To Our 
Shareholders:

2018 was a terrific year for Corning. We grew core sales 
and earnings per share. We returned cash to shareholders 
through stock buybacks and a double-digit dividend increase. 
We won new customers. And we launched new products that 
continue our track record of innovation. Most importantly, 
we have positioned the company for sustainable, long-term 
growth by delivering on our Strategy and Capital Allocation 
Framework.

Since introducing the Framework in October 2015, we have 
been investing for growth through a combination of capacity 
expansions, strategic acquisitions, and innovation programs. 
In 2018, the benefits of our investments became apparent 
as we improved our financial performance and extended 
our leadership in all businesses. Our execution has been 
strong, and we expect our momentum to continue in 2019 
and beyond.

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

Financial Performance

Before I review our execution against the Framework 
in more detail, here are some highlights from Corning’s 2018 
financial results. 

Core sales were $11.4 billion and core earnings per 
share were $1.78, both up 11 percent year over year. From my 
perspective as CEO, two observations are particularly worth 
noting. First, our performance improved significantly in the 
second half of the year as we introduced new innovations, 
extended our cost leadership, and increased our capacity.  
We went from a $10 billion run rate at the beginning of  
the year to a $12 billion run rate with expanded margins  
in the second half. This step change in performance 
illustrates the benefits of our investments and strategy. 
Second, all of Corning's major businesses produced year-
over-year sales increases in 2018. That means we are not 
only building a bigger company, we are also building a 
stronger, more resilient one.

Strategy and Capital Allocation Framework

Framework Execution and Results 

If you follow Corning closely, you are probably familiar 
with our Strategy and Capital Allocation Framework. But 
we believe it is worth reviewing, because we want to ensure 
you understand Corning’s priorities and our plan for achieving 
our goals.

The Framework articulates our strategy for leveraging 
Corning’s financial strength and focusing our portfolio to 
deliver value for our stakeholders. Under the Framework, 
we target generating $26 to $30 billion in cash between 
2016 and 2019. We plan to return more than $12.5 billion to 
our shareholders through repurchases and dividends, and 
invest $10 billion to extend our leadership and deliver growth. 
To advance our innovation effectiveness, 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 categories. We believe this 
approach increases our likelihood of success, reduces the cost 
of innovation, and creates stronger competitive advantages. 

So how are we doing? Our stakeholders are the ultimate 

judges of our performance, but we are extremely pleased 
with our execution. 

Since introducing the Framework more than three years 
ago, our cash generation is on target. Through the end of 2018, 
we have distributed $11.8 billion to shareholders through 
share repurchases and quarterly dividends. Repurchases have 
reduced outstanding shares by approximately 36 percent. We 
increased the annual dividend by 11.1 percent in February 2019, 
16.1 percent in February 2018, 14.8 percent in 2017, and 12.5 
percent in 2016, for a combined increase of 67 percent.
Investments in RD&E, capital expenditures, and 

acquisitions also remain on track, totaling $8.2 billion through 
the end of 2018. As previously noted, these investments are 
already having a positive impact on our financial results. For 
example, our new Gen 10.5 LCD plant was one of the factors 
in Display Technologies’ year-over-year sales improvement, 
while gasoline particulate filters (GPFs) contributed more 
than $50 million last year to Environmental Technologies' 
sales. Our strategic acquisitions and capital expansion 
projects helped drive Optical Communications sales up  
by nearly $400 million from the first half of the year to  
the second half.

We are also making good progress extending our leadership 
across our market-access platforms.

n 
In Optical Communications, we passed 45 million 
homes globally with Corning’s fiber-to-the-home solutions. 
We launched new products that reduce network costs 
and increase the speed of installation, such as an extreme- 
density cable for next-generation hyperscale data centers and 
a fiber that offers significant advantages for high-throughput 
transmission.  

n 

In Display, we achieved a substantial increase in 

profitability in the second half of 2018 as price declines 

moderated year-over-year to mid-single-digit percentages. 

We also extended our global leadership by successfully 

ramping the world’s first Gen 10.5 LCD glass plant.

n 

In Mobile Consumer Electronics, we made significant 

progress toward our goal of doubling sales over the next 

several years by capturing more value per device and winning 

in new device categories. We extended our leadership in the 

cover-glass market with the launch of Corning® Gorilla® Glass 

6. We benefited from stronger demand for glass on the back 

of smartphones, which enables wireless charging and higher 

data rates. And we launched Corning® Gorilla® Glass DX and 

DX plus, which provide enhanced anti-reflective optics and 

scratch resistance for wearable technology. 

n 

In Automotive, we exceeded $50 million in GPF sales 

in 2018, as new emissions regulations took effect in Europe. 

We began ramping dedicated capacity in China to support 

upcoming Chinese regulations and committed demand from 

customers, such as Changan Automobile. We also experienced 

strong customer pull for Gorilla Glass for Automotive. To date, 

we have been awarded more than 55 platforms globally, as 

customers value our ability to deliver 3D shapes, superior 

readability, and enhanced durability at a competitive cost. 

n 

In Life Sciences Vessels, we continued to grow faster 

than the market, driven by our innovative products for 

bioprocess and cell therapy. We made strong progress with 

Corning Valor® Glass, our revolutionary pharmaceutical

Corning Valor® Glass, our revolutionary pharmaceutical 

packaging solution, which helps protect patients and improve 
manufacturing throughput. Valor shipments increased 
fourfold from 2017 as we continue to support customers 
preparing for regulatory filings. We have also been scaling 
up production capabilities and announced our plans to 
construct a high-volume manufacturing facility for Valor 
in North Carolina.  

Looking Ahead

As proud as we are of our progress in 2018, we’re even 
more excited about what’s ahead. We are on track to fully 
deliver the goals of our Strategy and Capital Allocation 
Framework, and we expect 2019 to be another growth 
year. Longer term, important trends such as 5G, smart cars, 
connected homes, and augmented reality are converging 
around Corning’s capabilities. Bringing these trends to life 
requires technologies that have been our fundamental 
strengths for decades. Moreover, they are making us a vital 
participant in complex, interconnected ecosystems that 
continue to unlock new opportunities.

Here’s more detail on what we expect in each of our 
market-access platforms:

In Optical Communications, we are enabling the network 

n 
densification and integrated passive optical solutions 
necessary for 5G, while continuing to innovate for rapidly 
evolving applications, such as fiber to the home, hyperscale 
data centers, and in-building networks. We expect to continue 
growing at more than twice the rate of the communications 
infrastructure market, and we are confident in our ability 
to exceed our goal of $5 billion in annual sales by 2020, with 
further growth in the years ahead.

In Display, we look forward to a full year of stable returns. 
This will come not only from continued improvements in the 
pricing environment, but also volume growth driven by larger 
TV screen sizes and increasing shipments of Gen 10.5 LCD 
glass. Simultaneously, we continue to build on our industry 
leadership to support the next round of display innovations 
– e.g., higher resolution, expanding color gamut, and next-
generation displays.

n 
In Mobile Consumer Electronics, we continue to innovate 
for customers and secure more Corning content in leading 
mobile devices. We are also winning in new device categories, 
such as augmented reality. For example, we signed a long-
term agreement with WaveOptics in December to supply 
high-performance augmented reality optics. 

n 
In Automotive, our materials expertise is helping to 
propel the auto industry into a new era of cleaner vehicles 
with enhanced cockpit functionality, connectivity, and design. 
We expect sales of GPFs to continue ramping in 2019 and 
beyond, driven by regulations in Europe, with additional 
growth from the China market when new regulations take 
effect. We are also investing in Gorilla Glass for Automotive, 
and expect to bring new manufacturing capacity online  
in the second half of 2019. 

n  Finally, in Life Sciences Vessels, we expect to increase our 
cell-culture leadership position, driven by the industry’s move 
to cell therapies. Longer term, we continue to believe that 
Corning Valor® Glass has the potential to power Corning’s 
growth for the next decade and beyond. Key customers are 
advancing toward the FDA certification required for the use 
of Valor with each drug, and our development partners Merck 
and Pfizer are at the forefront.

Closing Thoughts

  When we introduced our Strategy and Capital Allocation 
Framework in 2015, we knew it would take time and relentless 
execution to deliver our goals. We asked for your confidence, 
and I believe we have earned it. But we never take that 
confidence for granted. We are committed to continuing 
to earn it every day with our performance, our innovations, 
and our actions.

I truly believe that Corning’s future has never been 
brighter. We have multiple businesses driving our growth. 
We have unique capabilities that are becoming increasingly 
vital. We are helping enable trends that matter. We have 
relationships with industry-leading customers that continue 
to unlock new opportunities. We have a proven track record  
of delivering results. And we have more than 50,000 employees 
around the globe committed to doing their part to make the 
company stronger and the world better.
  We look forward to delivering the Framework’s goals 
this year, unleashing new capabilities in the years ahead, 
and sharing milestones along the way. Thank you for being 
on this journey with us. 

Sincerely,

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

Making a Difference with More Than Our Products

At Corning, we believe how we do things is as important as what we achieve. We are committed to making 
the world a better place, not only with our innovations, but also with our actions.  

Here are some of the ways we are helping to create a sustainable future for the company, the communities where 
we operate, and the planet we all share.

Corning is doing its part to help protect the environment 
through the ongoing improvement of processes, products,  
and services. Since 2006, we have increased our energy  
efficiency by 35 percent, and we continue to identify new ways 
to use less energy. Last year, we expanded the use of solar 
panels at our facilities, launched an Employee Community Solar 
Program, and made our first investment in the China Clean 
Energy Fund. We also earned accolades for our environmental 
initiatives. In 2018, Corning won the Horizon 2020 Materials 
for Clean Air Award from the European Commission for our 
innovative air-purification technology. Corning also received its 
fifth consecutive ENERGY STAR® Partner of the Year award and 
third consecutive Sustained Excellence designation from the 
U.S. Environmental Protection Agency.

Corning invests to strengthen the economy and enhance 
the quality of life in the communities where we live and 
work. Our investments include support for libraries, daycare 
centers, schools, arts and cultural organizations, economic 
development initiatives, and infrastructure improvements. 
In 2018, we participated in the United Way Day of Action to 
promote hands-on volunteer efforts in our communities. We 
promoted literacy through initiatives such as the Corning 
Valley Read-In Program. We helped underprivileged children 
in China’s Sichuan Province gain better access to scientific 
education through programs such as “Corning Glass Class.” 
And we financed a new elementary school in Pune, India.  

Corning is committed to ensuring an inclusive environment  
for its employees around the world. In 2018, we celebrated 
the 50th anniversary of Corning's formal diversity initiative.  
What began in 1968 as a U.S.-centered, compliance-focused 
effort has grown into a global celebration of diversity and 
inclusion. Corning has received a score of 100 on the Corporate 
Equality Index for 14 consecutive years. Corning also earned 
a score of 100 on the 2018 Disability Equality Index and 
was recognized as a “Best Place to Work” by the American 
Association of People with Disabilities. In addition, Corning 
was named a "Best of the Best Corporation for Inclusion"  
by the National Gay & Lesbian Chamber of Commerce for 
the third year in a row.

In 2018, Corning’s commitment to positive environmental, 
social, and governance-related business practices resulted 
in receiving an “AA” rating by MSCI ESG Research, Inc., placing 
Corning among the top quartile of companies in our industry. 
We are proud of Corning’s achievements, but we know our 
sustainability efforts are a work in progress. In 2018, we  
appointed our first sustainability director, and we look  
forward to evolving our practices to continue making  
Corning a better version of itself.

Business Description

Corporate Investments

Dow Corning Corporation and Hemlock Semiconductor Group (“HSG”). 
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 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 held 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  recovered  its  equity 
during 2018.

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 5 (Investments) to the Consolidated Financial Statements.

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  2018,  Corning  was  granted  about  520  patents  in  the  U.S.  and  over 
1,430 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 2018, Corning and its wholly-
owned  subsidiaries  owned  over  11,600  unexpired  patents  in  various 
countries  of  which  over  4,400  were  U.S.  patents.  Between  2019  and 
2021, approximately 11% of these patents will expire, while at the same 
time Corning intends to seek patents protecting its newer innovations. 
Worldwide,  Corning  has  about  10,300  patent  applications  in  process, 
with about 2,500 in process in the U.S. Corning believes that its patent 
portfolio will continue to provide a competitive advantage in protecting 
the Company’s innovation, although Corning’s competitors in each of its 
businesses are actively seeking patent protection as well.

While  each  of  our  reportable  segments  has  numerous  patents  in 
various countries, no one patent is considered material to any of these 
segments.  Important  U.S.-issued  patents  in  our  reportable  segments 
include the following:

• Display  Technologies:  patents  relating  to  glass  compositions  and 
methods  for  the  use  and  manufacture  of  glass  substrates  for 
display applications.

Business Description

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

• Optical Communications: patents relating to (i) optical fiber products 
including  low-loss  optical  fiber,  high  data  rate  optical  fiber,  and 
dispersion  compensating  fiber,  and  processes  and  equipment  for

fiber  preforms  and  methods  for  drawing,  cooling  and  winding 
optical  fiber;  (ii)  optical  fiber  ribbons  and  methods  for  making  such 
ribbon,  fiber  optic  cable  designs  and  methods  for  installing  optical 
fiber  cable;  (iii)  optical  fiber  connectors,  hardware,  termination  and 
storage and associated methods of manufacture; and (iv) distributed 
communication systems.

• Environmental  Technologies:  patents  relating  to  cellular  ceramic 
honeycomb  products,  together  with  ceramic  batch  and  binder 
system  compositions,  honeycomb  extrusion  and  firing  processes, 
and  honeycomb  extrusion  dies  and  equipment  for  the  high-volume, 
low-cost manufacture of such products.

• Specialty Materials: patents relating to protective cover glass, ophthalmic

Business Description

Protection of the Environment

Corning  has  an  extensive  program  to  ensure  that  its  facilities  are  in 
compliance with state, federal and foreign pollution-control regulations. 
This  program  has  resulted  in  capital  and  operating  expenditures  each 
year. To maintain compliance with such regulations, capital expenditures 
for  pollution  control  in  operations  were  approximately  $11.3  million  in 
2018 and are estimated to be $21.1 million in 2019.

Corning’s  2018  consolidated  operating  results  were  charged  with 
approximately $47 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.

Employees

At  December  31,  2018,  Corning  had  approximately  51,500  full-time  employees.  From  time  to  time,  Corning  also  retains  consultants,  independent 
contractors, temporary and part-time workers.

Risk Factors

We  operate  in  rapidly  changing  economic,  political,  and  technological 
environments that present numerous risks. Our operations and financial 
results are subject to 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  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  our  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 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.  Additionally,  we  rely  on  a  global  supply 
chain for key components and capabilities that are central to our ability 
to invent, make and sell products.

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 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  operating  results.  Our  success  depends,  in  part,  on  our 
ability to anticipate and manage these risks.

CORNING INCORPORATED - 2018 Annual Report

Risk Factors

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

• Complex, or competing tax regimes;

• Difficulty in collecting obligations owed to us;

• 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  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;

• 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 
display 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 on the profitability of our display glass business, which is subject 
to  continuous  pricing  pressure  due  to  industry  competition,  potential 
over-capacity, and development of new technologies. If we are not able 
to  achieve  proportionate  reductions  in  costs  and  increases  in  volume 
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  end-customers  accounted  for  a  high 
percentage of net sales in each of our reportable segments. Mergers and 
consolidations between customers could result in further concentration 
of  Corning’s  customer  base.  Further  concentration,  or  the  loss  or 
insolvency of a key customer, could result in a substantial loss of sales 
and reduction in anticipated in cash flows.

The following table details the number of combined customers of our segments that accounted for a large percentage of segment net sales:

Display Technologies

Optical Communications

Specialty Materials

Environmental Technologies

Life Sciences

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.  Due  to  the  specialized  nature  of  the  assets,  in  the  event 
such  a  location  experiences  disruption,  it  may  not  be  possible  to  find 
replacement  capacity  quickly  or  substitute  production  from  other 
facilities. Accordingly, 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.

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  in 
regions  where  we  operate  could  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 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.

8 CORNING INCORPORATED - 2018 Annual Report

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  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

intrusion, 

The  Company  is  dependent  on  information  technology  systems  and 
infrastructure, including cloud-based services, (“IT systems”) to conduct 
its  business.  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, 
interruption  or 
corruption  of  these  systems  or  data  breaches  could  cause  the  loss 
of  data  or  intellectual  property,  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 
outbreaks,  unauthorized  access,  systems  failures  and  disruptions.  We 
have measures and defenses in place against such events, but we may 
not  be  able  to  prevent,  immediately  detect,  or  remediate  all  instances 
of  such  events.  A  material  security  breach  or  disruption  of  our  IT 
systems  could  result  in  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, 
impair our ability to access vendors, suppliers and cloud-based services, 
or otherwise adversely affect our business.

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

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

Developing our products through our innovation model of research and 
development is expensive and often involves a long investment cycle. We 
make significant expenditures and investments in research, development 
and engineering that may not earn an economic return. If our investments 
do not provide a pipeline of products or technologies that our customers 
demand or lower our manufacturing costs, 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 experience 
fluctuations in the US Dollar value of these activities 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 
changes (increases or decreases) and we are unable to reverse, unwind, 
or  terminate  the  hedges  concurrent  with  changes  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  ability  to  respond  to  price  moves 
by  our  Display  Technologies  segment  competitors.  Foreign  currency 
movements  may  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.

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  may  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.

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, components 
and  raw  materials  from  our  suppliers.  We  may  experience  shortages 
that  could  adversely  affect  our  operations.  Certain  manufacturing 
equipment,  components  and  raw  materials  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 to prevent disruption to our business.

Risk Factors

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

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

At December 31, 2018, Corning had goodwill and other intangible assets 
of  approximately  $3.2  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  as  projected  by  management  do  not  occur,  especially  if 
an  economic  downturn  occurs  and  continues  for  a  lengthy  period  or 
becomes severe, or if the Company’s acquisitions and investments 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;

• Changes in tax laws, tax treaties and regulations or the interpretation 
of them, including the impact of the Tax Cuts and Jobs Act (the “2017 
Tax Act”) which was 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 
where  the  ultimate  tax  determination 
is  uncertain.  Significant 
judgment  is  required  in  determining  our  worldwide  provision  for 
income  taxes.  Although  we  believe  our  tax  estimates  are  reasonable, 
the  final  determination  of  tax  audits  and  any  related  litigation  could 
be  materially  different  from  our  historical  income  tax  provisions  and 
accruals. The results of an audit or litigation could have a material effect 
on  our  financial  statements  in  the  period  or  periods  for  which  that 
determination is made.

The  2017  Tax  Act  significantly  impacted  how  U.S.  global  corporations 
are  taxed.  Among  other  things,  the  2017  Tax  Act  required  companies 
to pay a one-time mandatory tax on unrepatriated earnings of certain 
foreign subsidiaries that were previously tax deferred (the “toll charge”) 
and created new taxes on certain foreign sourced earnings. Significant 
guidance has been issued with the intention of clarifying the new tax 
provisions.  To  date,  a  considerable  amount  of  this  guidance  has  been 
issued in the form of proposed regulations. The volume and complexity 
of  the  proposed  regulations  as  well  as  the  impact  of  final  regulations 
which  were  recently  issued,  has  resulted  in  many  questions  regarding 
how the effect of such regulations should be considered. We continue to 
evaluate the impact of this legislation and certain changes could have a 
material adverse impact on our tax expense and cash flow.

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.

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 way existing laws might 
be administered or interpreted.

10 CORNING INCORPORATED - 2018 Annual Report

Legal Proceedings

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

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 in Note 12 (Commitments and Contingencies) to 
the Consolidated Financial Statements. 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.

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, 2018 and December 31, 2017, Corning had 
accrued  approximately  $30  million  (undiscounted)  and  $38  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.

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

Organization of Information
Management’s Discussion and Analysis provides a historical and prospective narrative on the Company’s financial condition and results of operations. 
This discussion includes the following sections:

• Overview

• Results of Operations

• Core Performance Measures

• Reportable Segments

• Liquidity and Capital Resources

Overview

• Environment

• Critical Accounting Estimates

• 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  $11.8  billion  to 
shareholders  through  share  repurchases  and  dividends,  and  increased 
the  annual  dividend  by  11.1%  in  2019,  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.

Highlights of progress in Corning’s market-access platforms include:

• Securing contracts with industry leaders in the carrier and data center 
segments  that  will  add  significant  sales  in  2019  and  beyond,  and 
completing the acquisition of CMD in Optical Communications;

• Extending  the  company’s  leadership  in  mobile  consumer  electronics 
with the launch and adoption of Gorilla Glass 6 as well as other cover 
glass and sensing technology innovations;

• Gaining  significant  new  sales  and  platforms  for  gasoline  particulate 
filters  and  strong  pull  for  Gorilla  Glass  for  Automotive  solutions, 
particularly  the 
industry’s  first  AutoGrade  Glass  Solutions  for 
automotive interiors, reaching more than 55 platforms to date;

14 CORNING INCORPORATED - 2018 Annual Report

• Increasing our shipments of Valor Glass by four  times year-over-year, 
indicating  progress  toward  certification  across  more  pharmaceutical 
companies in Life Sciences Vessels; and

• Reaching  stable  returns  in  Display Technologies  as  the  glass  pricing 
environment  continued  to  improve  and  Corning  extended  global 
leadership  by  successfully  ramping  the  world’s  first  Gen  10.5  LCD 
glass plant.

2018 Results
Net  sales  in  the  year  ended  December  31,  2018  were  $11.3  billion,  an 
increase  of  $1.2  billion,  or  12%,  when  compared  to  the  year  ended 
December 31, 2017, driven by sales increases across all segments.

For the year ended December 31, 2018, we generated net income of $1.1 
billion, or $1.13 per share, compared to a net loss of $0.5 billion, or $(0.66) 
per  share,  for  2017.  When  compared  to  2017,  the  $1.6  billion  increase 
in  net  income  was  primarily  due  to  the  following  items  (amounts 
presented after tax):

• The  absence  of  $1.5  billion  in  tax  reform  adjustments  related  to  the 

2017 Tax Act;

• Higher  segment  net 

in  our  Optical  Communications, 
Environmental  Technologies,  Specialty  Materials  and  Life  Sciences 
segments,  up  $123  million,  $43  million,  $12  million  and  $22  million, 
respectively; and

income 

• The positive impact of $48 million in tax adjustments, primarily related 
to changes in the valuation allowances on deferred tax assets offset by 
the preliminary 2013-2014 IRS audit settlement.

Partially offsetting these events were the following items:

• An  increase  of  $105  million  in  legal  expenses,  driven  by  a  ruling 
in  civil 

lawsuit  and  developments 

intellectual  property 

in  an 
litigation matters;

• An impact of $99 million resulting from an increase of mark-to-market 

loss for our defined benefit pension plans; and

• Lower segment net income in our Display Technologies and All Other 
segments in the amount of $53 million and $22 million, respectively.

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

to  improve  further  to  a  mid-single  digit  percentage.  We  anticipate 
Corning’s  display  glass  volume  will  grow  faster  than  the  expected 
display  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 low-
teens in percentage  terms, including  the impact of a full year of sales 
from  the  acquisition  of  3M’s  Communication  Markets  Division.  We 
expect high-single digit sales growth in our Environmental Technologies 
segment.  We  expect  growth  in  the  Specialty  Materials  segment,  the 
rate  of  which  will  depend  on  the  adoption  of  our  innovations.  We 
anticipate low to mid-single digit percentage growth in sales for the Life 
Sciences segment.

Diluted earnings per share increased by $1.79 per share, or 271%, when 
compared to 2017, driven by the increase in net income described above, 
coupled  with  the  repurchase  of  74.8  million  shares  of  common  stock 
over the last twelve months.

The  translation  impact  of  fluctuations  in  foreign  currency  exchange 
rates,  including  the  impact  of  hedges  realized  in  2018,  did  not 
materially impact Corning’s consolidated net income in the year ended 
December 31, 2018 when compared to the year ended December 31, 2017.

2019 Corporate Outlook
We believe 2019 will be another year of strong growth and investment, 
consistent with our Strategy and Capital Allocation Framework. In our 
Display Technologies  segment,  we  expect  full  year  2019  price  declines

For  the  year  ended  December  31,  2018,  segment  net  sales  increased 
by  $1.1  billion,  or  11%,  when  compared  to  the  same  period  in  2017. The 
primary sales drivers by segment were as follows:

• Display  Technologies  segment  net  sales  increased  $139  million 
compared to the prior year. Total display glass market volume was up in 
2018. Our volume growth in this market more than offset price declines 
on  a  year-over-year  basis.  2018  was  the  best  pricing  environment  in 
more than a decade, achieving the important milestone of mid-single 
digit year-over-year declines during the second half of the year;

• An increase of $647 million in the Optical Communications segment, 
due to higher sales of carrier and enterprise network products, up $364 
million and $283 million, respectively. The acquisition of CMD driving 
$200 million of the increase in sales;

• An increase of $76 million in the Specialty Materials segment driven by 
higher net sales of Gorilla Glass products, advanced optics and other 
specialty glass;

• An  increase  of  $183  million  in  the  Environmental  Technologies 
segment, driven by sales growth in all categories including sales of gas 
particulate filters; and

• An increase of $67 million in the Life Sciences segment, as the business 

continued to outpace the market.

Movements  in  foreign  exchange  rates  did  not  materially  impact 
Corning’s  consolidated  net  sales  in  the  year  ended  December  31, 2018, 
respectively, when compared to the same period in 2017.

For the year ended December 31, 2017, net sales increased by $818 million, 
or  9%,  when  compared  to  the  same  period  in  2016. The  primary  sales 
drivers by segment were as follows:

• A decrease of $151 million in the Display Technologies segment, driven 
by price declines of approximately 10%, 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.  Strong 
growth  in  the  North  American  market  drove  the  increase  in  carrier 
network products;

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

• An increase of $74 million in the Environmental Technologies segment, 
driven by higher net 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  $40  million  in  the  Life  Sciences  segment,  driven  by 

higher sales in North America and China; and

• An  increase  of  $36  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.

In 2018, 2017 and 2016, sales in international markets accounted for 69%, 
69% and 72%, 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, 2018, gross margin dollars increased by 
$441 million, or 11%, and gross margin as a percentage of net sales was 
consistent when compared to the same period last year. The increase in 
gross margin dollars was primarily driven by the following items:

• Higher  sales  in  the  Optical  Communications  segment,  driven  by 
growth in Carrier and Enterprise products, resulting in increased gross 
margin of $291 million;

• An  increase  in  Gorilla  Glass  and  advanced  optics  product  volume 

which contributed $48 million to gross margin; and

• Higher sales in the Environmental technologies segment drove an $85 

million increase.

Gross margin increases were partially offset by higher costs related  to 
capacity  expansions  across  multiple  business  segments  and  display 
glass price declines.

16 CORNING INCORPORATED - 2018 Annual Report

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

Movements  in  foreign  exchange  rates  did  not  materially  impact 
Corning’s  consolidated  gross  margin  in  the  year  ended  December  31, 
2018, respectively, when compared to the same period in 2017.

When compared  to  the year ended December 31, 2016, selling, general 
and administrative expenses increased by $11 million in the year ended 
December 31, 2017. The increase was due to the following items:

In  the  year  ended  December  31,  2017,  gross  margin  dollars  increased 
by  $257  million,  or  7%,  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 Display Technologies segment, offset by higher 

costs related to capacity expansion;

• 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

• 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.

Display  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.

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.

Selling, General and Administrative Expenses
When  compared  to  the  year  ended  December  31,  2017,  selling,  general 
and  administrative  expenses  increased  by  $326  million,  or  22%,  in  the 
year  ended  December  31,  2018.  Selling,  general  and  administrative 
expenses  increased  by  1%  as  a  percentage  of  sales.  The  increase  was 
primarily driven by the following items:

• An increase of $137 million in litigation and other legal expenses, driven 
by  a  ruling  in  an  intellectual  property  lawsuit  and  developments  in 
commercial litigation matters;

• An increase in the Optical Communications segment, up $65 million, 

largely driven by the acquisition of CMD;

• Increased corporate expenses of $55 million;

• Increased acquisition related costs of $25 million; and

• Increased costs in our emerging businesses, up $20 million, driven by 

investments in new customers and new business growth.

• 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

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

support of new product launches.

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

Research, Development and Engineering 
Expenses
For  year  ended  December  31,  2018,  research,  development  and 
engineering expenses increased by $129 million, or 15%, when compared 
to  2017,  driven  by  higher  costs  associated  with  new  product  launches 
and our emerging businesses. As a percentage of sales, these expenses 
were flat when compared to the same period last year.

In  the  year  ended  December  31,  2017,  research,  development  and 
engineering expenses increased by $128 million, or 17%, 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  decreased  one  percent  when 
compared to the same period last year.

(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 HSG 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 held an equity interest in Hemlock 
Semiconductor Group (HSG) 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  (HSG)  businesses  of  Dow  Corning  from  January  1, 
2016  through  May  31, 2016.  Prior  to  the  realignment  of  Dow  Corning, 

equity  earnings  from  the  HSG  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, HSG was 
converted  to a partnership. Each of  the partners is responsible for  the 
taxes  on  their  portion  of  equity  earnings. Therefore,  post-realignment, 
HSG’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 12 (Commitments, Contingencies and Guarantees) to the 
consolidated financial statements for additional information.

In December 2017,  the U.S. enacted  the 2017 Tax Act which resulted in 
significant changes for our financial results, including, but not limited 
to, (1) reducing the U.S. federal corporate income tax rate to 21%, and (2) 
imposing a one-time toll charge tax on certain unrepatriated earnings 
of foreign subsidiaries of U.S. companies  that had not been previously 
taxed in the U.S.

Given  the  significant  complexity  of  the  2017  Tax  Act  and  the  lack  of 
clear  tax  and  accounting  regulatory  guidance  for  this  new  law,  the 
Securities Exchange Commission 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  was  required  to  record  those  items  where  ASC  740 
analysis was complete; include reasonable estimates and label them as 
provisional  where  ASC  740  analysis  was  incomplete;  and  if  reasonable 
estimates could not be made, record items under the previous tax law. 
The measurement period, not to exceed one year, ended on the date the 
entity had obtained, prepared, and analyzed  the information  that was 
needed to complete the accounting requirements under ASC Topic 740.

The 2017 Tax Act also established new tax provisions affecting our 2018 
results, including, but not limited to: (1) Creating a new provision to tax 
global intangible low-taxed income (GILTI); (2) generally eliminating U.S. 
federal  taxes  on  dividends  from  foreign  subsidiaries;  (3)  eliminating 
the  corporate  alternative  minimum  tax  (“AMT”);  (4)  creating  the  base 
erosion anti-abuse tax (“BEAT”); (5) establishing a deduction for foreign 
derived  intangible  income  (“FDII”);  (6)  establishing  new  limitations  on 
deductible interest expense; and (7) establishing new limitations on the 
deductibility of certain executive compensation.

(Provision) benefit for income taxes

Effective tax rate (benefit)

For  the  year  ended  December  31,  2018,  the  effective  income  tax  rate 
differed from the U.S. statutory rate of 21% primarily due to the following:

• Additional taxes of $55 million related primarily to the global intangible 

low-taxed income (“GILTI”) provisions of the 2017 Tax Act; and

• Incremental  tax  expense  of  $172  million  related  to  a  preliminary 
agreement with the IRS for the income tax audit of years 2013 and 2014.

These items were partially offset by the following:

• A benefit of $35 million related to the finalization of the one-time toll 

charge recorded in 2017; and

• An  $82  million  benefit  from  the  release  of  a  valuation  allowance  on 

deferred tax assets that are now considered realizable.

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:

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

• The result of a provisional tax expense of $347 million 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.

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

For  the  year  ended  December  31,  2018,  Corning’s  results  included  a 
worldwide  tax  provision  of  $437  million,  inclusive  of  tax  on  ongoing 
operations  of  $412  million  and  the  impacts  of  the  2017 Tax  Act  of  $25 
million. The impacts of the 2017 Tax Act include: GILTI tax of $55 million, 
FDII benefit of $10 million, and a $20 million benefit related to truing up 
the  toll  charge  and  our  measurement  of  U.S.  deferred  taxes,  offset  by 
the recording of a provision related to lifting our assertion of indefinite 
reinvestment  on  certain  foreign  earnings.  As  of  December  31,  2018, 
Corning has completed its analysis of the impact of the 2017 Tax Act as 
required by SAB 118. The GILTI tax of $55 million was largely driven by the 
receipt of customer deposits. See Note 2 (Revenue) to these Consolidated 
Financial Statements for more information.

Corning  has  completed  its  analysis  on  the  impact  of  the  2017 Tax  Act 
on  its  assertion  regarding  its  indefinitely  reinvested  foreign  earnings. 
Corning  has  determined  that  it  will  no  longer  assert  indefinite 
asset  reinvestment  on  $15.4  billion  of  unremitted  foreign  earnings 
accumulated  prior  to  2018.  This  represents  approximately  94%  of 
Corning’s unremitted foreign earnings as of the end of 2017. Corning will 
continue  to  indefinitely  reinvest  the  remaining  6%  of  historic  foreign 
earnings as of December 31, 2017.

Beginning in 2018, Corning will indefinitely reinvest the foreign earnings 
of: (1) any of its subsidiaries located in jurisdictions where Corning lacks 
the  ability  to  repatriate  its  earnings,  (2)  any  of  its  subsidiaries  where 
Corning’s intention is to reinvest those earnings in operations, (3) legal 
entities  for  which  Corning  holds  a  non-controlling  interest,  (4)  any 
subsidiaries  with  an  accumulated  deficit  in  earnings  and  profits  and 
(5) any subsidiaries which have a positive earnings and profits balance 
but for which the entity lacks sufficient local statutory earnings or stock 
basis from which to make a distribution.

During  2018,  the  Company  distributed  approximately  $4.2  billion  from 
foreign  subsidiaries  to  their  respective  U.S.  parent  companies.  There 
are  no  incremental  taxes  beyond  the  toll  charge  due  with  respect  to 
these distributions. As of December 31, 2018, Corning has approximately 
$1.5  billion  of  indefinitely  reinvested  foreign  earnings.  It  remains 
impracticable  to  calculate  the  tax  cost  of  repatriating  our  unremitted 
earnings which are considered indefinitely reinvested.

Refer to Note 4 (Income Taxes) to the Consolidated Financial Statements 
for further details regarding income tax matters.

2018 vs. 2017

For the year ended December 31, 2018, comprehensive income increased 
by $0.6 billion, when compared to the same period in 2017, driven by an 
increase in net income of $1.6 billion largely driven by the absence of $1.5 
billion in tax reform adjustments related to the 2017 Tax Act.

Partially offsetting  this increase was a decrease in  the gain on foreign 
currency  translation  adjustments  in  the  amount  of  $0.9  billion 
(after-tax),  largely  driven  by  the  strengthening  of  foreign  currencies, 
most  significantly  the  South  Korean  won,  euro  and  the  Chinese  yuan, 
which impacted comprehensive income in the amounts of $556 million, 
$156 million and $114 million, respectively.

20 CORNING INCORPORATED - 2018 Annual Report

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

2017 vs. 2016

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.

See  Note  11  (Employee  Retirement  Plans)  and  Note  15  (Shareholders’ 
Equity) to the Consolidated Financial Statements for additional details.

Core Performance Measures

In  managing  the  Company  and  assessing  our  financial  performance, 
we  adjust  certain  measures  provided  by  our  consolidated  financial 
statements  to  exclude  specific  items  to  arrive  at  core  performance 
measures.  These  items  include  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. Additionally, Corning has adopted the use of constant 
currency reporting for our Display Technologies and Specialty Materials 
segments  for  the  Japanese  yen,  South  Korean  won,  Chinese  yuan  and 
New  Taiwan  dollar  currencies.  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. Corning also believes that reporting core performance measures 
provides investors greater transparency to the information used by our 
management team to make financial and operational decisions.

Core  performance  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 
outlook  for  future  periods,  it  is  not  possible  to  provide  reconciliations 
for these non-GAAP measures because the Company does not forecast 
the  movement  of  the  Japanese  yen,  South  Korean  won,  Chinese  yuan 
or New Taiwan dollar 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.

For a reconciliation of non-GAAP performance measures  to  their most 
directly comparable GAAP financial measure, please see “Reconciliation 
of Non-GAAP Measures” below.

Core Earnings

2018 vs. 2017

2017 vs. 2016

In  the  year  ended  December  31,  2018,  we  generated  core  earnings  of 
$1,673 million or $1.78 per share, compared  to core earnings generated 
in  the  year  ended  December  31,  2017  of  $1,634  million,  or  $1.60  per 
share.  The  increase  in  core  earnings  of  $39  million  was  driven  by  the 
following items:

In  the  year  ended  December  31,  2017,  we  generated  core  earnings  of 
$1,634 million or $1.60 per share, compared to core earnings generated 
in  the  year  ended  December  31,  2016  of  $1,651  million,  or  $1.44  per 
share.  The  decrease  in  core  earnings  of  $17  million  was  driven  by  the 
following items:

• An increase in  the Optical Communications segment of $123 million, 

driven by higher sales of carrier and enterprise network products;

• An increase in the Environmental Technologies segment of $43 million 

resulting from sales growth across all product lines;

• An increase of $22 million in the Life Sciences segment resulting from 

higher sales, as well as improved manufacturing efficiencies; and

• An increase of $12 million in the Specialty Materials segment driven by 
higher sales of Gorilla Glass, advanced optics and other specialty glass.

Partially offsetting these increases in earnings were the following:

• A  decrease  in  the  Display Technologies  segment  of  $53  million,  with 
the  costs  of  expanding  Gen  10.5  capacity,  ramping  production  and 
rebuilding tanks for fleet optimization during the first half of the year 
more than offsetting increased sales;

• A  decrease  of  $22  million  in  the  All  Other  segment  resulting  from 

increased investment in development projects;

• Increased financing expenses of $30 million; and

• Increased corporate project expenses $39 million.

Core earnings per share increased in the year ended December 31, 2018 to 
$1.78 per share, driven by the increase in core income and lower weighted 
average  shares  outstanding  due  to  repurchases  of  our  common  stock 
during 2018.

• The  absence  of  equity  earnings  of  $98  million  from  Dow  Corning’s 
silicones  business  due  to  our  2016  realignment  of  our  ownership 
interest in Dow Corning;

• A decrease of $65 million in the Display Technologies segment, driven 
by display glass price declines of approximately 10%, partially offset by 
an increase in volume in the mid-single digits in percentage terms; and

• 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 $118 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 
$73 million, driven by an increase in Corning Gorilla Glass and advanced 
optics products.

Although core net earnings decreased in  the year ended December 31, 
2017,  core  earnings  per  share  increased  $0.16  per  share,  driven  by 
lower weighted average shares outstanding due to repurchases of our 
common stock in 2017.

Included  in  core  earnings  for  the  years  ended  December  31, 2018, 2017 
and 2016 is net periodic pension expense in the amount of $52 million, 
$49  million  and  $51  million,  respectively,  which  excludes  the  annual 
pension mark-to-market adjustments. In the years ended December 31, 
2018, 2017 and 2016, the mark-to-market adjustments pre-tax losses of 
$145 million, $21 million and $67 million, respectively.

Refer  to  Note  11  (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.

The  following  tables  reconcile  our  non-GAAP  financial  measures  to  their  most  directly  comparable  GAAP  financial  measure  (amounts  in  millions

24 CORNING INCORPORATED - 2018 Annual Report

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

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

(1)  Constant-currency adjustments: Because a significant portion of Display Technologies segment revenues are denominated in Japanese yen, and 
a significant portion of Display Technologies and Specialty Materials segment manufacturing costs are denominated in Japanese Yen, Korean 
won,  New Taiwan  dollar  and  Chinese  yuan,  management  believes  it  is  important  to  understand  the  impact  on  earnings  of  translating  these 
currencies into U.S. dollars. Presenting results on a constant-currency basis mitigates the translation impact and allows management to evaluate 
performance period over period, analyze underlying trends in our businesses, and establish operational goals and forecasts.

Constant-yen: As of January 1, 2018, we use an internally derived management rate of ¥107, which is closely aligned to our current yen portfolio of 
foreign currency hedges, and have recast all periods presented based on this rate to effectively remove the impact of changes in the Japanese yen.

Constant-won: As of January 1, 2018, we use an internally derived management rate of ₩1,175, which is closely aligned to our current won portfolio 
of foreign currency hedges, and have recast all periods presented based on this rate.

Constant-yuan: In January 2018, we began presenting results of the Display Technologies and Specialty Materials segments on a constant-yuan 
basis to mitigate the translation impact of this currency on these segments. We use an internally derived management rate of yuan 6.7, which is 
closely aligned to our current yuan portfolio of foreign currency hedges and consistent with historical prior period averages.

Constant-Taiwan dollar: In January 2018, we began presenting results of the Display Technologies and Specialty Materials segments on a constant-
Taiwan dollar basis  to mitigate  the  translation impact of  this currency on  these segments. We use an internally derived management rate of 
New Taiwan  dollar  31,  which  is  closely  aligned  to  our  current  New Taiwan  dollar  portfolio  of  cash  flow  hedges,  and  approximates  the  10-year 
historical average of the currency.

(2)  Translation  (gain)  loss  on  Japanese  yen-denominated  debt:  We  have  excluded  the  gain  or  loss  on  the  translation  of  our  yen-denominated 

debt to U.S. dollars.

(3)  Translated  earnings  contract  (gain)  loss: We  have  excluded  the  impact  of  the  realized  and  unrealized  gains  and  losses  of  our  Japanese  yen, 
South  Korean  won,  Chinese  yuan  and  New Taiwan  dollar-denominated  foreign  currency  hedges  related  to  translated  earnings,  as  well  as  the 
unrealized gains and losses of our euro and British pound-denominated foreign currency hedges related to translated earnings.

(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: For 2018, this amount primarily relates to the preliminary IRS audit settlement offset by 
changes in judgment about the realizability of certain deferred tax assets. For 2017, this amount represents the removal of discrete adjustments 
(e.g., changes in tax law, other than those of the 2017 Tax Act which are set forth separately, and 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 that reflect developments in commercial litigation, intellectual property disputes 

and other legal matters.

(7)  Restructuring, impairment and other charges: This amount includes restructuring, impairment and other charges, as well as other expenses which 

are not related to continuing operations and are not classified as restructuring expense.

(8)  Equity in earnings of affiliated companies: These adjustments relate to costs not related to continuing operations of our affiliated companies, such 

as restructuring, impairment and other charges and settlements, or modifications, 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: Defined benefit pension mark-to-market 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  resulting  from  the  2017 Tax  Act:  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 credit 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 pharmaceutical technologies, auto 
glass,  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.

2018 vs. 2017
Display Technologies segment net sales increased $139 million compared 
to the prior year. Total display glass market volume was up in 2018. Our 
volume growth in this market more than offset price declines on a year-
over-year basis. 2018 was the best pricing environment in more than a 
decade, achieving the important milestone of mid-single digit year-over-
year declines during the second half of the year.

Net income decreased by $53 million, or 6%, mainly driven by the costs of 
expanding Gen 10.5 capacity, ramping production and rebuilding tanks 
for fleet optimization during the first half of the year. 

2017 vs. 2016
Net sales decreased by $151 million, or 5%, in the year ended December 31, 
2017, when compared to the same period in 2016, driven by price declines 
of  approximately  10%,  partially  offset  by  an  increase  in  volume  in  the 
mid-single digits in percentage terms. 

Net income decreased by $65 million, or 7%, driven by the following items:

• The impact of price declines of approximately 10%; 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; and 

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

Outlook:

For full-year 2019, Corning expects the display glass market to grow by a 
mid-single digit percentage, consistent with 2018. The Company expects 
Corning’s volume  to grow faster  than  the market due  to expansion of 
our Gen 10.5 manufacturing capacity in China. 2018 was the best pricing 
environment in more than a decade achieving the important milestone 
of mid-single digit year-over-year declines in the second half of the year. 
We expect our full year 2019 price declines to improve further to a mid-
single digit percentage and to be even better than they were in 2018.

Liquidity and Capital Resources

Financing and Capital Structure
The following items discuss Corning’s financing and changes in capital 
structure during 2018 and 2017:

2018

In  the  second  quarter  of  2018,  Corning  issued  ¥65.5  billion  Japanese 
yen-denominated  debt  securities  in  tranches  of  7,  10  and  12  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 $596 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. The  net  proceeds  of 
$596 million will be used for general corporate purposes.

2017

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. 
The  net  proceeds  of  $700  million  were  made  available  for  general 
corporate purposes.

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.

In the third quarter of 2018, Corning amended and restated its revolving 
credit  agreement  (the  “Revolving  Credit  Agreement”).  The  Revolving 
Credit Agreement provides a $1.5 billion unsecured multi-currency line 
of  credit  and  expires  August  15, 2023. The  Revolving  Credit  Agreement 
includes affirmative and negative covenants with which Corning must 
comply,  including  a  leverage  (debt  to  capital  ratio)  financial  covenant. 
The required leverage ratio is a maximum of 60%. 

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 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  2018,  Corning  issued  $900  million  U.S.  dollar-
denominated unsecured long-term notes in  tranches of 19, 30, and 50 
years. The net proceeds of $889 million will be used for general corporate 
purposes. We  can  redeem  these  notes  at  any  time,  subject  to  certain 
terms and conditions.

In the fourth quarter of 2018, Corning redeemed $250 million of 6.625% 
Notes due 2019, paying a nominal call premium. The bond redemption 
incurred an insignificant loss during the fourth quarter of 2018.

Common Stock Dividends
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. 

CORNING INCORPORATED - 2018 Annual Report

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

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. 

On  February  6,  2019,  Corning’s  Board  of  Directors  declared  an  11.1% 
increase  in  the  Company’s  quarterly  common  stock  dividend,  which 
increased the quarterly dividend from $0.18 to $0.20 per share of common 
stock, beginning with the dividend paid in the first quarter of 2019. This 
increase marks the eighth 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, 2018, the preferred stock has not been converted, and none 
of the anti-dilution provisions have been triggered. 

Customer Deposits 
As  of  December  31,  2018  and  2017,  Corning  had  customer  deposits  of 
approximately $1.0 billion and $0.4 billion, respectively. The majority of 
these represent non-refundable cash deposits for customers  to secure 
rights  to  an  amount  of  glass  produced  by  Corning  under  long-term 
supply agreements. The duration of these long-term supply agreements 
ranges  up  to  ten  years.  As  glass  is  shipped  to  customers,  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. No credit memoranda were 
issued in 2018 and 2017.

Capital Spending
Capital spending totaled $2.2 billion in 2018, an increase of approximately 
$0.4  billion  when  compared  to  2017,  driven  by  expansions  related  to 
the  Gen  10.5  glass  manufacturing  facilities  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 2019 capital expenditures to 
be slightly more than $2.0 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

2018 vs. 2017 

Net cash provided by operating activities increased by $915 million in the 
year ended December 31, 2018 when compared to the same period last 
year, primarily driven by an increase in customer incentives and deposits 
of  $600  million.  Favorable  movements  of  $189  million  in  accounts 
payable and other current liabilities were driven largely by an increase in 
accounts payable in  the Optical Communications segment and higher 
current  liabilities  in  the  Specialty  Materials  segment.  Cash  received 
of  $104  million,  which  represents  the  excess  of  the  fair  value  of  the 
contingent  consideration  asset  related  to  the  acquisition  of  Samsung 
Corning Precision Materials (refer to Note 14 (Fair Value Measurements) 
to  the  Consolidated  Financial  Statements  for  additional  information), 
also increased cash provided by operating activities. 

Net cash used in investing activities increased by $1,177 million in the year 
ended December 31, 2018, when compared to the same period last year, 
driven by increased capital expenditures of $438 million due to capacity 
expansions,  increased  acquisition  spending  of  $671  million  and  lower 
gains  realized  on  translated  earnings  contracts  of  $162  million.  Cash 
received of $196 million, which represents the original fair value of the 
contingent  consideration  asset  related  to  the  acquisition  of  Samsung 
Corning Precision Materials (refer to Note 14 (Fair Value Measurements) 
to  the  Consolidated  Financial  Statements  for  additional  information), 
partially offset the net cash used in investing activities.

Net  cash  used  in  financing  activities  in  the  year  ended  December  31, 
2018 increased by $371 million when compared to the same period last 
year, driven by higher debt repayments, up $377 million and a decrease of 
$228 million for proceeds from the exercise of stock options. A decrease 
of  $225  million  in  share  repurchases  partially  offset  the  negative  cash 
impact of these items.

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 12 (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.

30 CORNING INCORPORATED - 2018 Annual Report

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

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.

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, 2018,  this  plan  accounted  for  76% 
of  our  consolidated  defined  benefit  pension  plans’  projected  benefit 
obligation and 85% of the related plans’ assets.

In  2018,  we  made  voluntary  cash  contributions  of  $105  million  to 
our  domestic  defined  benefit  pension  plan  and  $12  million  to  our 
international  pension  plans.  In  2017,  we  made  no  voluntary  cash 
contributions  to  our  domestic  defined  benefit  pension  plan  and 
$29  million  to  our  international  pension  plans.  During  2019,  we 
anticipate making cash contributions of $75 million to our U.S. qualified 
pension plan and $31 million to our international pension plans.

Management Assessment of Liquidity
We ended the fourth quarter of 2018 with approximately $2.4 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, 2018, 
approximately  56%  of  the  consolidated  amount  was  held  outside  of 
the United States. During 2018, the Company distributed approximately 
$2.2  billion  in  cash  from  foreign  subsidiaries  to  the  U.S.  parent. There 
were 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.  As  of  December  31,  2018, 
there are no interest rate swaps outstanding.

Corning  also  has  a  commercial  paper  program  pursuant  to  which  we 
may  issue  short-term,  unsecured  commercial  paper  notes  up  to  a 
maximum  aggregate  principal  amount  outstanding  at  any  one  time 

of  $1.5  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  Revolving  Credit  Agreement  is  available  to 
support obligations under the commercial paper program, if needed. At 
December 31, 2018 Corning did not have outstanding commercial paper.

Share Repurchases
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.

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

During 2018, Corning repurchased 74.8 million shares for approximately 
$2.2 billion through open market repurchases under the 2016 and 2018 
Repurchase Programs.

Refer  to  Note  15  (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 2019 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 to fund operations, acquisitions, capital expenditures, scheduled 
debt repayments, dividend payments and share repurchase programs.

Our  Revolving  Credit  Agreement  includes  affirmative  and  negative 
covenants  with  which  we  must  comply,  including  a  leverage  (debt 
to  capital  ratio)  financial  covenant.  The  required  leverage  ratio  is  a 
maximum of 60%. At December 31, 2018, our leverage using this measure 
was approximately 30%. As of December 31, 2018, we were in compliance 
with this 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, 2018, 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  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
Corning has hedged 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, 2018, 2017 and 2016, we recorded 
pre-tax net losses of $96 million, $201 million and $459 million related 
to  changes  in  the  fair  value  of  these  instruments.  Included  in  these 
amounts are realized gains of $64 million, $268 million and $207 million, 
respectively. The gross notional value outstanding for these instruments 
which  hedge  our  exposure  to  the  Japanese  yen  at  December  31,  2018, 
2017 and 2016 was $11.6 billion, $13 billion and $14.9 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 year ended 
December 31, 2018, we recorded a pre-tax net loss of $26 million, and in 

the  years  ended  December  31,  2017  and  2016,  we  recorded  pre-tax  net 
gains of $95 million and $7 million, respectively, related to changes in the 
fair value of these instruments. Included in these amounts is a realized 
gain  of  $46  million,  and  realized  losses  of  $1  million  and  $7  million, 
respectively. These instruments had a gross notional value outstanding 
at  December  31,  2018,  2017  and  2016  of  $0.1  billion,  $0.8  billion  and 
$1.2 billion, respectively.

We have entered into a portfolio average rate forwards to hedge against 
our euro translation exposure. In the years ended December 31, 2018, 2017 
and 2016, we recorded a pre-tax gain of $43 million, a net pre-tax loss of 
$40 million, and a net pre-tax gain of $15 million, respectively. Included 
in these amounts are realized losses of $14 million and $2 million, and a 
realized gain of $1 million, respectively. At December 31, 2018, the euro-
denominated average rate instruments had a gross notional amount of 
$1.2 billion, and at 2017 and 2016, a gross notional amount of $0.3 billion.

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

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 12 (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 and are not consolidated. 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.

Environment

Refer to Item 3. Legal Proceedings or Note 12 (Commitments, Contingencies and Guarantees) to the Consolidated Financial Statements for information.

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.

Acquired assets and liabilities
We  account  for  the  acquisition  of  a  business  using  the  purchase 
method  of  accounting,  which  requires  us  to  estimate  the  fair  values 
of  the  assets  acquired  and  liabilities  assumed.  This  includes  acquired 
intangible  assets  such  as  customer-related  intangibles  and  patents, 
fixed assets and inventories. Liabilities assumed may include litigation 
and other contingency reserves existing at the time of acquisition and 

require  judgment  in  ascertaining  the  related  fair  values.  Independent 
appraisals may be used to assist in the determination of the fair value 
of certain assets and liabilities. Such appraisals are based on significant 
estimates  provided  by  us,  such  as  forecasted  revenues  and  profits 
utilized  in  determining  the  fair  value  of  contract-related  acquired 
intangible assets or liabilities. Significant changes in assumptions and 
estimates  subsequent  to  completing  the  allocation  of  the  purchase 
price  to  the  assets  and  liabilities  acquired,  as  well  as  differences  in 
actual  and  estimated  results  could  result  in  impacts  to  our  financial 
results. Additional information related to the acquisition date fair value 
of acquired assets and liabilities obtained during the allocation period, 
not to exceed one year, may result in changes to the recorded values of 
acquired assets and liabilities, resulting in an offsetting adjustment to 
the goodwill associated with the business acquired.

CORNING INCORPORATED - 2018 Annual Report

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

In 2018 we acquired CMD from 3M in a business combination. Included 
in  the  acquisition  were  other  intangible  assets  consisting  primarily 
of  $434  million  of  customer  relationships  and  $91  million  of  other 
intangibles that are amortized over the weighted average useful life of 
approximately  14  and  11  years,  respectively.  The  customer  relationship 
intangible  asset  was  valued  using  the  Multi-Period  Excess  Earnings 
Valuation Method, which is an income approach method that estimates 
fair value of revenue based upon  the present value of cash flows  that 
are  expected  to  be  generated  from  the  acquired  customer  base.  Key 
assumptions  used  in  this  valuation  include  a  discount  rate  of  12.5%, 
revenue growth rates in the range of 0% to 3% and a customer attrition 
rate of 6%.

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

At  December  31,  2018  and  December  31,  2017,  the  carrying  value  of 
precious metals was higher  than  the fair market value by $719 million 
and $711 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. Goodwill is tested for impairment at the reporting 
unit  level.  A  reporting  unit  is  equivalent  to  an  operating  segment  or 
a  component  of  an  operating  segment  which  constitutes  a  business 
and  for  which  discrete  financial  information  is  regularly  reviewed 
by  segment  management.  An  impairment  loss  generally  would  be 
recognized  when  the  carrying  amount  of  a  reporting  unit’s  net  assets 
exceeds the estimated fair value of the reporting unit.

34 CORNING INCORPORATED - 2018 Annual Report

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

Corning  has  recorded  goodwill  in  the  Display  Technologies,  Optical 
Communications,  Specialty  Materials,  Life  Sciences  and  All  Other 
operating  segments.  Each  of  these  operating  segments  is  a  separate 
reporting unit; however, Specialty Materials and All Other are each made 
up of two separate reporting units. 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 a 
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  assessment  is  performed  by  assessing  various  factors 
to determine whether it is more likely than not that the fair value of a 
reporting unit is less than its carrying amount. These factors include, but 
are not limited to, changes in macroeconomic conditions, industry and 
market considerations, cost factors, overall financial performance, other 
relevant entity-specific events, or a sustained decrease in share price.

In 2018, we performed a quantitative goodwill impairment assessment 
in  addition  to  assessing  the  qualitative  factors  each  quarter.  Our 
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 present value using an 
appropriate discount rate. Our estimates are based upon our historical 
experience, our current knowledge from our commercial relationships, 
and available external information about future trends. The quantitative 
assessment  requires  the  exercise  of  significant  judgment,  including 
judgment  about  appropriate  discount  rates,  growth  rates  and  the 
timing of expected future cash flows of the respective reporting unit.

The  quantitative  assessment  of  goodwill  resulted  in  fair  values 
significantly exceeding the carrying values for all of our reporting units. 
We also performed a sensitivity analysis, using a range between 7-10% for 
the discount rate and 0%-3% for the growth rate, which had no material 
impact on our results. Based on the quantitative test performed in 2018, 
no goodwill impairment was required.

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.

As  of  December  31,  2018,  Corning  has  completed  its  analysis  of  the 
impact of the 2017 Tax Act as required by SAB 118.

Beginning in 2018, Corning will indefinitely reinvest the foreign earnings 
of: (1) any of its subsidiaries located in jurisdictions where Corning lacks 
the  ability  to  repatriate  its  earnings,  (2)  any  of  its  subsidiaries  where 
Corning’s intention is to reinvest those earnings in operations, (3) legal 
entities  for  which  Corning  holds  a  non-controlling  interest,  (4)  any 
subsidiaries  with  an  accumulated  deficit  in  earnings  and  profits  and 
(5) any subsidiaries which have a positive earnings and profits balance 
but for which the entity lacks sufficient local statutory earnings or stock 
basis from which to make a distribution.

Under the 2017 Tax Act, a company can make a policy election to account 
for the tax on GILTI as a period cost or to recognize deferred tax assets 
and  liabilities  when  basis  differences  exist  that  are  expected  to  affect 
the  amount  of  GILTI  inclusion  upon  reversal.  Corning  has  elected  to 
account for the GILTI provisions as a period cost.

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,  Chinese  yuan  and  British  pound. These 
contracts are not designated as accounting hedges, and changes in fair 
value are recorded in earnings in the translated earnings contract loss, 
net  line  of  the  Consolidated  Statements  of  Income  (Loss).  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 14 (Fair Value Measurements) to the Consolidated Financial 
Statements for additional information.

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

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 
on  demographic  assumptions 
retirements,  mortality, 
turnover  and  plan  participation. While  management  believes  that  the 
assumptions  used  are  appropriate,  differences  in  actual  experience  or 
changes  in  assumptions  may  affect  Corning’s  employee  pension  and 
other postretirement obligations, and current and future expense.

including 

Costs  for  our  defined  benefit  pension  plans  consist  of  two  elements: 
1)  on-going  costs  recognized  quarterly,  which  are  comprised  of  service 
and interest costs, expected return on plan assets and amortization of 
prior service costs; and 2) mark-to-market gains and losses outside of the 
corridor, where the corridor is equal to 10% of the greater of the benefit 
obligation or the market-related value of plan assets at the beginning of 
the year, which are recognized annually in the fourth quarter of each year. 
These  gains  and  losses  result  from  changes  in  actuarial  assumptions 
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  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.

On  January  1, 2018,  Corning  adopted  ASU  No.  2017-07,  Compensation 
Retirement  Benefits  (Topic  715):  Improving  the  Presentation  of  Net 
Periodic  Pension  Cost  and  Net  Periodic  Post-Retirement  Benefit 
Cost,  which  presents  the  service  cost  component  with  other  current 
compensation costs in operating income. The remaining components 
are included in  the line item Other expense, net, in  the Consolidated 
Statements  of 
the  practical 
expedient  as  the  estimation  basis  for  applying  the  retrospective 
presentation requirements.

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

The following information illustrates the sensitivity to a change in certain assumptions for U.S. pension plans:

Change in assumption

25 basis point increase in each spot rate
25 basis point decrease in expected return on assets
25 basis point increase in expected return on assets

pre-tax pension expense

- 2 million
+ 2 million
+ 7 million
- 7 million

Effect on 
December 31, 2018 PBO
+ 91 million
- 87 million

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, 2018, a 25 basis point decrease in each spot 
rate would decrease stockholders’ equity by $112 million before tax, and 
a 25 basis point increase in each spot rate would increase stockholders’ 
equity by $107 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.

Revenue recognition
The  Company  recognizes  revenue  when  all  performance  obligations 
under  the  terms  of  a  contract  with  our  customer  are  satisfied,  and 
control of the product has been transferred to the customer. If customer 
acceptance clauses are present and it cannot be objectively determined 
that  control  has  been  transferred,  revenue  is  only  recorded  when 
customer acceptance is received and all performance obligations have 
been satisfied. Sales of goods typically do not include multiple product 
and/or  service  elements.  Corning  also  has  contractual  arrangements 
with  certain  customers  in  which  we  recognize  revenue  over  time. 
The  performance  obligations  under  these  contracts  generally  require 
services  to  be  performed  over  time,  resulting  in  either  a  straight-line 

amortization method or an input method using incurred and forecasted 
expense  to  predict  revenue  recognition  patterns  which  follows 
satisfaction of the performance obligation.

On  January  1,  2018,  we  adopted  Accounting  Standards  Update  (“ASU”) 
No. 2014-09 ASC (Topic 606), Revenue from Contracts with Customers, 
and applied the modified retrospective method of accounting to those 
contracts  which  were  not  completed  as  of  January  1,  2018.  Results  for 
reporting  periods  beginning  after  January  1,  2018  are  presented  under 
Topic  606,  while  prior  period  amounts  are  not  adjusted  and  continue 
to  be  reported  in  accordance  with  our  historic  accounting  under  ASC 
Topic  605 “Revenue  Recognition”.  Because  the  impact  of  adopting  the 
standard on Corning’s financial statements was immaterial, we have not 
made an adjustment to opening retained earnings.

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  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, 
2018,  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 $1.1 billion compared to $1.4 billion at December 31, 2017. 
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 
$1.0 billion compared to $1.3 billion at December 31, 2017. 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  on  the  assets,  liabilities  and 
future transactions being hedged.

Interest Rate Risk Management 
To  manage  interest  rate  exposure,  the  Company,  from  time  to  time, 
enters into interest rate derivatives agreements. In  the second quarter 
of 2018, the Company entered into Treasury rate lock agreements with 
notional  amounts  of  $300  million  to  hedge  against  the  variability  in 
cash flows due to changes in the benchmark interest rate related to an 
anticipated  debt  issuance.  The  instruments  were  designated  as  cash 
flow hedges, and were settled with $16 million received on October 31, 
2018 concurrent with the debt issuance.

38 CORNING INCORPORATED - 2018 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. 

Corning acquired substantially all of CMD during 2018, and management 
excluded CMD from its assessment of the effectiveness of the Company’s 
internal control over financial reporting as of December 31, 2018. CMD’s 
internal control over financial reporting is associated with less than 1% 
of total assets and 2% of net sales included in the consolidated financial 
statements of the Company and its subsidiaries as of and for the year 
ended December 31, 2018. 

Based on this evaluation, management concluded that Corning’s internal 
control  over  financial  reporting  was  effective  as  of  December  31,  2018. 
The  effectiveness  of  Corning’s  internal  control  over  financial  reporting 
as of December 31, 2018, has been audited by PricewaterhouseCoopers 
LLP, an independent registered public accounting firm, as stated in their 
report which is included herein.

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

Opinions on the Financial Statements and Internal Control over 
Financial Reporting

We  have  audited  the  accompanying  consolidated  balance  sheets  of 
Corning  Incorporated  and  its  subsidiaries  as  of  December  31,  2018 
and  2017,  and  the  related  consolidated  statements  of  income  (loss), 
comprehensive  income,  changes  in  shareholders’  equity  and  cash 
flows for each of the three years in the period ended December 31, 2018, 
including  the  related  notes  and  schedule  of  valuation  and  qualifying 
accounts  for  each  of  the  three  years 
in  the  period  ended 
Item  15  (a)(2)  (collectively 
December  31,  2018  appearing  under 
referred  to  as  the “consolidated  financial  statements”).  We  also  have 
audited  the  Company’s  internal  control  over  financial  reporting  as  of 
December  31,  2018,  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,  2018  and  2017,  and  the  results  of  its 
operations and its cash flows for each of the three years in the period 
ended  December  31,  2018  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, 2018, 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.

As  described  in  Management’s  Annual  Report  on  Internal  Control 
over  Financial  Reporting,  management  has  excluded  CMD  from 
its  assessment  of  internal  control  over  financial  reporting  as  of 
December  31,  2018  because  it  was  acquired  by  the  Company  in  a 
purchase  business  combination  during  2018.  We  have  also  excluded 
CMD  from  our  audit  of  internal  control  over  financial  reporting.  CMD 
is a wholly-owned business whose total assets and net sales excluded 
from management’s assessment and our audit of internal control over 
financial  reporting  represent  less  than  1%  and  2%,  respectively,  of  the 
related consolidated financial statement amounts as of and for the year 
ended December 31, 2018.

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.

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,  display  televisions, 
information  display  applications;  carrier  network  and 
and  other 
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.

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, we use the fair value method to account 
for the investments if readily determinable fair values are available. For 
the investments without readily determinable fair values, we measure 
them at cost minus impairment, if any, plus or minus changes resulting 
from observable price changes in orderly transactions for the identical 
or a similar investment.

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

On  January  1,  2018,  we  adopted  Accounting  Standards  Update  (“ASU”) 
No. 2014-09 ASC (Topic 606), Revenue from Contracts with Customers, 
and applied the modified retrospective method of accounting to those 
contracts  which  were  not  completed  as  of  January  1,  2018.  Results  for 
reporting  periods  beginning  after  January  1,  2018  are  presented  under 
Topic  606,  while  prior  period  amounts  are  not  adjusted  and  continue 
to  be  reported  in  accordance  with  our  historic  accounting  under  ASC 
Topic  605 “Revenue  Recognition”.  Because  the  impact  of  adopting  the 
standard on Corning’s financial statements was immaterial, we have not 
made an adjustment to opening retained earnings.

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. The current assessment indicates 

that  the  impact  of  adoption  to  Corning’s  financial  statements  will  be 
an  adjustment  to  2019  beginning  retained  earnings  of  approximately 
$230  million  relating  to  timing  of  revenue  recognition  for  open 
performance  obligations  as  measured  at  January  1,  2019  under  the 
new standard.

On  January  1,  2018,  Corning  adopted  ASU  2016-15,  Statement  of  Cash 
Flows  (Topic  230):  Classification  of  Certain  Cash  Receipts  and  Cash 
Payments,  which  refines  the  classification  of  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. The impact of adopting the standard 
on Corning’s financial statements was not material.

On  January  1,  2018,  we  adopted  ASU  No.  2017-07,  Compensation—
Retirement  Benefits  (Topic  715):  Improving  the  Presentation  of  Net 
Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The 
service  cost  component  of  net  periodic  pension  and  postretirement 
benefit  cost  is  presented  with  other  current  compensation  costs  in 
operating income. The remaining components are included in  the line 
item  Other  expense,  net,  in  the  consolidated  statements  of  income 
(loss).  Corning  has  applied  the  practical  expedient  which  permits  it 
to  use  the  amounts  disclosed  in  its  pension  and  other  postretirement 
benefit  plan  note  for  the  prior  comparative  periods  as  the  estimation 
basis  for  applying  the  retrospective  presentation  requirements.  The 
impact of adopting the standard on Corning’s financial statements was 
not material.

Certain  prior  year  amounts  have  been  reclassified  to  conform  to 
the  current  year’s  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 held 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 5 (Investments) to the Consolidated Financial Statements 
for additional information.

46 CORNING INCORPORATED - 2018 Annual Report

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  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
The  majority  of  our  revenues  are  generated  by  delivery  of  products  to 
our customers and recognized at a point in time based on our evaluation 
of  when  the  customer  obtains  control  of  the  products.  Revenue  is 
recognized  when  all  performance  obligations  under  the  terms  of  a 
contract  with  our  customer  are  satisfied,  and  control  of  the  product 
has  been  transferred  to  the  customer.  If  customer  acceptance  clauses 
are  present  and  it  cannot  be  objectively  determined  that  control  has 
been  transferred, revenue is only recorded when customer acceptance 
is received and all performance obligations have been satisfied. Sales of 
goods typically do not include multiple product and/or service elements.

Revenue  is  measured  as  the  amount  of  consideration  we  expect  to 
receive  in  exchange  for  transferring  goods  or  providing  services.  Sales 
tax, value-added tax, and other taxes we collect concurrent with revenue-
producing activities are excluded from revenue. Incidental contract costs 
that are not material in the context of the delivery of goods and services 
are recognized as expense.

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 over time. The performance 
obligations  under  these  contracts  generally  require  services  to  be 
performed  over  time,  resulting  in  either  a  straight-line  amortization 
method or an input method using incurred and forecasted expense to 
predict  revenue  recognition  patterns  which  follows  satisfaction  of  the 
performance obligation.

Research and Development Costs
Research  and  development  costs  are  charged  to  expense  as  incurred. 
in  2018, 
Research  and  development  costs  totaled  $807  million 
$689 million in 2017 and $637 million in 2016.

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 

Notes to Consolidated Financial Statements

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 a net loss of $43 million and a net gain of $20 million for 
foreign currency  transaction activity for  the years ended December 31, 
2018 and 2017, respectively. These amounts were recorded in the line item 
Other expense, net in the Consolidated Statements of Income (Loss).

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  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  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,  2018,  there 
were  approximately  62  million  unissued  common  shares  available  for 
future grants authorized 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.

Total  share-based  compensation  expense  was  $51  million,  $46  million 
and  $42  million  for  the  years  ended  December  31,  2018,  2017  and 
2016,  respectively.  The  income  tax  benefit  realized  from  share-based 
compensation  was  not  significant  for  the  years  ended  December  31, 
2018, 2017 and 2016. Refer to Note 4 (Income Taxes) to the Consolidated 
Financial Statements for additional information.

Stock Options
Corning’s stock option plans provide non-qualified and incentive stock 
options  to  purchase  authorized  but  unissued  common  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.

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.

Notes to Consolidated Financial Statements

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.

The following inputs were used for the valuation of option grants under our stock option plans:

Expected volatility

Weighted-average volatility

Expected dividends

Risk-free rate

Expected term (in years)

Pre-vesting departure rate

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.

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 2018, 2017 and 2016, 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 
obligations in establishing a provision for those costs. Where no amount 
within  a  range  of  estimates  is  more  likely  to  occur  than  another,  the 
minimum amount is accrued. When future liabilities are determined to 
be  reimbursable  by  insurance  coverage,  an  accrual  is  recorded  for  the 
potential liability and a receivable is recorded related  to  the insurance 
reimbursement when reimbursement is virtually certain.

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

Notes to Consolidated Financial Statements

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

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.

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 7 (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 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.

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 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.

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 
and the differences between actual and expected return on plan assets. 
Any interim remeasurements triggered by a curtailment, settlement or 
significant plan changes, as well as any true-up to the annual valuation, 
are recognized as a mark-to-market adjustment in the quarter in which 
such event occurs.

Costs  for  our  postretirement  benefit  plans  consist  of  on-going  costs 
recognized  quarterly,  and  are  comprised  of  service  and  interest  costs, 
amortization of prior service costs and amortization of actuarial gains 
and losses. We recognize  the actuarial gains and losses resulting from 
changes  in  actuarial  assumptions  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  11  (Employee  Retirement  Plans)  to  the  Consolidated 
Financial Statements for additional detail.

CORNING INCORPORATED - 2018 Annual Report

Notes to Consolidated Financial Statements

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

The  effective  income  tax  rate  reflects  our  assessment  of  the  ultimate 
outcome  of  tax  audits.  In  evaluating  the  tax  benefits  associated  with 
our various tax filing positions, we record a tax benefit for uncertain tax 
positions using the highest cumulative tax benefit that is more likely than 
not to be realized. Adjustments are made to our liability for unrecognized 
tax benefits in the period in which we determine the issue is effectively 
settled with the tax authorities, the statute of limitations expires for the 
return containing  the  tax position or when new information becomes 
available. Our liability for unrecognized tax benefits, including accrued 
penalties and interest, is included in other accrued liabilities and other 
long-term liabilities on our consolidated balance sheets and in income 
tax expense in our Consolidated Statements of Income (Loss).

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.

Beginning in 2018, Corning will indefinitely reinvest the foreign earnings 
of: (1) any of its subsidiaries located in jurisdictions where Corning lacks 
the  ability  to  repatriate  its  earnings,  (2)  any  of  its  subsidiaries  where 
Corning’s intention is to reinvest those earnings in operations, (3) legal 
entities  for  which  Corning  holds  a  non-controlling  interest,  (4)  any 
subsidiaries  with  an  accumulated  deficit  in  earnings  and  profits  and 
(5) any subsidiaries which have a positive earnings and profits balance 
but for which the entity lacks sufficient local statutory earnings or stock 
basis from which to make a distribution.

A  company  can  make  a  policy  election  to  account  for  the  tax  on  GILTI 
as a period cost or to recognize deferred tax assets and liabilities when 
basis differences exist that are expected to affect the amount of GILTI 
inclusion  upon  reversal.  Corning  has  elected  to  account  for  the  GILTI 
provisions as a period cost.

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  manage  the  mix  of  fixed  and  floating  rate  debt.  These 
financial exposures are managed in accordance with corporate policies 
and procedures.

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

New Accounting Standards
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  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. ASU 2016-02 may be applied with a modified 
retrospective approach with various practical expedients. The adoption 
of  ASU  2016-02  will  have  no  impact  to  retained  earnings  or  income. 
Upon  adoption  of  ASU  2016-02,  we  anticipate  recording  a  right-of-use 
asset  and  an  offsetting  lease  liability  of  approximately  $450  million. 
Adoption of the new standard is effective January 1, 2019.

50 CORNING INCORPORATED - 2018 Annual Report

In  February  2018,  the  FASB  issued  ASU  2018-02,  Income  Statement  - 
Reporting  Comprehensive  Income,  which  allows  for  reclassification 
from  accumulated  other  comprehensive  income  to  retained  earnings 
for  stranded  tax  effects  resulting  from  the  Tax  Cuts  and  Jobs  Act. 

ASU  2018-02  is  effective  for  annual  reporting  periods  beginning  after 
December 15, 2018, and interim periods within those annual periods. We 
have determined that the impact of this standard will not be material. 
Adoption of the new standard is effective January 1, 2019.

Notes to Consolidated Financial Statements

2.  Revenue

On January 1, 2018, we adopted ASC Topic 606 “Revenue from Contracts 
with  Customer”,  and  all  related  amendments,  using  the  modified 
retrospective  method  applied  to  those  contracts  which  were  not 
completed as of January 1, 2018. Results for reporting periods beginning 
after January 1, 2018 are presented under Topic 606, while prior period 
amounts  are  not  adjusted  and  continue  to  be  reported  in  accordance 
with our historic accounting under ASC Topic 605 “Revenue Recognition”.

We have determined that the impact of transition to the new standard 
is immaterial to our revenue recognition model since the majority of our 
recognition is based on point in time transfer of control. Accordingly, we 
have not made any adjustment to opening retained earnings.

Product Revenue (Point in Time)
The  majority  of  our  revenues  are  generated  by  delivery  of  products  to 
our customers and recognized at a point in time based on our evaluation 
of  when  the  customer  obtains  control  of  the  products.  Revenue  is 
recognized  when  all  performance  obligations  under  the  terms  of  a 
contract  with  our  customer  are  satisfied,  and  control  of  the  product 
has  been  transferred  to  the  customer.  If  customer  acceptance  clauses 
are  present  and  it  cannot  be  objectively  determined  that  control  has 
been  transferred, revenue is only recorded when customer acceptance 
is received and all performance obligations have been satisfied. Sales of 
goods typically do not include multiple product and/or service elements.

Revenue  is  measured  as  the  amount  of  consideration  we  expect  to 
receive  in  exchange  for  transferring  goods  or  providing  services.  Sales 
tax, value-added tax, and other taxes we collect concurrent with revenue-
producing activities are excluded from revenue. Incidental contract costs 
that are not material in the context of the delivery of goods and services 
are recognized as expense.

Our revenues by product category are as follows (in millions):

Display products

Telecommunication products

Specialty glass products

Environmental substrate and filter products

Life science products

All Other

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.  Product  warranty 
liabilities were not material at December 31, 2018 and December 31, 2017.

Other Revenue (Over Time)
Corning’s over time revenues are mainly related to Telecommunications 
products, and are comprised of design, installation, training and software 
maintenance  services.  The  performance  obligations  under  these 
contracts generally require services to be performed over time, resulting 
in either a straight-line amortization method or an input method using 
incurred and forecasted expense to predict revenue recognition patterns 
which  follows  satisfaction  of  the  performance  obligation.  Corning’s 
other revenue is inconsequential to our results.

Revenue Disaggregation Table
The  following  table  shows  revenues  by  major  product  categories, 
similar  to  our  reportable  segment  disclosure.  Within  each  product 
category, contract terms, conditions and economic factors affecting the 
nature,  amount,  timing  and  uncertainty  around  revenue  recognition 
and  cash  flows  are  substantially  similar.  The  commercial  markets 
and  selling  channels  are  also  similar.  Except  for  an  inconsequential 
number  of  Telecommunications  products,  our  product  category 
revenues are recognized at point in time when control transfers to the 
customer. Prior year amounts are presented under the ASC 605 basis of 
revenue recognition.

Notes to Consolidated Financial Statements

Contract Assets and Liabilities
Contract assets, such as incremental costs to obtain or fulfill contracts, 
are  an  insignificant  component  of  Corning’s  revenue  recognition 
process. The majority of Corning’s cost of fulfillment as a manufacturer 
of products is classified as inventory, fixed assets and intangible assets, 
which are accounted for under the respective guidance for those asset 
types.  Other  costs  of  contract  fulfillment  are  immaterial  due  to  the 
nature of our products and their respective manufacturing processes.

Contract liabilities include deferred revenues, other advanced payments 
and customer deposits. Deferred revenue and other advanced payments 
are not significant to our operations and are classified as part of other 
accrued  liabilities  in  our  financial  statements.  Customer  deposits  are 
predominately  related  to  Display  products  and  are  classified  as  part 
of  other  accrued  liabilities  and  other  liabilities  as  appropriate,  and  are 
disclosed below.

ranges  up  to  ten  years.  As  glass  is  shipped  to  customers,  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. No credit memoranda were 
issued in 2018 and 2017.

Practical Expedients and Exemptions
We do not disclose the value of unsatisfied performance obligations for 
(i) contracts with an original expected length of one year or less and (ii) 
contracts for which we recognize revenue at  the amount  to which we 
have the right to invoice for services performed.

We  treat  shipping  and  handling  fees  as  a  fulfillment  cost  and 
not  as  a  separate  performance  obligation  under  the  terms  of  our 
revenue  contracts  due  to  the  perfunctory  nature  of  the  shipping  and 
handling obligations.

Customer Deposits
As  of  December  31,  2018  and  2017,  Corning  had  customer  deposits  of 
approximately $1.0 billion and $0.4 billion, respectively. The majority of 
these represent non-refundable cash deposits for customers  to secure 
rights  to  an  amount  of  glass  produced  by  Corning  under  long-term 
supply agreements. The duration of these long-term supply agreements 

Significant Customers
For  2018  and  2017,  no  customers  met  or  exceeded  10%  of  Corning’s 
consolidated  net  sales.  For  2016,  Corning’s  sales  to  Samsung  Display 
Co. Ltd., a customer of our Display Technologies and Specialty Materials 
segments, represented 11% of the Company’s consolidated net sales.

Effective income tax rate (benefit)

In December 2017,  the U.S. enacted  the 2017 Tax Act which resulted in 
significant changes for our financial results, including, but not limited 
to,  (1)  reducing  the  U.S.  federal  corporate  income  tax  rate  to  21%,  and 
(2)  imposing  a  one-time  toll  charge  on  certain  unrepatriated  earnings 
of foreign subsidiaries of U.S. companies  that had not been previously 
taxed in the U.S.

The 2017 Tax Act also established new tax provisions affecting our 2018 
results, including, but not limited to, (1) creating a new provision designed 
to  tax  GILTI;  (2)  generally  eliminating  U.S.  federal  taxes  on  dividends 
from foreign subsidiaries; (3) eliminating the corporate AMT; (4) creating 
the  BEAT;  (5)  establishing  a  deduction  for  FDII;  (6)  establishing  new 
limitations  on  deductible  interest  expense;  and  (7)  establishing  new 
limitations on deductibility of certain executive compensation.

Given  the  significant  complexity  of  the  2017  Tax  Act  and  the  lack  of 
clear  tax  and  accounting  regulatory  guidance  for  this  new  law,  the 
Securities  Exchange  Commission  issued  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 was required 
to  record  those  items  where  ASC  740  analysis  was  complete;  include 
reasonable  estimates  and  label  them  as  provisional  where  ASC  740 
analysis was incomplete; and if reasonable estimates could not be made, 
record items under the previous tax law. The measurement period, not 
to exceed one year, ended on the date the entity obtained, prepared, and 
analyzed the information that was needed to complete the accounting 
requirements under ASC Topic 740.

For  the  year  ended  December  31,  2018,  Corning’s  results  included  a 
worldwide  tax  provision  of  $437  million,  inclusive  of  tax  on  ongoing 
operations  of  $412  million  and  the  impacts  of  the  2017  Tax  Act  of 
$25  million.  The  impacts  of  the  2017  Tax  Act  include:  GILTI  tax  of 
$55 million, FDII benefit of $10 million, and a $20 million benefit related 
to  truing  up  the  toll  charge  and  our  measurement  of  U.S.  deferred 
taxes,  offset  by  the  recording  of  a  provision  related  to  lifting  our 
assertion of indefinite reinvestment on certain foreign earnings. As of 
December 31, 2018, Corning has completed its analysis of the impact of 
the 2017 Tax Act as required by SAB 118. The GILTI tax of $55 million was 
largely driven by the receipt of customer deposits. See Note 2 (Revenue) 
to these Consolidated Financial Statements for more information.

In response to the reduction of the U.S. Federal Corporate Tax Rate, the 
Company 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%. We recorded a provisional estimate of $347 million during 
2017. This was adjusted by an immaterial amount upon completion of 
our analysis for the year ended December 31, 2018.

We recorded a provisional expense of $1.1 billion for  the Toll Charge at 
year end 2017 on unrepatriated earnings of certain foreign subsidiaries 
that  were  previously  deferred. This  charge  was  reduced  by  $35  million 
upon completion of our analysis.

Notes to Consolidated Financial Statements

Corning  has  completed  its  analysis  on  the  impact  of  the  2017 Tax  Act 
on  its  assertion  regarding  its  indefinitely  reinvested  foreign  earnings. 
Corning  has  determined  that  it  will  no  longer  assert  indefinite 
asset  reinvestment  on  $15.4  billion  of  unremitted  foreign  earnings 
accumulated  prior  to  2018.  This  represents  approximately  94%  of 
Corning’s unremitted foreign earnings as of the end of 2017. Corning will 
continue  to  indefinitely  reinvest  the  remaining  6%  of  historic  foreign 
earnings as of December 31, 2017.

Beginning in 2018, Corning will indefinitely reinvest the foreign earnings 
of: (1) any of its subsidiaries located in jurisdictions where Corning lacks 
the  ability  to  repatriate  its  earnings,  (2)  any  of  its  subsidiaries  where 
Corning’s intention is to reinvest those earnings in operations, (3) legal 
entities  for  which  Corning  holds  a  non-controlling  interest,  (4)  any 
subsidiaries  with  an  accumulated  deficit  in  earnings  and  profits  and 
(5) any subsidiaries which have a positive earnings and profits balance 
but for which the entity lacks sufficient local statutory earnings or stock 
basis from which to make a distribution.

During 2018,  the Company distributed approximately $4.2 billion from 
foreign  subsidiaries  to  their  respective  U.S.  parent  companies.  There 
are  no  incremental  taxes  beyond  the  toll  charge  due  with  respect  to 
these distributions. As of December 31, 2018, Corning has approximately 
$1.5  billion  of  indefinitely  reinvested  foreign  earnings.  It  remains 
impracticable  to  calculate  the  tax  cost  of  repatriating  our  unremitted 
earnings which are considered indefinitely reinvested.

Under new guidance, a company can make a policy election to account 
for the tax on GILTI as a period cost or to recognize deferred tax assets 
and  liabilities  when  basis  differences  exist  that  are  expected  to  affect 
the  amount  of  GILTI  inclusion  upon  reversal.  Corning’s  has  elected  to 
account for the GILTI provisions as a period cost.

The  tax  effects  of  temporary  differences  and  carryforwards  that  gave  rise  to  significant  portions  of  the  deferred  tax  assets  and  liabilities  follows

54 CORNING INCORPORATED - 2018 Annual Report

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 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 change in the other accrued liabilities is largely driven 
by  the  payment  of  certain  withholding  taxes  and  reclassification  of  a 
portion of our deferred tax liability to deferred tax payable. Also, during 
2018, a benefit was recorded upon the release of valuation allowances 
on  deferred  tax  that  are  now  considered  realizable  outside  of  the  U.S. 
The amount of U.S. and foreign deferred tax assets that have remaining 
valuation  allowances  at  December  31, 2018  and  2017  was  $317  million 
and $456 million, respectively.

Notes to Consolidated Financial Statements

The 2017 Tax Act makes the following key changes to U.S. tax law which 
will  potentially  impact  Corning’s  deferred  tax  assets.  AMT  has  been 
eliminated.  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 $35 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 $22 million of foreign tax credit carryforwards that may be 
subject to these restrictions.

In 2018, we adopted ASU 2016-16, Improvements to Intra-Entity Transfers 
of  Assets  Other  Than  Inventory.  As  a  result,  cumulative  tax  benefits 
totaling  $5  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):

Balance at January 1

Additions based on tax positions related to the current year

Additions for tax positions of prior years

Reductions for tax positions of prior years

Settlements and lapse of statute of limitations

Balance at December 31

The additions for 2018 were primarily due  to a preliminary agreement 
with  the  IRS  to  resolve  its  2013-2014  audit.  Included  in  the  balance  at 
December  31,  2018,  2017  and  2016  are  $263  million,  $97  million  and 
$92 million, respectively, of unrecognized tax benefits that would impact 
our effective tax rate if recognized.

We  recognize  accrued 
interest  and  penalties  associated  with 
uncertain  tax  positions  as  part  of  tax  expense.  For  the  years  ended 
December  31,  2018,  2017  and  2016  the  amount  recognized  in  interest 
expense  and  accrued  for  the  payment  of  interest  and  penalties  were 
not material.

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

Corning  Incorporated  and  its  U.S.  subsidiaries  file  income  tax  returns 
on a combined, unitary or stand-alone basis in multiple state and local 
jurisdictions, which generally have statutes of limitations ranging from 
3 to 5 years. Various state income tax returns are currently in the process 
of examination or administrative appeal. We do not expect any material 
proposed adjustments from any of these audits.

Corning has reached a preliminary agreement with the IRS to resolve its 
2013-2014 audit. This preliminary agreement resulted in $172 million of 
additional tax expense in the first quarter of 2018, of which $12 million 
relates  to  interest  expense,  net  of  tax  benefit.  Corning  will  use  tax 
attributes to cover most of the tax expense. We expect to finalize this 
agreement during 2019.

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 10 years. The statute of limitations is closed 
through  the  following  years  in  these  major  jurisdictions:  Japan  (2011), 
Taiwan (2012) and South Korea (2012).

CPM  is  currently  appealing  certain  tax  assessments  and  tax  refund 
claims  for  tax  years  2006  through  2017.  The  Company  is  required  to 
deposit the disputed tax amounts with the South Korean government as 
a condition of its appeal of any tax 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 $425 million for the amount 
on deposit with the South Korean government.

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 held 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 received 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 has been profitable and recovered its 
equity as of December 31, 2018. The carrying value of the investment in 
HSG as of December 31, 2018 was $42 million and recorded in Investments.

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

6.  Acquisitions

During  2018,  Corning  acquired  substantially  all  of  CMD  in  two  cash 
transactions  totaling  $841  million.  On  June  1, 2018,  Corning  acquired  a 
manufacturing  facility  and  certain  other  assets  (collectively  referred 
to  as  “Purchased  Assets”)  for  $801  million.  The  Purchased  Assets 
constitute  a  business,  which  designs,  manufactures  and  markets  high 
bandwidth and optical fiber products. On December 3, 2018, as part of 

the acquisition of CMD, Corning acquired 100% of the German services 
company  for  $40  million.  The  acquisition  was  accounted  for  as  a 
business combination.

A summary of the preliminary allocation of the total purchase price to 
the net tangible and other intangible assets acquired, with the remainder 
recorded as goodwill based on fair value is as follows (in millions):

(1)  Amounts reflect measurement period adjustments.

(2) The goodwill recognized is deductible for U.S. income tax purposes. The goodwill was allocated to the Optical Communications segment.

Goodwill is related to the value of CMD’s product and customer portfolio 
and  its  combination  with  Corning’s  existing  optical  communications 
platform, as well as synergies and other intangibles that do not qualify 
for  separate  recognition.  Other  intangible  assets  consist  primarily 
of  $434  million  of  customer  relationships  and  $91  million  of  other 
intangibles that are amortized over the weighted average useful life of 
approximately 14 and 11 years, respectively. Acquisition-related costs of 
$18 million for the year ended December 31, 2018, included costs for legal, 
accounting, valuation and other professional services and were included 

in  selling,  general  and  administrative  expense  in  the  Consolidated 
Statements  of  Income.  Supplemental  pro  forma  information  was  not 
provided  because  the  Purchased  Assets  are  not  material  to  Corning’s 
consolidated financial statements.

There were no material acquisitions completed in 2017 or 2016. See Note 
8 (Goodwill and Other Intangible Assets) to the Consolidated Financial 
Statements  for  further  information  on  goodwill  and  intangibles 
acquired in 2017 and 2016.

Amortized  intangible  assets  are  primarily  related  to  the  Optical 
Communications and Life Sciences segments. The net carrying amount 
of  intangible  assets  increased  by  $423  million  during  the  year  ended 
December 31, 2018, primarily due to the acquisition of CMD of $525 million 
and other acquisition of $9 million of other intangible assets, offset by 
amortization of $94 million and foreign currency translation and other 
adjustments of $17 million.

Amortization expense related to all intangible assets is estimated to be 
$115 million annually for 2019, $114 million annually for 2020, $113 million 
annually for 2021, $111 million annually for 2022, and $110 million annually 
for 2023.

South Korean tax deposits
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.

Debt Issuances and Retirements

2017

2018

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

issued  three 

Japanese 

In  the  second  quarter  of  2018,  Corning 
yen-denominated debt securities (the “Notes”), as follows:

issued  three  Japanese 

• ¥21 billion 0.698% senior unsecured notes with a maturity of 7 years;

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

• ¥10 billion 0.722% senior unsecured notes with a maturity of 7 years;

10 years; and

• ¥30.5  billion  1.043%  senior  unsecured  notes  with  a  maturity  of 

• ¥10 billion 1.583% senior unsecured 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. The net proceeds of $700 million 
were made available for general corporate purposes.

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.

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 Income (Loss). 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.

10 years; and

• ¥25 billion 1.219% senior unsecured notes with a maturity of 12 years.

The proceeds from the 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,  were  $596  million.  Payments 
of principle 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. The net proceeds of $596 million will be used for 
general corporate purposes.

In the fourth quarter of 2018, Corning issued three unsecured long-term 
notes as follows:

• $50 million 4.70% senior unsecured notes with a maturity of 19 years;

• $550  million  5.35%  senior  unsecured  notes  with  a  maturity  of 

30 years; and

• $300 million 5.85% senior unsecured notes with a maturity of 50 years.

The  net  proceeds  of  $889  million  will  be  used  for  general  corporate 
purposes.  We  can  redeem  these  notes  at  any  time,  subject  to  certain 
terms and conditions.

In the fourth quarter of 2018, Corning redeemed $250 million of 6.625% 
Notes  due  2019,  paying  a  nominal  call  premium. The  bond  redemption 
incurred an insignificant loss during the fourth quarter of 2018.

11.  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  2018,  we 
made  voluntary  cash  contributions  to  our  domestic  defined  benefit 
pension  plan  and  our  international  pension  plans  in  the  amount  of 
$105 million and $12 million, respectively. In 2017, we made no voluntary 
cash  contributions  to  our  domestic  defined  benefit  pension  plan  and 
$29 million to our international pension plans. During 2019, we anticipate 
making  cash  contributions  of  $75  million  to  our  U.S.  qualified  pension 
plan and $31 million to our international pension plans.

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.

Current year actuarial (gain) loss

Amortization of actuarial net gain

Current year prior service credit

Amortization of prior service credit

Total recognized in other comprehensive income (loss)

Total recognized in net periodic benefit cost and other comprehensive income

The Company expects to recognize $7 million of net prior service cost as 
a component of net periodic pension cost in 2019 for its defined benefit 
pension  plans.  The  Company  expects  to  recognize  $1  million  of  net 
actuarial gain and $7 million of net prior service credit as components of 
net periodic postretirement benefit cost in 2019.

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.

Notes to Consolidated Financial Statements

Corning  last  updated  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,  Corning 
also  updated  to  the  MP-2017  projection  scale  for  the  year  ended  2017. 
As the Society of Actuaries publishes additional mortality improvement 
scales  (MP-2018),  Corning  has  considered  these  revised  improvement 
scales  in  setting  its  future  mortality  improvement  assumption.  As  of 
December 31, 2018, Corning decided to continue application of its future 
improvement scale to the MP-2017 scale.

Furthermore,  Corning  updated  for  the  year  ended  2017  the  mortality 
assumption applied to disabled participants to be the RP-2014 disabled 
mortality  base  table  with  future  improvements  using  MP-2017.  These 
assumptions were unchanged for the year ended 2018.

Plan Assets

The  Company’s  primary  objective  is  to  ensure  the  plan  has  sufficient 
return  on  assets  to  fund  the  plan’s  current  and  future  obligations 
as  they  become  due.  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

59%  of  domestic  plan  assets  are  invested  in  long  duration  bonds. The 
average  rating  for  these  bonds  is  A. These  bonds  are  subject  to  credit 
risk, such that a decline in credit ratings for the underlying companies, 
countries or assets (for asset-backed securities) would result in a decline 
in the value of the bonds. These bonds are also subject to default risk.

Currency Risk

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

Cash Flow Data

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, 2018 and 2017, the amount of Corning common stock 
included in equity securities was not significant.

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.

Product  warranty  liability  accruals  at  December  31,  2018  and  2017 
were 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, 
2018, 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 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 - 2018 Annual Report

Notes to Consolidated Financial Statements

Asbestos Claims
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,  2016,  the  Company’s  liability  under  the  Plan  was 
$290  million,  which  is  required  to  be  paid  through  a  series  of  fixed 
payments  beginning  in  the  second  quarter  of  2017.  Payments  of 
$35  million  and  $70  million  were  made  in  June  2018  and  June  2017, 
respectively.  At  December  31,  2018,  the  total  amount  of  payments  due 
in years 2019 through 2022 is $185 million, of which $50 million is due 
in the second quarter of 2019 and is classified as a current liability. The 
remaining $135 million is classified as a non-current liability.

Non-PCC Asbestos Claims
Corning is a defendant in certain cases alleging injuries from asbestos 
unrelated  to  PCC  (the  “non-PCC  asbestos  claims”)  which  had  been 
stayed  pending  the  confirmation  of  the  Plan.  The  stay  was  lifted  on 
August  25,  2016.  At  December  31,  2018  and  December  31,  2017,  the 
amount of the reserve for these non-PCC asbestos claims was estimated 
to be $146 million and $147 million, respectively. The reserve balance as 
of December 31, 2018 represents the undiscounted projection of claims 
and related legal fees for the estimated life of the litigation.

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  (HSG)  and  formed  a  new  entity  which  had  been  capitalized  by 
Dow  Corning  with  $4.8  billion.  Following  the  realignment,  Corning  no 
longer  owned  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 

13.  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.

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 funded 
a Settlement Trust and a Litigation Facility, referred to above, 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 to 50% of the excess 
liability. At December 31, 2018, Dow Corning had recorded a reserve for 
breast implant litigation of $263 million.

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  compounded  interest  at  default  and 
state  statutory  judgment  rates  as  well  as  attorneys’  fees  and  other 
enforcement costs, during the period from May 1995 through June 2004. 
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 to 50% of the excess liability, subject to certain conditions 
and limits. At December 31, 2018, Dow Corning estimated the liability to 
commercial creditors to be $82 million.

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,  2018  and 
December  31,  2017,  Corning  had  accrued  approximately  $30  million 
(undiscounted)  and  $38  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.

Our most significant foreign currency exposures relate to the Japanese 
yen,  South  Korean  won,  New  Taiwan  dollar,  Chinese  yuan,  the  euro 
and  British  pound.  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 hedge expirations coincide with the timing 
of the underlying foreign currency commitments and transactions.

70 CORNING INCORPORATED - 2018 Annual Report

Notes to Consolidated Financial Statements

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 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.

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 is in other expense, net, relative to 
ineffectiveness, and is not material for the year ended December 31, 2018.

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

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 customers and purchases from suppliers. Our cash flow 
hedging activity also uses interest rate derivatives including Treasury rate 
lock agreements  to reduce  the risk of increases in benchmark interest 
rates on the probable issuance of debt. In the second quarter of 2018, the 
Company entered into Treasury rate lock agreements to hedge against 
the variability in cash flows due to changes in the benchmark interest 
rate  related  to  an  anticipated  debt  issuance.  The  instruments  were 
designated  as  cash  flow  hedges,  and  were  settled  on  October  31,  2018 
concurrent with the debt issuance. The settlement amount of $16 million 
received  will  be  released  from  other  comprehensive  income  into 
earnings when the corresponding interest expense occurs each period.

Corning  uses  a  regression  analysis  to  monitor  the  effectiveness  of 
its  cash  flow  hedges  both  prospectively  and  retrospectively.  Through 
December  31,  2018,  the  hedge 
ineffectiveness  related  to  these 
instruments  was  not  material.  Corning  defers  net  gains  and  losses 
related  to  the  effective  portion  of  cash  flow  hedges  into  accumulated 
other  comprehensive  loss  on  the  consolidated  balance  sheet  until 
the hedged item impacts earnings. At December 31, 2018,  the amount 
expected to be reclassified into earnings within the next 12 months is a 
pre-tax net gain of $2 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. 
In  the  fourth  quarter  of  2018,  Corning  unwound  the  two  interest  rate 
swaps  and  discontinued  the  fair  value  hedge  relationship  accordingly. 
The net losses recorded in current period earnings were not material in 
the Consolidated Statements of Income (Loss).

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.

The  Company  continued  its  foreign  exchange  hedge  program  in  2018 
and entered into a series of average rate forwards, and purchased put 
or call options. These will hedge a significant portion of its projected yen 
exposure for the period of 2019-2022. As of December 31, 2018, the U.S. 
dollar gross notional value of the yen average rate forwards program is 
$9.1  billion  and  $2.6  billion  for  zero-cost  collars  and  purchased  put  or 
call  options. The  average  rate  forward  program  was  also  expanded  to 
partially hedge the impact of the South Korean won, Chinese yuan, euro 
and British pound translation on the Company’s projected net income. As 
of December 31, 2018, these average rate forwards have a total notional 
value of $2.0 billion. The entire average rate forward program will settle 
net  without  obligation  to  deliver  Japanese  yen,  Korean  won,  Chinese 
yuan, euro and British pound. With respect to the zero-cost collars, the 
gross notional amount includes the value of both put and call options. 
However, due to the nature of the zero-cost collars, only the put or the 
call option can be exercised at maturity.

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

14.  Fair Value Measurements

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

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

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

Notes to Consolidated Financial Statements

As  a  result  of  the  acquisition  of  Samsung  Corning  Precision  Materials 
in  January  2014,  the  Company  had  contingent  consideration  that  was 
measured  using  unobservable  (Level  3)  inputs  in  an  option  pricing 
model. The fair value of the contingent consideration was calculated to 
be $300 million as of December 31, 2017. This amount was settled in cash 
and received in June 2018.

15.  Shareholders’ Equity

There were no significant financial assets and liabilities measured on a 
nonrecurring basis during the years ended December 31, 2018 and 2017.

Common Stock Dividends
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  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  paid  in  the  first  quarter 
of 2018. 

On  February  6,  2019,  Corning’s  Board  of  Directors  declared  an  11.1% 
increase  in  the  Company’s  quarterly  common  stock  dividend,  which 
increased  the  quarterly  dividend  from  $0.18  to  $0.20  per  share  of 
common  stock,  beginning  with  the  dividend  paid  in  the  first  quarter 
of  2019.  This  increase  marks  the  eighth  dividend  increase  since 
October 2011.

Fixed Rate Cumulative Convertible Preferred 
Stock, Series A 
On  January  15,  2014,  Corning  designated  a  new  series  of  its  preferred 
stock  as  Fixed  Rate  Cumulative  Convertible  Preferred  Stock,  Series  A, 
par  value  $100  per  share,  and  issued  1,900  shares  of  preferred  stock 
at  an  issue  price  of  $1  million  per  share,  for  an  aggregate  issue  price 
of  $1.9  billion,  to  Samsung  Display  with  the  acquisition  of  its  equity 
interest 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, 2018, 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 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  right  becomes  exercisable  before  the  seventh 
anniversary of  the closing,  the Company must first obtain  the written 
approval  of  the  holders  of  a  majority  of  the  preferred  stock  before 
exercising  its  conversion  right. The  preferred  stock  does  not  have  any 
voting rights except as may be required by law.

Share Repurchases 

2016 Share Repurchases 

In  July  2016,  Corning  entered  into  an  accelerated  share  repurchase 
agreement  (the  “2016  ASR  agreement”)  under  the  2015  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  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.

74 CORNING INCORPORATED - 2018 Annual Report

2017 Share Repurchases 

2018 Share Repurchases 

Notes to Consolidated Financial Statements

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  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.

On  April  26,  2018,  Corning’s  Board  of  Directors  approved  a  $2  billion 
share  repurchase  program  with  no  expiration  (the  “2018  Repurchase 
Program”).  During  the  year  ended  December  31,  2018,  the  Company 
repurchased  74.8  million  shares  of  common  stock  on  the  open  market 
for approximately $2.2 billion, respectively, as part of its 2016 and 2018 
Repurchase Programs.

16.  Earnings (Loss) Per Common Share

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

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

17.  Reportable Segments

Our reportable segments are as follows:

• Display  Technologies  –  manufactures  glass  substrates  for  flat  panel 

liquid crystal displays and other high performance display panels.

• Optical  Communications  –  manufactures  carrier  network  and 
enterprise network components for the telecommunications industry.

• 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.

• Environmental Technologies  –  manufactures  ceramic  substrates  and 

filters for automotive and diesel applications. 

• Life  Sciences  –  manufactures  glass  and  plastic 

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

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

Effective  beginning  in  the  first  quarter  of  2018,  the  Company  has 
changed its measurement of segment sales and segment net income, 
and has recast prior periods presented based on the new methodology. 
Included in this new measurement is a change in our segment tax rate 
to 21% to better reflect the new corporate tax rate under the 2017 Tax 

Act.  Additionally,  the  impact  of  changes  in  the  Japanese  yen,  Korean 
won,  Chinese  yuan  and  New  Taiwan  dollar  will  be  excluded  from 
segment  sales  and  segment  net  income  for  the  Display Technologies 
and  Specialty  Materials  segments,  and  certain  income  and  expenses 
that  were  previously  allocated  to  our  segments  are  now  included  in 
the  unallocated  amounts  in  the  reconciliation  of  reportable  segment 
net  income  to  consolidated  net  income.  These  include  items  that 
are  not  used  by  our  chief  operating  decision  maker  (“CODM”)  in 
evaluating  the  results  of  or  in  allocating  resources  to  our  segments 
and include the following items: the impact of our translated earnings 
contracts;  acquisition-related  costs;  discrete  tax  items  and  other  tax-
related  adjustments;  litigation,  regulatory  and  other  legal  matters; 
restructuring, impairment and other charges; adjustments relating to 
acquisitions; and other non-recurring non-operational items. Although 
we exclude these amounts from segment results, they are included in 
reported consolidated results.

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

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

a segment.

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

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

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

companies and cost investments.
