our customers adjust  to  the new pricing 
policies.  If  we  do  not  adapt  our  pricing  models  to  reflect  changes  in 
customer  use  of  our  products  or  changes  in  customer  demand,  our 
revenues could decrease.

10

CORNING INCORPORATED - 2015 Annual ReportLCD glass generates a significant amount of the Company’s profits and 
cash flow, and any events that adversely affect the market for LCD glass 
substrates  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  level  of  profitability  of  our  LCD  glass  business.  As  a 
result,  any  event  that  adversely  affects  our  Display  business  could  have 
a  significant  impact  on  our  consolidated  financial  results. These  events 
could  include  loss  of  patent  protection,  increased  costs  associated  with 
manufacturing, and increased competition from the introduction of new, 
and more desirable products. If any of these events had a material adverse 
effect on the sales of our LCD glass, such an event could result in material 
charges and a significant reduction in profitability.

Additionally,  emerging  material  technologies  could  replace  our  glass 
substrates  for  certain  applications,  including  display  glass,  cover  glass 
and others, resulting in a decline in demand for our products. Existing or 
new  production  capacity  for  glass  substrates  may  exceed  the  demand 
for  them.  Technologies  for  displays,  cover  glass  and  other  applications 
in competition with our glass may reduce or eliminate the need for our 
glass substrates. New process technologies developed by our competitors 
may  also  place  us  at  a  cost  or  quality  disadvantage.  Our  own  process 
technologies  may  be  acquired  or  used  unlawfully  by  others,  enabling 
them to compete with us. Our inability to manufacture glass substrates 
to  the  specifications  required  by  our  customers  may  result  in  loss  of 
revenue, margins and profits or liabilities for failure to supply. A scarcity of 
resources, limitations on technology, personnel or other factors resulting 
in  a  failure  to  produce  commercial  quantities  of  glass  substrates  could 
have adverse financial consequences to us.

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 
factors, including:

impacted  by  several 

• 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 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 
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.

Risk Factors

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  on  foreign 
earnings. Although we cannot predict whether or in what form proposed 
legislation may pass, if enacted certain anti-deferral proposals could have 
a material adverse impact on our tax expense and cash flow.

Our  business  depends  on  our  ability  to  attract  and  retain  talented 
employees

The  loss  of  the  services  of  any  member  of  our  senior  management 
team  or  key  research  and  development  or  engineering  personnel 
without adequate replacement, or  the inability  to attract new qualified 
personnel,  could  have  a  material  adverse  effect  on  our  operations  and 
financial performance.

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  toward  adopting  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.

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.

11

CORNING INCORPORATED - 2015 Annual ReportRisk Factors

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.

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.

We may not capture significant revenues from our current research and 
development efforts for several years, if at all

Developing our products through research and development is expensive 
and the investment often involves a long return on investment cycle. We 
have  made  and  expect  to  continue  to  make  significant  investments  in 
research and development and related product opportunities. Accelerated 
product introductions and short product life cycles require high levels of 
expenditures  for  research  and  development  that  could  adversely  affect 
our  operating  results  if  not  offset  by  increases  in  our  gross  margin. We 
believe  that  we  must  continue  to  dedicate  a  significant  amount  of 
resources  to  our  research  and  development  efforts  to  maintain  our 
competitive position.

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.

Additionally,  a  significant  amount  of  the  specialized  manufacturing 
capacity  for  our  Display Technologies  segment  is  concentrated  in  three 
overseas countries 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 and the customers’ locations, it may not be possible to find 
replacement  capacity  quickly  or  substitute  production  from  facilities  in 
other countries. Accordingly, loss of these facilities could produce a near-
term severe impact on our Display business and the Company as a whole.

We face risks through equity affiliates that we do not control

Corning’s net income includes equity earnings from affiliated companies. 
For  the  year  ended  December  31,  2015,  we  recognized  $299  million  of 
equity  earnings,  of  which  approximately  94%  came  from  Dow  Corning 
(which makes silicone and high purity polycrystalline products).

On  December  11,  2015,  Corning  announced  its  intention  to  exchange  its 
50%  equity  interest  in  Dow  Corning  for  100%  of  the  stock  of  a  newly 
formed  entity  that  will  become  a  wholly-owned  subsidiary  of  Corning 
Incorporated.  The  newly  formed  entity  will  hold  approximately  40% 
ownership 
in  Hemlock  Semiconductor  Group  and  approximately 
$4.8  billion  in  cash.  Upon  completion  of  this  strategic  realignment, 
which is expected to close during the first half of 2016, Dow Chemical, an 
equal owner of Dow Corning with Corning since 1943, will assume 100% 
ownership of Dow Corning.

Going  forward,  we  face  the  risk  that  our  other  equity  investments  may 
not  perform  at  the  levels  expected.  In  addition,  we  rely  on  the  internal 
controls  and  financial  reporting  controls  of  these  entities  and  their 
failure to maintain effectiveness or comply with applicable standards or 
regulations may adversely affect us.

We may not have adequate insurance coverage for claims against us

We face the risk of loss resulting from product liability, asbestos, securities, 
fiduciary  liability,  intellectual  property,  antitrust,  contractual,  warranty, 
environmental, fraud and other lawsuits, whether or not such claims are 
valid.  In  addition,  our  product  liability,  fiduciary,  directors  and  officers, 
property policies including business interruption, natural catastrophe and 
comprehensive general liability insurance may not be adequate to cover 
such claims or may not be available to the extent we expect in the future. 
A  successful  claim  that  exceeds  or  is  not  covered  by  our  policies  could 
require us to make substantial unplanned payments. Some of the carriers 
in our historical primary and excess insurance programs are in liquidation 
and  may  not  be  able  to  respond  if  we  should  have  claims  reaching 
their  policies.  The  financial  health  of  other  insurers  may  deteriorate. 
Several of our insurance carriers are litigating with us the extent, if any, 
of  their  obligation  to  provide  insurance  coverage  for  asbestos  liabilities 
asserted  against  us.  The  results  of  that  litigation  may  adversely  affect 
our  insurance  coverage  for  those  risks.  In  addition,  we  may  not  be  able 
to  obtain  adequate  insurance  coverage  for  certain  types  of  risk  such  as 
political risks, terrorism or war.

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  Antiboycott  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 violations 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.

12

CORNING INCORPORATED - 2015 Annual ReportRisk Factors

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

The  Company  is  increasingly  dependent  on  sophisticated  information 
technology  and  infrastructure.  Any  significant  breakdown,  intrusion, 
interruption or corruption of these systems or data breaches could have a 
material adverse effect on our business. Like other global companies, we 
have, from time to time, experienced incidents related to our information 
technology (“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.

We  use  electronic  IT  in  our  manufacturing  processes  and  operations 
and  other  aspects  of  our  business.  Our  IT  systems  may  be  vulnerable 
to  disruptions  from  computer  viruses,  natural  disasters,  unauthorized 
access, cyber-attack and other similar disruptions. 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,  reduce  the  value  of  our  investment  in  research 
and development and other strategic initiatives, or otherwise adversely 
affect our business.

Additionally, utilities and other operators of critical energy 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.).

International  trade policies may impact demand for our products and 
our competitive position

Government  policies  on  international  trade  and  investment  such  as 
import quotas, capital controls or tariffs, 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  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.

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.

Acquisitions,  equity  investments  and  strategic  alliances  may  have  an 
adverse effect on our business

We  expect  to  continue  making  acquisitions  and  entering  into  equity 
investments  and  strategic  alliances  as  part  of  our  business  strategy. 
These  transactions  involve  significant  challenges  and  risks  including 
that a  transaction may not advance our business strategy,  that we do 
not realize a satisfactory return on our investment, or that we experience 
difficulty integrating new employees, business systems, and technology, 
or  diversion  of  management’s  attention  from  our  other  businesses. 
It  may  take  longer  than  expected  to  realize  the  full  benefits,  such  as 
increased  revenue  and  cash  flow,  enhanced  efficiencies,  or  market 
share, or those benefits may ultimately be smaller than anticipated, or 
may not be realized. These events could harm our operating results or 
financial condition.

Improper disclosure of personal data could result in liability and harm 
our reputation

We  store  and  process  personally-identifiable  information  of  our 
employees  and,  in  some  case,  our  customers.  At  the  same  time,  the 
continued  occurrence  of  high-profile  data  breaches  provides  evidence 
of  the  increasingly  hostile  information  security  environment.  This 
environment  demands  that  we  continuously  improve  our  design 
and  coordination  of  security  controls  across  our  business  groups  and 
geographies.  Despite  these  efforts,  it  is  possible  our  security  controls 
over  personal  data,  our  training  of  employees  and  vendors  on  data 
security,  and  other  practices  we  follow  may  not  prevent  the  improper 
disclosure  of  personally  identifiable  information.  Improper  disclosure 
of this information could harm our reputation or subject us to liability 
under  laws  that  protect  personal  data,  resulting  in  increased  costs  or 
loss of revenue.

Significant macroeconomic events, changes in regulations, or a crisis in 
the financial markets could limit our access to capital

We utilize credit in both the capital markets and from banks to facilitate 
company  borrowings,  hedging  transactions,  leases  and  other  financial 
transactions.  We  maintain  a  $2  billion  revolving  credit  agreement  to 
fund potential liquidity needs and to backstop certain transactions. An 
adverse  macroeconomic  event  or  changes  in  bank  regulations  could 
limit our ability to gain access to credit or to renew the revolving credit 
agreement upon expiration. Additionally, a financial markets crisis may 
limit our ability to access liquidity.

Adverse economic conditions may adversely affect our cash investments

We maintain an investment portfolio of various types of securities with 
varying  maturities  and  credit  quality.  These  investments  are  subject 
to  general  credit,  liquidity,  market,  and  interest  rate  risks,  which  may 
be  exacerbated  by  unusual  events  that  have  affected  global  financial 
markets.  We  also  make  significant  investments  in  U.S.  government 
securities,  either  directly,  or  through  investment  in  money  market 
funds. If global credit and equity markets experience prolonged periods 
of  decline,  or  if  the  U.S.  defaults  on  its  debt  obligations  or  its  debt  is 
downgraded, our investment portfolio may be adversely impacted and 
we  could  determine  that  more  of  our  investments  have  experienced 
an  other-than-temporary  decline  in  fair  value,  requiring  impairment 
charges that could adversely impact our financial results.

CORNING INCORPORATED - 2015 Annual ReportLegal Proceedings

Dow Corning Corporation� Corning and Dow Chemical each own 50% of 
the common stock of Dow Corning.

Dow Corning Breast Implant Litigation

In  May  1995,  Dow  Corning  filed  for  bankruptcy  protection  to  address 
pending  and  claimed  liabilities  arising  from  many  thousands  of  breast 
implant  product  lawsuits.  On  June  1,  2004,  Dow  Corning  emerged  from 
Chapter  11  with  a  Plan  of  Reorganization  (the  “Plan”)  which  provided 
for  the  settlement  or  other  resolution  of  implant  claims. The  Plan  also 
includes  releases  for  Corning  and  Dow  Chemical  as  shareholders  in 
exchange for contributions to the Plan.

Under the terms of the Plan, Dow Corning has established and is funding 
a  Settlement Trust  and  a  Litigation  Facility  to  provide  a  means  for  tort 
claimants  to  settle  or  litigate  their  claims.  Inclusive  of  insurance,  Dow 
Corning has paid approximately $1.8 billion to the Settlement Trust. As of 
December 31, 2015, Dow Corning had recorded a reserve for breast implant 
litigation  of  $291  million.  See  Note  7  (Investments)  to  the  Consolidated 
Financial Statements for additional detail.

Other Dow Corning Claims Arising From Bankruptcy Proceedings

As  a  separate  matter  arising  from  the  bankruptcy  proceedings,  Dow 
Corning  is  defending  claims  asserted  by  a  number  of  commercial 
creditors who claim additional interest at default rates and enforcement 
costs,  during  the  period  from  May  1995  through  June  2004.  As  of 
December 31, 2015, Dow Corning has estimated the liability to commercial 
creditors to be within the range of $104 million to $341 million. As Dow 
Corning  management  believes  no  single  amount  within  the  range 
appears  to  be  a  better  estimate  than  any  other  amount  within  the 
range,  Dow  Corning  has  recorded  the  minimum  liability  within  the 
range.  Should  Dow  Corning  not  prevail  in  this  matter,  Corning’s  equity 
earnings would be reduced by its 50% share of the amount in excess of 
$104 million, net of applicable tax benefits. There are a number of other 
claims  in  the  bankruptcy  proceedings  against  Dow  Corning  awaiting 
resolution  by  the  U.S.  District  Court,  and  it  is  reasonably  possible  that 
Dow  Corning  may  record  bankruptcy-related  charges  in  the  future. The 
remaining tort claims against Dow Corning are expected to be channeled 
by the Plan into facilities established by the Plan or otherwise defended 
by the Litigation Facility.

Pittsburgh Corning Corporation and Asbestos Litigation� Corning and PPG 
Industries,  Inc.  (“PPG”)  each  own  50%  of  the  capital  stock  of  Pittsburgh 
Corning  Corporation  (“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. 
On  April  16,  2000,  PCC  filed  for  Chapter  11  reorganization  in  the  U.S. 
Bankruptcy  Court  for  the Western  District  of  Pennsylvania.  At  the  time 
PCC  filed  for  bankruptcy  protection,  there  were  approximately  11,800 
claims pending against Corning in state court lawsuits alleging various 
theories  of  liability  based  on  exposure  to  PCC’s  asbestos  products  and 
typically  requesting  monetary  damages  in  excess  of  one  million  dollars 
per claim. Corning has defended those claims on the basis of the separate 
corporate status of PCC and the absence of any facts supporting claims of 
direct liability arising from PCC’s asbestos products.

PCC Plan of Reorganization

Corning, with other relevant parties, has been involved in ongoing efforts 
to  develop  a  Plan  of  Reorganization  that  would  resolve  the  concerns 
and objections of the relevant courts and parties. On November 12, 2013, 
the  Bankruptcy  Court  issued  a  decision  finally  confirming  an  Amended 
PCC  Plan  of  Reorganization  (the “Amended  PCC  Plan”  or  the “Plan”).  On 
September  30,  2014,  the  United  States  District  Court  for  the  Western 
District  of  Pennsylvania  (the  “District  Court”)  affirmed  the  Bankruptcy 
Court’s decision confirming the Amended PCC Plan. On October 30, 2014, 
one of the objectors to the Plan appealed the District Court’s affirmation 
of the Plan to the United States Court of Appeals for the Third Circuit (the 
“Third Circuit Court of Appeals”). On January 6, 2016, all pending appeals 
of  the  Plan  were  withdrawn  and  Corning  expects  that  the  Plan  will 
become effective in April 2016.

Under  the  Plan  as  affirmed  by  the  Bankruptcy  Court  and  affirmed  by 
the  District  Court,  Corning  is  required  to  contribute  its  equity  interests 
in PCC and Pittsburgh Corning Europe N.V. (“PCE”), a Belgian corporation, 
and to contribute $290 million in a fixed series of payments, recorded at 
present value. Corning will contribute its equity interest in PCC and PCE 
on the Plan’s Funding Effective Date, which is expected to occur in June 
2016. Corning has the option to use its common stock rather than cash 
to make these payments, but the liability is fixed by dollar value and not 
the number of shares. The Plan requires Corning to make: (1) one payment 
of  $70  million  one  year  from  the  date  the  Plan  becomes  effective  and 
certain conditions are met; and (2) five additional payments of $35 million, 
$50 million, $35 million, $50 million and $50 million, respectively, on each of 
the five subsequent anniversaries of the first payment, the final payment 
of which is subject to reduction based on the application of credits under 
certain circumstances.

Non-PCC Asbestos Litigation

In addition to the claims against Corning related to its ownership interest 
in PCC, Corning is also the defendant in approximately 9,700 other cases 
(approximately 37,300 claims) alleging injuries from asbestos related to 
its Corhart business and similar amounts of monetary damages per case 
(the “non-PCC asbestos claims”). When PCC filed for bankruptcy protection, 
the Court granted a preliminary injunction to suspend all asbestos cases 
against PCC, PPG and Corning – including these non-PCC asbestos claims 
(the “Stay”). The Stay remains in place as of the date of this filing; however, 
given that the Amended PCC Plan is now affirmed by the District Court 
and the Third Circuit Court of Appeals, Corning anticipates the Stay will 
be lifted in the second half of 2016. These non-PCC asbestos claims have 
been covered by insurance without material impact to Corning to date. As 
of December 31, 2015, Corning had received for these claims approximately 
$19  million  in  insurance  payments. When  the  Stay  is  lifted,  these  non-
PCC asbestos claims will be allowed to proceed against Corning. In prior 
periods, Corning recorded in its estimated asbestos litigation liability an 
additional $150 million for these and any future non-PCC asbestos claims.

14

CORNING INCORPORATED - 2015 Annual ReportTotal  Estimated  Liability  for  the  Amended  PCC  Plan  and  the  Non-PCC 
Asbestos Claims

The liability for the Amended PCC Plan and the non-PCC asbestos claims 
was estimated to be $678 million at December 31, 2015, compared with an 
estimate of liability of $681 million at December 31, 2014. The $678 million 
liability is comprised of $238 million of the fair value of PCE, $290 million 
for  the  fixed  series  of  payments,  and  $150  million  for  the  non-PCC 
asbestos claims, all referenced in the preceding paragraphs. With respect 
to the PCE liability, at December 31, 2015 and 2014, the fair value of $238 
million  and  $241  million  of  our  interest  in  PCE  significantly  exceeded 
its  carrying  value  of  $154  million  and  $162  million,  respectively.  There 
have  been  no  impairment  indicators  for  our  investment  in  PCE  and  we 
continue to recognize equity earnings of this affiliate. At the time Corning 
recorded  this  liability,  it  determined  it  lacked  the  ability  to  recover  the 
carrying amount of its investment in PCC and its investment was other 
than temporarily impaired. As a result, we reduced our investment in PCC 
to  zero.  As  the  fair  value  in  PCE  is  significantly  higher  than  book  value, 
management  believes  that  the  risk  of  an  additional  loss  in  an  amount 
materially higher than the fair value of the liability is remote. With respect 
to  the  liability  for  other  asbestos  litigation,  the  liability  for  non-PCC 
asbestos  claims  was  estimated  based  upon  industry  data  for  asbestos 
claims since Corning does not have recent claim history due to the Stay 
issued  by  the  Bankruptcy  Court.  The  estimated  liability  represents  the 
undiscounted  projection  of  claims  and  related  legal  fees  over  the  next 
20 years. The amount may need to be adjusted in future periods as more 
data  becomes  available;  however,  we  cannot  estimate  any  additional 
losses  at  this  time.  For  the  years  ended  December  31,  2015  and  2014, 
Corning recorded asbestos litigation income of $15 million and expense 
of  $9  million,  respectively.  At  December  31,  2015,  $440  million  of  the 
obligation, consisting of the $290 million for the fixed series of payments 
and $150 million for the non-PCC asbestos claims, is classified as a non-
current  liability,  as  installment  payments  for  the  cash  portion  of  the 
obligation are not planned to commence until more than 12 months after 
the Amended PCC Plan becomes effective. The amount of the obligation 
related to the fair value of PCE, $238 million, was reclassified to a current 
liability in the fourth quarter of 2015, as the contribution of the assets is 
expected to be made within the next twelve months.

Non-PCC Asbestos Claims Insurance Litigation

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.

Legal Proceedings

Environmental Litigation� Corning has been named by the United States 
Environmental  Protection  Agency  (the  “EPA”)  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 EPA, are jointly and severally liable 
for  the  cost  of  cleanup  unless  the  EPA  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,  2015  and  2014,  Corning  had 
accrued  approximately  $37  million  (undiscounted)  and  $43  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.

Chinese  Anti-Dumping  Investigation  Involving  Optical  Fiber  Preforms 
Produced in the United States� On March 19, 2014, the Chinese Ministry 
of  Commerce  (“MOFCOM”)  initiated  an  anti-dumping  investigation 
involving  optical  fiber  preforms  originating  in  the  United  States  and 
Japan. On July 23, 2015, MOFCOM announced its Final Determination that 
included a dumping margin of 41.79% against Corning. The company is 
evaluating its options to appeal MOFCOM’s decision.

Department  of  Justice  Grand  Jury  Subpoena�  In  March  2012,  Corning 
received  a  grand  jury  subpoena  issued  in  the  United  States  District 
Court  for  the  Eastern  District  of  Michigan  from  the  U.S.  Department 
of  Justice  in  connection  with  an  investigation  into  conduct  relating  to 
possible  antitrust  law  violations  involving  certain  automotive  products, 
including  catalytic  converters,  diesel  particulate  filters,  substrates  and 
monoliths. The subpoena required Corning to produce to the Department 
of  Justice  certain  documents  from  the  period  January  1999  to  March 
2012.  In  November  2012,  Corning  received  another  subpoena  from  the 
Department  of  Justice,  with  the  same  scope,  but  extending  the  time 
frame for the documents to be produced back to January 1, 1988. Corning’s 
policy  is  to  comply  with  all  laws  and  regulations,  including  all  antitrust 
and  competition  laws.  Antitrust  investigations  can  result  in  substantial 
liability for the Company. Currently, Corning cannot estimate the ultimate 
financial  impact,  if  any,  resulting  from  the  investigation.  Such  potential 
impact,  if  an  antitrust  violation  by  Corning  is  found,  could  however,  be 
material to the results of operations of Corning in a particular period.

Strategy and Capital Allocation Framework
In October 2015, Corning announced a new strategy and capital allocation 
framework  that  reflects  the  company’s  financial  and  operational 
strengths, as well as its ongoing commitment to increasing shareholder 
value.

Our  probability  of  success  increases  as  we  invest  in  our  world-
class  capabilities.  Over  the  next  four  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.

Our financial strength also allows us to increase our return to shareholders. 
Through  2019,  we  expect  to  generate  and  deploy  over  $20  billion  in 
cash and to return more than $10 billion to shareholders through share 
repurchases and dividends. As a result, we expect to increase our dividend 
per common share by at least 10% annually through 2019.

Investing in our Future
Corning  is  one  of  the  world’s  leading  innovators  in  materials  science. 
For  more  than  160  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.  Our 
spending  level  for  research,  development  and  engineering  remained 
consistent  at  8%  of  sales  in  the  year  ended  December  31,  2015  when 
compared to the year ended December 31, 2014. We continue to maintain 
our  innovation  strategy  focusing  on  growing  our  existing  businesses, 
developing  opportunities  adjacent  or  closely  related  to  our  existing 
technical  and  manufacturing  capabilities,  and  investing  in  long-range 
opportunities in each of our market segments. We continue to work on 
new  products,  including  glass  substrates  for  high-performance  displays 
and  LCD  applications,  precision  glass  for  advanced  displays,  emission 

control  products  for  cars,  trucks,  and  off-road  vehicles,  products  that 
accelerate drug discovery and manufacturing and the optical fiber, cable 
and hardware and equipment that enable fiber-to-the-premises, and next 
generation data centers. In addition, we are focusing on wireless solutions 
for diverse venue applications, such as distributed antenna systems. We 
have also focused our research, development and engineering spending 
to support  the advancement of new product attributes for our Corning 
Gorilla  Glass  suite  of  products,  including  Gorilla  Glass®  in  automotive 
and  architectural  markets. We  will  continue  to  focus  on  adjacent  glass 
opportunities  which  leverage  existing  materials  or  manufacturing 
processes,  including  Corning®  Willow™  Glass,  our  ultra-slim  flexible 
glass  substrate  for  use  in  next-generation  consumer  electronic  and 
architectural applications.

2015 Results
The global economic headwinds, the continued softening in the television 
and consumer electronic device retail markets and the negative impact of 
the strengthening of the U.S. dollar negatively impacted Corning in 2015, 
resulting  in  lower  net  sales  and  net  income  when  compared  to  results 
in 2014.

Net sales in the year ended December 31, 2015 were $9,111 million, a decrease 
of  $604  million,  or  6%,  when  compared  to  the  year  ended  December 
31,  2014.  Sales  in  our  Optical  Communications  segment  increased  by 
$328 million, or 12%, but were more than offset by declines in our other 
segments. The increase in sales in the Optical Communications segment 
was due to an increase in volume in North America in both carrier network 
and enterprise network products and the impact of several acquisitions 
completed  in  2015. The  decrease  in  sales  of  $765  million,  or  20%,  in  the 
Display Technologies segment was the most significant segment decline, 
and  was  driven  by  the  depreciation  of  the  Japanese  yen  versus  the  U.S. 
dollar in the amount of $446 million and price declines in the low-teens in 
percentage terms, partially offset by a mid-single digit increase in volume.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

For  the  year  ended  December  31,  2015,  we  generated  net  income  of 
$1.3 billion, or $1.00 per share, compared to net income of $2.5 billion, or 
$1.73 per share, for 2014. When compared to last year, the decrease in net 
income was due to the following items (amounts presented after tax):

• The decrease in the unrealized gains from our foreign currency hedges 

related to translated earnings in the amount of $1,054 million;

• A  decrease  in  net  income  of  $301  million  in  the  Display Technologies 
segment, driven by price declines in the low-teens in percentage terms 
more than offsetting a mid-single digit percentage increase in volume, 
continued  softening  in  the  television  and  IT  retail  markets  and  the 
impact of the change in the fair value of the contingent consideration 
resulting  from  the  acquisition  of  Corning  Precision  Materials  in  the 
amount of $184 million;

• The increase of $81 million in our defined benefit pension plans mark-to-

market loss, driven by lower returns on our U.S. pension assets; and

• The  absence  of  a  gain  of  $38  million  recorded  in  2014  related  to  the 

settlement of an intellectual property dispute.

The  decrease  in  net  income  for  the  year  ended  December  31,  2015  was 
partially offset by the following items:

• The positive change in the amounts recorded related to tax law changes 

and valuation allowance adjustments of $204 million;

• An increase of $43 million in the Optical Communications segment, due 
to higher sales volume for both carrier and enterprise network products, 
the  favorable  impact  of  several  acquisitions  completed  this  year  and 
manufacturing efficiencies gained through cost reductions; and

Results of Operations

Selected highlights from our continuing operations follow (in millions):

• An increase in equity earnings of $33 million, driven by higher earnings 

at Dow Corning.

The translation impact of fluctuations in foreign currency exchange rates 
negatively affected Corning’s consolidated net income in the year ended 
December 31, 2015 in the amount of $294 million when compared to 2014. 
This impact was partially offset by the increase in the realized gain from 
our foreign currency translation hedges related to translated earnings of 
$186 million.

Corporate Outlook
In 2016, Corning expects its Display Technologies segment to experience 
continued moderate sequential LCD glass price declines and glass volume 
growth in the mid-single digit percentage year over year, in line with total 
glass  demand  growth.  We  anticipate  that  a  rise  in  global  demand  for 
Corning’s carrier and enterprise network products will drive an increase 
in sales of a mid-single digit percentage in our Optical Communications 
segment,  and  that  an  increase  in  Corning  Gorilla  Glass  and  advanced 
optics volume will drive sales growth in  the low-teens on a percentage 
basis  in  our  Specialty  Materials  segment.  We  expect  sales  in  our 
Environmental  Technologies  segment  to  be  down  slightly  for  the  year, 
driven  by  lower  year-over-year  demand  for  heavy-duty  diesel  products. 
And  we  expect  to  continue  the  execution  of  our  strategy  and  capital 
allocation framework begun in  the fourth quarter of 2015, under which 
we  plan  to  grow  and  sustain  our  leadership  position  in  the  markets  in 
which  we  operate  and  return  more  than  $10  billion  to  shareholders 
through 2019.

For the twelve months ended December 31, 2015, net sales decreased by 
$604 million, or 6%, when compared to the same period in 2014. Driving 
the decline in net sales are the following items:

• 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;

• 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.

An  increase  of  $328  million  in  the  Optical  Communications  segment 
slightly offset the decline in sales. The increase was 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  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.

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. 

Corning’s net sales in the year ended December 31, 2014 improved in all 
of  our  segments,  increasing  by  $1,896  million  to  $9,715  million,  when 
compared to the same period in 2013, driven by the following events:

• Display Technologies increased by $1.3 billion, due to the consolidation 
of Corning Precision Materials, which increased sales by $1.8 billion, and 
an increase in volume  that was slightly more  than 10% in percentage 
terms, partially offset by price declines in the mid-teens on a percentage 
basis and the negative impact of the Japanese yen versus the U.S. dollar 
exchange rate in the amount of $373 million;

• Optical  Communications 

increased  by  $326  million,  driven  by 
an  increase  in  sales  of  carrier  network  products  in  the  amount  of 
$254  million,  largely  due  to  growth  in  North  America  and  Europe, 
the  impact  of  a  full  year  of  sales  from  a  small  acquisition  and  the 
consolidation of an investment due to a change in control that occurred 
at  the  end  of  the  second  quarter  of  2013,  which  added  $53  million, 
and  an  increase  of  $72  million  in  enterprise  network  products. These 
increases were offset slightly by a $52 million decrease in optical fiber 
sales in China;

• An increase of $173 million in the Environmental Technologies segment, 
due mainly to an increase in demand for our heavy-duty diesel products, 
driven  by  new  governmental  regulations  in  Europe  and  China,  and 
increased  demand  for  Class  8  vehicles  in  North  America.  Automotive 
substrate  sales  were  also  strong,  increasing  9%,  due  to  increased 
demand in Europe and China;

• Specialty  Materials  improved  by  $35  million,  driven  by  an  increase  in 
sales of advanced optics products. Corning Gorilla Glass sales remained 
consistent  with  the  prior  year,  with  volume  increases  offset  by  an 
unfavorable shift in product mix and price declines; and 

• Life Sciences increased by $11 million, driven by growth in North America 

and China, up $12 million and $5 million, respectively.

In the year ended December 31, 2014, the translation impact of fluctuations 
in foreign currency exchange rates, primarily the Japanese yen, negatively 
affected Corning’s consolidated net sales in the amount of $347 million 
when compared to the same period in 2013. 

In 2015, 2014 and 2013, sales in international markets accounted for 70%, 
77% and 74%, 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.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Gross Margin
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 last year, 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  segment,  improvements  in 
manufacturing  performance  in  the  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. 

For 2014, gross margin dollars increased by $728 million when compared 
to 2013, driven largely by the consolidation of Corning Precision Materials, 
combined  with  an  increase  of  $102  million  in  the  Environmental 
Technologies segment from higher volume and improved manufacturing 
efficiencies. Gross  margin as a  percentage of net sales decreased when 
compared to the same period last year, due primarily to the impact of the 
depreciation of the Japanese yen versus the U.S. dollar in the amount of 
$333 million, price declines in the mid-teens in percentage terms in our 
Display Technologies segment, higher pension expense of approximately 
$50  million  and  the  impact  of  inventory  builds  in  2013  in  the  Optical 
Communications  and  Specialty  Materials  segments  that  did  not  repeat 
in 2014.

Selling, General and Administrative Expenses
In  the  twelve  months  ended  December  31,  2015,  selling,  general  and 
administrative  expenses  increased  by  $312  million  when  compared 
to  the  same  period  in  2014,  driven  primarily  by  an  increase  of  $133 
million  in  our  defined  benefit  pension  plans  mark-to-market  loss,  the 
absence  of  the  positive  impact  of  a  contingent  consideration  fair  value 
adjustment of $249 million recorded in 2014 and an increase in spending 
in  the  Optical  Communications  segment  driven  by  several  acquisitions 
completed in 2015. Offsetting these increases somewhat were a decrease 
in  variable  compensation,  lower  spending  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. When compared 
to the same period last year, as a percentage of net sales, selling, general 
and administrative expenses increased driven by lower net sales in 2015. 

Selling, general and administrative expenses for the year ended December 
31, 2014 increased by $85 million when compared to 2013. The increase was 
largely driven by the consolidation of Corning Precision Materials, which 
added $90 million, an increase in pension expense of approximately $27 
million, an increase of $38 million in share-based and performance-based 
compensation  expenses  and  an  increase  of  approximately  $90  million 
in  acquisition-related  costs,  including  $72  million  of  post-combination 
compensation  expense,  offset  somewhat  by  the  positive  impact  of  a 
contingent  consideration  fair  value  adjustment  of  $249  million.  As  a 
percentage  of  net  sales,  selling,  general  and  administrative  expenses 
were 12%, considerably lower than the same period in 2013, largely due to 
the contingent consideration fair value adjustment more than offsetting 
the  increase  in  Selling,  general  and  administrative  expenses  resulting 
from the acquisition of Samsung Corning Precision Materials.

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
For  the  year  ended  December  31,  2015,  research,  development  and 
engineering  expenses  decreased  by  $46  million  when  compared  to  the 
same  period  last  year,  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.

For  the  year  ended  December  31,  2014,  research,  development  and 
engineering  expenses  increased  by  $105  million  when  compared  to  the 
same  period  last  year,  driven  by  the  consolidation  of  Corning  Precision 
Materials,  which  added  $69  million,  an  increase  of  approximately 
$30  million  in  new  business  development  spending  and  $20  million 
of  additional  pension  expense.  We  continue  to  focus  on  new  product 
development  in  areas  such  as  glass  substrates  for  high  performance 
displays  in  our  Display  Technologies  segment,  wireless  solutions  for 
diverse venue applications in the Optical Communications segment and 
advancement  of  new  product  attributes  for  our  Corning  Gorilla  Glass 
suite  of  products  in  our  Specialty  Materials  segment.  As  a  percentage 
of  net  sales,  research,  development  and  engineering  expenses  declined 
slightly, from 9% in 2013 to 8% in 2014, reflecting cost control measures 
implemented in 2014.

Restructuring, Impairment, and Other Charges 
Corning  recorded  restructuring,  impairment,  and  other  charges  and 
credits in 2014 and 2013, 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:

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, asset disposals and write-offs, and exit costs for 
restructuring  activities  with  total  cash  expenditures  of  approximately 
$39 million. Annualized savings from  these actions are estimated  to be 
approximately $94 million and will be reflected largely in selling, general 
and administrative expenses.

2013 Activity

To better align our 2014 cost position in several of our businesses, Corning 
implemented a global restructuring plan within several of our segments 
in  the  fourth  quarter  of  2013,  consisting  of  workforce  reductions,  asset 
disposals  and  write-offs,  and  exit  costs.  We  recorded  charges  of  $67 
million, before tax, associated with these actions. Cash expenditures were 
approximately $35 million.

in 2015 compared to $13 million gain in 2014); and 

–  Lower  volume  and  unfavorable  movements 

in 

foreign 

exchange rates. 

• A significant increase in equity earnings from the polysilicon business 
in  the  amount  of  $522  million,  driven  by  the  absence  of  the 
$465 million charge for the abandonment of a polycrystalline silicon 
plant expansion recorded in 2014 and an increase in Corning’s share of 
settlements of long-term sales agreements in the amount of $40 million 
($49 million in  the first quarter of 2015 compared  to $9 million in  the 
first quarter of 2014), partially offset by lower volume.

2014 vs. 2013

Equity earnings from Dow Corning increased by $56 million in the twelve 
months ended December 31, 2014, when compared to the same period in 
2013, driven by the following items:

• An increase in equity earnings of $487 million in the silicones segment, 
driven by the gain resulting from the reduction of the Implant Liability 
in the amount of $393 million, favorable tax adjustments in the amount 
of  $46  million  and  a  decrease  in  tax  expense,  offset  somewhat  by  a 
$5  million  decrease  in  the  amount  of  gains  recorded  on  the  mark-to-
market of a derivative instrument; and

• A decrease in equity earnings of $431 million in the polysilicon segment, 
driven by Corning’s share of Dow Corning’s charge for the abandonment 
of  a  polycrystalline  silicon  plant  expansion  in  the  amount  of  $465 
million,  offset  slightly  by  higher  volume,  the  absence  of  $11  million  in 
restructuring  charges  incurred  in  the  first  half  of  2013,  a  gain  in  the 
amount of $6 million related to energy tax credits and the settlement of 
a long-term sales agreement in the first quarter of 2014 in the amount 
of $9 million.

Silicones

Polysilicon (Hemlock Semiconductor Group)

Total Dow Corning

In  May  1995,  Dow  Corning  filed  for  bankruptcy  protection  to  address 
pending  and  claimed  liabilities  arising  from  many  thousands  of  breast 
implant  product  lawsuits.  On  June  1,  2004,  Dow  Corning  emerged  from 
Chapter  11  with  a  Plan  of  Reorganization  (the  “Plan”)  which  provided 
for  the  settlement  or  other  resolution  of  implant  claims. The  Plan  also 
includes  releases  for  Corning  and  Dow  Chemical  as  shareholders  in 
exchange for contributions to the Plan.

Under the terms of the Plan, Dow Corning has established and is funding 
a  Settlement Trust  and  a  Litigation  Facility  to  provide  a  means  for  tort 
claimants  to  settle  or  litigate  their  claims.  Inclusive  of  insurance,  Dow 
Corning has paid approximately $1.8 billion to the Settlement Trust. As of 
December 31, 2015, Dow Corning had recorded a reserve for breast implant 
litigation  of  $291  million.  See  Note  7  (Investments)  to  the  Consolidated 
Financial Statements and Part II – Item 3. Legal Proceedings for additional 
detail. 

On  December  11,  2015,  Corning  announced  its  intention  to  exchange  its 
50%  equity  interest  in  Dow  Corning  Corporation  for  100%  of  the  stock 
of a newly formed entity that will become a wholly-owned subsidiary of 
Corning. The newly formed entity will hold approximately 40% ownership 
in Hemlock Semiconductor Group and approximately $4.8 billion in cash. 
Upon  completion  of  this  strategic  realignment,  which  is  expected  to 
close during the first half of 2016, Dow Chemical, an equal owner of Dow 
Corning  with  Corning  since  1943,  will  assume  100%  ownership  of  Dow 
Corning. 

2015 vs. 2014

Equity earnings from Dow Corning increased by $29 million in the twelve 
months ended December 31, 2015, when compared to the same period in 
2014, driven by the following items:

• A decrease in equity earnings from the silicones business of $493 million, 

driven by the following items:

–  The absence of the gain resulting from the reduction of the Implant 

Liability in the amount of $393 million;

–  The  absence  of  $46  million  of  favorable  tax  adjustments  recorded 

in 2014;

The  gross  notional  value  outstanding  for  our  foreign  currency  hedges 
related  to  translated  earnings  at  December  31,  2015  is  $11.9  billion,  and 
is  comprised  of  the  following:  1)  Japanese  yen-denominated  hedges  - 

$8.3 billion; 2) South Korean won-denominated hedges - $3.3 billion; and 
3) euro-denominated hedges - $345 million.

Income Before Income Taxes
The translation impact of fluctuations in foreign currency exchange rates 
negatively  affected  Corning’s  Income  before  income  taxes  in  the  year 
ended December 31, 2015 in the amount of $388 million when compared 

to  2014.  This  impact  was  partially  offset  by  the  increase  in  the  realized 
gain  from  our  foreign  currency  translation  hedges  related  to  translated 
earnings of $379 million.

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

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

• The impact of equity in earnings of nonconsolidated affiliates reported in

• $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 Germany and Japan deferred tax assets which is partially 
offset with tax expense from U.S. state and China deferred tax allowances 
increases.

The effective income tax rate for 2014 differed from the U.S. statutory rate 
of 35% primarily due to the following items:

• Rate  differences  on  income  (loss)  of  consolidated  foreign  companies,

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Partially offsetting the benefits above is a $177 million charge attributable 
to a change in judgment on the realizability of certain foreign deferred tax 
assets in Germany and Japan. 

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  or  amount  required  to  utilize 
these assets before  they expire. The amount of U.S. and foreign deferred 
tax assets that have remaining valuation allowances at December 31, 2015 
and 2014 was $238 million and $298 million, respectively.

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  that may impact our ability or intent  to keep our foreign earnings 
and  cash  indefinitely  reinvested  include  significant  U.S.  acquisitions, 
stock  repurchases,  shareholder  dividends,  changes  in  tax  laws,  derivative 

contract settlements or the development of tax planning ideas that allow 
us to repatriate earnings at minimal or no tax cost, and/or a change in our 
circumstances or economic conditions  that negatively impact our ability 
to  borrow  or  otherwise  fund  U.S.  needs  from  existing  U.S.  sources.  As  of 
December  31,  2015,  taxes  have  not  been  provided  on  approximately  $11 
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.

Our  foreign  subsidiary  in  Taiwan  operates  under  various  tax  holiday 
arrangements. The nature and extent of such arrangements vary, and the 
benefits of such arrangements phase out through 2018. The impact of the 
tax holidays on our effective rate is a reduction in the rate of 0.5, 0.4 and 1.2 
percentage points for 2015, 2014 and 2013, respectively.

While we expect the amount of unrecognized tax benefits to change in the 
next 12 months, we do not expect the change to have a significant impact 
on the results of operations or our financial position.

for further details regarding income tax matters.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

2015 vs. 2014

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,  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. 

2014 vs. 2013

For  the year ended December 31, 2014, comprehensive income decreased 
by $528 million when compared to the same period in 2013, driven by an 
increase  in  unamortized  losses  for  postretirement  benefit  plans  and  the 
negative impact of the change in foreign currency translation adjustments, 
offset by an increase of $511 million in net income attributable to Corning 
Incorporated. 

The  increase  in  unamortized  losses  for  postretirement  benefit  plans  in 
the  amount  of  $673  million  is  driven  mainly  by  changes  to  the  discount 

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 
management rate which is closely aligned to our foreign currency hedges. 
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.

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  foreign  currency  hedges 

rate  and  mortality  assumptions  used  to  value  Corning’s  U.S.  pension 
and  postretirement  medical  and  life  benefit  plan  (“OPEB”)  obligations 
and  the  benefit  plan  obligations  of  our  equity  affiliate  Dow  Corning 
at  December  31,  2014.  Corning  and  Dow  Corning  adopted  the  Society  of 
Actuaries  mortality  table  RP-2014  published  in  October  2014,  along  with 
an updated improvement scale, and the discount rate for our U.S. benefit 
plans  decreased  between  75  and  100  basis  points.  At  December  31,  2014, 
the decrease in discount rates and the change in the mortality assumption 
for our U.S. plans led  to an actuarial after-tax loss of approximately $281 
million  versus  a  gain  in  2013  of  $392  million.  The  loss  of  $281  million 
occurring in 2014 included the impact to our U.S. pension and OPEB plans 
from the mortality table change in the amount of $88 million, the impact of 
$89 million from changes in other actuarial assumptions and $124 million 
from  our  equity  affiliate  Dow  Corning,  offset  by  reclassifications  to  the 
income statement of $20 million after-tax related to U.S. non-qualified and 
international pension plans. Because the actuarial loss for our U.S qualified 
pension plan did not fall outside of the corridor, which is defined as equal 
to 10% of the greater of the benefit obligation or the market-related value 
of plan assets at the beginning of the year, it was recorded in accumulated 
other comprehensive income (“AOCI”) and did not impact net income for 
the year ended December 31, 2014. 

The  increase  in  the  loss  on  foreign  currency  translation  adjustments  for 
the  year  ended  December  31,  2014  in  the  amount  of  $391  million  was 
driven by the following items: 1) the increase in the loss in the translation 
of Corning’s consolidated subsidiaries in the amount of $65 million, which 
resulted primarily from the depreciation of the Japanese yen to U.S. dollar 
translation rate during 2014; 2) the increase in the loss in the translation of 
Corning’s equity method investments in the amount of $190 million; and 
3) the reclassification of a gain to net income in the amount of $136 million 
related to the acquisition of Samsung Corning Precision Materials.

Management’s  discussion  and  analysis  on  our  reportable  segments  has

Corning’s core net sales in the year ended December 31, 2014 improved in 
all of our segments, increasing by $2,175 million to $9,955 million, when 
compared to the same period in 2013. Driving the growth in core net sales 
are the following items:

• Display Technologies increased by $1,585 million, due to the consolidation 
of  Corning  Precision  Materials  and  an  increase  in  volume  that  was 
slightly more than 10% in percentage terms, offset somewhat by price 
declines in the mid-teens;

• Optical  Communications  increased  by  $326  million,  driven  by  an 
increase in sales of carrier network products in the amount of $254 million, 
largely  due  to  growth  in  North  America  and  Europe,  the  impact  of  a 
full year of sales from a small acquisition and  the consolidation of an 
investment due to a change in control that occurred at the end of the 
second  quarter  of  2013,  which  added  $53  million,  and  an  increase  of 
$72 million in enterprise network products. These increases were offset 
slightly by a $52 million decrease in optical fiber sales in China;

• An increase of $173 million in the Environmental Technologies segment, 
due mainly to an increase in demand for our heavy duty diesel products, 
driven  by  new  governmental  regulations  in  Europe  and  China,  and 
increased  demand  for  Class  8  vehicles  in  North  America.  Automotive 
substrate sales were also strong, increasing 9%, on increased demand in 
Europe and China;

• Specialty  Materials  improved  by  $35  million,  driven  by  an  increase  in 
sales of advanced optics products. Corning Gorilla Glass sales remained 
consistent  with  the  prior  year,  with  volume  increases  offset  by  an 
unfavorable shift in product mix and price declines; and 

• Life Sciences increased by $11 million, driven by growth in North America 

and China, up $12 million and $5 million, respectively.

The  translation  impact  from  movements  in  foreign  currency  exchange 
rates  in  the  years  ended  December  31,  2015  and  2014,  excluding  the 
Japanese yen and South Korean won, negatively affected core net sales in 
the amount of $215 million and $68 million, respectively, when compared 
to the prior years.

In all segments except Display Technologies, core net sales are consistent 
with  GAAP  net  sales.  Because  a  significant  portion  of  revenues 
and  manufacturing  costs  in  the  Display  Technologies  segment  are 
denominated  in  Japanese  yen,  this  segment  is  adjusted  to  remove  the 
impact 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 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 $155 million to $9.8 billion in the year ended 
December 31, 2015 when compared to the same period in 2014. Driving the 
decline in core net sales are the following items:

• A decrease of $318 million in the Display Technologies segment, driven 
by  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;

in 

• A  decrease 

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.

An  increase  of  $328  million  in  the  Optical  Communications  segment 
slightly offset the decline in sales. The increase was 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 
increased, 
products  sales.  Sales  of  carrier  network  products  also 
up  $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.

2015 vs. 2014

Core equity earnings from Dow Corning decreased by $42 million, or 15%, 
in the year ended December 31, 2015, when compared to the same period 
last  year,  due  to  lower  volume  and  unfavorable  movements  in  foreign 
exchange rates and the devaluation of the Chinese yuan.

2014 vs. 2013

Core equity earnings from Dow Corning increased in the twelve months 
ended  December  31,  2014,  when  compared  to  the  same  period  in  2013, 
driven by higher earnings in both the silicones and polysilicon segments. 
Driving  the  increase  was  a  decrease  in  tax  expense  in  the  silicones 
segment and higher volume and improved manufacturing performance 
in the polysilicon segment.

Core Earnings

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.

2014 vs. 2013

When  compared  to  the  same  period  in  the  prior  year,  core  earnings 
increased in the twelve months ended December 31, 2014 by $367 million, 
or  22%,  to  $2,023  million,  driven  by  the  following  items  (amounts 
presented after-tax):

• The impact of the consolidation of Corning Precision Materials and the 
resulting cost reductions and efficiencies gained through synergies; 

• An  increase  in  core  equity  earnings  from  Dow  Corning,  driven  by  a 
decrease  in  tax  expense,  improved  manufacturing  efficiency  and  an 
increase in volume; 

• An increase of $58 million in the Environmental Technologies segment, 
driven by an increase in demand for our diesel products and improved 
manufacturing efficiency; and

• An  increase  of  $34  million  in  the  Optical  Communications  segment, 
driven by higher sales of carrier network and enterprise network products.

The increase in core earnings for the year ended December 31, 2014 was 
offset somewhat by price declines in the mid-teens in percentage terms 
outpacing an increase in volume slightly higher than 10% in our Display 
Technologies segment.

Included  in  core  earnings  for  the  years  ended  December 31,  2015,  2014 
and 2013 is net periodic pension expense in the amount of $62 million, 
$74  million  and  $37  million,  respectively,  which  excludes  the  annual 
pension mark-to-market adjustments. In the years ended December 31, 
2015,  2014  and  2013,  the  mark-to-market  adjustments  were  a  pre-tax 
loss of $165 million, a pre-tax loss of $29 million and a pre-tax gain of 
$30 million, respectively. Refer to Note 13 (Employee Retirement Plans) to 
the Consolidated Financial Statements for additional information.

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  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.

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.

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: Following the acquisition of Samsung Corning Precision Materials and 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)  Foreign currency hedges related to translated earnings: We have excluded the impact of the gains and losses of our foreign currency hedges related 

to translated earnings 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.

31

CORNING INCORPORATED - 2015 Annual Report 
 
Management’s Discussion and Analysis of Financial Condition and Results of Operations

(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. In 2013, we excluded the 
operating results of Dow Corning’s consolidated subsidiary Hemlock Semiconductor, a producer of polycrystalline silicon, to remove the impact of 
the severe unpredictability and instability in the polysilicon market. 

(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 change in control of equity investment: Gain as a result of certain changes to the shareholder agreement of an equity company, resulting in 

Corning having a controlling interest that requires consolidation of this investment.

Reportable Segments

Our reportable segments are as follows:

• Display Technologies – manufactures glass substrates for flat panel liquid 

crystal displays.

• Optical Communications – manufactures carrier network and enterprise 

network components for the telecommunications industry.

• Environmental  Technologies  –  manufactures  ceramic  substrates  and 

filters for automotive and diesel 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 to provide 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,  which  consists  of  a  pharmaceutical  glass  business  and  a  glass 
tubing  business  used  in  the  pharmaceutical  packaging  industry.  This 
segment also includes Corning Precision Materials’ non-LCD business and 
new  product  lines  and  development  projects  such  as  laser  technologies, 
advanced flow reactors and adjacency businesses in pursuit of thin, strong 
glass,  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  our  reportable 
segments differently than we would for stand-alone financial information 
prepared in accordance with U.S. GAAP. The Display Technologies, Optical 
Communications, Environmental Technologies, Specialty Materials and Life 
Sciences  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  with  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 the 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

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. 

income 

Net 
in  the  Display  Technologies  segment  decreased  by 
$301  million,  or  22%,  in  the  year  ended  December  31,  2015,  when 
compared to the same period last year. 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.

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

• 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 foreign currency hedges related to translated 
earnings in the amount of $126 million. 

last  year,  the 

2014 vs. 2013
When  compared  to  the  same  period 
increase  of 
$1,306  million  in  net  sales  in  the  year  ended  December  31,  2014,  was 
due  to  the  acquisition  of  the  remaining  equity  interests  of  our  affiliate 
Samsung Corning Precision Materials, and the consolidation of this entity, 
which added $1.8 billion in net sales. This impact was somewhat offset 
by  price  declines  in  the  mid-teens  in  percentage  terms,  which  more 
than  offset  an  increase  in  volume  that  was  slightly  more  than  10%  in 
percentage  terms,  and  the  depreciation  of  the  Japanese  yen  versus  the 
U.S. dollar, which adversely impacted net sales by $373 million.

Net income in the Display Technologies segment increased by $103 million, 
or 8%, in the year ended December 31, 2014, when compared to the same 
period last year. This increase was driven by the following items:

• The  impact  of  the  acquisition  of  Corning  Precision  Materials  and  the 

resulting cost reductions gained through synergies; 

• The  fair  value  adjustment  of  the  contingent  consideration  resulting 
from  the  acquisition  of  Corning  Precision  Materials  in  the  amount  of 
$194 million; and

• Improvements in manufacturing efficiency of $79 million;

• Improvements in manufacturing efficiency of $46 million. 

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

$73 million and $37 million, respectively; 

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

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

more than offset the increase in volume;

33

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

• The  absence  of  the  $67  million  gain  from  our  yen-denominated  cash 

flow hedging program; 

• The increase in transaction and acquisition-related costs related to the 
acquisition of Corning Precision Materials in the amounts of $73 million 
and $29 million, respectively; and

• An  increase  of  $34  million  in  restructuring,  impairment  and  other 

charges.

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.

2014 vs. 2013
When compared to the same period last year, the increase in core net sales 
of $1,585 million, or 63%, in the year ended December 31, 2014, was due to 
the acquisition of the remaining equity interests of our affiliate Samsung 
Corning  Precision  Materials,  and  the  consolidation  of  this  entity,  which 
added $1.9 billion in net sales. This impact was somewhat offset by price 
declines  in  the  mid-teens  in  percentage  terms,  which  more  than  offset 
an  increase  in  volume  that  was  slightly  more  than  10%  in  percentage 
terms.  Core  earnings  in  the  Display Technologies  segment  increased  by 
$110 million, or 10%, in the year ended December 31, 2014, when compared 
to  the  same  period  last  year.  The  increase  was  driven  by  the  positive 
impact of the acquisition of Corning Precision Materials and the resulting 
cost reductions gained through synergies, coupled with improvements in 
manufacturing efficiency of $46 million, partially offset by the impact of 
price declines in the mid-teens in percentage terms that more than offset 
the increase in volume. 

Other Information

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  2015,  three  customers  of  the  Display 
Technologies segment, which individually accounted for more than 10% 
of  segment  net  sales,  accounted  for  a  combined  62%  of  total  segment 
sales. In 2014, three customers of the Display Technologies segment, which 
individually accounted for more than 10% of segment net sales, accounted 
for a combined 61% of total segment sales. In 2013, four customers of the 
Display  Technologies  segment,  which  individually  accounted  for  more 
than 10% of segment net sales, accounted for a combined 94% of  total 
segment sales. Our customers face the same global economic dynamics 
as we do in this market. Our near-term sales and profitability would be 
impacted if any of these significant customers were unable to continue 
to purchase our products.

In addition, prior to consolidation, Samsung Corning Precision Materials’ 
sales were concentrated across a small number of its customers. In 2013, 
sales  to  two  LCD  panel  makers  located  in  South  Korea  accounted  for 
approximately 93% of Samsung Corning Precision Materials sales.

Corning has invested to expand capacity to meet the projected demand 
for LCD glass substrates. In 2015, 2014 and 2013, capital spending in this 
segment was $594 million, $492 million and $350 million, respectively. We 
expect capital spending for 2016 to be approximately $600 million.

2016 Outlook:

In  the  first  quarter  of  2016,  Corning  anticipates  that  panel  maker 
utilization  will  continue  to  decline,  which  will  reduce  inventory  levels 
in  the  supply  chain.  As  a  result,  the  overall  glass  market  and  Corning’s 
LCD  glass  volume  are  expected  to  decline  by  a  mid-to-high  single-digit 
percentage  sequentially.  Corning’s  LCD  glass  price  decline  is  expected 
to  be  moderate,  achieving  what  will  be  one  of  the  lowest  first-quarter 
declines in five years.

For  the full year, Corning expects  moderate sequential price declines  to 
continue, and for its glass volume to grow by a mid-single-digit percentage 
year over year, in line with  total glass demand growth. Corning expects 
global television unit sales will grow by a low single-digit percentage, and 
the average screen size will increase by at least 1.5 inches. The company 
expects  panel  maker  utilization  to  increase  as  the  year  progresses,  and 
retail LCD glass area demand to be up by a high single-digit percentage 
in 2016.

As Reported

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.

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.

2014 vs. 2013
In the twelve months ended December 31, 2014, net sales of the Optical 
Communications  segment  increased  by  $326  million,  or  14%,  when 
compared  to  the same period in 2013, driven by a $254 million increase 
in sales of our carrier network products. Specifically, the following items 
impacted  sales  within  the  carrier  network  products  group  in  the  year 
ended December 31, 2014:

• Higher sales of cable and hardware and equipment products primarily 
used  in  fiber-to-the-home  solutions  in  North  America  and  Europe,  up 
$113 million and $46 million, respectively; 

• The  impact  of  a  full  year  of  sales  from  a  small  acquisition  and  the 
consolidation  of  an  investment  due  to  a  change  in  control  which 
occurred  at  the  end  of  the  second  quarter  of  2013,  which  added 
approximately $53 million; and

• An increase of $11 million in sales of optical fiber, driven by higher sales 
in North America and Europe, partially offset by a decrease in China.

Sales of enterprise network products also increased in the twelve months 
ended  December  31,  2014,  up  $72  million,  when  compared  to  the  same 
period in 2013, due  to strong sales in all regions of  the world, led by an 
increase  in  sales  of  data  center  and  LAN  products  in  Europe  and  North 
America,  up  $21  million  and  $20  million,  respectively,  and  an  increase 
of  $16  million  in  wireless  products  sales.  The  translation  impact  from 
movements  in  foreign  currency  exchange  rates  in  2014  negatively 
impacted Optical Communications net sales in the amount of $64 million, 
when compared to the same period in 2013.

Net income increased by $5 million, or 3%, in 2014, when compared to 2013. 
The significant increase in volume for carrier network products in North 
America  and  Europe  and  an  increase  in  worldwide  enterprise  network 
product volume were somewhat offset by price declines in fiber and cable 
products, $17 million of additional operating expenses driven by two small 
acquisitions  and  the  absence  of  the  inventory  build  we  experienced  in 
the first half of 2013. An increase in restructuring charges of $9 million, 
an increase of $22 million in the amount of the pension mark-to-market 
adjustment and the absence of the $11 million gain on change in control 
of  an  equity  company  that  occurred  in  the  second  quarter  of  2013  also 
negatively impacted the results of this segment. 

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, 2014 when compared to the same period in 2013.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Core Performance

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. 

2014 vs. 2013
Core earnings in the twelve months ended December 31, 2014 increased 
by $34 million, or 18%, when compared  to 2013. The significant increase 
in  volume  for  carrier  network  products  in  North  America  and  Europe 
and an increase in worldwide enterprise network product volume were 
somewhat offset by price declines in fiber and cable products, $17 million 
of additional operating expenses driven by two small acquisitions and the 
absence of the inventory build we experienced in the first half of 2013. 

The Optical Communications segment has a concentrated customer base. 
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  years  ended  December  31,  2014  and 
2013,  one  customer,  which  individually  accounted  for  more  than  10% 
of  segment  net  sales,  accounted  for  11%  and  10%,  respectively,  of  total 
segment net sales.

2016 Outlook: 

Corning expects sales in the first quarter of 2016 to increase in the low-to-
mid-single digit percentage range over its sales in the comparable period 
a year ago. For the full year, the company expects sales to increase by a 
mid-single-digit percentage and exceed the goal of two times the growth 
rate of industry capital expenditures.

As Reported

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 last year, 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.

2014 vs. 2013
In the twelve months ended December 31, 2014, net sales of this segment 
increased by $173 million, or 19%, when compared to the same period in 
2013, driven by higher sales across all product lines. Driving the increase 
was higher demand for our heavy-duty diesel products propelled by new 
governmental regulations in Europe and China and increased demand for 
Class 8 vehicles in North America. Sales of light-duty diesel products also 
improved due to higher volume in Europe. Automotive substrate product 
sales increased due to higher demand in Europe and China.

When compared to the same period last year, net income in the twelve 
months ended December 31, 2014 improved significantly, up $51 million, 
or 40%, driven by improvements in manufacturing efficiency and strong 
volume gains across both automotive and diesel product lines. Improving 
market  conditions  for  heavy-duty  diesel  products  in  Europe,  China  and 
North America and higher European sales of light-duty diesel products, 
combined  with  an  increase  in  automotive  vehicle  builds,  drove  the 
increase. Higher costs associated with facility expansion projects and an 
increase in the pension mark-to-market adjustment somewhat offset the 
increase in net income.

The  translation  impact  from  movements  in  foreign  currency  exchange 
rates did not significantly impact sales or net income of this segment in 
the  year  ended  December  31,  2014  when  compared  to  the  same  period 
in 2013.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Core Performance

2015 vs. 2014
Core  earnings  declined  by  $22  million,  or  12%,  in  the  year  ended 
December 31, 2015, when compared  to  the same period last year, 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.

2014 vs. 2013
When compared to the same period last year, core earnings in the twelve 
months ended December 31, 2014 increased by $58 million, or 46%, driven 
by improvements in  manufacturing efficiency and strong volume gains 
across  both  automotive  and  diesel  product  lines.  Improving  market 
conditions  for  heavy-duty  diesel  products  in  Europe,  China  and  North 
America and higher European sales of light-duty diesel products, combined 
with an increase in automotive vehicle builds, drove the increase. Higher 
costs  associated  with  facility  expansion  projects  somewhat  offset  the 
increase in net income.

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 
2015,  2014  and  2013,  net  sales  to  three  customers,  which  individually 
accounted for more than 10% of segment sales, accounted for 86%, 88% 
and  87%,  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.

2016 Outlook: 

The North American heavy-duty truck market is down after several years 
of robust growth. As a result, first-quarter sales are expected to decline 
by approximately 10%, compared with the same period last year. The full-
year outlook is for sales to decline by a low single-digit percentage.

As Reported

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 last year, 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.

2014 vs. 2013
Net sales for the twelve months ended December 31, 2014 in the Specialty 
Materials  segment  increased  by  $35  million,  or  3%,  when  compared  to 
the  same  period  in  2013,  driven  by  higher  sales  of  our  advanced  optics 
and commercial optics products. Although Corning Gorilla Glass volume 
increased by 23%, net sales remained consistent with the prior year, driven 
by  an  unfavorable  shift  in  product  mix  and  price  declines.  Additionally, 
although volume increased in 2014 when compared to 2013, the growth 
did not meet our expectations due to the flat market for tablets. 

When compared to the same period last year, the decrease in net income 
of $43 million, or 24%, for the twelve months ended December 31, 2014 was 
driven by the absence of the inventory build we experienced in the first 
half of 2013, the write-off of a trade receivable balance in the amount of 
$8 million and price declines for Corning Gorilla Glass. Partially offsetting 
the decrease was an increase in volume for both Corning Gorilla Glass and 
advanced optics products and the impact of costs reductions as a result 
of restructuring actions.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

The  translation  impact  from  movements  in  foreign  currency  exchange 
rates did not significantly impact sales or net income of this segment in 
the  year  ended  December  31,  2014  when  compared  to  the  same  period 
in 2013.

Core Performance

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.

2014 vs. 2013
When compared to the same period last year, the decrease in core earnings 
of $34 million, or 18%, in the twelve months ended December 31, 2014 was 

driven by the absence of the inventory build we experienced in the first 
half of 2013, price declines for Corning Gorilla Glass and higher production 
costs. Partially offsetting the decrease was an increase in volume for both 
Corning  Gorilla  Glass  and  advanced  optics  products  and  the  impact  of 
costs reductions as a result of restructuring actions. 

For  2015,  2014  and  2013,  three  customers  of  the  Specialty  Materials 
segment,  which  individually  accounted  for  more  than  10%  of  segment 
sales, accounted for 56%, 51% and 47%, respectively, of total segment sales. 

2016 Outlook: 

First-quarter sales are expected  to decline year over year  by a mid-teen 
percentage. For 2016, the Company estimates annual sales will grow by 
a  low-teen  percentage  when  compared  to  2015.  The  variable  timing  of 
mobile device product launches drives Corning Gorilla Glass demand and 
is expected to cause significant swings in quarterly results.

Net sales for the year ended December 31, 2015 decreased by $41 million, 
or 5%, when compared to the same period last year, 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 last year, with the negative impact from movements in 
foreign exchange rates in the amount of $14 million more than offsetting 
improvements in manufacturing efficiency.

2014 vs. 2013
Net sales for the year ended December 31, 2014 increased by $11 million 
when  compared  to  the  same  period  in  the  prior  year.  Higher  sales  in 
North  America  and  China,  up  $12  million  and  $5  million,  respectively, 
were  offset  slightly  by  lower  sales  in  Australia.  Net  income  remained 
relatively consistent when compared  to  the same period in 2013, driven 
by less favorable product mix and higher operating expenses which more 
than offset higher volume and lower acquisition-related costs due to the 
completion of the integration of Discovery Labware business. 

The  translation  impact  from  movements  in  foreign  currency  exchange 
rates did not significantly impact sales or net income of this segment in 
the  year  ended  December  31,  2014  when  compared  to  the  same  period 
in 2013.

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 
last year, with the negative impact from movements in foreign exchange 
rates more than offsetting improvements in manufacturing efficiency. 

2014 vs. 2013
Core  earnings  decreased  by  $6  million  in  the  year  ended  December  31, 
2014, when compared to the same period in 2013, driven by less favorable 
product mix, offset somewhat by higher volume. 

For  2015,  2014  and  2013,  two  customers  in  the  Life  Sciences  segment, 
which  individually  accounted  for  more  than  10%  of  total  segment  net 
sales, collectively accounted for 46%, 45% and 44%, respectively, of total 
segment sales.

2016 Outlook: 

First-quarter  sales  are  expected  to  increase  by  a  low  single-digit 
percentage, compared with last year. For the full year, sales are anticipated 
to  grow  faster  than  the  market,  which  is  expected  to  be  up  by  a  low 
single-digit percentage.

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, which consists of a pharmaceutical glass business and a glass 
tubing  business  used  in  the  pharmaceutical  packaging  industry.  This 

segment also includes Corning Precision Materials’ non-LCD business and 
new product lines and development projects such as laser technologies, 
advanced  flow  reactors  and  adjacency  businesses  in  pursuit  of  thin, 
strong  glass,  as  well  as  certain  corporate  investments  such  as  Eurokera 
and Keraglass equity affiliates.

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 businesses. 

2014 vs. 2013
The increase in net sales of this segment in the year ended December 31, 
2014  reflects  the  consolidation  of  the  Corning  Precision  Materials’  non-
LCD business as a result of  the acquisition. The increase in  the  net loss 
of this segment reflects higher spending for development projects which 
were not part of the segment in the year ended December 31, 2013. 

Liquidity and Capital Resources

Financing and Capital Structure
The following items impacted Corning’s financing and capital structure 
during 2015, 2014 and 2013:

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.

2014

• In  the  third  quarter  of  2014,  we  amended  and  restated  our 
existing  revolving  credit  facility.  The  amended  facility  provides  a 
$2  billion  unsecured  multi-currency  line  of  credit  and  expires  on 
September 30, 2019. At December 31, 2015,  there were no outstanding 
amounts under this credit facility. The facility includes affirmative and 
negative covenants that Corning must comply with, including a leverage 
(debt  to  capital  ratio)  financial  covenant.  As  of  December  31,  2015,  we 
were in compliance with all of the covenants.

2013

• In the first quarter of 2013, we amended and restated our then-existing 
revolving credit facility. The 2013 amended facility provided a $1 billion 
unsecured  multi-currency  line  of  credit  that  would  have  expired  in 
March  2018. This  facility  was  amended  and  restated  by  the  $2  billion 
facility entered into in the third quarter of 2014.

• In  the  first  quarter  of  2013,  Corning  repaid  the  aggregate  principal 
amount  and  accrued  interest  outstanding  on  the  credit  facility 
entered  into  in  the  second  quarter  of  2011  that  allowed  Corning  to 
borrow  up  to  Chinese  renminbi  (RMB)  4  billion.  The  total  amount 
repaid  was  approximately  $500  million.  Upon  repayment,  this  facility 
was terminated.

• In the second quarter of 2013, the Company established a commercial 
paper program on a private placement basis, pursuant to which we may 
issue short-term, unsecured commercial paper notes up to a maximum 
aggregate principal amount outstanding at any time of $1 billion. Under 
this program, the Company may issue the notes from time to time and 
will  use  the  proceeds  for  general  corporate  purposes.  The  maturities 
of  the  notes  will  vary,  but  may  not  exceed  390  days  from  the  date  of 
issue. The interest rates will vary based on market conditions and  the 
ratings  assigned  to  the  notes  by  credit  rating  agencies  at  the  time  of 
issuance. The Company’s revolving credit facility is available to support 
obligations under the commercial paper program, if needed.

• In  the  fourth  quarter  of  2013,  we  issued  $250  million  of  3.70% 
senior  unsecured  notes  that  mature  on  November  15,  2023.  The 
net  proceeds  of  approximately  $248  million  were  used  for  general 
corporate purposes.

• In the fourth quarter of 2013, we recorded a financing obligation in the 
approximate  amount  of  $230  million  for  a  new  LCD  glass  substrate 
facility in China.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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. This 
increase marks the fifth dividend increase since October 2011. The Board 
previously  increased  the  quarterly  dividend  20%,  from  $0.10  to  $0.12, 
on  December  3,  2014.  The  Company  paid  four  quarterly  dividends  of 
$0.12  during  the  year  ended  December  31,  2015  and  paid  four  quarterly 
dividends of $0.10 during the year ended December 31, 2014.

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,  2015,  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  by  the  third  quarter 
of 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 received $197 million 
of this deposit in 2015 and will receive the additional $197 million in 2016. 
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 2015, there were no credit memoranda issued.

Capital Spending
Capital  spending  totaled  $1.3  billion  in  2015,  slightly  above  the  amount 
spent  in  2014.  Spending  in  2015  was  driven  primarily  by  the  Display 
Technologies  segment,  and  focused  on  finishing  line  optimization 
and  tank  rebuilds.  We  expect  our  2016  capital  expenditures  to  be 
approximately  $1.3  billion.  Approximately  $600  million  will  be  allocated 
to our Display Technologies segment.

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 foreign currency hedges related to translated earnings, offset 
by higher capital spending and several acquisitions that were completed 
in 2015.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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.

2014 vs. 2013

Net  cash  provided  by  operating  activities  increased  significantly  in 
the  year  ended  December  31,  2014,  when  compared  to  the  same  period 
last  year,  due  to  a  dividend  of  approximately  $1,574  million  received 
from  Samsung  Corning  Precision  Materials,  an  increase  in  net  income 
of  $511  million  and  the  cash  inflows  from  inventory  movements. 
Although  net  inventory  increased  by  $52  million  due  to  the  acquisition 
of  Samsung  Corning  Precision  Materials,  which  added  $121  million, 
this  inventory  was  acquired  through  the  issuance  of  preferred  stock. 
Cash  outflows  for  inventory  declined  by  $120  million  in  the  Display 
Technologies and Specialty Materials segments in 2014 when compared 
to  2013,  offset  somewhat  by  an  increase  of  approximately  $50  million, 
driven by spending for new business development, and increases in the 
Optical Communications and Life Sciences segments.

Net cash used in investing activities decreased slightly in the year ended 
December 31, 2014, when compared to the same period last year, driven 
by  a  decrease  in  investments  in  unconsolidated  entities,  the  realized 
gains on our yen-denominated purchased collars and the absence of the 
premium paid for our yen-denominated purchased collars in 2013, offset 
by an increase in short-term investments.

Net  cash  used  in  financing  activities  in  the  year  ended  December  31, 
2014  increased  when  compared  to  the  same  period  last  year,  driven  by 
our share repurchase programs and the absence of the proceeds received 
in  2013  from  the  issuance  of  long-term  debt,  somewhat  offset  by  cash 
received  from  the  issuance  of  preferred  stock  and  the  absence  of  the 
retirement of long-term debt in the first quarter of 2013.

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, 2015,  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  2015, 
we  made  voluntary  cash  contributions  of  $65  million  to  our  domestic 
defined benefit pension plan and $35 million to our international pension 
plans.  In  2014,  we  made  voluntary  cash  contributions  of  $85  million 
to  our  domestic  defined  benefit  pension  plan  and  $45  million  to  our 
international  pension  plans.  In  2013,  we  did  not  contribute  to  our 
domestic  defined  benefit  pension  plan  and  contributed  $5  million  to 
our international pension plans. Although we will not be subject to any 
mandatory  contributions  in  2016,  we  anticipate  making  voluntary  cash 
contributions  of  up  to  $62  million  to  our  U.S.  pension  plan  and  up  to 
$36 million to our international pension plans in 2016.

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

Restructuring
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.

In the fourth quarter of 2013, Corning implemented a global restructuring 
plan within several of our segments, consisting of workforce reductions, 
asset  disposals  and  write-offs,  and  exit  costs.  We  recorded  charges  of 
$67  million  associated  with  these  actions,  with  total  cash  expenditures 
of $35 million.

purchase $1 billion of its common stock, in  total, with an initial delivery 
by  JPMC  of  47.1  million  shares  based  on  the  current  market  price,  and 
payment  of  $1  billion  made  by  Corning  to  JPMC. The  payment  to  JPMC 
was recorded as a reduction to shareholders’ equity, consisting of an $800 
million  increase  in  treasury  stock,  which  reflects  the  value  of  the  initial 
47.1 million shares received upon execution, and a $200 million decrease 
in  other-paid-in  capital,  which  reflects  the  value  of  the  stock  held  back 
by  JPMC  pending  final  settlement.  On  January  28,  2014,  the  2013  ASR 
agreement  was  completed.  Corning  received  an  additional  10.5  million 
shares  on  January  31,  2014  to  settle  the  2013  ASR  agreement.  In  total, 
Corning purchased 57.6 million shares based on the average daily volume 
weighted-average  price  of  Corning’s  common  stock  during  the  term  of 
the 2013 ASR agreement, less a discount.

In addition to the shares repurchased through the 2013 ASR agreement, 
we repurchased 61.3 million shares of common stock on the open market 
for  approximately  $1  billion,  as  part  of  the  2013  Repurchase  Program. 
This program was executed between the second quarter of 2013 and the 
first quarter of 2014, with a total of 118.9 million shares repurchased for 
approximately $2 billion.

March 2014 Repurchase Program

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 98.2 million shares repurchased 
for approximately $2 billion.

Management Assessment of Liquidity
We  ended  the  fourth  quarter  of  2015  with  approximately  $4.6  billion 
of  cash,  cash  equivalents  and  short-term  investments.  The  Company 
has adequate sources of liquidity and we are confident in our ability  to 
generate  cash  to  meet  reasonably  likely  future  cash  requirements.  Our 
cash,  cash  equivalents  and  short-term  investments  are  held  in  various 
locations throughout the world and are generally unrestricted. Although 
approximately 71% of the consolidated amount was held outside of the 
United  States  at  December  31,  2015,  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.

To manage interest rate exposure, the Company, from time to time, may 
enter into interest rate swap agreements. In the first quarter of 2015, the 
interest rate swaps that were entered into in the fourth quarter of 2014 
to  hedge  future  interest  payments  from  an  anticipated  debt  issuance 
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 also has a commercial paper program pursuant to which we may 
issue short-term, unsecured commercial paper notes up to a maximum 
aggregate principal amount outstanding at any time of $1 billion. Under 
this program, the Company may issue the notes from time to time and 
will  use  the  proceeds  for  general  corporate  purposes.  The  maturities 
of  the  notes  vary,  but  may  not  exceed  390  days  from  the  date  of  issue. 
The  interest  rates  vary  based  on  market  conditions  and  the  ratings 
assigned  to  the notes by credit rating agencies at  the  time of issuance. 
The Company’s revolving credit facility is available to support obligations 
under  the  commercial  paper  program,  if  needed.  At  December  31,  2015, 
we had a balance of $481 million in outstanding commercial paper under 
this program.

Share Repurchase Programs

2013 Repurchase Program

On October 31, 2013, as part of the share repurchase program announced 
on  April  24,  2013  (the  “2013  Repurchase  Program”),  Corning  entered 
into  an  accelerated  share  repurchase  (“ASR”)  agreement  (the “2013  ASR 
agreement”)  with  JP  Morgan  Chase  Bank,  National  Association,  London 
Branch  (“JPMC”).  Under  the  2013  ASR  agreement,  Corning  agreed  to

December 2014 Repurchase Program

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. In the year ended December 31, 2015, we repurchased 
70.4 million shares of common stock for approximately $1.5 billion as part 
of the December 2014 Repurchase Program, which was completed in the 
third quarter of 2015.

2015 Repurchase Programs

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 
&  Co.  LLC  (“Morgan  Stanley”)  to  repurchase  $1.25  billion  of  Corning’s 
common stock (the “2015 ASR agreement”). The 2015 ASR agreement 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.  The  payment  to  Morgan  Stanley  was  recorded  as  a 
reduction  to  shareholders’  equity,  consisting  of  a  $1  billion  increase  in 
treasury  stock,  which  reflects  the  value  of  the  initial  53.1  million  shares 
received  upon  execution,  and  a  $250  million  decrease  in  other-paid-
in  capital,  which  reflects  the  value  of  the  stock  held  back  by  Morgan 
Stanley  pending  final  settlement.  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 151 
million shares repurchased during 2015.

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.

Our major source of funding for 2016 and beyond will be our operating 
cash  flow  and  our  existing  balances  of  cash,  cash  equivalents,  short-
term investments 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,  2015,  our  leverage 
using  this  measure  was  19%  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,  2015,  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.

Purchased Collars, Zero-Cost Collars and Average 
Rate Forwards
In the first quarter of 2013, Corning executed a series of purchased collars 
that  expire  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 with no associated premium to hedge 
the  translation  impact  of  Japanese  yen  on  Corning’s  projected  2015, 
2016  and  2017  net  income.  Additionally,  in  January  2016,  Corning  took 
advantage  of  the  stronger  yen  to  extend  its  foreign  exchange  hedging 
program to hedge a significant portion of its projected yen exposure for 
the period 2018 through 2022. In the years ended December 31, 2015, 2014 
and 2013, we recorded pre-tax net gains of $113 million, $1,406 million and 
$435  million,  respectively,  related  to  changes  in  the  fair  value  of  these 
derivative  instruments.  Included  in  these  amounts  are  realized  gains  of 
$686 million, $280 million and $67 million, respectively. The gross notional 
value outstanding for purchase collars and average rate forwards which 
hedge our exposure to the Japanese yen at December 31, 2015, 2014 and 
2013 was $8.3 billion, $9.8 billion and $6.8 billion, respectively.

Beginning  in  the  second  quarter  of  2014,  and  continuing  throughout 
2015,  we  entered  into  a  portfolio  of  zero-cost  collars  to  hedge  our 
translation exposure resulting from movements in the South Korean won 
and its impact on our net earnings. In 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  zero-cost 
collars. Included in these amounts are realized losses of $33 million and 
$6  million,  respectively.  These  zero-cost  collars  have  a  gross  notional 
value  outstanding  at  December  31,  2015  and  2014  of  $3.3  billion  and 
$2.3 billion, respectively.

In the first quarter of 2015, in response to the significant strengthening 
of the U.S. dollar versus the euro, we entered into a portfolio of zero-cost 
collars and average rate forwards with an associated premium to hedge 
against  our  euro  translation  exposure.  In  the  year  ended  December  31 
2015,  we  recorded  a  net  pre-tax  gain  of  $3  million. These  collars  have  a 
gross notional amount of $345 million at December 31, 2015.

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 foreign currency 
hedge 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.

Contractual Obligations
The amounts of our obligations follow (in millions):

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 one entity that qualifies as a variable interest entity. 
This entity is 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, 2015, $38 million of the $47 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.

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.

We are required, at the time a guarantee is issued, to recognize a liability

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

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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,  2015  and 
2014,  Corning  had  accrued  approximately  $37  million  (undiscounted) 
and  $43  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.

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 
impairments include, but are not limited to:

indicative  of 

• 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 described above, the 
estimated fair value of long-lived assets is determined using an “income 
approach”, “market  approach”, “cost  approach”,  or  a  combination  of  one 
or  more  of  these  approaches  as  appropriate  for  the  particular  asset 
group  being  reviewed.  All  of  these  approaches  start  with  the  forecast 
of 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 if appropriate for the asset group being reviewed. 
Some of the more significant estimates and assumptions in our analysis 
include:  market  size  and  growth,  market  share,  projected  selling  prices, 
manufacturing cost and discount rate. 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.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

In the event the current net book value of an asset group is found to be 
greater  than  the  net  present  value  of  the  cash  flows  derived  from  the 
asset  group,  we  determine  the  actual  fair  market  value  of  long-lived 
assets with the assistance from valuation appraisals conducted by third 
parties. The results of these valuations generally represent the fair market 
value of the asset group that will remain after any necessary impairment 
adjustments have been recorded. The impairment charge will be allocated 
to assets within the asset group on a relative fair value basis.

At  December  31,  2015  and  December  31,  2014,  the  carrying  value  of 
precious  metals  was  higher  than  the  fair  market  value  by  $976  million 
and  $222  million,  respectively. 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.

• 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;

46

–  Overall  financial  performance,  such  as  negative  or  declining  cash 

flows or a decline in actual or forecasted revenue;

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

management or key personnel; and

–  Events affecting a reporting unit, such as a change in the composition 
including  acquisitions 

its  net  assets 

or  carrying  amount  of 
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 2015, 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 
assessment,  we  have  aggregated  these  two  components  into  one 
reporting  unit  based  upon  their  similar  economic  characteristics.  On  a 
quarterly basis in 2015, 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.

Specialty Materials

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 2015, 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 
2015,  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 2015, 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.

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
In  October  2013,  Corning  announced  that  it  was  entering  into  a  series 
of  strategic  and  financial  agreements  with  Samsung  Display  which 
would  result  in  Corning  obtaining  full  ownership  of  Samsung  Corning 
Precision  Materials.  As  part  of  this  agreement,  in  the  fourth  quarter  of 
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 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 articles of this entity, Corning did not 
consolidate this entity as of December 31, 2013. The remaining transactions 
were completed on January 15, 2014, which increased Corning’s ownership 
to 100% and resulted in consolidation of the entity beginning in the first 
quarter of 2014. This organization was integrated into Corning’s Display 
Technologies  segment  in  2014.  Refer  to  Note  8  (Acquisitions)  to  the 
Consolidated Financial Statements for additional information.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

On  December  11,  2015,  Corning  announced  its  intention  to  exchange  its 
50%  equity  interest  in  Dow  Corning  Corporation  for  100%  of  the  stock 
of a newly formed entity that will become a wholly-owned subsidiary of 
Corning  Incorporated. The  newly  formed  entity  will  hold  approximately 
40%  ownership  in  Hemlock  Semiconductor  Group  and  approximately 
$4.8  billion  in  cash.  Upon  completion  of  this  strategic  realignment, 
which is expected to close during the first half of 2016, Dow Chemical, an 
equal owner of Dow Corning with Corning since 1943, will assume 100% 
ownership of Dow Corning.

At December 31, 2015 and 2014, the carrying value of our equity method 
investments was $1.9 billion and $1.8 billion, respectively, with our largest 
equity  method  investment,  Dow  Corning,  comprising  78%  and  74%, 
respectively, of the balance. 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,  2015  and 
2014, 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 and euro. These contracts are not designated as accounting hedges, 
and  changes  in  their  fair  value  are  recorded  in  earnings  in  the  foreign 
currency hedge 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.

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.

Additionally, as a result of the acquisitions of iBwave Solutions Inc. and the 
fiber-optics business of Samsung Electronics Co., Ltd. in the first quarter 
of 2015,  the Company has contingent consideration  that was measured 
using unobservable (Level 3) inputs. As of December 31, 2015, the fair value 
of the contingent consideration payable is $10 million.

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

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. The  most  significant  matter  involving  judgment  is  the  liability 
for  asbestos  litigation. There  are  a  number  of  factors  bearing  upon  our 
potential liability, including the inherent complexity of a Chapter 11 filing, 
our history of success in defending asbestos claims, our assessment of the 
strength of our corporate veil defenses, and our continuing dialogue with 
our  insurance  carriers  and  the  claimants’  representatives. The  proposed 
asbestos  resolution  (Amended  PCC  Plan)  is  subject  to  a  number  of 
contingencies. As noted in Part II – Item 3. Legal Proceedings, the District 
Court’s affirmation of the Amended PCC Plan faces objections by certain 
parties. For these and other reasons, Corning’s liability for these asbestos 
matters may be subject to changes in subsequent quarters. The estimate 
of the cost of resolving the non-PCC asbestos claims may also be subject 
to change as developments occur. Management continues to believe that 
the likelihood of the uncertainties surrounding these proceedings causing 
a material adverse impact to Corning’s financial statements is remote.

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.

CORNING INCORPORATED - 2015 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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 including 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.

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  is  changing  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 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, 2016, net periodic pension and OPEB costs 
will  be  lower  by  approximately  $28  million  and  $6  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.

As of December 31, 2015, the Projected Benefit Obligation (PBO) for U.S. pension plans was $3,161 million.

The following information illustrates the sensitivity to a change in certain assumptions for U.S. pension 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.  These  changes  in  assumptions 
would have no effect on Corning’s funding requirements.

In addition, at December 31, 2015, a  25 basis point decrease in each spot 
rate would decrease stockholders’ equity by $110 million before tax, and 
a 25 basis point increase in each spot rate would increase stockholders’ 
equity by $105 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.

assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear.

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.

New Accounting Standards

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-

CORNING INCORPORATED - 2015 Annual ReportQuantitative and Qualitative Disclosures About 
Market Risks

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  renminbi,  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 with which we have other financial relationships 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 purchased 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,  2015, 
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 $901 million compared to $1,080 million at December 31, 2014. 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  of  $741 
million  compared  to  $959  million  at  December  31,  2014.  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 
$99 million compared to $79 million at December 31, 2014.

Because  we  derive  approximately  70%  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.  Our  forecasts 
generally  assume  exchange  rates  during  2016  will  remain  constant  at 
January 2016 levels. As an example of the impact that changes in foreign 
currency exchange rates could have on our financial results, we compare 
2015  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 2015 net sales 
of approximately $309 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 2015 net sales of approximately $5 million and $92 
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 
2015  net  income  attributable  to  Corning  Incorporated  of  approximately 
$188  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 2015 net income attributable to Corning Incorporated of approximately 
$67 million and $22 million, respectively.

Interest Rate Risk Management
It  is  our  policy  to  conservatively  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 INCORPORATED - 2015 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 
Dow  Corning  is  the  responsibility  of  Dow  Corning  management.  Based 
on  this  evaluation,  management  concluded  that  Corning’s  internal 
control over financial reporting was effective as of December 31, 2015. The 
effectiveness  of  Corning’s  internal  control  over  financial  reporting  as  of 
December 31, 2015, has been audited by PricewaterhouseCoopers LLP, an 
independent registered public accounting firm, as stated in their report 
which is included herein.

CORNING INCORPORATED - 2015 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, 2015 
and 2014, and the results of its operations and its cash flows for each of 
the three years in the period ended December 31, 2015 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, 2015, 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.

As  discussed  in  Note  1  to  the  consolidated  financial  statements,  the 
Company  changed  the  manner  in  which  it  presents  deferred  income 
taxes in 2015.

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 - 2015 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.  In  the  fourth  quarter  of  2013,  Corning  acquired  the 
minority interests of three shareholders in one of our affiliated companies, 
Samsung  Corning  Precision  Materials,  which 
increased  Corning’s 
ownership  percentage  from  50%  to  57.5%.  Because  this  transaction 
did not result in a change in control based on  the governing articles of 
this  entity,  Corning  did  not  consolidate  this  entity  as  of  December  31, 
2013.  Corning  acquired  the  remaining  ownership  interests  of  Samsung 
Corning Precision Materials on January 15, 2014, which increased Corning’s 
ownership to 100% and resulted in consolidation of the entity beginning 
in the first quarter of 2014.

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 
eliminated in consolidation.

intercompany  accounts,  transactions  and  profits  are 

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”)
As further discussed in Note 8 (Acquisitions) to the Consolidated Financial 
Statements, 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  is  now 
the owner of 100% of the common shares of Samsung Corning Precision 
Materials, which we have 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.

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.

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.

59

CORNING INCORPORATED - 2015 Annual Report 
Notes to Consolidated Financial Statements

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 $638 million in 2015, $701 million 
in 2014 and $613 million in 2013.

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 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.

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.  Foreign  currency  transaction  losses  for  the  years  ended 
December  31,  2015,  2014  and  2013  were  $22  million,  $60  million  and 
$190 million, respectively.

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.

equipment, net of accumulated depreciation, in 2015, 2014 and 2013, respectively.

Short-Term Investments
Our  short-term  investments  consist  of  available-for-sale  securities  that 
are stated at fair value. Consistent with Corning’s cash investment policy, 
our short-term investments consist primarily of fixed-income securities. 
Preservation of principal is the primary principle of our cash investment 
policy that is carried out by limiting interest rate, reinvestment, security, 
quality  and  event  risk.  Our  investments  are  generally  liquid  and  all  are 
investment  grade  quality.  The  portfolio  is  invested  predominantly  in 
U.S. government securities and quality money market funds. Unrealized 
gains  and  losses,  net  of  tax,  are  computed  on  a  specific  identification 
basis  and  are  reported  as  a  separate  component  of  accumulated  other 
comprehensive loss in shareholders’ equity until realized. Realized gains 
and losses are recorded in other (expense) income, net.

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. 

60

CORNING INCORPORATED - 2015 Annual Report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.

Notes to Consolidated Financial Statements

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.

Other intangible assets 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.

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. 

61

CORNING INCORPORATED - 2015 Annual ReportNotes to Consolidated Financial Statements

two 
for  our  defined  benefit  pension  plans  consist  of 
Costs 
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  and  for  the  retirement  or 
conversion of certain debt instruments. 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 
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 
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.

indefinitely  reinvested 

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.

CORNING INCORPORATED - 2015 Annual ReportNotes to Consolidated Financial Statements

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 statement 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  designated  as  fair 
value hedges are recorded currently in earnings offset, to the extent the 
derivative  was  effective,  by  the  change  in  the  fair  value  of  the  hedged 
item. Changes in the fair value of derivatives not designated as hedging 
instruments  are  recorded  currently  in  earnings  in  the  Foreign  currency 
hedge gain, net line of the consolidated statement of income.

New Accounting Standards 
In  May  2014,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued 
Accounting  Standards  Update  No.  (“ASU”)  2014-09,  Revenue  from 
Contracts  with  Customers,  as  a  new  Topic,  Accounting  Standards 
Codification  (“ASC”)  Topic  606.  The  new  revenue  recognition  standard 
provides  a  five-step  analysis  of  transactions  to  determine  when  and 
how revenue is recognized. The core principle is  that a company should 

recognize  revenue  to  depict  the  transfer  of  promised  goods  or  services 
to customers in an amount that reflects the consideration to which the 
entity  expects  to  be  entitled  in  exchange  for  those  goods  or  services. 
This  ASU  originally  was  effective  for  annual  periods  beginning  after 
December 15, 2016, including interim periods within that reporting period. 
This ASU shall be applied retrospectively to each period presented or as a 
cumulative-effect adjustment as of the date of adoption. 

In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with 
Customers  (Topic  606),  deferring  the  effective  date  of  ASU  2014-09  by 
one year. We can elect to adopt the provisions of ASU 2014-09 for annual 
periods  beginning  after  December  15,  2017,  including  interim  periods 
within  that  reporting  period. The  FASB  also  agreed  to  allow  entities  to 
choose  to  adopt  the  standard  as  of  the  original  effective  date. We  are 
currently assessing the adoption date and potential impact of adopting 
ASU 2014-09 on our financial statements and related disclosures.

issued  ASU  2015-17, 

Income  Taxes 
In  November  2015,  the  FASB 
(Topic 740), requiring deferred tax assets and liabilities to be classified as 
noncurrent in a classified balance sheet. This ASU is effective for annual 
periods  beginning  after  December  15,  2016,  and  interim  periods  within 
those  annual  periods.  Early  adoption  is  permitted  as  of  the  beginning 
of  an  interim  or  annual  reporting  period.  We  have  adopted  this  ASU 
prospectively for the year ended December 31, 2015. See Note 6 (Income 
Taxes) to the Consolidated Financial Statements for additional information.

2.  Restructuring, Impairment and Other Charges

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,  asset  disposals  and  write-offs,  and  exit  costs  for 
restructuring activities with total cash expenditures of approximately $39 million.

2013 Activity
To  better  align  our  2014  cost  position  in  several  of  our  businesses, 
Corning  implemented  a  global  restructuring  plan  within  several  of 
our  segments  in  the  fourth  quarter  of  2013,  consisting  of  workforce 

reductions,  asset  disposals  and  write-offs,  and  exit  costs.  We  recorded 
charges  of  $67  million,  before  tax,  associated  with  these  actions,  with 
cash expenditures of $35 million.

We do not intend 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.

(1)  Primarily related  to a subsidiary in Taiwan operating under  tax holiday arrangements. The nature and extent of such arrangements vary, and  the 
benefits of existing arrangements phase out in future years (through 2018). The impact of tax holidays on net income per share on a diluted basis was 
$0.01 in 2015, $0.01 in 2014 and $0.02 in 2013.

(2) Primarily related to research and development and other credits in the U.S.

(3) Equity in earnings of nonconsolidated affiliates reported in the financials net of tax. The difference between 2013-2014 was due to  the change of 

Samsung Corning Precision Materials from an equity company to a consolidated entity.

(4) In 2013, $74 million of tax benefit increase was due to $37 million expense recorded in 2012 that was reversed in the first quarter of 2013 as a result 
of  the  retroactive  application  of  the  American Taxpayer  Relief  Act  enacted  on  January  3,  2013.  In  2013,  the  additional  increase  in  the  benefit  was 
attributable to excess foreign tax credits realized in U.S. from a taxable intercompany loan.

(5)  Primarily related to change in judgment on the realizability of Australia and certain state deferred tax assets.

(6) $177 million tax expense related to change in judgment on the realizability of Germany and Japan deferred tax assets is partially offset with benefit 
from state deferred tax asset valuation allowance reductions, including the valuation allowance relating to the New York State attribute reduction 
discussed in (9) below.

(7)  $100 million tax benefit primarily related to change in judgment on the realizability of Germany and Japan deferred tax assets is partially offset with 

tax expense from U.S. state and China deferred tax allowance increases.

(8) Includes in 2014, $9 million benefit for domestic manufacturing deduction and $46 million of tax expense related to out of period transfer pricing 

adjustments. The impact of these corrections is not material to any individual period previously presented.

(9) Includes  $100  million  tax  expense  related  to  the  write-off  of  New  York  State  tax  attributes  for  a  state  law  change  that  were  offset  with  full 

valuation allowance.

(10) Unrecognized tax benefit reserve was primarily for tax positions taken related to transfer pricing 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.

(11) Tax benefit is primarily for excess foreign tax credits resulting from the inclusion of high-taxed foreign earnings in U.S. income and the income of 
Taiwan and Korea subsidiaries with lower statutory rates than the U.S. The amount of tax benefit in 2015 is relatively consistent with 2014. The change 
in the effective tax rate reconciliation percentage is driven by the significant decrease in the gain on our foreign currency translation hedges in 2015 
versus 2014.

The recognition of windfall tax benefits from share-based compensation 
deducted on the tax return is prohibited until realized through a reduction 
of income tax payable. Cumulative tax benefits totaling $244 million will 
be  recorded  in  additional  paid-in-capital  when  credit  carryforwards  are 
utilized and the windfall tax benefit can be realized.

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  $4.7  billion  will  be  required 
to  fully  realize  the  U.S.  deferred  tax  assets  as  of  December  31,  2015,  of 
which $88 million will be required over  the next 20 years  to realize  the 
deferred tax assets related to general business credits and $1.9 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, 2015 and 2014 was $238 million and 
$298 million, respectively.

The  additions  for  tax  positions  of  prior  years  include  $221  million  for 
unrecognized tax benefits related to gross transfer pricing adjustments. 
See  footnote  (10)  of  the  Reconciliation  of  the  U.S.  statutory  income  tax 
rate  to  our  effective  tax  rate  for  continuing  operations  above  for  more 
information. Included in  the balance at December 31, 2015 and 2014 are 
$102 million and $5 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 year ended December 31, 2015 the 
amount recognized in interest expense is $6 million. In 2014 and 2013, the 
amounts  recognized  in  interest  expense  and  income  were  immaterial. 
The amounts accrued at December 31, 2015 and 2014 for the payment of 
interest and penalties was $5 million and $1 million, respectively.

While we expect the amount of unrecognized tax benefits to change in 
the next 12 months, we do not expect  the change  to have a significant 
impact on the results of operations or our financial position.

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.  All  such  returns  for  periods  ended  through 
December  31,  2004,  have  been  audited  by  and  settled  with  the  Internal 
Revenue  Service  (IRS). The  statute  of  limitations  is  closed  for  all  returns 
prior to 2002, but the IRS can make adjustments for the return in which 
the NOL, U.S. foreign tax and research experimentation credit carryovers 
are utilized.

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 
onward), Taiwan (2014 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 
that  may  impact  our  ability  or  intent  to  keep  our  foreign  earnings  and 
cash  indefinitely  reinvested  include  significant  U.S.  acquisitions,  stock 
repurchases,  shareholder  dividends,  changes  in  tax  laws,  derivative 
contract settlements or the development of tax planning ideas that allow 
us  to repatriate earnings at minimal or no  tax cost, and/or a change in 
our  circumstances  or  economic  conditions  that  negatively  impact  our 
ability to borrow or otherwise fund U.S. needs from existing U.S. sources. 
As of December 31, 2015, taxes have not been provided on approximately 
$11  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.

(2) As a result of the series of strategic and financial agreements with Samsung Display entered into on October 22, 2013, certain non-operating assets 
of Samsung Corning Precision Materials were held for sale as of December 31, 2013 and are reported as discontinued operations in Samsung Corning 
Precision  Materials  financial  statements,  which  are  attached  in  Item  15,  Exhibits  and  Financial  Schedules.  Previous  period  amounts  have  been 
conformed for comparative purposes.

(3) In 2013, Corning purchased machinery and equipment on behalf of Samsung Corning Precision Materials to support its capital expansion initiative.

We have contractual agreements with several of our equity affiliates which include sales, purchasing, licensing and technology agreements.

At December 31, 2015, approximately $2.0 billion of equity in undistributed earnings of equity companies was included in our retained earnings.

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.

(1)  Gross profit for the year ended December 31, 2015 includes R&D cost of $233 million (2014: $273 million and 2013: $248 million).

In  May  1995,  Dow  Corning  filed  for  bankruptcy  protection  to  address 
pending  and  claimed  liabilities  arising  from  breast  implant  product 
lawsuits.  On  June  1,  2004,  Dow  Corning  emerged  from  Chapter  11  with 
a Plan of Reorganization (the “Plan”) which provided for  the settlement 
or other resolution of implant claims. The Plan also includes releases for 
Corning and Dow Chemical as shareholders in exchange for contributions 
to the Plan.

Under the terms of the Plan, Dow Corning has established and is funding 
a  Settlement  Trust  and  Litigation  Facility  (the  “Settlement  Facility”)  to 
provide a means for tort claimants to settle or litigate their claims. The Plan 
contains a cap on the amount of payments required from Dow Corning to 
fund the Settlement Facility. Inclusive of insurance, Dow Corning has paid 
approximately  $1.8  billion  to  the  Settlement  Facility,  and  approximately 
$1.3 billion has been paid to claimants out of the Settlement Facility. As of 
December 31, 2015, Dow Corning had recorded a reserve for breast implant 
litigation of $291 million.

During the fourth quarter of 2014, Dow Corning, with the assistance of a 
third-party advisor, developed an estimate of the future Implant Liability 
based  on  evidence  that  the  actual  funding  required  for  the  Settlement 
Facility is expected to be lower than the full funding cap set forth in the 
Plan.  On  December  12,  2014,  Dow  Corning  reduced  its  Implant  Liability 
by  approximately  $1.3  billion  (Corning’s  share  after-tax:  $393  million). 
Previously,  the  Implant  Liability  was  based  on  the  full  funding  cap  set 
forth in the Plan. The revised Implant Liability reflects Dow Corning’s best 
estimate  of  its  remaining  obligations  under  the  Plan.  Should  events  or 
circumstances occur in the future which change Dow Corning’s estimate 
of the remaining funding obligations; the Implant Liability will be revised. 
This  adjustment  does  not  affect  Dow  Corning’s  commitment  or  ability 
to fulfill its obligations under the settlement, and all claims that qualify 
under the settlement will be paid according to the terms of the Plan.

As  a  separate  matter  arising  from  its  bankruptcy  proceedings,  Dow 
Corning is defending claims asserted by a number of commercial creditors 
who  claim  additional  interest  at  default  rates  and  enforcement  costs, 
during the period from May 1995 through June 2004. As of December 31, 
2015, Dow Corning has estimated the potential liability to these creditors 
to  be  within  the  range  of  $104  million  to  $341  million.  As  Dow  Corning 
management believes no single amount within the range appears to be 
a better estimate than any other amount within the range, Dow Corning 
has recorded the minimum liability within the range. Should Dow Corning 
not prevail in this matter, Corning’s equity earnings would be reduced by 
its 50% share of the amount in excess of $104 million, net of applicable tax 
benefits. There are a number of other claims in the bankruptcy proceedings 
against Dow Corning awaiting resolution by the U.S. District Court, and it 
is reasonably possible that Dow Corning may record bankruptcy-related 
charges in the future. The remaining tort claims against Dow Corning are 
expected  to  be  channeled  by  the  Plan  into  facilities  established  by  the 
Plan or otherwise defended by the Litigation Facility.

On  December  11,  2015,  Corning  announced  its  intention  to  exchange  its 
50%  equity  interest  in  Dow  Corning  Corporation  for  100%  of  the  stock 
of a newly formed entity that will become a wholly owned subsidiary of 
Corning  Incorporated. The  newly  formed  entity  will  hold  approximately 
40%  ownership  in  Hemlock  Semiconductor  Group  and  approximately 
$4.8  billion  in  cash.  Upon  completion  of  this  strategic  realignment, 
which is expected to close during the first half of 2016, Dow Chemical, an 
equal owner of Dow Corning with Corning since 1943, will assume 100% 
ownership of Dow Corning.

CORNING INCORPORATED - 2015 Annual ReportPittsburgh Corning Corporation and Asbestos Litigation.

Corning and PPG Industries, Inc. (“PPG”) each own 50% of the capital stock 
of  Pittsburgh  Corning  Corporation  (“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.  On  April  16,  2000,  PCC  filed  for  Chapter  11  reorganization  in 
the  U.S.  Bankruptcy  Court  for  the  Western  District  of  Pennsylvania.  At 
the  time PCC filed for bankruptcy protection,  there were approximately 
11,800  claims  pending  against  Corning  in  state  court  lawsuits  alleging 
various theories of liability based on exposure to PCC’s asbestos products 
and  typically  requesting  monetary  damages  in  excess  of  one  million 
dollars per claim. Corning has defended those claims on the basis of the 
separate corporate status of PCC and the absence of any facts supporting 
claims of direct liability arising from PCC’s asbestos products.

PCC Plan of Reorganization

Corning, with other relevant parties, has been involved in ongoing efforts 
to  develop  a  Plan  of  Reorganization  that  would  resolve  the  concerns 
and objections of the relevant courts and parties. On November 12, 2013, 
the  Bankruptcy  Court  issued  a  decision  finally  confirming  an  Amended 
PCC  Plan  of  Reorganization  (the “Amended  PCC  Plan”  or  the “Plan”).  On 
September  30,  2014,  the  United  States  District  Court  for  the  Western 
District  of  Pennsylvania  (the  “District  Court”)  affirmed  the  Bankruptcy 
Court’s decision confirming the Amended PCC Plan. On October 30, 2014, 
one of the objectors to the Plan appealed the District Court’s affirmation 
of the Plan to the United States Court of Appeals for the Third Circuit (the 
“Third Circuit Court of Appeals”). On January 6, 2016, all pending appeals 
of  the  Plan  were  withdrawn  and  Corning  expects  that  the  Plan  will 
become effective in April 2016.

Under  the  Plan  as  affirmed  by  the  Bankruptcy  Court  and  affirmed  by 
the  District  Court,  Corning  is  required  to  contribute  its  equity  interests 
in PCC and Pittsburgh Corning Europe N.V. (“PCE”), a Belgian corporation, 
and to contribute $290 million in a fixed series of payments, recorded at 
present value. Corning will contribute its equity interest in PCC and PCE 
on the Plan’s Funding Effective Date, which is expected to occur in June 
2016. Corning has the option to use its common stock rather than cash 
to  make  these  payments,  but  the  liability  is  fixed  by  dollar  value  and 
not  the  number  of  shares.  The  Plan  requires  Corning  to  make:  (1)  one 
payment of $70 million one year from the date the Plan becomes effective 
and  certain  conditions  are  met;  and  (2)  five  additional  payments 
of  $35  million,  $50  million,  $35  million,  $50  million,  and  $50  million, 
respectively,  on  each  of  the  five  subsequent  anniversaries  of  the  first 
payment, the final payment of which is subject to reduction based on the 
application of credits under certain circumstances.

Non-PCC Asbestos Litigation

In addition to the claims against Corning related to its ownership interest 
in PCC, Corning is also the defendant in approximately 9,700 other cases 
(approximately 37,300 claims) alleging injuries from asbestos related to 
its Corhart business and similar amounts of monetary damages per case 
(the “non-PCC asbestos claims”). When PCC filed for bankruptcy protection, 
the Court granted a preliminary injunction to suspend all asbestos cases 
against PCC, PPG and Corning – including these non-PCC asbestos claims 
(the “Stay”). The Stay remains in place as of the date of this filing; however, 

Notes to Consolidated Financial Statements

given that the Amended PCC Plan is now affirmed by the District Court 
and the Third Circuit Court of Appeals, Corning anticipates the Stay will 
be lifted in the second half of 2016. These non-PCC asbestos claims have 
been covered by insurance without material impact to Corning to date. As 
of December 31, 2015, Corning had received for these claims approximately 
$19  million  in  insurance  payments. When  the  Stay  is  lifted,  these  non-
PCC asbestos claims will be allowed to proceed against Corning. In prior 
periods, Corning recorded in its estimated asbestos litigation liability an 
additional $150 million for these and any future non-PCC asbestos claims.

Total  Estimated  Liability  for  the  Amended  PCC  Plan  and  the  Non-PCC 
Asbestos Claims

The liability for the Amended PCC Plan and the non-PCC asbestos claims 
was  estimated  to  be  $678  million  at  December  31,  2015,  compared 
with  an  estimate  of  liability  of  $681  million  at  December  31,  2014.  The 
$678  million  liability  is  comprised  of  $238  million  of  the  fair  value  of 
PCE,  $290  million  for  the  fixed  series  of  payments,  and  $150  million  for 
the non-PCC asbestos claims, all referenced in the preceding paragraphs. 
With respect to the PCE liability, at December 31, 2015 and 2014, the fair 
value of $238 million and $241 million of our interest in PCE significantly 
exceeded its carrying value of $154 million and $162 million, respectively. 
There have been no impairment indicators for our investment in PCE and 
we  continue  to  recognize  equity  earnings  of  this  affiliate.  At  the  time 
Corning recorded this liability, it determined it lacked the ability to recover 
the  carrying  amount  of  its  investment  in  PCC  and  its  investment  was 
other than temporarily impaired. As a result, we reduced our investment 
in PCC  to zero. As  the fair value in PCE is significantly higher  than book 
value,  management  believes  that  the  risk  of  an  additional  loss  in  an 
amount  materially  higher  than  the  fair  value  of  the  liability  is  remote. 
With  respect  to  the  liability  for  other  asbestos  litigation,  the  liability 
for  non-PCC  asbestos  claims  was  estimated  based  upon  industry  data 
for  asbestos  claims  since  Corning  does  not  have  recent  claim  history 
due  to  the  Stay  issued  by  the  Bankruptcy  Court. The  estimated  liability 
represents  the undiscounted projection of claims and related legal fees 
over  the  next  20  years. The  amount  may  need  to  be  adjusted  in  future 
periods  as  more  data  becomes  available;  however,  we  cannot  estimate 
any additional losses at this time. For the years ended December 31, 2015 
and 2014, Corning recorded asbestos litigation income of $15 million and 
expense  of  $9  million,  respectively.  At  December  31,  2015,  $440  million 
of  the  obligation,  consisting  of  the  $290  million  for  the  fixed  series  of 
payments and $150 million for the non-PCC asbestos claims, is classified as 
a non-current liability, as installment payments for the cash portion of the 
obligation are not planned to commence until more than 12 months after 
the Amended PCC Plan becomes effective. The amount of the obligation 
related to the fair value of PCE, $238 million, was reclassified to a current 
liability in the fourth quarter of 2015, as the contribution of the assets is 
expected to be made within the next twelve months.

Non-PCC Asbestos Claims Insurance Litigation

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.

CORNING INCORPORATED - 2015 Annual ReportNotes to Consolidated Financial Statements

8.  Acquisitions

Year ended December 31, 2015 

Corning completed five acquisitions in 2015. There have been 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 
purchase accounting for four acquisitions. The purchase accounting related to one acquisition in the fourth quarter of 2015 has not been completed and 
amounts related to this acquisition are subject to change. A summary of the allocation of the total purchase consideration for the five acquisitions is as 
follows (in millions):

(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  total  consideration  related  to  the  acquisitions  primarily  consisted 
of  cash  and,  in  two  of  the  acquisitions,  contingent  consideration.  The 
contingent consideration arrangements may require additional amounts 
to be paid in 2016 and 2017 based on projections of future revenues. The 
combined potential additional consideration is capped at $28 million. The 
total fair value of the contingent consideration for the two acquisitions 
was valued at $13 million as of the acquisition date and $10 million as of 
December 31, 2015. The change in fair value of contingent consideration 
of  $3  million  was  recorded  as  an  adjustment  to  selling,  general  and 
administrative expenses.

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.

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.

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.

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.

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. 

72

CORNING INCORPORATED - 2015 Annual Report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.

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. 

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  $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. 

The following table summarizes the amounts of identified assets acquired and liabilities assumed at acquisition date and recorded measurement period 
adjustments. Corning has completed its accounting for the acquisition of Samsung Corning Precision Materials and its review of deferred taxes.

(1)  Cash  and  cash  equivalents  are  presented  net  of  the  2014  dividend  distributed  subsequent  to  the  acquisition  of  Samsung  Corning  Precision 

Materials, in the amount of $2.8 billion.

(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 $1,343 million and 
$1,761 million to net sales for the years ending December 31, 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.

Asbestos Litigation
Corning  and  PPG  each  own  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. The liability for the Amended PCC Plan 
and  the  non-PCC  asbestos  claims  was  estimated  to  be  $678  million  at 
December 31, 2015, compared with an estimate of liability of $681 million 
at December 31, 2014. At December 31, 2015, $440 million of the obligation, 
consisting of $290 million for the fixed series of payments and $150 million 
for  the  non-PCC  asbestos  claims,  is  classified  as  a  non-current  liability, 

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 by the third quarter of 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 

as  installment  payments  for  the  cash  portion  of  the  obligation  are  not 
planned  to  commence  until  more  than  12  months  after  the  Amended 
PCC Plan becomes effective. The amount of the obligation related to the 
fair value of PCE, $238 million, was reclassified to a current liability in the 
fourth quarter of 2015, as the contribution of the assets is expected to be 
made  within  the  next  twelve  months.  Refer  to  Note  7  (Investments)  to 
the Consolidated Financial Statements for additional information on the 
asbestos litigation.

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  received  $197  million  of  this 
deposit  in  2015  and  will  receive  the  additional  $197  million  in  2016.  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 2015, there were no credit memoranda issued.

CORNING INCORPORATED - 2015 Annual ReportDebt Issuances and Retirements

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.

2014

• In  the  third  quarter  of  2014,  we  amended  and  restated  our 
existing  revolving  credit  facility.  The  amended  facility  provides  a 
$2  billion  unsecured  multi-currency  line  of  credit  and  expires  on 
September 30, 2019. At December 31, 2015,  there were no outstanding 
amounts  on  this  credit  facility.  The  facility  includes  affirmative  and 
negative covenants that Corning must comply with, including a leverage 
(debt  to  capital  ratio)  financial  covenant.  As  of  December  31,  2015,  we 
were in compliance with all of the covenants.

2013

• In the first quarter of 2013, we amended and restated our then-existing 
revolving credit facility. The 2013 amended facility provided a $1 billion 
unsecured  multi-currency  line  of  credit  that  would  have  expired  in 
March  2018. This  facility  was  amended  and  restated  by  the  $2  billion 
facility entered into in the third quarter of 2014.

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  2015,  we  made 
voluntary  cash  contributions  of  $65  million  to  our  domestic  defined 
benefit  pension  plan  and  contributed  $35  million  to  our  international 
pension  plans.  In  2014,  we  made  voluntary  cash  contributions  of 
$85 million to our domestic defined benefit pension plan and contributed 
$45 million  to our international pension plans. Although we will not be 
subject  to  any  mandatory  contributions  in  2016,  we  anticipate  making 
voluntary cash contributions of up to $62 million to our domestic pension 
plan and up to $36 million to our international pension plans in 2016.

Notes to Consolidated Financial Statements

• In  the  first  quarter  of  2013,  Corning  repaid  the  aggregate  principal 
amount  and  accrued  interest  outstanding  on  the  credit  facility 
entered  into  in  the  second  quarter  of  2011  that  allowed  Corning  to 
borrow  up  to  Chinese  renminbi  (RMB)  4  billion.  The  total  amount 
repaid  was  approximately  $500  million.  Upon  repayment,  this  facility 
was terminated. 

• In the second quarter of 2013, the Company established a commercial 
paper program on a private placement basis, pursuant to which we may 
issue short-term, unsecured commercial paper notes up to a maximum 
aggregate principal amount outstanding at any time of $1 billion. Under 
this program, the Company may issue the notes from time to time and 
will  use  the  proceeds  for  general  corporate  purposes.  The  maturities 
of  the  notes  will  vary,  but  may  not  exceed  390  days  from  the  date  of 
issue. The interest rates will vary based on market conditions and  the 
ratings  assigned  to  the  notes  by  credit  rating  agencies  at  the  time  of 
issuance. The Company’s revolving credit facility is available to support 
obligations under the commercial paper program, if needed.

• In  the  fourth  quarter  of  2013,  we  issued  $250  million  of  3.70%  senior 
unsecured notes that mature on November 15, 2023. The net proceeds of 
approximately $248 million were used for general corporate purposes.

• In the fourth quarter of 2013, we recorded a financing obligation in the 
approximate  amount  of  $230  million  for  a  new  LCD  glass  substrate 
facility in China.

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 2016 for its defined benefit 
pension  plans.  The  Company  expects  to  recognize  $1  million  of  net 
actuarial gain and $4 million of net prior service credit as components of 
net periodic postretirement benefit cost in 2016.

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 - 2015 Annual Report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 

Notes to Consolidated Financial Statements

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  is  changing  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  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

60%  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.

9%  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,  2015  and  2014,  the  amount  of  Corning  common  stock 
included in equity securities was not significant.

Currency Risk

Cash Flow Data

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.

In  2016,  we  anticipate  making  voluntary  cash  contributions  of 
approximately  $62  million  to  our  domestic  defined  benefit  plan  and 
approximately $36 million to our international defined benefit plans.

The following reflects the gross benefit payments that are expected to be paid for our domestic and international defined benefit pension plans, the

(1)  At December 31, 2015, $38 million of the $47 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, 2015, $58 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.

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.

Corning  is  a  defendant  in  various  lawsuits,  including  environmental, 
product-related  suits,  the  Dow  Corning  and  PCC  matters  discussed  in 
Note  7  (Investments)  to  the  Consolidated  Financial  Statements,  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 INCORPORATED - 2015 Annual ReportNotes to Consolidated Financial Statements

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,  2015  and 
December  31,  2014,  Corning  had  accrued  approximately  $37  million 
(undiscounted)  and  $43  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,  2015,  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  renminbi,  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 with which we have other financial relationships 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. 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  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.  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.

Corning  uses  a  regression  analysis  to  monitor  the  effectiveness  of 
its  cash  flow  hedges  both  prospectively  and  retrospectively.  Through 
December 31, 2015, 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 (loss) 
income on the consolidated balance sheet until such time as the hedged 
item impacts earnings. At December 31, 2015, the amount expected to be 
reclassified into earnings within the next 12 months is a pre-tax net loss 
of $4.8 million.

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, 2015.

Net  gains  and  losses  from  fair  value  hedges  and  the  effects  of  the 
corresponding  hedged  item  are  recorded  on  the  same  line  item  of  the 
Consolidated Statement 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  are 
denominated in Japanese yen, South Korean won and euro. When these 
revenues are  translated back  to U.S. dollars,  the Company is exposed  to 
foreign exchange rate movements in the Japanese yen, South Korean won 
and  euro.  To  protect  translated  earnings  against  movements  in  these 
currencies, the Company has entered into a series of zero-cost collars and 
average rate forwards.

88

CORNING INCORPORATED - 2015 Annual ReportNotes to Consolidated Financial Statements

The Company also uses these types of contracts to reduce the potential 
for  unfavorable  changes  in  foreign  exchange  rates  to  decrease  the  U.S. 
dollar  value  of  translated  earnings.  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 foreign currency hedge 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, and span up  to 
the  fourth  quarter  of  2017.  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, 2015,  the U.S. dollar net notional value of  the zero-cost 
collar  is  $2.9  billion. The  Company  entered  into  a  series  of  average  rate 
forwards  with  no  associated  premium,  which  will  partially  hedge  the 
impact of Japanese yen and euro translation on the Company’s projected 

2015  through 2017 net income. These forwards have a notional value of 
$6.4 billion and will settle net without obligation to deliver Japanese yen 
and  euro.  In  January  2016,  Corning  took  advantage  of  the  stronger  yen 
to extend its foreign exchange hedging program  to hedge a significant 
portion of its projected yen exposure for the period 2018 through 2022.

The  Company  benefits  from  the  increase  in  the  U.S.  dollar  equivalent 
value of its foreign currency earnings in translation. The zero-cost collar 
would cap the benefit at the strike price of the written call or offset the 
decline from translation above the strike price of the purchased put.

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 foreign currency hedge 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

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.

Additionally, as a result of the acquisitions of iBwave Solutions Inc. and the 
fiber-optics business of Samsung Electronics Co., Ltd. in the first quarter 
of 2015,  the Company has contingent consideration  that was measured 
using unobservable (Level 3) inputs. As of December 31, 2015, the fair value

There were no significant financial assets and liabilities measured on a

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,  2015,  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

2013 Repurchase Program

On October 31, 2013, as part of the share repurchase program announced 
on  April  24,  2013  (the  “2013  Repurchase  Program”),  Corning  entered 
into  an  accelerated  share  repurchase  (“ASR”)  agreement  (the “2013  ASR 
agreement”)  with  JP  Morgan  Chase  Bank,  National  Association,  London 
Branch  (“JPMC”).  Under  the  2013  ASR  agreement,  Corning  agreed  to 
purchase $1 billion of its common stock, in  total, with an initial delivery 
by  JPMC  of  47.1  million  shares  based  on  the  current  market  price,  and 
payment  of  $1  billion  made  by  Corning  to  JPMC. The  payment  to  JPMC 
was recorded as a reduction to shareholders’ equity, consisting of an $800 
million  increase  in  treasury  stock,  which  reflects  the  value  of  the  initial 
47.1 million shares received upon execution, and a $200 million decrease 
in  other-paid-in  capital,  which  reflects  the  value  of  the  stock  held  back 
by  JPMC  pending  final  settlement.  On  January  28,  2014,  the  2013  ASR 
agreement  was  completed.  Corning  received  an  additional  10.5  million 
shares  on  January  31,  2014  to  settle  the  2013  ASR  agreement.  In  total, 
Corning purchased 57.6 million shares based on the average daily volume 
weighted-average  price  of  Corning’s  common  stock  during  the  term  of 
the 2013 ASR agreement, less a discount.

In addition to the shares repurchased through the 2013 ASR agreement, 
we repurchased 61.3 million shares of common stock on the open market 
for  approximately  $1  billion,  as  part  of  the  2013  Repurchase  Program. 
This program was executed between the second quarter of 2013 and the 
first quarter of 2014, with a total of 118.9 million shares repurchased for 
approximately $2 billion.

CORNING INCORPORATED - 2015 Annual ReportNotes to Consolidated Financial Statements

March 2014 Repurchase Program

2015 Repurchase Programs

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 98.2 million shares repurchased 
for approximately $2 billion.

December 2014 Repurchase Program

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. In the year ended December 31, 2015, we repurchased 
70.4 million shares of common stock for approximately $1.5 billion as part 
of the December 2014 Repurchase Program, which was completed in the 
third quarter of 2015.

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 
&  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.  The 
payment to Morgan Stanley was recorded as a reduction to shareholders’ 
equity,  consisting  of  $1  billion  increase  in  treasury  stock,  which  reflects 
the  value  of  the  initial  53.1  million  shares  received  upon  execution,  and 
a $250 million decrease in other-paid-in capital, which reflects the value 
of  the stock held back by Morgan Stanley pending final settlement. 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 
151 million shares repurchased during 2015.

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 continuing 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:

Employee stock options and awards

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,  2015,  there  were 
approximately  72  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  $46  million,  $58  million  and 
$54  million  was  disclosed  in  operating  activities  on  the  Company’s 
Consolidated Statements of Cash Flows for the years ended December 31, 
2015, 2014 and 2013, 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, 2015:

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  31,  2015, 
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, 2015, was 
approximately 13 million.

The  weighted-average  grant-date  fair  value  for  options  granted  for  the 
years ended December 31, 2015, 2014 and 2013 was $7.99, $8.29 and $5.02, 
respectively. The  total fair value of options  that vested during  the years 
ended December 31, 2015, 2014 and 2013 was approximately $36 million, 
$16  million  and  $29  million,  respectively.  Compensation  cost  related  to 
stock options for the years ended December 31, 2015, 2014 and 2013, was 
approximately $14 million, $22 million and $25 million, respectively.

As  of  December  31,  2015,  there  was  approximately  $7  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  $102  million 
for the year ended December 31, 2015, 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,  2015,  2014  and  2013  was  approximately  $48  million,  $69  million  and 
$55 million, respectively. The income tax benefit realized from share-based 
compensation was not significant for the years ended December 31, 2015 

and 2014. There were no income  tax benefits realized from share-based 
compensation for the year ended December 31, 2013, due to net operating 
loss and credit carryforwards available  to  the Company. Refer  to Note 6 
(Income Taxes).

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.

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.

As  of  December  31,  2015,  there  was  approximately  $27  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 2.3 years. The  total fair value of  time-based 
restricted  stock  that  vested  during  the  years  ended  December  31,  2015, 
2014 and 2013 was approximately $32 million, $32 million and $29 million, 
respectively.  Compensation  cost  related  to  time-based  restricted  stock 
and  restricted  stock  units  was  approximately  $32  million,  $36  million 
and  $29  million  for  the  years  ended  December  31,  2015,  2014  and 
2013, respectively.

and  a  glass  tubing  business  used  in  the  pharmaceutical  packaging 
industry.  This  segment  also  includes  Corning  Precision  Materials’  non-
LCD  business  and  new  product  lines  and  development  projects  such  as 
laser  technologies,  advanced  flow  reactors  and  adjacency  businesses  in 
pursuit of thin, strong glass, 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.

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,  2014,  and  changes  which  occurred  during  the  year  ended 
December 31, 2015:

(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) In 2013, equity in earnings of affiliated companies in the Display Technologies segment included a $28 million restructuring charge for our share of 

costs for headcount reductions and asset write-offs.

(4) 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.

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

companies and cost investments.

CORNING INCORPORATED - 2015 Annual Report 
 
 
Notes to Consolidated Financial Statements

For  the  year  ended  December  31,  2015,  the  following  number  of  customers,  which  individually  accounted  for  10%  or  more  of  each  segment’s  sales, 
represented the following concentration of segment sales:

• In the Display Technologies segment, three customers accounted for 62% of total segment sales.

• In the Optical Communications segment, two customers accounted for 22% of total segment sales.

• In the Environmental Technologies segment, three customers accounted for 86% of total segment sales.

• In the Specialty Materials segment, three customers accounted for 56% of total segment sales.

• In the Life Sciences segment, two customers accounted for 46% of total segment sales.

A significant amount of specialized manufacturing capacity for our Display Technologies segment is concentrated in Asia. It is at least reasonably possible 
that  the use of a facility located outside of an entity’s home country could be disrupted. Due  to  the specialized nature of  the assets, it would not be 
possible to find replacement capacity quickly. Accordingly, loss of these facilities could produce a near-term severe impact to our display business and 
the Company as a whole.
