Wendell P. Weeks
Chairman, Chief Executive Officer, 
and President

To Our Shareholders:

Corning had a very strong 2017. We grew core sales and earnings per share. We returned cash to shareholders through 
stock buybacks and a double-digit dividend increase. We introduced new products that continue Corning’s track record of 
producing life-changing innovations, while positioning the company for future growth. We strengthened our portfolio with 
strategic acquisitions. And we captured exciting new opportunities with customers who are global leaders in their industries. 

We’re proud of our performance. But it’s important to 
recognize that our achievements are not just the result 
of strong execution this year. Our success stems from our 
ongoing execution of the Strategy and Capital Allocation 
Framework that we introduced more than two years ago, 
the ability of our leaders to consistently take the long view 
of what’s best for Corning and all its stakeholders, and the 
dedication of our 46,000 global employees, who remain 
resilient during challenging times and always keep their 
eyes on the big picture.  

Our 2017 results confirm that we have the right strategy 
and talent in place to achieve the goals of our Framework 
and drive sustainable growth long term.

Financial Results
Before I review the key elements of the Strategy and Capital 
Allocation Framework, here’s a closer look at Corning’s 2017 
financial performance. 

Core sales were $10.5 billion, up 8 percent from 2016, while 
core earnings per share of $1.72 were up 11 percent year over 
year. All of Corning’s major businesses contributed to these 

outstanding results, with our Optical Communications 
and Specialty Materials segments having particularly 
strong years. Demand for carrier and enterprise products 
drove Optical Communications sales up 18 percent. 
Meanwhile, adoption of Corning® Gorilla® Glass 5 in the 
mobile consumer electronics market helped drive sales 
in our Specialty Materials segment up 25 percent.

The stock market has reflected the company’s strong 
performance. In 2017, Corning returned 35 percent, versus 
22 percent for the S&P 500 (both dividend adjusted). 

Those numbers, however, only tell part of the story. We are 
particularly excited about how strong execution against 
our Framework is positioning Corning for continued growth 
in the years ahead.

Strategy and Capital Allocation Framework
By now, you should be familiar with Corning’s Strategy and 
Capital Allocation Framework, but here’s a quick refresher. 
The Framework articulates Corning’s plan for leveraging its 
financial strength and focusing its portfolio to deliver value 
over the next several years.

We expect to generate and deploy $26 – $30 billion from 
2016 through 2019. We are investing $10 billion to grow 
and extend our leadership through a combination of 
research and development, capital spending, and strategic 
acquisitions. We are also returning more than $12.5 billion 
to our shareholders through share repurchases and annual 
dividend increases of at least 10 percent. 

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

Execution and Results
Since introducing the Framework in late 2015, we have 
distributed more than $9 billion to shareholders through 
share repurchases and increases to our quarterly 
dividend. Repurchases have reduced outstanding shares 
by approximately 30 percent. We increased the annual 
dividend 16.1 percent in February 2018, 14.8 percent in 2017, 
and 12.5 percent in 2016, for a combined increase of 
50 percent.

On the innovation front, we advanced key programs across 
our market-access platforms.
(cid:81) 

In Optical Communications, we celebrated a major 
milestone in September with the production of our one-
billionth kilometer of optical fiber. That’s approximately 
one third of the fiber ever produced worldwide, and 
enough to travel to the sun and back nearly three-
and-a-half times. We also continued our technology 
leadership with the introduction of a new multiuse 
platform to simplify installation and reduce the costs 
of deploying 4G and 5G networks.  
In Display, we began shipping the world’s first Gen 10.5 
LCD glass, and we continue to capture opportunities for 
our other display glass innovations. Samsung chose our 
Corning Lotus® NXT Glass for their flexible LTPS-OLED 
line, and Corning Iris™ Glass has helped enable Dell’s 
and Lenovo's new ultra-slim, ultra-bright monitors. 
In Mobile Consumer Electronics, we marked the 10th 
anniversary of Corning® Gorilla® Glass by winning 
new models, adding more of our glass to devices, and 
expanding into new applications. Gorilla Glass has now 
been used on more than five billion devices worldwide. 
The superior drop performance of Gorilla Glass 5 has 
enabled new smartphone designs that feature glass 
on both the front and back. And Gorilla Glass is now 
featured on approximately 75 percent of smartwatches.
In Automotive, we generated our first sales of gas 
particulate filters and secured an exclusive global 
supply agreement with Groupe PSA for the PureTech 
engine platform, which powers the latest models in the 
Peugeot and Citroën brands. We are also experiencing 
strong customer pull for Gorilla Glass for Automotive 
and have been awarded 35 platforms globally.
In Life Sciences Vessels, we launched Valor® Glass, a 
revolutionary new pharmaceutical packaging solution 
that dramatically reduces particle contamination, 
breaks, and cracks. As a result, Valor Glass helps 
protect patients, while increasing throughput for 
pharmaceutical manufacturers.

We supplemented these organic growth initiatives with 
strategic transactions to strengthen our portfolio. In July, 
we acquired SpiderCloud Wireless, Inc., a leading provider 
of in-building wireless solutions. Then in December, we 
announced our plans to acquire virtually all of 3M’s Commu-
nication Markets Division. These transactions strengthen 
our product portfolio, extend our global reach, and support 
our objective to grow annual sales in our Optical Communi-
cations segment to $5 billion by 2020.

To support our growth across multiple market-access plat-
forms, we are undertaking one of the largest expansions in 
Corning’s history. In 2017, we began adding capacity in North 
Carolina and Poland to help meet demand for optical com-
munications products. We are expanding manufacturing in 
China to produce Gen 10.5 LCD glass and support demand 
for gas particulate filters. We also announced the expansion 
of an existing plant in New York and the construction of a 
new high-volume manufacturing facility in North Carolina 
to produce Valor® Glass. Between 2017 and 2019, we expect 
to add, expand, or integrate more than 20 plants overall.

Delighting Our Customers
Perhaps the greatest measure of our success is the fact 
that other innovators are turning to us to help realize their 
own visions. In April, Verizon announced that they would 
be purchasing more than a billion dollars’ worth of our 
optical solutions to expand their coverage and enable next-
generation networks. In May, Apple announced a significant 
investment in our advanced glass manufacturing capabili-
ties in Harrodsburg, Kentucky, to produce next-generation 
mobile devices. And our July introduction of Valor Glass 
was made possible through close collaboration with Merck 
and Pfizer.

We continue to attract global leaders with our distinctive 
capabilities. We earn their trust through strong relation-
ships and close collaboration. And we delight them by 
producing unique solutions to tough challenges. Our track 
record leads to future opportunities for collaboration with 
existing customers, while also attracting other innovators 
in a broad range of industries. 

Opportunities Ahead
As we look to 2018 and beyond, here are some of the ways 
we are exploiting our distinctive capabilities to drive growth 
in both the near and long term.
(cid:81) 

In Optical Communications, we remain the only 
true end-to-end supplier of optical solutions, and we 
continue innovating for rapidly evolving applications, 
such as fiber to the home, hyperscale data centers, and 
in-building networks. We’re growing at more than twice 
the rate of the communications infrastructure market, 
and we are confident in our ability to reach $5 billion 
in annual sales by 2020, with further growth in the 
years ahead.  
In Display, we expect to maintain stable returns due to 
our strong share position, lowest-cost manufacturing, 
and the more favorable pricing environment. Simulta-
neously, we continue to leverage our fusion assets and 
other capabilities to drive the next round of display 
innovations ⎯ e.g., better images, ubiquitous touch, 
and new form factors. 
In Mobile Consumer Electronics, we continue making 
progress on our goal to double sales over the next 
several years by producing best-in-class products, 
capturing more real estate on mobile devices, winning 
share in new markets, and innovating for new product 
categories such as augmented reality.
In Automotive, Corning is benefiting from the industry’s 
trend toward cleaner, safer, and more connected vehicles. 
We expect sales of gas particulate filters to ramp 
quickly, driven by new regulations in Europe and China, 
and we believe this could be a $500 million business by 
early in the next decade. Meanwhile, more customers 
are recognizing the potential of Gorilla® Glass to reduce 
vehicle weight, increase fuel efficiency, add aesthetic 
appeal, and enable sophisticated interactive displays, 
thanks to events such as the 2017 Frankfurt Motor Show, 
which showcased Gorilla Glass on the Renault SYMBIOZ 
concept car.

Glass has the potential to power Corning’s growth for 
the next decade and beyond. 

Closing Thoughts
As we look ahead, we are confident in our ability to deliver 
on the goals of our Framework and continue doing what 
Corning does best ⎯ transforming industries, enhancing 
people’s lives, and delivering disruptive innovations that 
create value for decades. Our confidence is based not only 
on our outstanding 2017 results, but also on Corning’s 166-year 
track record. So I’d like to close by sharing my thoughts on 
what it takes to succeed for more than 165 years.

First, you need to focus on problems that matter. For example, 
we all want cleaner air to breathe. We all want medicines 
that are safe and effective. We all want fast, reliable access 
to information and communications networks that help us 
stay connected to our loved ones. And we all want devices 
that enhance our lives with style and performance, beauty 
and durability. Corning’s innovations are front and center 
for all these needs. By focusing on problems that matter, 
we ensure our ongoing relevance in a changing world. We 
activate the passion of our people, who care deeply about 
applying Corning’s distinctive skills to make the world a 
better place. And we maintain our focus and commitment 
during tough times and setbacks, because we know that 
we are doing important work that makes a real difference.

Second, you need a distinctive set of capabilities. At 
Corning, we are the best in the world at what we do, and 
we continue to enhance our knowledge and hone our skills 
so that we are always creating a better version of ourselves. 
Our distinctive capabilities make us vital to our customers. 
They make us increasingly relevant to new industries. 
And, because our capabilities are versatile and synergistic, 
they make it possible for us to evolve to meet the needs 
of changing markets. We don’t know exactly how all our 
products and markets will evolve in the decades to come, 
but we know that Corning will be there helping customers 
navigate their own transformations.  

Third, you need to maintain the trust of your stakeholders. 
We work hard every day to earn that trust with our 
performance and our actions. We live our values, honor 
our commitments, and communicate candidly about 
good news and bad.  

This formula has worked for us for more than 165 years, 
and we are confident that it will drive our success for 
the next 165 years. We hope you share our confidence in 
this strategy, our pride in Corning’s track record, and our 
excitement about the future. Thank you for being on this 
journey with us.  

Sincerely,

Wendell P. Weeks
Chairman, Chief Executive Officer, and President

Best-in-the-World Capabilities

Our cohesive portfolio allows us to capture synergies among our capabilities and reapply them 
to multiple market-access platforms. Here are some examples of those synergies in action.

Core Technologies

We use our Glass Science expertise to formulate glasses with the right optical, chemical, 
mechanical, and thermal properties for particular applications. This capability is at 
the heart of our industry-leading display and cover glass. We also use glass science to 
continually reinvent optical fiber. And today, we’re using our glass science expertise 
to make next-generation pharmaceutical packaging.  

Optical Physics refers to our ability to characterize and control the path of light. This 
capability has enabled our leadership in optical communications for more than four 
decades. We also leverage this capability for Corning Iris Glass, where the management 
of light distribution allows customers to design TVs that are just half a centimeter thick. 
In addition, we applied our optical physics expertise to create anti-reflective glass, which 
makes display screens much easier to read. 

Ceramic Science transforms inorganic, non-metallic materials into a broad range of 
objects and technologies. This capability is at the heart of our emissions-control products. 
Today, we’re also developing beautiful glass ceramics that create new design possibilities 
in mobile consumer electronics.

Manufacturing and Engineering Platforms

Our Vapor Deposition process makes glass so pure that if it replaced the water in the 
ocean, you could see the bottom clearly from any point on the surface. Vapor deposition 
is essential to make low-loss optical fiber. It’s also the foundation for high-purity fused 
silica, which enables stepper lenses that are used to fabricate small, power-efficient 
semiconductors for mobile devices. More recently, we applied this capability to create 
Gorilla Glass SR+ for wearable devices.

Our Fusion process allows us to make sheets of glass twice the size of a king-size bed, as 
thin as a business card, and flat to within 200 atoms. We use this platform to make our 
industry-leading display glass, as well as our tough, thin Gorilla Glass. We also leverage 
our fusion process to enable flexible OLED displays and create new interconnects for 
high-speed switches, routers, and servers.

We use our Precision Forming assets to make life sciences vessels that require an 
extremely high degree of accuracy, such as liquid-handling tools and cell-growth surfaces. 
We apply this same expertise to make optical connectors that align hair-thin fibers 
perfectly and eliminate the need for splices. Precision Forming is also enhancing the value 
proposition of Gorilla Glass for auto interior applications.

Corning’s expertise in Extrusion is why our cellular ceramic substrates can pack the 
surface area of a football field into an object the size of a soda can. We also use extrusion 
to make highly reliable and accurate pipettes for life sciences applications. And we’re 
leveraging this same expertise to make durable optical fiber cables for data centers.

We are constantly reapplying our knowledge and repurposing our assets across 
product sets and markets. These synergies increase our likelihood of success, reduce 
the cost of innovation, create higher barriers to entry for our competitors, and allow 
us to produce unique solutions that delight our customers. They also make it possible 
for us to evolve to meet the needs of changing markets.

Business Description

Corporate Investments

Dow Corning Corporation and Hemlock Semiconductor Group� Prior to 
May 31, 2016, Corning and The Dow Chemical Company (“Dow Chemical”) 
each  owned  half  of  Dow  Corning  Corporation  (“Dow  Corning”),  an 
equity company headquartered in Michigan that manufactures silicone 
products worldwide. Dow Corning was the majority-owner of Hemlock 
Semiconductor  Group  (“HSG”),  a  market  leader  in  the  production  of 
high  purity  polycrystalline  silicon  for  the  semiconductor  and  solar 
energy industries.

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

Prior  to  realignment,  HSG,  a  consolidated  subsidiary  of  Dow  Corning, 
was an indirect equity investment of Corning. Upon completion of the 
exchange, Corning now has a direct equity investment in HSG. Because 

our  ownership  percentage  in  HSG  did  not  change  as  a  result  of  the 
realignment,  the  investment  in  HSG  is  recorded  at  its  carrying  value, 
which had a negative carrying value of $383 million at the transaction 
date.  The  negative  carrying  value  resulted  from  a  one-time  charge  to 
this  entity  in  2014  for  the  permanent  abandonment  of  certain  assets. 
Excluding this charge, the entity is profitable and is expected to recover 
its equity in the near term.

Pittsburgh  Corning  Corporation�  Prior  to  the  second  quarter  of  2016, 
Corning  and  PPG  Industries,  Inc.  each  owned  50%  of  the  capital  stock 
of  Pittsburgh  Corning  Corporation  (“PCC”).  PCC  filed  for  Chapter  11 
reorganization  in  2000  and  the  Modified  Third  Amended  Plan  of 
Reorganization  for  PCC  (the “Plan”)  became  effective  in  April  2016.  In 
the  second  quarter  of  2016,  Corning  contributed  its  equity  interests 
in PCC and Pittsburgh Corning Europe N.V. as required by the Plan and 
recognized a gain of $56 million for the difference between the fair value 
of the asbestos litigation liability and carrying value of the investment.

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

Raw Materials

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

interruption in the event of specific materials shortages.

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

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.  Many  of  our  earlier  patents  have  now  expired,  but 
Corning continues to seek and obtain patents protecting its innovations. 
In 2017, Corning was granted about 560 patents in the U.S. and over 1,280 
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 2017, Corning and its wholly-
owned  subsidiaries  owned  over  10,900  unexpired  patents  in  various 
countries  of  which  over  4,560  were  U.S.  patents.  Between  2018  and 
2020, approximately 7% of these patents will expire, while at the same 
time Corning intends to seek patents protecting its newer innovations.

approximately $43 million for depreciation, maintenance, waste disposal 
and other operating expenses associated with pollution control. Corning 
believes that its compliance program does not place it at a competitive 
disadvantage.

Risk Factors

We  operate  in  rapidly  changing  economic,  political,  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,  our  ability  to  successfully 
execute our strategy and capital allocation framework, and the trading 
price  of  our  common  stock  or  debt.  The  following  discussion  of “risk 
factors”  identifies  the  most  significant  factors  that  may  adversely 
affect  our  business,  operations,  financial  position  or  future  financial 
performance.  This  information  should  be  read  in  conjunction  with 
MD&A  and  the  consolidated  financial  statements  and  related  notes 
incorporated  by  reference  into  this  report. The  following  discussion  of 

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 our forward-looking statements and from 
historical trends.

As a global company, we face many risks which could adversely impact 
our 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.

CORNING INCORPORATED - 2017 Annual ReportRisk Factors

Compliance with laws and regulations increases our costs. We are subject 
to  both  U.S.  laws  and  local  laws  which,  among  other  things,  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:

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

• 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;

• Governmental  protectionist  policies  and  sovereign  and  political  risks 

that may adversely affect Corning’s profitability and assets;

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

duties;

• Geographical  concentration  of  our  factories  and  operations,  and 

regional shifts in our customer base;

• Periodic health epidemic concerns;

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

governments, terrorism and the potential for other hostilities;

• Difficulty in protecting intellectual property, sensitive commercial and 

operations data, and information technology systems;

• Differing 

legal  systems, 

including  protection  and  treatment  of 

intellectual property and patents;

• Complex, or competing tax regimes;

• Difficulty in collecting obligations owed to us;

• Natural disasters such as floods, earthquakes, tsunamis and windstorms; 

and

• Potential loss of utilities or other disruption affecting manufacturing.

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

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

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

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

Business disruptions could affect our operating results

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

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

CORNING INCORPORATED - 2017 Annual Report 
Risk Factors

Geopolitical events, as well as other events outside of Corning’s control, 
could cause a disruption to our manufacturing operations and adversely 
impact  our  customers,  resulting  in  a  negative  impact  to  Corning’s  net 
sales, net income, asset values and liquidity

A  natural  disaster,  epidemic,  labor  strike,  war  or  political  unrest 
may  adversely  affect  Corning’s  ability  to  supply  our  customers  and 
impact  the  value  of  our  assets.  Such  events  may  also  impact  our 
customers’ facilities and reduce our sales to such customers. For example, 
a sizeable portion of Corning’s glass manufacturing capacity is located in 
South Korea and we generate a significant portion of our sales through 
two South Korean customers. Deterioration of the geopolitical climate in 
such a region could cause a disruption to our manufacturing operations 
and  adversely  impact  our  customers,  resulting  in  a  negative  impact  to 
Corning’s net sales, net income, asset values and liquidity.

measures and defenses in place against unauthorized access, but we may 
not be able to prevent, immediately detect, or remediate such events. A 
material breach in the security of our IT systems could include the theft 
of our intellectual property or trade secrets. Such disruptions or security 
breaches could result in the theft, unauthorized use or publication of our 
intellectual property and/or confidential business information, harm our 
competitive position, disrupt our manufacturing, reduce the value of our 
investment in research and development and other strategic initiatives, 
or otherwise adversely affect our business. 

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

We  may  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.

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

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

The  Company  is  dependent  on  information  technology  (“IT”)  systems 
and  infrastructure  for  its  business  and  manufacturing  controls.  Our  IT 
systems  may  be  vulnerable  to  disruptions  from  human  error,  outdated 
applications,  computer  viruses,  natural  disasters,  unauthorized  access, 
cyber-attack  and  other  similar  disruptions.  Any  significant  disruption, 
breakdown, intrusion, interruption or corruption of these systems or data 
breaches  could  cause  the  loss  of  data,  equipment  damage,  downtime, 
and/or  safety  related  issues  and  could  have  a  material  adverse  effect 
on  our  business.  Like  other  global  companies,  we  have,  from  time  to 
time,  experienced  incidents  related  to  our  IT  systems,  and  expect  that 
such  incidents  will  continue,  including  malware  and  computer  virus 
attacks, unauthorized access, systems failures and disruptions. We have 

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

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

We have significant exposure to foreign currency movements 

A large portion of our sales, profit and cash flows are transacted in non-
U.S. dollar currencies and we expect that we will continue to realize gains 
or  losses  with  respect  to  these  exposures.  We  will  experience  foreign 
currency  gains  and  losses  in  certain  instances  if  it  is  not  possible  or 
cost  effective  to  hedge  our  currency  exposures  or  should  we  elect  not 
to  hedge  certain  currency  exposures.  Alternatively,  we  may  experience 
gains  or  losses  if  the  underlying  exposure  which  we  have  hedged 
change  (increases  or  decreases)  and  we  are  unable  to  reverse,  unwind, 
or  terminate  the hedges concurrent with  the change in  the underlying 
notional exposure. 

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

Foreign  currency  movements  may  also  impact  our  competitive  cost 
position  relative  to  our  largest,  Japan-based  competitors  in  the  Display 
Technologies  segment.  The  profitability  of  customers  may  also  be 
impacted as they typically purchase from us in Japanese yen and they sell 
in various currencies.

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.

We have significant exposure to counterparties of our related derivatives 
portfolio 

We  maintain  a  significant  portfolio  of  over  the  counter  derivatives  to 
hedge our projected currency exposure to the Japanese yen, New Taiwan 
dollar,  South  Korean  won,  Chinese  yuan  and  euro.  We  are  exposed  to 
potential losses in  the event of non-performance by our counterparties 
to these derivative contracts. Any failure of a counterparty to pay on such 
a  contract  when  due  could  materially  impact  our  results  of  operations, 
financial position, and cash flows.

CORNING INCORPORATED - 2017 Annual ReportRisk Factors

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

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

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

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

At December 31, 2017, Corning had goodwill and other intangible assets 
of  approximately  $2.6  billion.  While  we  believe  the  estimates  and 
judgments  about  future  cash  flows  used  in  the  goodwill  impairment 
tests  are  reasonable,  we  cannot  provide  assurance  that  additional 
impairment  charges  in  the  future  will  not  be  required  if  the  expected 
cash  flow  estimates  as  projected  by  management  do  not  occur, 
especially if an economic recession occurs and continues for a lengthy 
period  or  becomes  severe,  or  if  acquisitions  and  investments  made  by 
the Company fail to achieve expected returns.

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

Our  effective  tax  rate  could  be  adversely 
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 laws, tax treaties and regulations or the interpretation 
of them, including the recent Tax Cuts and Jobs Act (the “2017 Tax Act”) 
passed by the U.S. Congress and signed into law on December 22, 2017;

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

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

administrative appeals;

• Changes  in  generally  accepted  accounting  principles  that  affect  the 

accounting for taxes; and

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

some jurisdictions.

We may have additional tax liabilities

We are subject to income taxes in the U.S. and many foreign jurisdictions 
and  are  commonly  audited  by  various  tax  authorities.  In  the  ordinary 
course  of  our  business,  there  are  many  transactions  and  calculations 
is  uncertain.  Significant 
where  the  ultimate  tax  determination 

10

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.

The  recent  2017  Tax  Act  could  significantly  impact  how  U.S.  global 
corporations are taxed. We are in the process of evaluating the impact 
of  this  new  legislation  and  certain  changes  could  have  a  material 
adverse impact on our tax expense and cash flow. Among other things, 
the 2017 Tax Act requires companies to pay a one-time mandatory tax 
on  unrepatriated  earnings  of  certain  foreign  subsidiaries  that  were 
previously  tax  deferred  (the  “toll  charge”)  and  creates  new  taxes 
on  certain  foreign  sourced  earnings.  The  toll  charge  resulted  in  an 
additional  $1.1  billion  provisional  tax  expense.  However,  settlement  of 
the  toll  charge  will  occur  almost  entirely  through  the  use  of  existing 
foreign tax credit carryovers of $1.1 billion.

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

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

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

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

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

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

CORNING INCORPORATED - 2017 Annual ReportLegal Proceedings

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

As  a  global  technology  and  manufacturing  company,  we  are  engaged 
in  various  litigation  and  regulatory  matters.  Litigation  and  regulatory 
proceedings  may  be  uncertain,  and  adverse  rulings  could  occur, 
resulting  in  significant  liabilities,  penalties  or  damages.  Such  current 
or future substantial legal liabilities or regulatory actions could have a 
material adverse effect on our business, financial condition, cash flows 
and reputation. 

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

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

In addition, the U.S. Foreign Corrupt Practices Act and similar foreign anti-
corruption laws generally prohibit companies and their intermediaries 
from  making  improper  payments  or  providing  anything  of  value  to 
improperly  influence  foreign  government  officials  for  the  purpose 

of  obtaining  or  retaining  business,  or  obtaining  an  unfair  advantage. 
Recent years have seen a substantial increase in the global enforcement 
of anti-corruption laws. Our continued operation and expansion outside 
the United States, including in developing countries, could increase the 
risk of alleged violations. Violations of  these laws may result in severe 
criminal or civil sanctions, could disrupt our business, and result in an 
adverse effect on our reputation, business and results of operations or 
financial condition.

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

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

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

Legal Proceedings

Environmental  Litigation�  Corning  has  been  named  by  the 
Environmental Protection Agency (the Agency) under the Superfund 
Act, or by state governments under similar state laws, as a potentially 
responsible  party  for  15  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,  2017 and 
December  31,  2016,  Corning  had  accrued  approximately  $38  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.

• New Accounting Standards

• Forward-Looking Statements

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

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

Performance against the Framework
Since  introducing  the  Framework,  we  have  distributed  $9  billion  to 
shareholders  through  share  repurchases  and  dividends,  and  increased 
the annual dividend by 16.1% in 2018, 14.8% in 2017 and 12.5% in 2016 as 
part of our ongoing commitment to return cash to our investors.

We also utilized our financial strength in 2017 to continue our focus on 
innovation, advancing key programs across our market platforms. Some 
of our achievements in 2017 included:

• Celebrating a major milestone with the production of our one billionth 
kilometer of optical fiber. We also continued our technology leadership 
with  the  introduction  of  a  new  multi-use  platform  to  simplify 
installation and reduce the costs of deploying 4G and 5G networks. 

• Shipping  the  world’s  first  Gen  10.5  glass.  In  addition,  we  captured 
new  opportunities  for  Corning  Iris™  Glass,  which  is  featured  in  new 
ultra-slim, ultra-bright lines of monitors.

• Expanding 

into  new  Corning®  Gorilla®  Glass  applications  and 
increasing  the  amount  of  our  glass  on  mobile  electronic  devices. 
Additionally,  the  superior  drop  performance  of  Gorilla  Glass  5  has 
enabled new smartphone designs that feature glass on both the front 
and back. 

• Securing  an  exclusive  global  supply  agreement  for  gas  particulate 
filters. We also won new customers for Gorilla Glass for Automotive, 
which is featured on thirty-five automotive platforms globally. 

• Launching  Valor®  Glass,  a  revolutionary  new  pharmaceutical 
packaging solution that dramatically reduces particle contamination, 
breaks,  and  cracks.  As  a  result,  Valor  helps  protect  patients,  while 
increasing manufacturing throughput. 

2017 Results
Net  sales  in  the  year  ended  December  31,  2017  were  $10,116  million, 
an  increase  of  $726  million,  or  8%,  when  compared  to  the  year 
ended  December  31,  2016.  The  increase  was  driven  by  the  Optical 
Communications  and  the  Specialty  Materials  segments,  up  $540 
million  and  $279  million,  respectively. The  Environmental Technologies 
and  Life  Sciences  segments  also  increased,  up  $74  million  and  $40 
million, respectively. A decline in net sales of $241 million in the Display 
Technologies  segment  partially  offset  these  increases,  driven  by  price 
declines of approximately 10%. 

For the year ended December 31, 2017, we generated a net loss of $497 
million, or $(0.66) per share, compared to net income of $3,695 million, 
or $3.23 per share, for 2016. When compared to last year, the $4.2 billion 
decrease  in  net  income  was  due  to  the  following  items  (amounts 
presented after tax): 

• The absence of a $2.7 billion non-taxable gain and $105 million positive 
tax adjustment on the strategic realignment of our ownership interest 
in Dow Corning recorded in the second quarter of 2016; 

• The impact of the passage of the 2017 Tax Act, including a provisional 
amount  related  to  the  one-time  mandatory  tax  on  unrepatriated 
foreign  earnings  of  $1.1  billion  and  a  provisional  amount  related  to 
the remeasurement of U.S. deferred  tax assets and liabilities of $347 
million;

• The  change  in  the  amounts  recorded  for  tax  law  changes,  valuation 
allowance adjustments and other discrete tax items in the amount of 
$186 million; 

• Higher  research,  development  and  engineering  expenses,  driven  by 
the absence of the impact of a 2016 joint development agreement in 
the Display Technologies segment, as well as higher costs associated 
with new product launches in the Optical Communications, Specialty 
Materials and Environmental Technologies segments; and

CORNING INCORPORATED - 2017 Annual Report

15

Management’s Discussion and Analysis of Financial Condition and Results of Operations

• A decrease of $104 million in net income in the Display Technologies 
segment, primarily driven by price declines of approximately 10%, the 
absence of a gain of $24 million recorded in 2016 from the contingent 
consideration  fair  value  adjustment  and  the  negative  impact  of 
movements in the Japanese yen and South Korean won in the amount 
of $59 million.

Partially offsetting these events were the following items:

• A decrease in unrealized losses from our translated earnings contracts 

in the amount of $162 million;

• Higher  net  income  in  the  Optical  Communications  segment,  up 

$96 million, driven by an 18% increase in net sales; 

• Higher net income in the Specialty Materials segment, up $75 million, 

driven by a 25% increase in net sales;

• The absence of a charge of $86 million related to the resolution of an 

investigation by the U.S. Department of Justice and related costs;

• Higher equity earnings of affiliated companies, driven by an increase 
of $90 million in equity earnings from HSG, offset somewhat by  the 
absence of $76 million in equity earnings from Dow Corning’s silicones 
business. The HSG increase was due to higher volume, which added $33 
million, and an increase of approximately $78 million in settlements of 
long-term  sales  agreements,  partially  offset  by  higher  restructuring 
and impairment charges of $17 million;

• A  decrease  in  restructuring,  impairment  and  other  charges,  largely 
due  to  the  absence  of  charges  incurred  in  2016  associated  with 
restructuring activity and the disposal of long-lived assets; and 

• Lower  acquisition-related  expenses,  down  $48  million,  driven  by  the 
absence of costs related to the realignment of our equity interests in 
Dow Corning completed in the second quarter of 2016, offset slightly 
by several small acquisitions occurring in 2017.

The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates, including the impact of hedges realized in 2017, did not materially 
impact Corning’s consolidated net income in the year ended December 
30, 2017 when compared to the year ended December 31, 2016.

2018 Corporate Outlook 
We believe 2018 will be another year of strong growth and investment, 
consistent  with  our  Strategy  and  Capital  Allocation  Framework,  and 
anticipate  that core sales will grow  to approximately $11 billion. In our 
Display Technologies segment, we expect pricing to continue to improve, 
with  year-over-year  declines  reaching  mid-single  digits,  an  important 
milestone toward our goal of stabilizing returns. We anticipate Corning’s 
LCD glass volume will grow faster than the expected LCD glass market 
growth of mid-single digits, driven by television screen size growth and 
the ramp of our Gen 10.5 facility in China. In the Optical Communications 
segment,  we  expect  sales  to  increase  by  about  10%,  excluding  any 
contribution  from  the  pending  acquisition  of  3M’s  Communications 
Market  Division,  driven  by  strong  demand  from  carrier  and  enterprise 
network  customers.  We  expect  high-single  digit  sales  growth  in  our 
Environmental Technologies  segment,  driven  by  continued  strength  in 
automotive  product  sales,  on-going  improvements  in  the  heavy-duty 
diesel market and from the commercial launch of gas-particulate filters. 
We expect growth in the Specialty Materials segment, the rate of which 
will depend on new model launches and the adoption of our innovations, 
and anticipate mid-single digit growth in the Life Sciences segment.

For the year ended December 31, 2017, net sales increased by $726 million, 
or  8%,  when  compared  to  the  same  period  in  2016. The  primary  sales 
drivers by segment were as follows:

• A decrease of $241 million in the Display Technologies segment, driven 
by price declines of approximately 10% and the negative impact from 
the  weakening  of  the  Japanese  yen  in  the  amount  of  $79  million, 
partially  offset  by  an  increase  in  volume  in  the  mid-single  digits  in 
percentage terms;

• An increase of $540 million in the Optical Communications segment, 
due  to  higher  sales  of  carrier  and  enterprise  network  products, 
up  $446  million  and  $94  million,  respectively,  combined  with  the 
absence  of  production  issues  related  to  the  implementation  of  new 
manufacturing  software  in  the  first  quarter  of  2016  and  the  impact 
of several small acquisitions completed in 2017. Strong growth in the 
North American market drove the increase in carrier network products;

• An increase of $74 million in the Environmental Technologies segment, 
driven by higher sales of automotive products, up $42 million, due to 
market strength in Europe, China and Asia, and initial commercial sales 
of  gas  particulate  filters.  Diesel  product  sales  increased  $32  million 
with higher demand for heavy-duty diesel products in North America 
and Asia;

• An increase of $279 million in the Specialty Materials segment, driven 
by strong growth in sales of Corning Gorilla Glass products, combined 
with an increase of $42 million in advanced optics products; 

• An  increase  of  $40  million  in  the  Life  Sciences  segment,  driven  by 

higher sales in North America and China; and

• An  increase  of  $34  million  in  the  All  Other  segment,  driven  by  an 

increase in sales in our emerging businesses.

Movements  in  foreign  exchange  rates  did  not  materially  impact 
Corning’s  consolidated  net  sales  in  the  year  ended  December  31,  2017, 
respectively, when compared to the same period in 2016.

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

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

• An  increase  of  $25  million  in  the  Optical  Communications  segment, 
driven primarily by an increase of $76 million in sales of carrier products 
and  the  impact  of  a  small  acquisition  completed  in  the  second 
quarter  of  2016,  partially  offset  by  production  issues  related  to  the 

implementation  of  new  manufacturing  software,  which  constrained 
our ability to manufacture product in the first half of 2016; 

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

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

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

volume growth in Europe, North America and China; and 

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

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

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

In 2017, 2016 and 2015, sales in international markets accounted for 69%, 
72% and 70%, respectively, of total net sales. 

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

Gross Margin 
In  the  year  ended  December  31,  2017,  gross  margin  dollars  increased 
by  $286  million,  or  8%,  and  gross  margin  as  a  percentage  of  net  sales 
remained  consistent  at  40%,  when  compared  to  the  same  period  last 
year. The  increase  in  gross  margin  dollars  was  primarily  driven  by  the 
following items:

• Higher  volume  in  the  Optical  Communications  segment,  driven 
by  growth  in  North  America  and  Europe,  partially  offset  by  higher 
manufacturing expenses related to capacity expansion; 

• An  increase  in  Gorilla  Glass  and  advanced  optics  product  volume, 

slightly offset by higher raw materials costs; and

17

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

• Higher light-duty substrate demand in Europe, China and Asia, offset 
somewhat  by  lower  North  America  demand,  as  well  as  an  increase 
in  demand  for  heavy-duty  diesel  products  in  North  America  and 
Asia.  Partially  offsetting  the  increase  in  demand  was  a  decline  in 
manufacturing efficiency due to the use of higher-cost manufacturing 
facilities and sales of lower margin products.

LCD glass price declines of approximately 10% and the negative impact 
of movements in the Japanese yen and South Korean won in the amount 
of  $73  million,  which  primarily  impacted  the  Display  Technologies 
segment, partially offset the increase.

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

Selling, General and Administrative Expenses 
When compared  to  the year ended December 31, 2016, selling, general 
and administrative expenses decreased by $5 million in the year ended 
December 31, 2017. The decrease was due to the following items:

• A  decrease  of  $52  million  in  acquisition-related  costs,  driven  by  the 
absence of costs related to the realignment of our equity interests in 
Dow Corning completed in the second quarter of 2016, offset slightly 
by several small acquisitions occurring in 2017;

• A  decrease  of  $64  million  in  litigation,  regulatory  and  other  legal 
costs,  primarily  driven  by  the  absence  of  events  occurring  in  the 
second  quarter  of  2016.  In  this  period,  we  recorded  litigation  and 
other expenses related to the resolution of an investigation by the U.S. 
Department of Justice and an environmental matter in the amount of 
$98 million, offset somewhat by  the gain on  the contribution of our 
equity interests in PCC and PCE as partial settlement of the asbestos 
litigation in the amount of $56 million; and

• A decrease of $46 million in the mark-to-market of our defined benefit 

pension plans.

Offsetting these events were the following items:

• A decrease of $32 million in gains from the contingent consideration 

fair value adjustment; 

• An increase of $51 million in the Optical Communications segment due 

to costs associated with acquisitions and growth initiatives; and

Partially offsetting these events were:

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

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

• Higher  operating  expenses 

in 

the  Optical  Communications, 

Environmental Technologies and Specialty Materials segments. 

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

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

Research, Development and Engineering 
Expenses 
In  the  year  ended  December  31,  2017,  research,  development  and 
engineering expenses increased by $118 million, or 16%, when compared 
to the same period last year, driven by the absence of the impact of a 2016 
joint development agreement in the Display Technologies segment, as 
well as higher costs associated with new product launches in the Optical 
Communications,  Specialty  Materials  and  Environmental Technologies 
segments,  up  $20  million,  $11  million  and  $7  million,  respectively.  As 
a  percentage  of  sales,  these  expenses  increased  one  percent  when 
compared to the same period last year. 

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

Restructuring, Impairment, and Other Charges 
Corning  recorded  restructuring,  impairment,  and  other  charges  and 
credits  in  2016  and  2015.  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:

• An  increase  of  $24  million  in  the  Specialty  Materials  segment  in 

support of new product launches.

2017 Activity

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

For  the  year  ended  December  31,  2017,  we  did  not  record  significant 
impairment  and  other  charges  or  reversals.  Cash 
restructuring, 
expenditures for restructuring activities were $4 million.  

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

defined benefit pension plans;

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

value adjustment of $43 million; and

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

in 2015.

2016 Activity

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

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

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

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

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

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

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

Refer to Note 14 (Commitments, Contingencies and Guarantees) to the 
consolidated financial statements for additional information.

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

Income Before Income Taxes
The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates,  including  the  impact  of  hedges  realized  in  2017,  did  not  impact 
Corning’s income before income taxes in the year ended December 31, 
2017 when compared to the same period in 2016.

The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates  positively  affected  Corning’s  income  before  income  taxes  in  the 
year  ended  December  31,  2016  in  the  amount  of  $304  million  when 
compared  to  2015. This  impact  was  partially  offset  by  the  decrease  in 
the realized gain from our foreign currency translation hedges related to 
translated earnings of $452 million.

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

(Provision) benefit for income taxes

Effective tax rate (benefit)

For  the  year  ended  December  31,  2017,  the  effective  income  tax  rate 
differed  from  the  U.S.  statutory  rate  of  35%  primarily  due  to  the 
following benefits:

• As a result of the 2017 Tax Act, a provisional tax expense of $1.1 billion 
for the one-time mandatory tax on uprepatriated earnings of certain 
foreign subsidiaries that were previously deferred (the “toll charge”);

• The result of a provisional tax expense recorded for the U.S. deferred 
tax assets and liabilities re-measured at the reduced rate of 21%; and

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

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

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

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

Corning’s  results  for  the  year  ending  December  31,  2017  included  a 
total  $2.2  billion  worldwide  tax  provision,  inclusive  of  tax  on  normal 
operations  and  the  impacts  of  the  2017 Tax  Act.  Given  the  significant 
complexity  of  the  2017  Tax  Act  and  anticipated  future  guidance  from 
the  U.  S.  Treasury,  the  Securities  and  Exchange  Commission  and  the 
Financial  Accounting  Standards  Board  (“FASB”)  related  to  the  2017 Tax 
Act, the Securities Exchange Commission has issued its Staff Accounting 
Bulletin 118 (“SAB 118”) to provide registrants additional time to analyze 
and report the effects of tax reform during the “measurement period”. 
Under SAB 118, the registrant is required to record those items where ASC 
740 analysis is complete; include reasonable estimates and label them

as provisional where ASC 740 analysis is incomplete; and if reasonable 
estimates cannot be made, record items under the previous tax law. The 
measurement period ends on the date the entity has obtained, prepared, 
and analyzed the information that was needed in order to complete the 
accounting requirements under ASC Topic 740 and is not to exceed 1 year.

In addition to SAB 118, the FASB has issued guidance regarding how to 
account for tax reform as well as a proposal to reclassify stranded tax 
costs  from  AOCI  to  retained  earnings.  Furthermore,  to  date,  the  U.S. 
Treasury  has  issued  Notice  2018-07  on  December  29,  2017  and  Notice 
2018-13 on January 19, 2018 with additional guidance on how to compute 
the toll charges. 

At December 31, 2017, we have not completed our accounting for the tax 
effects  of  the  enactment  of  the  2017 Tax  Act;  however,  we  have  made 
a reasonable estimate of  the effects on our U.S. deferred  tax balances 
in  the  amount  of  $347  million,  the  one-time  toll  charge  of  $1.1  billion 
and  the  impact  on  our  state  valuation  allowances  and  recorded  these 
as  provisional  amounts.  The  initial  accounting  is  incomplete  as  we 
need  additional  time  and  information  to  analyze  all  aspects  of  the 
newly enacted law and how it impacts our worldwide operations. The 
additional information that needs to be obtained, prepared or analyzed 
in  order  to  complete  the  accounting  requirements  includes  receiving 
further  guidance  from  the  tax  authorities;  additional  time  to  prepare 
basis calculations; post-enactment impacts, and further time to validate 
our assumptions.

We  re-measured  the  U.S.  deferred  tax  assets  and  liabilities  based  on 
the rates at which  they are expected  to reverse in  the future, which is 
generally  21%.  However,  we  are  still  analyzing  certain  aspects  of  the 
2017 Tax Act and refining our calculations, which could potentially affect 
the  measurement  of  these  balances  or  potentially  give  rise  to  new 
deferred  tax amounts. The provisional amount recorded related  to  the 
re-measurement of our deferred tax balances was $347 million.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

The  one-time  toll  charge  is  based  on  our  unrepatriated  earnings  of 
certain  foreign  subsidiaries  that  were  previously  deferred. This  charge 
resulted in an additional provisional tax expense amount of $1.1 billion. 
We  have  not  yet  completed  our  calculation  of  the  toll  charge.  This 
amount may change when we finalize the calculation of unrepatriated 
earnings  that  were  previously  deferred  from  U.S.  federal  taxation  and 
finalize the amounts held in cash or other specified assets. Settlement 
of the toll charge will occur almost entirely through the use of existing 
foreign tax credit carryovers.

Corning has not made sufficient progress on estimating the impact of 
tax reform on its assertion regarding its indefinitely reinvested foreign 
earnings  so  the  Company  will  continue  to  follow  its  historic  position 
while it continues to analyze this issue. As of December 31, 2017, Corning 
estimates that its unremitted foreign earnings were $16.9 billion. While 
Corning  is  not  changing  its  assertion  at  this  time,  the  Company  has 
distributed  approximately  $2  billion  in  January  2018  from  two  of  its 
foreign  subsidiaries  to  the  U.S.  parent  of  those  subsidiaries. There  are 
no  incremental  taxes  beyond  the  toll  charge  due  with  respect  to  this 
distribution of cash.

Under  its  historic  policy,  Corning  will  continue  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.

Corning’s accounting for the impact of the global intangible low-taxed 
income  (GILTI)  provisions  of  the  2017  Tax  Act  is  incomplete  and,  as  a 
result, it has not yet elected a policy to account for the GILTI provisions.

We will continue to monitor future guidance and to assess the impacts 
of the 2017 Tax Act.

It is reasonably possible that the amount of unrecognized tax benefits 
will change due to one or more of the following events during the next 
twelve months: audit activity, tax payments, or final decisions in matters 
that are the subject of controversy in various jurisdictions within which 
we operate. We believe we have provided adequate contingent reserves 
for  these  matters.  However,  if  upon  conclusion  of  these  matters,  the 
ultimate  determination  of  taxes  owed  is  for  an  amount  materially 
different than our current reserves, our overall tax expense and effective 
tax rate could be materially impacted in the period of adjustment. 

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

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

2017 vs. 2016

2016 vs. 2015

For  the  year  ended  December  31,  2017,  comprehensive  income 
decreased by $3.5 billion, when compared to the same period in 2016, 
driven  by  a  decrease  in  net  income  of  $4.2  billion  and  a  decrease  in 
unamortized  actuarial  gains  for  postretirement  benefit  plans.  The 
significant decrease in net income was largely driven by the absence 
of  a  $2.7  billion  non-taxable  gain  and  a  $105  million  positive  tax 
adjustment  on  the  strategic  realignment  of  our  ownership  interest 
in  Dow  Corning  recorded  in  the  second  quarter  of  2016,  combined 
with the impact of the passage of the 2017 Tax Act, which included a 
provisional  toll charge of $1.1 billion and a provisional charge of $347 
million  as  a  result  of  the  remeasurement  of  U.S.  deferred  tax  assets 
and  liabilities.  Our  unamortized  actuarial  gains  decreased  driven  by 
a  decrease  in  the  discount  rates  used  to  value  our  postretirement 
benefit obligations.

Partially  offsetting  these  decreases  was  an  increase  in  the  gain  on 
foreign currency translation adjustments in the amount of $850 million 
(after-tax), largely driven by the weakening of foreign currencies, most 
significantly  the South Korean won, Japanese yen and  the euro, which 
impacted  comprehensive  income  in  the  amounts  of  $420  million, 
$164 million and $115 million, respectively.

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

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

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

See  Note  13  (Employee  Retirement  Plans)  and  Note  17  (Shareholders’ 
Equity) to the Consolidated Financial Statements for additional details.

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  that  reporting 
core  performance  measures  provides  investors  greater  transparency 
to  the  information  used  by  our  management  team  to  make  financial 
and  operational  decisions.  Corning  has  adopted  the  use  of  constant 
currency  reporting  for  the  Japanese  yen  and  South  Korean  won,  and 
uses  an  internally  derived  yen-to-dollar  management  rate  of  ¥99  and 
won-to-dollar management rate of ₩1,100. The Company believes that 
the use of constant currency reporting allows investors  to understand 
our  results  without  the  volatility  of  currency  fluctuations,  and  reflects 
the  underlying  economics  of  the  translated  earnings  contracts  used 
to  mitigate  the  impact  of  changes  in  currency  exchange  rates  on  our 
earnings and cash flows. 

Net sales, equity in earnings of affiliated companies and net income are 
adjusted to exclude the impacts of changes in the Japanese yen and the 
South Korean won, gains and losses on our translated earnings contracts, 
acquisition-related  costs,  certain  discrete  tax  items,  restructuring 
and  restructuring-related  charges,  certain  litigation-related  expenses, 
pension  mark-to-market  adjustments  and  other  items  which  do 

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

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

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

Core  net  sales  increased  by  $804  million,  or  8%,  in  the  year  ended 
December 31, 2017  when compared  to  the same period in 2016, driven 
by  increases  in  the  Optical  Communications  and  Specialty  Materials 
segments.  Lower  core  net  sales  in  the  Display  Technologies  segment 
partially  offset  the  increase,  down  $162  million,  or  5%,  driven  by  LCD 
glass price declines of approximately 10%, partially offset by an increase 
in volume in the mid-single digits in percentage terms.

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

The translation impact from movements in foreign currency exchange 
rates,  excluding  the  Japanese  yen  and  South  Korean  won,  in  the  year 
ended  December  31,  2017  positively  impacted  core  net  sales  in  the 
amount  of  $12  million,  and  in  the  year  ended  December  31,  2016, 
negatively impacted core net sales in the amount of $39 million.

Core Earnings

2017 vs. 2016

In  the  year  ended  December  31,  2017,  we  generated  core  earnings  of 
$1,756  million  or  $1.72  per  share,  compared  to  core  earnings  generated 
in  the  year  ended  December  31,  2016  of  $1,774  million,  or  $1.55  per 
share. The  decrease  in  core  earnings  of  $18  million  was  driven  by  the 
following items: 

• The  absence  of  equity  earnings  of  $102  million  from  Dow  Corning’s 
silicones  business  due  to  our  2016  realignment  of  our  ownership 
interest in Dow Corning;

• A decrease of $62 million in the Display Technologies segment, driven 
by LCD glass price declines of approximately 10%, partially offset by an 
increase in volume in the mid-single digits in percentage terms;

• An increase in corporate project expenses and variable compensation 

of $29 million and $25 million, respectively.

The  decline  was  offset  by  an  increase  in  core  earnings  in  the  Optical 
Communications segment of $99 million, due to higher sales of carrier 
and  enterprise  network  products,  combined  with  the  absence  of  the 
production issues in the first half of 2016 related to the implementation 
of new software and an increase in the Specialty Materials segment of 
$61 million, driven by an increase in Corning Gorilla Glass and advanced 
optics products.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Although core net earnings decreased in  the year ended December 31, 
2017, core earnings per share increased $0.17 per share, driven by lower 
weighted average shares outstanding due to repurchases of our common 
stock in 2017.

volume  in  carrier  network  products,  the  favorable  translation  impact 
from  movements  in  foreign  currency  exchange  rates,  excluding  the 
Japanese yen and South Korean won, of $13 million and manufacturing 
efficiencies gained through cost reductions. 

2016 vs. 2015

In  the  year  ended  December  31,  2016,  we  generated  core  earnings  of 
$1,774  million,  or  $1.55  per  share,  compared  to  $1,882  million,  or  $1.40 
per  share, in  the  year ended December 31, 2015. The decrease was due 
to declines in the Display Technologies and Environmental Technologies 
segments. Slightly offsetting the decline was higher core earnings in the 
Optical Communications segment, up $16 million, driven by higher sales 

Included  in  core  earnings  for  the  years  ended  December  31,  2017,  2016 
and 2015 is net periodic pension expense in the amount of $49 million, 
$51  million  and  $62  million,  respectively,  which  excludes  the  annual 
pension mark-to-market adjustments. In the years ended December 31, 
2017, 2016 and 2015, the mark-to-market adjustments were a pre-tax loss 
of $21 million, $67 million and $165 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 in earnings of affiliated companies and core 
earnings are non-GAAP financial measures utilized by our management 
to analyze financial performance without the impact of items that are 
driven  by  general  economic  conditions  and  events  that  do  not  reflect 
the underlying fundamentals and trends in the Company’s operations.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Items Excluded from GAAP Measures

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

(1)  Constant-currency adjustments:

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

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

(2)  Translation gain on Japanese yen-denominated debt: The gain on the translation of our Yen-denominated debt to U.S. dollars.

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

period presented. 

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

deal costs.

(5)  Discrete tax items and other tax-related adjustments: This represents the removal of discrete adjustments (e.g. changes in judgment about the 

realizability of certain deferred tax assets) as well as other non-operational tax-related adjustments. 

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

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

(7)  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.

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

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

(9)  Adjustments related  to acquisitions: Includes fair value adjustments  to  the Corning Precision Materials indemnity asset related  to contingent 

consideration, post-combination expenses and other acquisition and disposal adjustments.

(10)  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.

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

Dow Corning. 

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

(13)  Adjustments to remove the impacts of the Tax Cuts and Job Act of 2017: Includes a provisional amount related to the one-time mandatory tax on 
unrepatriated foreign earnings, a provisional amount related to the remeasurement of U.S. deferred tax assets and liabilities, changes in valuation 
allowances as a result of the 2017 Tax Act, and adjustments for the elimination of excess foreign tax credits planning.

Reportable Segments

Our reportable segments are as follows:

• Display Technologies – manufactures glass substrates primarily for flat 

panel liquid crystal displays.

• Optical  Communications  –  manufactures  carrier  and  enterprise 

network components for the telecommunications industry.

• Environmental Technologies  –  manufactures  ceramic  substrates  and 

filters for automotive and diesel emission control applications. 

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

• Life  Sciences  –  manufactures  glass  and  plastic 

labware, 
equipment,  media  and  reagents  enabling  workflow  solutions  for 
scientific applications.

All  other  segments  that  do  not  meet  the  quantitative  threshold  for 
separate  reporting  have  been  grouped  as  “All  Other.”  This  group  is 
primarily comprised of  the results of  the pharmaceutical  technologies 
business  and  new  product  lines  and  development  projects,  as  well 
as  certain  corporate  investments  such  as  Eurokera  and  Keraglass 
equity affiliates.

We prepared the financial results for our reportable segments on a basis 
that is consistent with the manner in which we internally disaggregate 
financial  information  to  assist  in  making  internal  operating  decisions. 
We included the earnings of equity affiliates that are closely associated 
with our reportable segments in the respective segment’s net income. 
We  have  allocated  certain  common  expenses  among  our  reportable 
segments  differently  than  we  would  for  stand-alone  financial 
information prepared in accordance with GAAP. Our reportable segments 
include non-GAAP measures which are not prepared in accordance with 
GAAP. We believe investors should consider these non-GAAP measures in 
evaluating our results as they are more indicative of our core operating 
performance  and  how  management  evaluates  our  operational  results 
and  trends.  These  measures  are  not,  and  should  not  be  viewed  as  a 
substitute  for  GAAP  reporting  measures.  For  a  reconciliation  of  non-
GAAP  performance  measures  to  their  most  directly  comparable  GAAP 
financial  measure,  please  see “Reconciliation  of  Non-GAAP  Measures” 
above. Segment net income may not be consistent with measures used 
by other companies. The accounting policies of our reportable segments 
are the same as those applied in the consolidated financial statements.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

As Reported

2017 vs. 2016
Net sales decreased by $241 million, or 7%, in the year ended December 31, 
2017, when compared to the same period in 2016, driven by price declines 
of approximately 10% and the negative impact from the weakening of 
the  Japanese  yen  in  the  amount  of  $79  million,  partially  offset  by  an 
increase in volume in the mid-single digits in percentage terms. 

income  decreased  by  $104  million,  or  11%,  driven  by  the 

Net 
following items:

• The impact of price declines of approximately 10%; 

• The impact of the write-off of a net deferred tax asset of $38 million; 

• A reduction of $24 million in the gain on the fair value adjustment of 
the contingent consideration resulting from the acquisition of Corning 
Precision Materials; and

• An increase of $40 million in research, development and engineering 
expenses, primarily driven by the absence of the impact of a 2016 joint 
development agreement.

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

• A mid-single digit percentage increase in volume;

• Improvements in manufacturing efficiency, which added $68 million;

• An  increase  of  $42  million  in  the  realized  gain  from  our  yen  and 

won-denominated currency hedges; and

• A decrease in asset write-off expenses of $31 million.

The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates negatively impacted Display Technologies net income in the year 
ended December 31, 2017 in the amount of $59 million when compared 
to  the  same  period  in  2016.  This  impact  was  partially  offset  by  the 
increase in  the realized gain from our  translated earnings contracts in 
the amount of $42 million. 

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

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

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

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

denominated currency hedges; and

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

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

• A mid-single digit percentage increase in volume;

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

• Improvements in manufacturing efficiency; and

• A decline in operating expenses.

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

Core Performance

2017 vs. 2016
When compared to the same period in 2016, core net sales in the Display 
Technologies  segment  decreased  by  $162  million,  or  5%,  in  the  year 
ended December 31, 2017, driven by the price declines described above, 
partially offset by the increase in volume. Core earnings also decreased 
in  this period, down $62 million, or 6%, driven by price declines, offset 
somewhat by the increase in volume.

2016 vs. 2015
Core  net  sales  decreased  by  $218  million,  or  6%,  in  the  year  ended 
December 31, 2016 when compared  to  the same period in 2015, driven 
by  LCD  glass  price  declines  slightly  higher  than  10%,  partially  offset 
by  a  mid-single  digit  percentage  volume  increase.  Core  earnings  also 
decreased in  this period, down $69 million, or 6%, driven by LCD glass 
price declines slightly higher  than 10%, partially offset by a mid-single 
digit  percentage  volume  increase,  improvements  in  manufacturing 
efficiency and a decline in operating expenses.

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 2017, 2016 and 2015, three customers 
of the Display Technologies segment, which individually accounted for 
more  than  10%  of  segment  net  sales,  accounted  for  a  combined  62%, 
65% and 62% of total segment sales in those years. Our near-term sales 
and profitability would be impacted if any of these significant customers 
were unable to continue to purchase our products.

Corning has invested to expand capacity to meet the projected demand 
for LCD glass substrates. In 2017, 2016 and 2015, capital spending in this 
segment was $795 million, $464 million and $594 million, respectively. 

Outlook: 

For  full-year  2018,  Corning  expects  LCD  glass  market  growth  to  be  in 
the mid-single digit percentages, similar to 2017. The company expects 
Corning’s volume to grow faster than the market as Corning ramps up 
the world’s first Gen 10.5 fab in Hefei, China. We expect LCD glass pricing 
to continue to improve, with year-over-year declines reaching mid-single 
digits on a percentage basis, an important milestone toward our goal of 
stabilizing returns in this segment.

As Reported

2017 vs. 2016
Net  sales  increased  by  $540  million,  or  18%,  in  the  year  ended 
December 31, 2017, when compared to the same period in 2016, due to 
higher sales of carrier and enterprise network products, combined with 
the  absence  of  production  issues  related  to  the  implementation  of 
new manufacturing software in the first half of 2016 and the impact of 
several small acquisitions completed in the 2017. Strong growth in the 
North American fiber-to-the-home market drove the increase in carrier 
network products. 

Net income in the year ended December 31, 2017 increased by $96 million, 
or 39%, driven by the increase in sales described above and a decrease of 
$10 million in restructuring and asset write-off expenses, partially offset 
by capacity expansion spending and an increase in acquisition-related 
expenses. 

Movements in foreign currency exchange rates did not materially impact 
net sales or net income in this segment in the year ended December 31, 
2017 when compared to the same period in 2016.

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

income 

in  the  Optical  Communications  segment 

Net 
increased 
$8 million, or 3%, in the year ended December 31, 2016 when compared 
to the same period in 2015. The increase was driven by cost reductions 

and the continuation of the favorable shift toward sales of our solutions 
products,  partially  offset  by  the  impact  of  the  production  issues 
described above, costs incurred related to a small acquisition completed 
in  the  second  quarter  of  2016  and  restructuring  and  asset  write-off 
expenses. Movements in foreign exchange rates positively impacted net 
income in the amount of $12 million when compared to 2015.

Core Performance

2017 vs. 2016
Core  earnings  increased  in  the  year  ended  December  31,  2017  by 
$99  million,  or  33%,  driven  by  the  increase  in  sales  described  above, 
partially offset by capacity expansion spending. 

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

The  Optical  Communications  segment  has  a  concentrated  customer 
base. In the year ended December 31, 2017, one customer that individually 
accounted for more than 10% of segment net sales, accounted for 19% 
of  total  segment  net  sales.  In  the  year  ended  December  31,  2016,  one 
customer that individually accounted for more than 10% of segment net 
sales,  accounted  for  15%  of  total  segment  net  sales.  In  the  year  ended 
December 31, 2015, two customers that individually accounted for more 
than  10%  of  segment  net  sales,  accounted  for  22%  of  total  segment 
net sales. 

Outlook: 

Full-year 2018 Optical Communications sales are expected to increase by 
about 10% year over year, excluding any contribution from the pending 
acquisition of 3M’s Communications Markets Division.

Core Performance

2017 vs. 2016
Net  sales  increased  $74  million,  or  7%  in  the  year  ended  December  31, 
2017. Automotive product sales increased by $42 million, due to market 
strength in Europe, China and Asia, and initial commercial sales of gas 
particulate filters. Diesel product sales increased $32 million with higher 
demand for heavy-duty diesel products in North America and Asia. 

Net income in the year ended December 31, 2017 decreased by $6 million, 
or  5%,  driven  by  expenses  in  support  of  new  product  launches  and 
charges related to the disinvestment of an equity company.

Movements in foreign currency exchange rates did not materially impact 
net sales or net income in this segment in the year ended December 31, 
2017 when compared to the same period in 2016.

2016 vs. 2015
Net  sales  in  the  Environmental  Technologies  segment  decreased  by 
$21 million, or 2%, in the year ended December 31, 2016 when compared 
to the same period in 2015, driven by a decrease of $78 million in sales 
of diesel products due to the weakening of the heavy-duty diesel truck 
market in North America, offset partially by an increase of $57 million in 
light-duty  substrates  sales,  driven  by  strength  in  the  North  American, 
European and Chinese markets. 

Net  income  decreased  by  $28  million,  or  17%,  driven  by  lower  sales  of 
heavy-duty diesel products and our investment in capacity for our gas 
particulate filters. Movements in foreign exchange rates versus the U.S. 
dollar negatively impacted net sales and net income in this segment in 
the amounts of $22 million and $8 million, respectively, in the year ended 
December 31, 2016, when compared to the same period in 2015. 

2017 vs. 2016
In the year ended December 31, 2017, core earnings increased by $3 million, 
or  2%,  when  compared  to  the  same  period  in  2016,  driven  by  higher 
volume  in  both  automotive  and  diesel  products,  offset  by  expenses 
in  support  of  new  product  launches  and  a  decline  in  manufacturing 
efficiency  due  to  the  use  of  higher-cost  manufacturing  facilities  and 
sales of lower margin products.

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

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 
2017,  2016  and  2015,  net  sales  to  three  customers,  which  individually 
accounted for more than 10% of segment sales, accounted for 81%, 85% 
and  86%,  respectively,  of  total  segment  sales. While  we  are  not  aware 
of any significant customer credit issues with our direct customers, our 
near-term  sales  and  profitability  would  be  impacted  if  any  individual 
customers were unable to continue to purchase our products.

Outlook: 

For 2018, Environmental Technologies sales are expected to increase by a 
high-single digit percentage.

As Reported

2017 vs. 2016
Net sales in the Specialty Materials segment increased by $279 million, 
or 25%, in the year ended December 31, 2017, when compared to the same 
period in 2016, driven by an increase in sales of Gorilla Glass products 
in  support  of  new  product  launches,  combined  with  an  increase  in 
advanced optics products. 

Net  income  in  year  ended  December  31,  2017  increased  by  $75  million, 
or  43%,  when  compared  to  the  same  period  in  2016,  primarily  due  to 
the significant increase in net sales, lower restructuring charges and the 
absence of the costs associated with a power outage in Taiwan. 

Movements  in  foreign  currency  exchange  rates  did  not  materially 
impact  net  sales  or  net  income  in  this  segment  in  the  year  ended 
December 31, 2017 when compared to the same period in 2016.

2016 vs. 2015
Net sales in the Specialty Materials segment increased by $17 million, or 
2%, in the year ended December 31, 2016 when compared to the same 
period in 2015, driven by an increase in sales of Corning Gorilla Glass 5 
and  advanced  optics  products.  Although  Corning  Gorilla  Glass  sales 
were lower in the first three quarters of 2016, sales in the fourth quarter 
of 2016 increased approximately 22% over the same period last year, led 
by the rapid adoption of Corning Gorilla Glass 5. Net income increased 
by  $7  million,  or  4%,  driven  by  manufacturing  cost  reductions,  higher 
advanced optics sales and the impact of Gorilla Glass 5, offset slightly by 

higher research and development costs. Movements in foreign exchange 
rates did not materially impact net sales and net income in the Specialty 
Materials  segment  in  the  twelve  months  ended  December  31,  2016 
when compared to the same period in 2015.

Core Performance

2017 vs. 2016
Core  earnings  increased  by  $61  million,  or  32%,  in  the  year  ended 
December 31, 2017, driven primarily by  the increase in sales of Corning 
Gorilla  Glass  and  advanced  optics  products,  offset  slightly  by  higher 
selling and administrative costs. 

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

For  2017,  2016  and  2015,  three  customers  of  the  Specialty  Materials 
segment,  which  individually  accounted  for  more  than  10%  of  segment 
sales, accounted for 58%, 56% and 56%, respectively, of total segment sales.

Outlook: 

The company expects year-over-year sales growth for Specialty Materials 
in 2018, with the rate and pace dependent upon customer adoptions.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

As Reported

Core Performance

2017 vs. 2016
Net sales in the Life Sciences segment increased by $40 million, or 5%, in 
the year ended December 31, 2017, when compared  to  the same period 
in  2016,  driven  by  strong  performance  in  North  America  and  China, 
combined with a small acquisition completed in 2017.

Net  income  increased  by  $6  million,  or  10%,  in  the  year  ended 
December  31,  2017,  driven  by  an  increase  in  volume  and  lower  asset 
write-offs and exit costs, offset somewhat by higher raw materials costs. 
Movements in foreign exchange rates did not materially impact net sales 
or net income in this period when compared to the same period in the 
prior year.

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

2017 vs. 2016
In the year ended December 31, 2017, core earnings increased by $3 million, 
or  4%,  when  compared  to  the  same  period  last  year,  driven  by  higher 
volume, offset somewhat by higher raw materials costs.

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

For  2017,  2016  and  2015,  two  customers  in  the  Life  Sciences  segment, 
which  individually  accounted  for  more  than  10%  of  total  segment  net 
sales, collectively accounted for 47%, 46% and 46%, respectively, of total 
segment sales.

Outlook: 

For  full-year  2018,  sales  are  expected  to  grow  by  a  mid-single-digit 
percentage year over year. 

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 the pharmaceutical technologies business and new product lines and development projects, as well as certain corporate 
investments such as Eurokera and Keraglass equity affiliates.

2017 vs. 2016
Net  sales  of  this  segment  increased  by  $34  million,  or  22%,  in  the  year 
ended  December  31,  2017,  respectively,  when  compared  to  the  same 
period in 2016, driven by an increase in sales in our emerging businesses. 
The decrease in the net loss in the year ended December 31, 2017 reflects 
an  increase  of  $14  million  in  equity  earnings  and  the  absence  of  asset 
write-offs in emerging businesses recorded in the first quarter of 2016. 

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

Liquidity and Capital Resources

Financing and Capital Structure
The following items discuss Corning’s financing and changes in capital 
structure during 2017 and 2016:

In the fourth quarter of 2017, Corning issued $750 million of 4.375% senior 
unsecured notes that mature on November 15, 2057. The net proceeds of 
$743 million will be used for general corporate purposes. We can redeem 
these notes at any time, subject to certain terms and conditions.

2017

2016

In  the  third  quarter  of  2017,  Corning  issued  ¥78  billion  Japanese 
yen-denominated  debt  securities  in  tranches  of  7,  10  and  20  years. 
The  proceeds  from  these  notes  were  received  in  Japanese  yen  and 
immediately  converted  to  U.S.  dollars  on  the  date  of  issuance. The  net 
proceeds  received  in  U.S.  dollars,  after  deducting  offering  expenses, 
was  approximately  $700  million.  Payments  of  principal  and  interest  on 
the  notes  will  be  in  Japanese  yen,  or  should  yen  be  unavailable  due  to 
circumstances beyond Corning’s control, a U.S. dollar equivalent. 

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

CORNING INCORPORATED - 2017 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. The 
Company paid four quarterly dividends of $0.135 during the year ended 
December 31, 2016 and paid four quarterly dividends of $0.12 during the 
year ended December 31, 2015.

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

On February 6, 2018, Corning’s Board of Directors declared a 16.1% increase 
in  the  Company’s  quarterly  common  stock  dividend,  which  increased 
the quarterly dividend from $0.155 to $0.18 per share of common stock, 
beginning with the dividend to be paid in the first quarter of 2018. This 
increase marks the seventh dividend increase since October 2011. 

Fixed Rate Cumulative Convertible Preferred 
Stock, Series A 
Corning  has  2,300  outstanding  shares  of  Fixed  Rate  Cumulative 
Convertible Preferred Stock, Series A. 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, 2017, the Preferred Stock has not been converted, and none 
of the anti-dilution provisions have been triggered. 

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

As part of this investment, Corning and a Chinese customer have entered 
into a long-term supply agreement that commits the customer to the 
purchase of Gen 10.5 glass substrates from the Corning manufacturing 
facility  in  Hefei.  This  agreement  stipulates  that  the  customer  will 
provide a non-refundable cash deposit in the amount of approximately 
$400 million to Corning to secure rights to an amount of glass that is 
produced by Corning over  the next 10 years. Corning has collected  the 
full amount of this deposit, adjusted for foreign exchange movements, 
receiving  $185  million  of  this  deposit  in  2016  and  $197  million  in  2015. 
As glass is shipped to the customer, Corning will recognize revenue and 
issue credit memoranda to reduce the amount of the customer deposit 
liability,  which  are  applied  against  customer  receivables  resulting 
from  the  sale  of  glass.  In  2017,  2016  and  2015,  no  credit  memoranda 
were issued. 

Capital Spending
Capital spending totaled $1.8 billion in 2017, an increase of approximately 
$700  million  when  compared  to  2016,  driven  by  expansions  related 
to  the  Gen  10.5  glass  manufacturing  facility  in  China,  the  addition  of 
capacity  to  support  the  new  gas-particulate  filters  business  in  the 
Environmental  Technologies  segment,  fiber  and  cable  capacity  in  the 
Optical Communications segment and general business growth in the 
Specialty Materials segment. We expect our 2018 capital expenditures to 
be slightly more than $2 billion.

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

Net cash provided by operating activities

Net cash (used in) provided by investing activities

Net cash used in financing activities

2017 vs. 2016

Net cash provided by operating activities decreased by $533 million in 
the year ended December 31, 2017 when compared to the same period 
last year, driven by $501 million of unfavorable movements in working 
capital.  The  negative  impact  of  working  capital  changes  was  largely 
driven by an increase of $143 million in VAT receivables in Asia, a payment 
of $70 million related to our obligation under the plan of reorganization 
for PCC (refer to Note 2 (Commitments, Contingencies and Guarantees) 
to  the  consolidated  financial  statements  for  additional  information), 
an increase in accounts receivable and inventory to support growth in 
the Optical Communications, Environmental Technologies and Specialty 
Materials segments.

Net  cash  used  in  investing  activities  increased  by  $5.4  billion  in  the 
year ended December 31, 2017, when compared to the same period last 
year, driven by the absence of $4.8 billion of cash received in the second 
quarter  of  2016  on  the  realignment  of  Dow  Corning,  coupled  with  an 
increase of $674 million in capital expenditures largely due to capacity 
expansions  and  a  decline  of  $92  million  in  liquidations  of  short-term 
investments. A decline of $162 million in acquisition spending partially 
offset these events.

Net cash used in financing activities in the year ended December 31, 2017 
decreased by $3.7 billion when compared to the same period last year, 
driven by lower share repurchases, down $1.8 billion, proceeds from the 
issuance  of  long-term  debt  of  $1.4  billion,  the  absence  of  $481  million 
of commercial paper repayments made in 2016 and an increase of $171 
million in proceeds from the exercise of stock options.

2016 vs. 2015

Net cash provided by operating activities decreased $292 million in the 
year  ended  December  31,  2016  when  compared  to  2015,  driven  largely 
by  a  decrease  in  net  income  excluding  non-cash  gains,  an  increase  in 
accounts  receivable  in  the  Optical  Communications  and  Specialty 
Materials  segments,  up  $81  and  $70  respectively,  partially  offset  by  an 
increase  in  accounts  payable  and  other  current  liabilities.  A  decrease 
of $58 million in dividends received from equity affiliates, driven by the 
strategic  realignment  of  our  ownership  interest  in  Dow  Corning,  also 
negatively impacted cash flow from operations.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Net  cash  provided  by  investing  activities  increased  substantially,  up 
$4.3  billion,  in  the  year  ended  December  31,  2016  when  compared  to 
2015, driven by $4.8 billion in cash received upon the realignment of Dow 
Corning, a decrease of $120 million in capital expenditures and a decrease 
of $399 million in acquisition spending, partially offset by a decrease of 
$452 million in realized gains on our translated earnings contracts.

Net cash used in financing activities in the year ended December 31, 2016 
increased $2.7 billion when compared to 2015, driven by an increase of 
$999  million  in  share  repurchases,  the  repayment  of  $481  million  of 
commercial paper outstanding in 2015 and the absence of cash received 
from the issuance of long-term debt in the amount of $745 million in the 
third quarter of 2015.

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,  2017,  this  plan  accounted  for  77% 
of  our  consolidated  defined  benefit  pension  plans’  projected  benefit 
obligation and 85% of the related plans’ assets.

In  2017,  we  made  no  voluntary  cash  contributions  to  our  domestic 
defined  benefit  pension  plan  and  $29  million  to  our  international 
pension  plans.  In  2016,  we  made  voluntary  cash  contributions  of 

$73 million to our domestic defined benefit pension plan and $16 million 
to our international pension plans. Although we are not subject to any 
mandatory contributions in 2018, we anticipate making voluntary cash 
contributions of $105 million to our U.S. qualified pension plan and up to 
$27 million to our international pension plans in 2018.

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

Restructuring
For  the  year  ended  December  31,  2017,  we  did  not  record  significant 
restructuring, 
impairment  and  other  charges  or  reversals.  Cash 
expenditures for restructuring activities were approximately $4 million. 

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

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

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Management Assessment of Liquidity
We ended the fourth quarter of 2017 with approximately $4.3 billion of 
cash  and  cash  equivalents.  Our  cash  and  cash  equivalents  are  held  in 
various locations throughout the world and are generally unrestricted. 
We utilize a variety of strategies  to ensure  that our worldwide cash is 
available  in  the  locations  in  which  it  is  needed.  At  December  31,  2017, 
approximately 79% of the consolidated amount was held outside of the 
United States. In January 2018, the Company distributed approximately 
$2 billion from two of its foreign subsidiaries to the U.S. parent of those 
subsidiaries. There are no incremental taxes beyond the toll charge due 
with respect to this distribution of cash. 

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

Corning  also  has  a  commercial  paper  program  pursuant  to  which  we 
may issue short-term, unsecured commercial paper notes. In  the  third 
quarter  of  2016,  Corning’s  Board  of  Directors  approved  an  increase  to 
the  allowable  maximum  aggregate  principal  amount  outstanding  at 
any time from $1 billion to $2 billion. Under this program, the Company 
may  issue  the  paper  from  time  to  time  and  will  use  the  proceeds  for 
general  corporate  purposes.  The  Company’s  $2  billion  revolving  credit 
facility is available to support obligations under the commercial paper 
program, if needed. Corning did not have outstanding commercial paper 
at December 31, 2017.

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

During 2016, Corning repurchased 197.1 million shares for approximately 
$4.2  billion  through  an  accelerated  share  repurchase  agreement  and 
open  market  repurchases  as  part  of  the  2015  Repurchase  Programs.  In 
December 2016, Corning’s Board of Directors approved a $4 billion share 
repurchase program with no expiration (the “2016 Repurchase Program”). 

During 2017, Corning repurchased 84.4 million shares for approximately 
$2.4 billion through accelerated share repurchase agreements and open 
market repurchases under the 2016 Repurchase Program.

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

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

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

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,  2017,  our  leverage 
using  this  measure  was  25%  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, 2017, we were in compliance with 
all such provisions.

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

Translated Earnings Contracts
In the second quarter of 2013 and continuing throughout 2015, Corning 
entered into a series of zero cost average rate collars and average rate 
forwards to hedge the translation impact of Japanese yen on Corning’s 
projected 2015, 2016 and 2017 net income. Additionally, Corning extended 
its foreign exchange hedging program to hedge a significant portion of 
its projected yen exposure for the period 2018 through 2022, with average 
rate forwards, collars and puts. In the years ended December 31, 2017 and 
2016,  we  recorded  pre-tax  net  losses  of  $201  million  and  $459  million, 
and in the year ended December 31, 2015, we recorded a pre-tax net gain 
of $113 million related to changes in the fair value of these instruments. 
Included in these amounts are realized gains of $268 million, $207 million 
and $686 million, respectively. The gross notional value outstanding for 
these  instruments  which  hedge  our  exposure  to  the  Japanese  yen  at 
December 31, 2017, 2016 and 2015 was $13 billion, $14.9 billion and $8.3 
billion, respectively.

We  have  entered  into  zero-cost  collars  and  average  rate  forwards  to 
hedge  our  translation  exposure  resulting  from  movements  in  the 
South Korean won and its impact on our net income. In the years ended 
December 31, 2017 and 2016, we recorded pre-tax net gains of $95 million 
and $7 million, respectively, and  the year ended December 31, 2015, we 
recorded a pre-tax net loss of $36 million related to changes in the fair 
value of these instruments. Included in these amounts are realized losses 
of $1 million, $7 million and $33 million, respectively. These instruments 
had a gross notional value outstanding at December 31, 2017, 2016 and 
2015 of $0.8 billion, $1.2 billion and $3.3 billion, respectively. 

We  have  entered  into  a  portfolio  of  zero-cost  collars  and  average  rate 
forwards to hedge against our euro translation exposure. In the fourth 
quarter of 2016, the zero-cost collars expired. In the year ended December 
31 2017 we recorded a net pre-tax loss of $40 million, and in  the years 
ended December 31, 2016 and 2015, we recorded net pre-tax gains of $15 
million and $3 million, respectively. At December 31, 2017, 2016 and 2015, 
the  euro-denominated  average  rate  instruments  had  a  gross  notional 
amount of $0.3 billion.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

In 2016, we entered into a portfolio of average rate forwards  to hedge 
against  our  translation  exposure  resulting  from  movements  in  the 
Chinese  yuan.  In  the  year  ended  December  31  2017,  we  recorded  a  net 
pre-tax  gain  of  $27  million,  and  in  the  year  ended  December  31,  2016, 
we recorded a net pre-tax loss of $11 million related  to changes in  the 
fair  value  of  these  instruments.  At  December  31,  2017  and  2016,  the 
yuan-denominated average rate forwards had a gross notional amount 
of $0.2 billion and $0.3 billion, respectively. 

These derivative instruments are not designated as accounting hedges, 
and changes in their fair value are recorded in earnings in the translated 
earnings contract (loss) gain, net line of the Consolidated Statements of 
(Loss) Income. 

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

Corning’s off balance sheet arrangements include guarantee contracts. 
At the time a guarantee is issued, the Company is required to recognize 
a liability for the fair value or market value of the obligation it assumes. 
In  the  normal  course  of  our  business,  we  do  not  routinely  provide 

significant  third-party  guarantees.  Generally,  third-party  guarantees 
provided by Corning are limited to certain financial guarantees, including 
stand-by letters of credit and performance bonds, and the incurrence of 
contingent liabilities in the form of purchase price adjustments related 
to attainment of milestones. These guarantees have various terms, and 
none of these guarantees are individually significant.

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

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

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

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

(1)  At December 31, 2017, $39 million of the $75 million was included in other accrued liabilities on our consolidated balance sheets.

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

pay contracts.

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

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

(5)  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.

(6) At December 31, 2017, $54 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.

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

Environment

Corning has been named by the Environmental Protection Agency (the 
Agency) under the Superfund Act, or by state governments under similar 
state laws, as a potentially responsible party for 15 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, 
2017  and  December  31,  2016,  Corning  had  accrued  approximately  $38 
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. 

Critical Accounting Estimates

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

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

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

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

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

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

asset is being used or in its physical condition;

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

• An  accumulation  of  costs  significantly  in  excess  of  the  amount 

originally expected for the acquisition or construction of an asset;

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

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

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

For  long-lived  assets,  when  impairment  indicators  are  present,  we 
compare  estimated  undiscounted  future  cash  flows,  including  the 
eventual disposition of  the asset group at market value,  to  the assets’ 
carrying  value  to  determine  if  the  asset  group  is  recoverable.  This 
assessment  requires  the  exercise  of  judgment  in  assessing  the  future 
use of and projected value to be derived from the assets to be held and 
used. Assessments also consider changes in asset utilization, including 
the  temporary  idling  of  capacity  and  the  expected  timing  for  placing 
this  capacity  back  into  production.  If  there  is  an  impairment,  a  loss  is 
recorded  to  reflect  the  difference  between  the  assets’  fair  value  and 
carrying  value.  This  may  require  judgment  in  estimating  future  cash 
flows and relevant discount rates and residual values in estimating the 
current fair value of the impaired assets to be held and used.

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

38

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

At  December  31,  2017  and  December  31,  2016,  the  carrying  value  of 
precious  metals  was  higher  than  the  fair  market  value  by  $711  million 
and $890 million, respectively. The majority of these precious metals are 
utilized by the Display Technologies and Specialty Materials segments. 
Corning  believes  these  precious  metal  assets  to  be  recoverable  due  to 
the  significant  positive  cash  flow  in  both  segments. The  potential  for 
impairment exists in the future if negative events significantly decrease 
the  cash  flow  of  these  segments.  Such  events  include,  but  are  not 
limited to, a significant decrease in demand for products or a significant 
decrease  in  profitability  in  our  Display  Technologies  or  Specialty 
Materials segments.

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

Corning  adopted  ASU  2017-04,  Intangibles  –  Goodwill  and  Other,  on 
January  1,  2017,  which  simplifies  the  subsequent  measurement  of 
goodwill by removing the second step of the two-step impairment test. 
The  amendment  requires  an  entity  to  perform  its  annual,  or  interim 
goodwill impairment test by comparing the fair value of a reporting unit 
with its carrying amount. An impairment charge should be recognized 
for  the  amount  by  which  the  carrying  amount  exceeds  the  reporting 
unit’s fair value. 

Corning  has  recorded  goodwill  in  the  Display  Technologies,  Optical 
Communications,  Specialty  Materials,  Life  Sciences  and  All  Other 
operating  segments.  On  a  quarterly  basis,  or  if  an  event  occurs  or 
circumstances  change  that  indicate  the  carrying  amount  may  be 
impaired,  management  performs  a  qualitative  assessment  of  factors 
in  each  reporting  unit  within  these  operating  segments  to  determine 
if  there  have  been  any  triggering  events.  We  also  perform  a  detailed 
quantitative impairment test every three years if no indicators suggest 
a  test should be performed in  the interim.  We use  this calculation as 
quantitative validation of the qualitative process; this process does not 
represent  an  election  to  perform  the  quantitative  impairment  test  in 
place of the qualitative review.

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;

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 
quantitative goodwill impairment test.

Our  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. 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.

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 2017, 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 2017, 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.

• Overall financial performance, such as negative or declining cash flows 

or a decline in actual or forecasted revenue;

Specialty Materials

• 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.

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  2017,  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.

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

In addition to assessing qualitative factors each quarter, we performed 
a  quantitative  goodwill  recoverability  test  in  2015  for  this  reporting 
unit. A discount rate of 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.

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.

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 
2017, 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 2017, 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 tests in 2015. 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 

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  ASC 
Topic 740, Income Taxes, which requires that companies only record tax 
benefits for technical positions that are believed to 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.

At December 31, 2017, Corning has not completed its accounting for the 
tax  effects  of  the  enactment  of  the  2017 Tax  Act.  Pursuant  to  SAB  118, 
the Company has made a reasonable estimate of the effects on its U.S. 
deferred  tax  balances,  the  one-time  toll  charge  and  the  impact  on  its 
state valuation allowances. In addition, Corning has not made sufficient 
progress  on  estimating  the  impact  of  tax  reform  on  its  assertion 
regarding  its  indefinitely  reinvested  foreign  earnings  so  the  Company 
will continue to follow its historic position while it continues to analyze 
this issue. In addition, Corning’s accounting for the impact of the global 
intangible  low-taxed  income  (GILTI)  provisions  of  the  2017  Tax  Act  is 
incomplete and, as a result, it has not yet elected a policy to account for 
the GILTI provisions.

The  initial  accounting  is  incomplete  as  we  need  additional  time  and 
information  to  analyze  all  aspects  of  the  newly  enacted  law  and  how 
it  impacts  our  worldwide  operations. The  additional  information  that 
needs  to  be  obtained,  prepared  or  analyzed  in  order  to  complete  the 
accounting  requirements  includes  receiving  further  guidance  from 
the  tax authorities; additional  time  to prepare basis calculations; post 
enactment impacts and further time to validate of our assumptions.

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

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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

At December 31, 2017 and 2016, the carrying value of our equity method 
investment  assets  was  $280  million  and  $269  million,  respectively. 
In  addition,  we  also  have  an  equity  investment  (HSG)  with  a  negative 
carrying value of $105 million. The negative carrying value resulted from 
a one-time charge to this entity in 2014 for the permanent abandonment 
of  certain  assets.  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, 2017 and 
2016, we have not identified any instances where the carrying values of 
our equity method investments were not recoverable.

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

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

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

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

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

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

including 

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

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

CORNING INCORPORATED - 2017 Annual ReportManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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

Beginning with  the December 31, 2015 valuation of its defined benefit 
pension  and  OPEB  plans,  Corning  changed 
its  methodology  of 
determining  the  service  and  interest  cost  components  of  net  periodic 

pension  and  other  postretirement  benefit  costs  to  a  more  granular 
approach. Under the new approach, the cash flows from each applicable 
pension  and  OPEB  plan  are  used  to  directly  calculate  the  benefit 
obligation, service cost and interest cost using the spot rates from the 
applicable yield curve.

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

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

The 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, 2017, a 25 basis point decrease in each spot 
rate would decrease stockholders’ equity by $128 million before tax, and 
a 25 basis point increase in each spot rate would increase stockholders’ 
equity by $123 million. In addition, the impact of greater than a 25 basis 
point decrease in each spot rate would not be proportional to the first 25 
basis point decrease in each spot rate.

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

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

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

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

CORNING INCORPORATED - 2017 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  yuan,  and  the 
euro.  We  seek  to  mitigate  the  impact  of  exchange  rate  movements 
in  our  income  statement  by  using  over-the-counter  (OTC)  derivative 
instruments including foreign exchange forward and option contracts. 
In  general,  these  hedges  expire  coincident  with  the  timing  of  the 
underlying foreign currency commitments and transactions.

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

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

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,  2017, 
with  respect  to  open  foreign  exchange  forward  and  option  contracts, 

and  foreign  denominated  debt  with  values  exposed  to  exchange  rate 
movements,  a  10%  adverse  movement  in  quoted  foreign  currency 
exchange rates could result in a loss in fair value of these instruments of 
$1.4 billion compared to $1.6 billion at December 31, 2016. 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 $1,266 million 
compared to $1,458 million at December 31, 2016. 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 
$88 million compared to $79 million at December 31, 2016. The Company 
expects  that  these hypothetical losses from a 10% adverse movement 
in  quoted  foreign  currency  exchange  rates  on  the  derivative  financial 
instruments  should  largely  offset  gains  and  losses  on  the  assets, 
liabilities and future transactions being hedged. 

Because  we  derive  approximately  69%  of  our  net  sales  from  outside 
the  U.S.,  our  sales  and  net  income  could  be  affected  if  the  U.S.  dollar 
significantly  strengthens  or  weakens  against  foreign  currencies,  most 
notably the Japanese yen, South Korean won, and euro. As an example of 
the impact that changes in foreign currency exchange rates could have 
on our financial results, we compare 2017 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 2017 net sales of approximately $300 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 2017 net sales 
of approximately $6 million and $96 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 2017 net income attributable 
to  Corning  Incorporated  of  approximately  $187  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 2017 net income 
attributable to Corning Incorporated of approximately $63 million and 
$5 million, respectively.

Interest Rate Risk Management 
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 - 2017 Annual ReportManagement’s  Annual  Report  on  Internal  Control  Over 
Financial Reporting

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

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

Corning’s internal control over financial reporting is a process designed 
to  provide  reasonable  assurance  regarding  the  reliability  of  financial 
reporting  and  the  preparation  of  financial  statements  for  external 
purposes  in  accordance  with  accounting  principles  generally  accepted 
in the United States of America. Corning’s internal control over financial 
reporting  includes  those  policies  and  procedures  that  (i)  pertain  to 
the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and 
fairly  reflect  the  transactions  and  dispositions  of  Corning’s  assets; 
(ii)  provide  reasonable  assurance  that  transactions  are  recorded  as 

necessary to permit preparation of financial statements in accordance 
with  accounting  principles  generally  accepted  in  the  United  States  of 
America, and that Corning’s receipts and expenditures are being made 
only in accordance with authorizations of Corning’s management and 
directors;  and  (iii)  provide  reasonable  assurance  regarding  prevention 
or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition 
of  Corning’s  assets  that  could  have  a  material  effect  on  the  financial 
statements.  Because  of  its  inherent  limitations,  internal  control  over 
financial  reporting  may  not  prevent  or  detect  misstatements.  Also, 
projections  of  any  evaluation  of  effectiveness  to  future  periods  are 
subject  to  the  risk  that  controls  may  become  inadequate  because  of 
changes in conditions, or that the degree of compliance with the policies 
and procedures may deteriorate.

Management conducted an evaluation of the effectiveness of the system 
of internal control over financial reporting based on  the framework in 
Internal Control – Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. Management’s 
assessment of internal control over financial reporting includes controls 
over recognition of equity earnings and equity investments by Corning. 
Internal  control  over  financial  reporting  for  Hemlock  Semiconductor 
Group is the responsibility of its management. Based on this evaluation, 
management  concluded  that  Corning’s  internal  control  over  financial 
reporting  was  effective  as  of  December  31,  2017.  The  effectiveness  of 
Corning’s  internal  control  over  financial  reporting  as  of  December  31, 
2017, has been audited by PricewaterhouseCoopers LLP, an independent 
registered  public  accounting  firm,  as  stated  in  their  report  which  is 
included herein.

Opinions on the Financial Statements and Internal Control over

We  have  audited  the  accompanying  consolidated  balance  sheets  of

and  2016,  and  the  related  consolidated  statements  of  (loss)  income, 
comprehensive  income,  changes  in  shareholders’  equity  and  cash 
flows  for  each  of  the  three  years  in  the  period  ended  December  31, 
2017,  including  the  related  notes  and  schedule  of  valuation  accounts 
and reserves for each of the three years in the period ended December 
31,  2017  appearing  under  Item  15  (a)(2)  (collectively  referred  to  as 
the  “consolidated  financial  statements”).  We  also  have  audited  the 
Company’s  internal  control  over  financial  reporting  as  of  December 
31,  2017,  based  on  criteria  established  in  Internal  Control  -  Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO). 

In  our  opinion,  the  consolidated  financial  statements  referred  to 
above  present  fairly,  in  all  material  respects,  the  financial  position  of 
the  Company  as  of  December  31,  2017  and  2016,  and  the  results  of  its 
operations and its cash flows for each of the three years in the period 
ended  December  31,  2017  in  conformity  with  accounting  principles 
generally accepted in the United States of America. Also in our opinion, 
the  Company  maintained,  in  all  material  respects,  effective  internal 
control over financial reporting as of December 31, 2017, based on criteria 
established in Internal Control - Integrated Framework (2013) issued by 
the COSO.

Basis for Opinions

The  Company’s  management  is  responsible  for  these  consolidated 
financial  statements,  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  the 
Company’s  consolidated  financial  statements  and  on  the  Company’s 
internal control over financial reporting based on our audits. We are a 
public accounting firm registered with the Public Company Accounting 
Oversight  Board  (United  States)  (“PCAOB”)  and  are  required  to  be 
independent with respect to the Company in accordance with the U.S. 
federal securities laws and  the applicable rules and regulations of  the 
Securities and Exchange Commission and the PCAOB.

We  conducted  our  audits  in  accordance  with  the  standards  of  the 
PCAOB. Those standards require that we plan and perform the audits to 
obtain reasonable assurance about whether the consolidated financial 
statements are free of material misstatement, whether due to error or 
fraud,  and  whether  effective  internal  control  over  financial  reporting 
was maintained in all material respects. 

Our  audits  of  the  consolidated  financial  statements 
included 
performing  procedures  to  assess  the  risks  of  material  misstatement 
of  the  consolidated  financial  statements,  whether  due  to  error  or 
fraud,  and  performing  procedures  that  respond  to  those  risks.  Such 
procedures  included  examining,  on  a  test  basis,  evidence  regarding 
the amounts and disclosures in the consolidated financial statements. 
Our  audits  also  included  evaluating  the  accounting  principles  used 
and significant estimates made by management, as well as evaluating 
the  overall  presentation  of  the  consolidated  financial  statements.  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.

Definition and Limitations of Internal Control over 
Financial Reporting

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 - 2017 Annual ReportNotes to Consolidated Financial Statements

Corning Incorporated and Subsidiary Companies

1.  Summary of Significant Accounting Policies

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

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

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

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

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

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

Dow Corning
Prior  to  May  31,  2016,  Corning  and  Dow  Chemical  each  owned  half 
of  Dow  Corning,  an  equity  company  headquartered  in  Michigan 
that  manufactures  silicone  products  worldwide.  Dow  Corning  was 
the  majority-owner  of  HSG,  a  market  leader  in  the  production  of 
high  purity  polycrystalline  silicon  for  the  semiconductor  and  solar 
energy  industries.  On  May  31,  2016,  Corning  completed  the  strategic 
realignment  of  its  equity  investment  in  Dow  Corning  pursuant  to  the 
Transaction Agreement announced in December 2015. Under the terms 

of  the  Transaction  Agreement,  Corning  exchanged  with  Dow  Corning 
its 50% stock interest in Dow Corning for 100% of the stock of a newly 
formed entity, which holds an equity interest in HSG and approximately 
$4.8 billion in cash. Prior to realignment, HSG, a consolidated subsidiary 
of  Dow  Corning,  was  an  indirect  equity  investment  of  Corning.  Upon 
completion of the exchange, Corning now has a direct equity investment 
in HSG.

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

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

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

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

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

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

Research and Development Costs
Research  and  development  costs  are  charged  to  expense  as  incurred. 
Research  and  development  costs  totaled  $689  million 
in  2017, 
$637 million in 2016 and $638 million in 2015.

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. 
We  recorded  foreign  currency  transaction  gains  of  $20  million  and 
$21 million for the years ended December 31, 2017 and 2016, respectively, 
and foreign currency transaction losses of $22 million for the year ended 
December 31, 2015. These amounts were recorded in the line item Other 
expense, net in the Consolidated Statements of (Loss) Income.

Foreign  subsidiary  functional  currency  balance  sheet  accounts  are 
translated  at  current  exchange  rates,  and  statement  of  operations 
accounts  are  translated  at  average  exchange  rates  for  the  year. 
Translation  gains  and  losses  are  recorded  as  a  separate  component  of 

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

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

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

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

and equipment, net of accumulated depreciation, in 2017, 2016 and 2015, respectively.

Allowance for Doubtful Accounts
The  Company’s  allowance  for  doubtful  accounts  is  determined  based 
on  a  variety  of  factors  that  affect  the  potential  collectability  of  the 
related  receivables,  including  length  of  time  receivables  are  past  due, 
customer  credit  ratings,  financial  stability  of  customers,  specific  one-
time  events  and  past  customer  history.  In  addition,  in  circumstances 
where the Company is made aware of a specific customer’s inability to 
meet  its  financial  obligations,  a  specific  allowance  is  established.  The 
majority  of  accounts  are  individually  evaluated  on  a  regular  basis  and 
appropriate  reserves  are  established  as  deemed  appropriate  based  on 
the above criteria.

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  potentially  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.

53

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

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 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.

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  that  the carrying amount may be impaired. Corning also 
performs a detailed quantitative impairment test every three years if no 
indicators  suggest  a  test  should  be  performed  in  the  interim. We  use 
this  calculation  as  quantitative  validation  of  the  qualitative  process; 
this process does not represent an election to perform the quantitative 
impairment test in place of the qualitative 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 quantitative impairment 
analysis,  our  valuation  method  is  an  “income  approach”  using  a 

discounted  cash  flow  model  in  which  cash  flows  anticipated  over 
several  periods,  plus  a  terminal  value  at  the  end  of  that  time  horizon, 
are discounted to their present value using an appropriate rate of return. 
Our  estimates  are  based  upon  our  historical  experience,  our  current 
knowledge  from  our  commercial  relationships,  and  available  external 
information about future trends. If the fair value is less than the carrying 
value, a loss is recorded to reflect the difference between the fair value 
and carrying value.

intangible  assets 

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

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

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

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

54

CORNING INCORPORATED - 2017 Annual Report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.

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 (Loss) 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.

At  December  31,  2017,  Corning  has  not  completed  its  accounting  for 
the  tax  effects  of  the  enactment  of  the  2017 Tax  Act.  Pursuant  to  SAB 
118,  the  Company  has  made  a  reasonable  estimate  of  the  effects  on 
its U.S. deferred tax balances, the one-time toll charge and the impact 
on  its  state  valuation  allowances.  In  addition,  Corning  has  not  made 
sufficient  progress  on  estimating  the  impact  of  tax  reform  on  its 
assertion  regarding  its  indefinitely  reinvested  foreign  earnings  so  the 
Company will continue to follow its historic position while it continues 
to  analyze  this  issue.  In  addition,  Corning’s  accounting  for  the  impact 
of the global intangible low-taxed income (GILTI) provisions of the 2017 
Tax Act is incomplete and, as a result, it has not yet elected a policy to 
account for the GILTI provisions. The initial accounting is incomplete as 
we need additional time and information to analyze all aspects of the 
newly enacted law and how it impacts our worldwide operations. The 
additional information that needs to be obtained, prepared or analyzed 
in  order  to  complete  the  accounting  requirements  includes  receiving 
further  guidance  from  the  tax  authorities;  additional  time  to  prepare 
basis calculations; post enactment impacts and further time to validate 
of our assumptions.

Notes to Consolidated Financial Statements

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

• Absence of our ability to recover the carrying amount;

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

would justify the carrying amount of the investment; and

• Significant 

litigation,  bankruptcy  or  other  events  that  could 

impact recoverability.

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

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

Fair  value  is  the  price  that  would  be  received  from  selling  an  asset  or 
paid  to  transfer  a  liability  in  an  orderly  transaction  between  market 
participants at the measurement date. When determining the fair value 
measurements for assets and liabilities required  to be recorded at fair 
value, we consider the principal or most advantageous market in which 
we would transact and consider assumptions that market participants 
would  use  when  pricing  the  asset  or  liability,  such  as  inherent  risk, 
transfer restrictions, and risk of nonperformance.

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

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

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

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

One  of  Corning’s  equity  affiliates  is  currently  assessing  the  potential 
impact  of  adopting  ASU  2014-09  on  its  financial  statements  and  will 
adopt  the  standard  on  January  1,  2019.  Preliminary  analysis  indicates 
that the impact of adoption will not have a material impact on Corning’s 
financial statements.

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

One  of  Corning’s  equity  affiliates  is  currently  assessing  the  potential 
impact of adopting ASU 2016-02 on its financial statements and elected 
to adopt the standard on January 1, 2020.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows 
(Topic 230): Classification of Certain Cash Receipts and Cash Payments. 
ASU  2016-15  refines  how  companies  classify  certain  aspects  of  the 
cash  flow  statement  in  regards  to  debt  prepayment,  settlement  of 
debt  instruments,  contingent  consideration  payments,  proceeds  from 
insurance  claims  and  life  insurance  policies,  distribution  from  equity 
method investees, beneficial interests in securitization transactions and 
separately  identifiable  cash  flows.  ASU  2016-15  is  effective  for  annual 
periods  beginning  after  December  15,  2017,  and  for  interim  periods 
within  those fiscal years. We have determined  that  the  impact of  this 
standard will not be material. We will adopt this standard in 2018.

In  October  2016,  the  FASB  issued  ASU  No.  2016-16,  Income  Taxes 
(Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which 
reduces  the  complexity  in  the  accounting  standards  by  allowing  the 
recognition of current and deferred income taxes for an intra-entity asset 
transfer,  other  than  inventory,  when  the  transfer  occurs.  Historically, 
recognition  of  the  income  tax  consequence  was  not  recognized  until 
the  asset  was  sold  to  an  outside  party.  This  amendment  should  be 
applied on a modified retrospective basis  through a cumulative-effect 
adjustment  directly  to  retained  earnings  as  of  the  beginning  of  the 
period of adoption. ASU 2016-16 is effective for annual periods beginning 
after December 15, 2017, including interim reporting periods within those 
annual  reporting  periods.  Early  adoption  is  permitted  for  all  entities 
as  of  the  beginning  of  an  annual  reporting  period  for  which  financial 
statements (interim or annual) have not been issued or made available 
for issuance. That is, earlier adoption should be in the first interim period 
if  an  entity  issues  interim  financial  statements.  We  have  determined 
that the impact of this standard will not be material. We will adopt this 
standard in 2018.

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

In  March  2017,  the  FASB  issued  ASU  No.  2017-07,  Compensation—
Retirement  Benefits  (Topic  715):  Improving  the  Presentation  of  Net 
Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU 
2017-07  requires  entities  to  (1)  disaggregate  the  current-service-cost 
component from the other components of net benefit cost (the “other 
components”) and present it with other current compensation costs for 
related  employees  in  the  income  statement  and  (2)  present  the  other 
components elsewhere in the income statement and outside of income 
from  operations  if  that  subtotal  is  presented.  In  addition,  the  ASU 
requires entities to disclose the income statement lines that contain the 
other components if they are not presented on appropriately described 
separate lines. The amendment should be applied retrospectively for the 
presentation  of  the  service  cost  component  and  prospectively  for  the 
capitalization of the service cost component. ASU 2017-07 is effective for 
fiscal years beginning after December 15, 2017, including interim periods 
within  those fiscal years. Early adoption is permitted at  the beginning 
of  any  annual  period  for  which  an  entity’s  financial  statements  have 
not  been  issued  or  made  available  for  issuance. We  have  determined 
that the impact of this standard will not be material. We will adopt this 
standard in 2018.

not significant.

At  December  31,  2016  and  2015,  the  Company  held 
long-term 
investments of $29 million and $33 million, respectively. The Company’s 
investments in available-for-sale securities were held at fair value with 
amortized cost of $32 million and $37 million at December 31, 2016 and 
2015, respectively.

At  December  31,  2017,  Corning  did  not  hold  long-term  investments  or 
available-for-sale securities.

Proceeds from sales and maturities of short-term investments  totaled 
$29 million, $121 million and $1.6 billion in 2017, 2016 and 2015, respectively.

4.  Significant Customers

For  2017, no customers  met or exceeded 10% of Corning’s consolidated net sales. For 2016 and 2015, Corning’s sales  to Samsung Display Co. Ltd., a

Corning’s  results  for  the  year  ending  December  31,  2017  included  a 
total  $2.2  billion  worldwide  tax  provision,  inclusive  of  tax  on  normal 
operations  and  the  impacts  of  the  2017 Tax  Act.  Given  the  significant 
complexity of the 2017 Tax Act and anticipated future guidance from the 
U. S. Treasury, the Securities and Exchange Commission and the Financial 
Accounting  Standards  Board  (“FASB”)  related  to  the  2017  Tax  Act,  the 
Securities Exchange Commission has issued its Staff Accounting Bulletin 
118  (“SAB  118”)  to  provide  registrants  additional  time  to  analyze  and 
report the effects of tax reform during the “measurement period”. Under 
SAB 118, the registrant is required to record those items where ASC 740 
analysis  is  complete;  include  reasonable  estimates  and  label  them  as 
provisional  where  ASC  740  analysis  is  incomplete;  and  if  reasonable 
estimates cannot be made, record items under the previous tax law. The 
measurement period ends on the date the entity has obtained, prepared, 
and analyzed the information that was needed in order to complete the 
accounting requirements under ASC Topic 740 and is not to exceed 1 year.

In addition to SAB 118, the FASB has issued some guidance regarding how 
to  account  for  tax  reform  as  well  as  a  proposal  to  reclassify  stranded 
tax costs from AOCI to retained earnings. Furthermore, to date, the U.S. 
Treasury  has  issued  Notice  2018-07  on  December  29,  2017  and  Notice 
2018-13 on January 19, 2018 with additional guidance on how to compute 
the toll charges.

At December 31, 2017, we have not completed our accounting for the tax 
effects of the enactment of the 2017 Tax Act; however, we have made a 
reasonable estimate of the effects on our U.S. deferred tax balances, the 
one-time toll charge and the impact on our state valuation allowances. 
We recognized provisional amounts which are included as a component 
of income tax expense from continuing operations. The initial accounting 
is incomplete as we need additional time and information to analyze all 
aspects  of  the  newly  enacted  law  and  how  it  impacts  our  worldwide 
operations.  The  additional  information  that  needs  to  be  obtained, 
prepared or analyzed in order to complete the accounting requirements 
includes receiving further guidance from the tax authorities; additional 
time to prepare basis calculations; post-enactment impacts, and further 
time to validate our assumptions.

We  re-measured  the  U.S.  deferred  tax  assets  and  liabilities  based  on 
the rates at which  they are expected  to reverse in  the future, which is 
generally  21%.  However,  we  are  still  analyzing  certain  aspects  of  the 
2017 Tax Act and refining our calculations, which could potentially affect 
the  measurement  of  these  balances  or  potentially  give  rise  to  new 
deferred  tax amounts. The provisional amount recorded related  to  the 
re-measurement of our deferred tax balances was $347 million.

58

CORNING INCORPORATED - 2017 Annual ReportThe  one-time  toll  charge  is  based  on  our  unrepatriated  earnings  of 
certain  foreign  subsidiaries  that  were  previously  deferred. This  charge 
resulted in an additional provisional tax expense amount of $1.1 billion. 
We  have  not  yet  completed  our  calculation  of  the  toll  charge.  This 
amount may change when we finalize the calculation of unrepatriated 
earnings  that  were  previously  deferred  from  U.S.  federal  taxation  and 
finalize the amounts held in cash or other specified assets. Settlement 
of the toll charge will occur almost entirely through the use of existing 
foreign tax credit carryovers.

Corning  has  not  made  sufficient  progress  on  estimating  the  impact  of 
tax  reform  on  its  assertion  regarding  its  indefinitely  reinvested  foreign 
earnings so the Company will continue to follow its historic position while 
it continues to analyze this item. As of December 31, 2017, Corning estimates 
that  its  unremitted  foreign  earnings  were  $16.9  billion.  While  Corning 
is  not  changing  its  assertion  at  this  time,  the  Company  has  distributed 
approximately $2 billion in January 2018 from two of its foreign subsidiaries 
to  the  U.S.  parent  of  those  subsidiaries.  There  are  no  incremental  taxes 
beyond the toll charge due with respect to this distribution of cash.

Under  its  historic  policy,  Corning  will  continue  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 

Notes to Consolidated Financial Statements

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.

Corning’s accounting for the impact of the global intangible low-taxed 
income  (GILTI)  provisions  of  the  2017  Tax  Act  is  incomplete  and,  as  a 
result, it has not yet elected a policy to account for the GILTI provisions.

We  will  continue  to  monitor  for  future  guidance  and  to  assess  the 
impacts of the 2017 Tax Act.

Tax  benefit  associated  with  rate  differences  on  foreign  earnings  is 
primarily  the  income  of  subsidiaries  with  lower  statutory  rates  than 
the  U.S.  for  2017  and  for  2016  and  2015  includes  the  benefit  of  excess 
foreign  tax  credits  resulting  from  the  inclusion  of  foreign  earnings  in 
U.S. income.

During  2016,  a  realignment  of  Dow  Corning  interest  took  place.  Refer 
to  Note  7  (Investments)  of  the  Consolidated  Financial  Statements  for 
additional detail.

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

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.  The  amount  of  U.S.  and  foreign  deferred  tax  assets  that  have 
remaining  valuation  allowances  at  December  31,  2017  and  2016  was 
$456 million and $270 million, respectively.

The  2017  Tax  Act  makes  the  following  key  changes  to  U.S.  tax  law 
which  will  potentially  impact  Corning’s  deferred  tax  assets.  Corporate 
alternative minimum  tax (“AMT”) has been eliminated. Taxpayers with 

AMT  credit  carryovers  can  use  credits  to  offset  regular  tax  liability 
for  any  tax  year  or  such  credits  will  be  fully  refundable  by  year  2022. 
Corning has $28 million of AMT carryover. Net operating losses (“NOL’s”) 
generated prior to the 2017 Tax Act may still be carried back two years 
and forward 20 years. Corning has $34 million of Federal NOL’s that are 
subject  to  these  provisions. The  2017 Tax  Act  limits  and  in  some  cases 
eliminates  foreign  tax  credits.  Corning  has  $49  million  of  foreign  tax 
credit carryforwards that may be subject to these restrictions.

In  2017,  we  adopted  ASU  2016-09,  Improvements  to  Employee  Share-
Based  Payment  Accounting.  As  a  result,  cumulative  tax  benefits 
totaling  $233  million  were  recorded  as  an  adjustment  to  beginning 
retained earnings.

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

and  $92  million,  respectively,  of  unrecognized  tax  benefits  that  would 
impact our effective tax rate if recognized.

periods ending through December 31, 2012. All returns for periods ended 
through December 31, 2004, have been audited by and settled with the 
Internal Revenue Service (IRS).

We recognize accrued interest and penalties associated with uncertain 
tax positions as part of tax expense. For the years ended December 31, 
2017 and 2016 the amount recognized in interest expense is not material. 
The amounts accrued at December 31, 2017 and 2016 for the payment of 
interest and penalties were also not material.

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.

It is possible that the amount of unrecognized tax benefits will change 
due  to  one  or  more  of  the  following  events  during  the  next  twelve 
months: audit activity, tax payments, or final decisions in matters that 
are the subject of controversy in various jurisdictions within which we 
operate. The  majority  of  the  potential  change  relates  to  tax  litigation 
in  Korea  as  well  as  our  ongoing  U.S.  tax  audit.  We  believe  we  have 
provided  adequate  contingent  reserves  for  these  matters.  However,  if 
upon conclusion of these matters, the ultimate determination of taxes 
owed is for an amount materially different than our current reserves, our 
overall tax expense and effective tax rate could be materially impacted 
in the period of adjustment.

Corning Incorporated, as the common parent company, and all 80%-or-
more-owned of its U.S. subsidiaries join in the filing of consolidated U.S. 
federal  income  tax  returns.  The  statute  of  limitations  is  closed  for  all 

Our  foreign  subsidiaries  file  income  tax  returns  in  the  countries  in 
which  they  have  operations.  Generally,  these  countries  have  statutes 
of limitations ranging from 3 to 7 years. Years still open to examination 
by  foreign  tax  authorities  in  major  jurisdictions  include  Japan  (2009, 
2015  onward),  Taiwan  (2015  onward)  and  South  Korea  (2015  onward). 
Corning  is  currently  appealing  certain  tax  assessments  resulting  from 
audits performed by the South Korean tax authorities covering periods 
2006  through  2015. The  Company  is  required  to  deposit  the  disputed 
tax  amounts  with  the  South  Korean  government  as  a  condition  of  its 
appeal of  these assessments. Because we believe  that it is more likely 
than not that we will prevail in the appeals process, we have recorded a 
non-current receivable of $319 million for the amount on deposit with 
the South Korean government.

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

HSG and Dow Corning

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

Prior  to  realignment,  HSG,  a  consolidated  subsidiary  of  Dow  Corning, 
was an indirect equity investment of Corning. Upon completion of the 
exchange, Corning now has a direct equity investment in HSG. Because 
our  ownership  percentage  in  HSG  did  not  change  as  a  result  of  the 

realignment,  the  investment  in  HSG  is  recorded  at  its  carrying  value, 
which had a negative carrying value of $383 million at the transaction 
date.  The  negative  carrying  value  resulted  from  a  one-time  charge  to 
this  entity  in  2014  for  the  permanent  abandonment  of  certain  assets. 
Excluding this charge, the entity is profitable and is expected to recover 
its equity in the near term.

Corning’s  financial  statements  as  of  December  31,  2016  include  the 
positive impact of the release of a deferred tax liability of $105 million 
related  to  Corning’s  tax  on  Dow  Corning’s  earnings  that  were  not 
distributed  as  of  the  date  of  the  transaction  and  a  non-taxable  gain 
of $2,676 million on the realignment. Details of the gain are illustrated

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

Corning is currently appealing certain tax assessments resulting from audits performed by the South Korean tax authorities. The Company is required 
to deposit the disputed tax amounts with the South Korean government as a condition of its appeal of these assessments. Because we believe that it 
is more likely than not that we will prevail in the appeal process, we have recorded a non-current receivable for the amount on deposit with the South 
Korean government.

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

Asbestos Litigation
Corning  and  PPG  each  owned  50%  of  the  capital  stock  of  PCC.  Over  a  period  of  more  than  two  decades,  PCC  and  several  other  defendants  were 
named in numerous lawsuits involving claims alleging personal injury from exposure to asbestos. Refer to Note 14 (Commitments, Contingencies and 
Guarantees) to the Consolidated Financial Statements for additional information on the asbestos litigation.

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

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

facility  in  Hefei.  This  agreement  stipulates  that  the  customer  will 
provide a non-refundable cash deposit in the amount of approximately 
$400 million to Corning to secure rights to an amount of glass that is 
produced by Corning over  the next 10 years. Corning has collected  the 
full amount of this deposit, adjusted for foreign exchange movements, 
receiving  $185  million  of  this  deposit  in  2017  and  $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 2017 and 2016, there were no credit 
memoranda issued.

Debt Issuances and Retirements

2017

In  the  third  quarter  of  2017,  Corning  issued  three  Japanese  yen-
denominated debt securities (the “Notes”), as follows:

• ¥21 billion 0.698% senior unsecured long term notes with a maturity 

of 7 years;

• ¥47 billion 0.992% senior unsecured long term notes with a maturity 

of 10 years; and

• ¥10 billion 1.583% senior unsecured long term notes with a maturity of 

20 years.

The  proceeds  from  these  Notes  were  received  in  Japanese  yen  and 
converted  to  U.S.  dollars  on  the  date  of  issuance.  The  net  proceeds 
received 
in  U.S.  dollars,  after  deducting  offering  expenses,  was 
approximately  $700  million.  Payments  of  principal  and  interest  on 
the Notes will be in Japanese yen, or should yen be unavailable due to 
circumstances beyond Corning’s control, a U.S. dollar equivalent.

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 2017, we 
made no voluntary cash contributions to our domestic defined benefit 
pension plan and $29 million to our international pension plans. In 2016, 
we  made  voluntary  cash  contributions  of  $73  million  to  our  domestic 
defined benefit pension plan and $16 million to our international pension 
plans. We are not subject to any mandatory contributions in 2018, and 
anticipate  making  voluntary  cash  contributions  of  up  to  $105  million 
to  our  U.S.  qualified  pension  plan.  We  anticipate  contributing  up  to 
$27  million  to  our  international  pension  plans  in  2018.  The  amount 
recognized  in  accumulated  other  comprehensive  loss  and  not  yet 
reflected in periodic benefit cost expected to be amortized in next year’s 
periodic benefit cost is a net actuarial loss of $5.9 million.

On a quarterly basis, Corning will recognize  the  transaction gains and 
losses resulting from changes in the JPY/USD exchange rate in the Other 
expense, net line of the Consolidated Statements of (Loss) Income. Cash 
proceeds from  the offerings and payments for debt issuance costs are 
disclosed  as  financing  activities,  and  cash  payments  to  bondholders 
for interest will be disclosed as operating activities, in the Consolidated 
Statements of Cash Flows.

In the fourth quarter of 2017, Corning issued $750 million of 4.375% senior 
unsecured notes that mature on November 15, 2057. The net proceeds of 
$743 million will be used for general corporate purposes. We can redeem 
these notes at any time, subject to certain terms and conditions.

2016

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

Corning  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 attained for pre-65 retirees in 
2010. 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 2018 for its defined benefit 
pension plans. The Company expects to recognize no net actuarial gain 
and $3 million of net prior service credit as components of net periodic 
postretirement benefit cost in 2018.

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.

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. 

Corning last revised its mortality assumption for its U.S. benefits plans 
at year-end 2014 subsequent to the Society of Actuaries publication of 
the RP-2014 base mortality tables and MP-2014 mortality improvement 
scales.  At  that  time,  a  review  of  Corning’s  actual  mortality  experience 
for  its  retiree  population  was  undertaken  and  consideration  given  to 
Corning’s  view  of  future  mortality  improvements.  As  a  result  of  that 
study, Corning adopted the RP-2014 base mortality tables (white collar 
table  for  its  non-union  population  and  blue  collar  table  for  its  union 
population)  with  adjustments  to  those  tables  that  would  calibrate 
for  Corning’s  experience  to  the  extent  credible.  Based  on  Corning’s 
view  of  future  mortality  experience,  it  adopted  the  BB-2D  mortality 
improvement  scale  as  it  felt  that  scale  represented  the  best  available 
data to predict future improvement experience. 

70

CORNING INCORPORATED - 2017 Annual ReportIn  2017,  Corning  refreshed  its  analysis  of  its  own  retiree  mortality 
experience.  As  a  result  of  that  review,  Corning  decided  to  update  the 
adjustment  factors  applied  to  its  base  mortality  assumption  (RP-2014 
white  collar  table  and  RP-2014  blue  collar  table  for  non-union  and 
union participants respectively) to value its U.S. benefit plan obligations 
as  of  December  31,  2017.  In  addition,  as  the  Society  of  Actuaries  has 
published additional mortality improvement scales (MP-2015, MP-2016 
and  MP-2017),  Corning  has  considered  these  revised  improvement 
scales  in  setting  its  future  mortality  improvement  assumption.  As  of 
December  31,  2017,  Corning  decided  to  update  its  future  improvement 
scale to the MP-2017 scale.

Furthermore,  Corning  has  updated  the  mortality  assumption  applied 
to disabled participants to be the RP-2014 disabled mortality base table 
with future improvements using MP-2017. 

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

Moving  to  a  more  granular  approach  has  a  limited  impact  on 
the  determination  of  the  respective  benefit  obligations.  The  only 
impacts  will  be  as  a  result  of  the  elimination  of  the  rounding  of 

Notes to Consolidated Financial Statements

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

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

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

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

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.

Currency Risk

14%  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.

8%  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, 2017 and 2016, the amount of Corning common stock 
included in equity securities was not significant.

Cash Flow Data

In 2018, we expect to make voluntary cash contributions of approximately 
$106 million to our domestic defined benefit plan and expect to make 
voluntary contributions of approximately $27 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, 2017, $39 million of the $75 million was included in other accrued liabilities on our consolidated balance sheets.

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

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

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

(5)  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.

(6) At December 31, 2017, $54 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.

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.

Total rental expense was $135 million for 2017, $105 million for 2016 and

Product  warranty  liability  accruals  at  December  31,  2017  and  2016 
are insignificant.

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, 
2017, 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.

Corning  is  a  defendant  in  various  lawsuits  and  is  subject  to  various 
claims that arise in the normal course of business, the most significant 
of  which  are  summarized  below.  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.

CORNING INCORPORATED - 2017 Annual ReportPittsburgh Corning Corporation
Corning  and  PPG  Industries,  Inc.  each  owned  50%  of  the  capital  stock 
of  Pittsburgh  Corning  Corporation  (“PCC”).  PCC  filed  for  Chapter  11 
reorganization  in  2000  and  the  Modified  Third  Amended  Plan  of 
Reorganization  for  PCC  (the “Plan”)  became  effective  in  April  2016.  At 
December 31, 2015, the Company’s liability under the Plan was estimated 
to  be  $528  million.  At  December  31,  2016,  this  estimated  liability  was 
$290 million, due to the Company’s contribution, in the second quarter 
of 2016, of its equity interests in PCC and Pittsburgh Corning Europe N.V. 
in  the  total  amount  of  $238  million,  as  required  by  the  Plan.  Corning 
recognized  a  gain  of  $56  million  in  the  second  quarter  of  2016  in  the 
selling,  general  and  administrative  expenses  line  of  the  Company’s 
Consolidated  Statements  of  (Loss)  Income  for  the  difference  between 
the  fair  value  of  the  asbestos  litigation  liability  and  carrying  value  of 
the  investment.  This  gain  includes  the  release  of  foreign  translation 
losses in the amount of $25 million reclassified from accumulated other 
comprehensive  income. The  remaining  $290  million  liability  is  for  the 
series of fixed payments required by the Plan. At December 31, 2017, the 
liability was reduced to $220 million due to a cash payment of $70 million 
in the second quarter of 2017, as required by the Plan. The total amount 
of the payments due in years 2019 through 2022 is $185 million and is 
classified as a non-current liability at December 31, 2017. The remaining 
$35 million payment is due in the second quarter of 2018 and is classified 
as a current liability.

Notes to Consolidated Financial Statements

Asbestos Litigation
Corning is a defendant in certain cases alleging personal injuries from 
exposure to asbestos. Corning has been defending the claims in these 
cases, which are covered in part by insurance, without material impact 
to Corning to date. Corning previously established a $150 million reserve 
for these non-PCC asbestos claims. The estimated reserve represents the 
undiscounted  projection  of  claims  and  related  legal  fees. The  amount 
may  need  to  be  adjusted  in  future  periods  as  more  data  becomes 
available;  however,  we  cannot  estimate  any  lesser  or  greater  liabilities 
at this time.

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 related to asbestos claims. Corning has resolved these 
issues with all of its solvent insurers and some of its insolvent insurers. 
Corning  continues  to  seek  resolution  with  the  remaining  insolvent 
insurers. Management is unable to predict the outcome of the litigation 
with these remaining insolvent insurers.

Dow Corning Chapter 11 Related Matters
Until June 1, 2016, Corning and The Dow Chemical Company (“Dow”) each 
owned  50%  of  the  common  stock  of  Dow  Corning  Corporation  (“Dow 
Corning”). On May 31, 2016, Corning and Dow realigned their ownership 
interest  in  Dow  Corning.  In  connection  with  the  realignment,  Corning 
retained its indirect ownership interest in the Hemlock Semiconductor 
Group and acquired HS Upstate, Inc. (now known as Corning Research & 
Development Corporation) which had been capitalized by Dow Corning 
with $4.8 billion. Following the realignment, Corning no longer owns any 
interest  in  Dow  Corning.  In  connection  with  the  realignment,  Corning 
agreed to indemnify Dow Corning for 50% of Dow Corning’s non-ordinary 
course,  pre-closing  liabilities  to  the  extent  such  liabilities  exceed  the 
amounts reserved for them by Dow Corning as of May 31, 2016, including 
two  legacy  Dow  Corning  matters:  the  Dow  Corning  Breast  Implant 
Litigation, and the Dow Corning Bankruptcy Pendency Interest Claims.

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 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 May 31, 2016, Dow Corning had recorded a reserve for breast 
implant  litigation  of  $290  million.  In  the  event  Dow  Corning’s  total 
liability for these claims exceeds such amount, Corning may be required 
to indemnify Dow Corning for up 50% of the excess liability.

Dow Corning Bankruptcy Pendency Interest Claims

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, 
2017,  Dow  Corning  has  estimated  the  liability  to  commercial  creditors 
to be within the range of $77 million to $260 million. As of May 31, 2016, 
Dow Corning had recorded a reserve for these claims of $107 million. In 
the event Dow Corning’s liability for these claims exceeds such amount, 
Corning may be required to indemnify Dow Corning for up 50% of the 
excess liability, subject to certain conditions and limits.

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

Environmental Litigation
Corning has been named by the Environmental Protection Agency (the 
Agency) under the Superfund Act, or by state governments under similar 
state laws, as a potentially responsible party for 15 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,  2017  and 
December  31,  2016,  Corning  had  accrued  approximately  $38  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.

15.  Hedging Activities

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

The areas in which exchange rate fluctuations affect us include:

• Financial  instruments  and  transactions  denominated  in  foreign 

currencies, which impact earnings; and

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

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

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

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

76

Corning  uses  a  regression  analysis  to  monitor  the  effectiveness  of 
its  cash  flow  hedges  both  prospectively  and  retrospectively.  Through 
December  31,  2017,  the  hedge 
ineffectiveness  related  to  these 
instruments  was  not  material.  Corning  defers  net  gains  and  losses 
related to effective portion of cash flow hedges into accumulated other 
comprehensive loss on the consolidated balance sheet until such time 
as the hedged item impacts earnings. At December 31, 2017, the amount 
expected to be reclassified into earnings within the next 12 months is a 
pre-tax net gain of $20 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, 2017.

Net  gains  and  losses  from  fair  value  hedges  and  the  effects  of  the 
corresponding hedged item are recorded on  the same line item in  the 
Consolidated Statements of (Loss) Income.

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

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

CORNING INCORPORATED - 2017 Annual ReportNotes to Consolidated Financial Statements

The Company continued to extend its foreign exchange hedge program 
in  2017  and  entered  into  a  series  of  average  rate  forwards.  These  will 
hedge a significant portion of its projected yen exposure for the period 
of 2018-2022. As of December 31, 2017, the U.S. dollar net notional value 
of  the  yen  average  rate  forwards  program  is  $12  billion.  The  average 
rate forward program was also expanded to partially hedge the impact 
of  the  South  Korean  won,  New  Taiwan  dollar,  Chinese  yuan  and  euro 
translation on the Company’s projected net income. As of December 31, 
2017 these average rate forwards have a total notional value of $1 billion. 

The  entire  average  rate  forward  program  will  settle  net  without 
obligation  to  deliver  Japanese  yen,  Korean  won,  New  Taiwan  dollar, 
Chinese yuan and euro.

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

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.

CORNING INCORPORATED - 2017 Annual Report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  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  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 

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, 2017, 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.

Notes to Consolidated Financial Statements

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

As of December 31, 2017, the fair value of the contingent consideration in 
2018 was $300 million.

There were no significant financial assets and liabilities measured on a 
nonrecurring basis during the years ended December 31, 2017 and 2016.

Share Repurchases 

2015 Share Repurchases

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

On  October  28,  2015,  Corning  entered  into  an  ASR  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 
on  October  29,  2015  and  received  an  initial  delivery  of  approximately 
53.1  million  shares  of  Corning  common  stock  on  the  same  day.  On 
January  19,  2016,  the  2015  ASR  agreement  was  completed.  Corning 
received an additional 15.9 million shares on January 22, 2016  to settle 
the 2015 ASR agreement. In total, Corning purchased 69 million shares 
based on the average daily volume weighted-average price of Corning’s 
common  stock  during  the  term  of  the  2015  ASR  agreement,  less 
a discount. 

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

In  July  2016,  Corning  entered  into  an  accelerated  share  repurchase

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

In  December  2016,  Corning’s  Board  of  Directors  approved  a  $4  billion 
share  repurchase  program  with  no  expiration  (the  “2016  Repurchase 
Program”).  In  the  second  quarter  of  2017,  Corning  entered  into  and 
finalized  an  accelerated  share  repurchase  agreement  under  which  we 
paid $500 million for a total of 17.1 million shares. In the third quarter of 
2017, Corning entered into and finalized an additional accelerated share 
repurchase agreement under which we paid $500 million for a total of 
17.2  million  shares.  Collectively,  these  two  agreements  represent  the 
“2017 ASR agreements”.

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

In  addition  to  the  2017  ASR  agreements,  during  the  year  ended 
December  31,  2017,  the  Company  repurchased  50.1  million  shares  of 
common  stock  on  the  open  market  for  approximately  $1.4  billion, 
resulting in a total of 84.4 million shares repurchased for approximately 
$2.4 billion during 2017.

18.  (Loss) Earnings Per Common Share

Basic (loss) 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 (loss) 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 (loss) earnings per common share from operations follows (in millions, except 
per share amounts):

Net (loss) income attributable to Corning Incorporated

Less: Series A convertible preferred stock dividend

Net (loss) income available to common stockholders - basic

Plus: Series A convertible preferred stock dividend

Net (loss) 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(1)

Weighted-average common shares outstanding - diluted

Basic (loss) earnings per common share

Diluted (loss) earnings per common share

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

Series A convertible preferred stock dividend(1)

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,  2017,  there 
were  approximately  65  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  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,  $42  million  and 
$46  million  was  disclosed  in  operating  activities  on  the  Company’s 
Consolidated Statements of Cash Flows for the years ended December 31, 
2017, 2016 and 2015, respectively. The income  tax benefit realized from 
share-based  compensation  was  not  significant  for  the  years  ended 
December 31, 2017, 2016 and 2015. Refer to Note 6 (Income Taxes).

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, 2017:

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  29,  2017, 
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,  2017, 
was approximately 13 million.

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

The weighted-average grant-date fair value for options granted for the 
years ended December 31, 2017, 2016 and 2015 was $8.40, $6.31 and $7.99, 
respectively. The total fair value of options that vested during the years 
ended December 31, 2017, 2016 and 2015 was approximately $13 million, 
$22 million and $36 million, respectively. Compensation cost related to 
stock options for the years ended December 31, 2017, 2016 and 2015, was 
approximately $12 million, $11 million and $14 million, respectively.

As  of  December  31,  2017,  there  was  approximately  $6  million  of 
unrecognized compensation cost related to stock options granted under 
the Plans. The cost is expected to be recognized over a weighted-average 
period of 1.8 years.

Proceeds received from the exercise of stock options were $309 million 
for the year ended December 31, 2017, 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, 
2017,  2016  and  2015  was  approximately  $103  million,  $53  million  and 
$48 million, respectively.

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

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

Time-Based Restricted Stock and Restricted Stock Units:

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

The following table represents a summary of the status of the Company’s 
non-vested time-based restricted stock and restricted stock units as of 
December 31, 2016, and changes which occurred during the year ended 
December 31, 2017:

As  of  December  31,  2017,  there  was  approximately  $41  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  2.6  years.  The  total  fair  value  of  time-
based restricted stock that vested during the years ended December 31, 
2017,  2016  and  2015  was  approximately  $30  million,  $27  million  and 
$32  million,  respectively.  Compensation  cost  related  to  time-based 
restricted stock and restricted stock units was approximately $34 million, 
$31 million and $32 million for the years ended December 31, 2017, 2016 
and 2015, respectively.

All  other  segments  that  do  not  meet  the  quantitative  threshold  for 
separate  reporting  have  been  grouped  as  “All  Other.”  This  group  is 
primarily comprised of  the results of  the pharmaceutical  technologies 
business  and  new  product  lines  and  development  projects,  as  well 
as  certain  corporate  investments  such  as  Eurokera  and  Keraglass 
equity affiliates.

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