2019 Financial Performance

Before I delve into our strategy, I’d 
like to share Corning’s financial 
results from last year. Our core sales 
were $11.7 billion, up 2% from 2018, 
driven by growth in Environmental 
Technologies, Specialty Materials, 
and Life Sciences. Core earnings per 
share were $1.76. During 2019, we 
set new four-year targets for growth 
and capital allocation, we increased 
our dividend, and we demonstrated 
our ability to generate significant 
operating cash flow even with 
market performance below our 
expectations. Strong capital 
stewardship is a cornerstone of our 
management approach.

Once again, we outperformed our 
underlying markets in each business 
segment. We grew Environmental 
Technologies sales 16% against a 
backdrop of declining car sales. We 
grew Specialty Materials sales 8% 
while smartphone units were down. 
In Life Sciences, we exceeded industry 
growth rates on the strength of new 
bioprocess and advanced cell culture 
products. In Display Technologies, our 
glass volume grew at a mid-single 
digit rate even though TV unit 
sales were down. And, in Optical 
Communications, we outperformed 

the passive optical market, 
which declined. 

We entered 2019 with strong 
momentum following two years 
of solid growth, and that growth 
continued in the first half of the 
year. In the second half, we felt the 
impact of challenging global 
market conditions, particularly 
in Display Technologies and 
Optical Communications.

In Display Technologies, we 
experienced a temporary supply chain 
adjustment. Set makers purchased 
panels more conservatively, which 
drove panel maker utilization 
reductions in the second half. As panel 
makers purchased less glass, our 
volume declined accordingly. 

In Optical Communications, after 
sales increased 13% year over year in 
the first half, they declined 16% in the 
back half. Changes in spending by 
two large customers accounted 
for a significant portion of the 
year-over-year decline.  

We acted quickly to mitigate lower-
than-expected second-half demand in 
both Display Technologies and 
Optical Communications. While 
everyone in the company relentlessly 

executed by making careful program 
choices, controlling spending, and 
increasing operational efficiencies, 
our profitability declined along
with factory utilization due to 
decreased volume.

We expect to return to sales and profit 
growth in the second half barring 
any external disruptions that could 
severely affect our ability to conduct 
normal business operations. In Display, 
we see indicators that the supply 
chain correction has ended, and we 
expect to resume volume growth in 
2020, with the majority reflected in 
the second half. We also plan to start 
production at our next Gen 10.5 plants, 
which will support faster-than-market 
growth as they ramp. In Optical, we 
expect year-over-year growth in the 
second half, driven by projects for 5G, 
fiber-to-the-home, and hyperscale 
data center deployments. As volumes 
in both businesses increase, so will 
our factory utilization, improving the 
profitability of the corporation. 

Framework Execution and Results

The successful completion of our 
four-year Strategy and Capital 
Allocation Framework represented 
a major milestone for the company.

We met or exceeded the strategic goals 
we set in 2015 while returning more than 
$12.5 billion to shareholders during the 
four-year period, including increasing 
dividends per share by 67%. 

We also made significant progress in 
each of our Market-Access Platforms, 
with continued strong progress in the 
final year of the plan despite second-half 
headwinds. In 2019, we made commercial 
and regulatory progress on Corning 
Valor® Glass, a breakthrough glass for 
the life sciences industry. We opened a 
dedicated factory for our burgeoning 
automotive glass business and grew 
our order book significantly. We also 
advanced several compelling 
innovations in Corning® Gorilla® Glass 
and Optical Communications.

Overall, we advanced our strategic 
position in each of our markets and 
continued technology investments 
focused on high-impact inventions: 

 •

In Automotive, accelerating gasoline 
particulate filter (GPF) adoption  
drove more than $250 million in 
2019 sales. We delivered the    
industry’s first AutoGrade™ Gorilla 
Glass for 2D and 3D interiors along  
with our proprietary Corning® 
ColdForm™ Technology. We also 
commercialized these inventions 

 •

 •

across the auto ecosystem with 
industry leaders, including Visteon 
Corporation, LG Electronics, BOE, 
and GAC.  

In Optical Communications, we 
continued to transform the way the 
world connects by enabling 5G and 
hyperscale data center solutions 
with industry leaders – exemplified 
by collaborations with Intel, Verizon, 
CenturyLink, and Altice Portugal. 
We also earned global recognition 
for products such as RocketRibbon™ 
extreme density cable, which 
enables up to 30% faster installation 
in hyperscale data centers.

In Mobile Consumer Electronics, 
we increased Corning content 
on – and in – mobile devices with 
Amplify screen protectors, decorative 
backs, and durable solutions for 
wearables. Gorilla Glass has now 
been used on more than 7 billion 
devices worldwide thanks to the 
expanded adoption of Gorilla Glass 6 
and advanced glass innovations 
for smartphones, wearables, and 
other devices. We extended our 
industry leadership with next-
generation cover glass solutions and 
deepened customer commitments, 
including an additional $250 million 
investment from Apple’s Advanced

Manufacturing Fund to support Corning’s processes, 
equipment, and materials integral to the delivery of 
next-generation consumer devices.

In Life Sciences Vessels, we signed commercial 
agreements with three major pharmaceutical 
companies, building on the announcement that a 
leading pharmaceutical manufacturer received FDA 
approval of Valor Glass for use as a primary package for 
a marketed drug product. We also exceeded $1 billion 
in sales in our Life Sciences segment as adoption of our 
industry-leading bioprocess and advanced cell culture 
products continued, driving our organic growth.

In Display, we created richer entertainment 
experiences through display glass innovation, 
including the launch of Corning® Astra™ Glass, 
which was selected by Chengdu CEC Panda Display 
Technology Co. for use in the growing oxide display 
market. We continued our leadership in Gen 10.5, 
increasing output at our first Gen 10.5 plant to support 
the market shift to large-size TVs.

Our businesses in each of these markets have the 
potential to contribute to double-digit earnings growth 
in the coming years, which means we have many horses 
pulling the wagon.

Looking Ahead: Strategy & Growth Framework 

As I noted earlier, Corning has successfully managed across 
multiple business cycles during our 169-year history, and 
this cycle will be no different. We expect 2020 to be, in 
many ways, the mirror image of 2019 – with challenging 
market and customer dynamics in the first half and an 
expected return to growth in the second half as both 
Display Technologies and Optical Communications 
improve and strong growth continues in Environmental 
Technologies, Specialty Materials, and Life Sciences. As this 
happens, we expect the company to return to growing sales 
and profitability.

Looking to the longer term, we expect to drive significant 
organic growth and create additional value for shareholders 
under our new Strategy & Growth Framework. Specifically, 
from 2020 to 2023, we expect to deliver 6% to 8% 
compound annual sales growth and 12% to 15% compound 
annual earnings growth. We also expect to expand 
operating margin and return on invested capital. We’ll 
continue to use our cash to grow, extend our leadership, 

and reward shareholders. We plan to invest between $10 
billion and $12 billion with a focus on organic growth. And 
we intend to return $8 billion to $10 billion to shareholders 
through a combination of dividend increases and 
opportunistic share repurchases.

Under our new Framework, from 2020 to 2023, we seek to 
increase annual sales by $3 billion to $4 billion and improve 
profitability, driven primarily by our strategy to create – 
and sell into – new product categories that enhance our 
customers’ offerings. That provides a path to growth – 
even in challenging markets. We’re not just counting on 
everybody buying more stuff; we’re putting more Corning 
into the products people already buy.

Our technology and commercial progress reinforce our 
position for growth and market momentum. We are excited 
by the breadth and depth of the opportunities we have 
created in each of our markets. Here is a closer look at the 
Market-Access Platform opportunities that support our 
four-year 6% to 8% sales growth CAGR target:

 •

 •

In Automotive, we remain on track to double sales 
by the end of 2023. In emissions control, regulations 
continue to increase our opportunity per car, and our 
GPF technology positions us as the industry leader. 
In auto glass, designers increasingly rely on interior 
glass as a point of differentiation. Our proprietary 
technology uniquely meets their needs. We also see 
upside in glass components for head-up displays and 
autonomous vehicles. Successfully ramping our new 
Hefei factories is key to our success. 

In Optical Communications, our technologies will 
play a key role in both 5G and hyperscale data center 
deployments. Our new suite of products for 5G and 
preconnectorized solutions for data centers will play 
a vital role in the acceleration of these key industry 
trends. We are also making adjustments to how we 
run the business, with operational improvements 
in product development and delivery, inventory 
management, and overall accountability. We will 
continue to align production output and working 
capital to current customer demand. That type of focus 
and improvement takes hard work, but I’m encouraged 
by the team’s dedication and progress. 

 •

In Mobile Consumer Electronics, our sales continue on 
a path to doubling, driven by Gorilla Glass performance 
innovations that push the state-of-the-art forward. 
Acceptance of our DX and DX+ durable covers for 

smartwatches is outstanding, and innovations for 
foldables are making progress. We believe that 5G 
could stimulate smartphone unit growth and also 
increase the number of phones with our glass on the 
front and the back.

In Life Sciences Vessels, our leadership continues to 
drive growth at more than twice the industry rate. We 
are leaders in products for cell-based medicine, which 
is one of the most promising and fastest growing life 
sciences segments. Additionally, Valor Glass provides a 
new standard for drug packaging. 

In Display, we expect to see further stabilization 
as panel maker utilization increases, TV screen size 
continues to increase, and our new Gen 10.5 plants 
come online.

 •

 •

For investors, it’s important to note that the majority of 
capital necessary to deliver on our Strategy & Growth 
Framework goals has already been deployed. And our 
technology and commercial progress position us to capture 
the significant opportunities we see.

Closing Thoughts

Our sustained investments in technology and people, 
and our ability to create some of the most consequential 
material innovations in history, are what make Corning 
a leader in the markets we serve. It’s why our cover glass 
has been featured on more than 7 billion mobile devices 
worldwide since the launch of Gorilla Glass. It’s why we’ve 
steadily increased our competitive advantage in display 

glass over the last 35 years. It’s how we’re extending 50 
years of automotive leadership to keep winning in the 
newest category of emissions control. It’s also why top 
pharmaceutical and biotech companies are turning 
to Corning for their production and protection needs. 
And it’s why we’re able to utilize 50 years of Optical 
Communications expertise to transform the way the world 
connects. Today, few competitors can match our expertise 
in any of our core capabilities, and when we combine 
capabilities, we become truly formidable.

We have not only maintained our competitive advantage 
over decades—we’ve increased it. And we will continue 
to do so during the next four years. We have never 
been satisfied with what is currently possible. We have 
never been attracted to what is easiest. We have never 
substituted short-term returns for long-term value, which 
gives us the focus and intensity to persevere through 
challenging times. 

We are all deeply committed to the success of this 
institution and to working every day to maintain the trust 
of shareholders. We are grateful for your partnership on 
our journey to bring life-changing innovations and products 
to the world.

Sincerely,

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

connectivity  solutions  for  state-of-the-art  communications  networks; 
trusted products to accelerate drug discovery and delivery; and clean-air 
technologies for cars and trucks.

Corning  operates  in  five  reportable  segments:  Display  Technologies, 
Optical  Communications,  Environmental  Technologies,  Specialty 
Materials and Life Sciences, and manufactures products at 116 plants in 
15 countries.

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

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

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

• Corning  IRIS™  Glass,  a  light-guide  plate  solution  which  enables 

televisions and monitors to be less the 5-mm thick; 

• The family of Corning LOTUS™ Glass, high-performance display glass 
developed  to  enable  cutting-edge  technologies,  OLEDs  and  next 
generation  LCDs.  These  substrate  glasses  provide  industry-leading 
levels of low  total pitch variation, resulting in brighter, more energy-
efficient  displays  with  higher  resolutions  for  consumers  and  better 
yields for panel makers; 

• The  world’s  first  Gen  10  and  Gen  10.5  glass  substrates  in  support  of

CORNING 2019 ANNUAL REPORTBusiness Description

In  prior  years,  HSG’s  solar  and  semiconductor  customers  entered  into 
long-term “take or pay” contracts which included up-front cash payments 
to  secure  capacity.  During  the  last  few  years,  and  more  significantly 
in  2019,  the  solar  power  panel  industry  experienced  significant  over-
capacity in the market, resulting in declining sales volumes and market 
prices.  As  a  result,  HSG’s  solar  business  experienced  lower  market 
penetration, overall price declines, and settled contracts with customers 
that had committed volume and fixed pricing above the current market 
price. While  these  settlements  positively  impacted  HSG’s  cash  flow  in 
2019, they reduced expectations for future sales in HSG’s solar business.

Due  to  the  adverse  change  in  HSG’s  solar  business,  HSG  was  required 
to assess the recoverability of its long-lived assets in the fourth quarter. 
Based  on  this  assessment,  HSG  determined  that  the  carrying  values 
of  HSG’s  solar  asset  group  significantly  exceeded  its  fair  values.  HSG 
engaged a third-party appraiser to assist in determining the fair value 
of the assets within in the solar asset group based on the highest and 
best use of the asset group. As a result of the fair value determination, 
HSG  recognized  a  pre-tax  asset  impairment  charge  of  $916  million 
for  the  year  ended  December  31,  2019.  Corning’s  share  of  the  pre-tax 
impairment was $369 million. 

Competition

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

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

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

Due  to  the  adverse  changes  above,  the  carrying  values  of  HSG’s  solar 
business inventories were also affected resulting in an inventory write-
down of $257 million for the year. Corning’s pre-tax share of the provision 
was $105 million. 

HSG  adopted  the  new  revenue  standard  on  January  1,  2019  and  the 
timing of HSG’s revenue recognition for certain remaining performance 
obligations  measured  at  January  1,  2019  was  deferred  for  recognition. 
This  deferral  reduced  the  carrying  amount  of  Corning’s  investment  in 
HSG  by  $239  million.  During  the  fourth  quarter,  a  significant  number 
of  the  performance  obligations  were  satisfied  and  $434  million  was 
recognized into HSG’s net income. Corning’s share of the equity earnings 
was $208 million.

In addition, HSG settled certain revenue contracts in the fourth quarter, 
resulting  in  settlement  gains  of  $383  million  in  net  income.  Corning’s 
share of the settlement gains was $185 million. 

Additional  information  about  corporate  investments  is  presented  in 
Note 6 (Investments) to the consolidated financial statements.

CORNING 2019 ANNUAL REPORTRaw Materials

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

Patents and Trademarks

Inventions  by  members  of  Corning’s  research  and  engineering  staff

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  &  Growth  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.

CORNING 2019 ANNUAL REPORTRisk Factors

Compliance  with  laws  and  regulations  increases  our  costs.  We  are 
subject  to  both  U.S.  laws  and  the  local  laws  where  we  operate  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. 

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

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

among countries;

• 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;

• Complex, changing or competing tax regimes; 

• Difficulty in collecting obligations owed to us;

• Natural  disasters  such  as  floods,  earthquakes,  tsunamis  and 

windstorms; and

• Potential loss of utilities or other disruption affecting manufacturing.

Corning’s Display Technologies segment generates a significant amount 
of  the  Company’s  profits  and  cash  flow.  Any  significant  decrease  in 
display glass pricing or market share 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 ongoing pricing pressure 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:

Business disruptions could affect our operating results 

A major earthquake, weather event, fire or other catastrophic event that 
results  in  the  destruction  or  disruption  of  any  of  our  critical  facilities, 
or our suppliers’ or customers’ facilities, could severely affect our ability 
to  conduct  normal  business  operations  and,  as  a  result,  our  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. 

We have been closely monitoring the outbreak of the coronavirus that 
originated  in Wuhan,  China. We  have  operations  in Wuhan  and  other 
areas  of  China.  We  have  taken  steps  to  protect  our  employees  and 
operations. The coronavirus may impact the global economy, our ability, 
as  well  as  the  ability  of  our  customers  and  suppliers,  to  manufacture 
products  and  may  reduce  demand  in  our  markets  which  could  result 
in  an  impact  to  our  financial  results. We  are  taking  steps  to  mitigate 
potential  financial  impacts,  including  supplying  customers  from  other 
regions when appropriate. Currently, it is not possible for us to determine 
the financial impact of the coronavirus, if any.

CORNING 2019 ANNUAL REPORT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  and  social  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.

Given  the  geographical  concentration  of  certain  of  our  plants,  the 
highly  engineered  nature  of  our  facilities  and  the  globally  dispersed 
talent required to run these facilities, any event that adversely affects or 
restricts movement into or out of a specific geographic area where we, 
our suppliers, or our customers have a presence, could adversely impact 
our results.

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  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. 

Risk Factors

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

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.  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.  Any  significant  disruption,  breakdown,  intrusion, 
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.  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  U.S.  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 increases or decreases significantly 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 sell in various currencies.

These  factors,  which  are  variable  and  generally  outside  of  our  control, 
could  materially  impact  our  results  of  operations,  anticipated  future 
results, financial position and cash flows.

CORNING 2019 ANNUAL REPORTRisk Factors

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.

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. 
There  are  many  transactions  and  calculations  where  the  ultimate  tax 
treatment 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.  Significant  guidance  has  been  issued  with  the  intention  of 
clarifying the new tax provisions. To date, some of the regulations had 
been finalized and clarified but a considerable amount of this guidance 
is still in the form of proposed regulations. Due to volume and complexity 
of both of final and proposed regulations, we continue to evaluate any 
development and impact of the 2017 Tax Act that could have a material 
adverse impact on our tax expense and cash flow. In addition to the 2017 
Tax  Act,  other  foreign  countries  and  international  organizations  such 
as Organisation for Economic Co-operation and Development (“OECD”) 
may have law changes and issue new international tax standards that 
may also impact our taxes.

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

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

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

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

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

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

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. Any such substantial legal 
liability or regulatory action 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.

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

CORNING 2019 ANNUAL REPORTLegal Proceedings

Moreover,  several  of  our  key  customers  are  domiciled  in  areas  of  the 
world  with  laws,  rules  and  business  practices  that  may  notably  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 13 (Commitments, Contingencies and 
Guarantees)  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,  2019  and  2018,  Corning  had 
accrued  approximately  $41  million  (undiscounted)  and  $30  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.

CORNING 2019 ANNUAL REPORTManagement’s Discussion and Analysis of Financial 
Condition and Results of Operations

For discussion of 2018 results year-over-year comparison with 2017 results refer to "Management's Discussion and Analysis of Financial Conditions and 
Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

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 

Strategy and Capital Allocation Framework 
and recently introduced Strategy & 
Growth Framework
On  June  14, 2019,  Corning  introduced  its  2020-2023  Strategy  &  Growth 
Framework. From 2020 to 2023, the company plans to invest $10 billion to 
$12 billion for growth and to return $8 billion to $10 billion to shareholders.

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  outlined  our  leadership  priorities 
and  articulated  the  opportunities  we  saw  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  targeted  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.  As  of  June  30,  2019,  Corning  met  its  goal  of  returning  more 
than $12.5 billion to shareholders. As of December 31, 2019, Corning had 
invested almost $11 billion for growth and extended leadership.

Corning’s Frameworks outline the company’s leadership priorities. With 
the  completed  Strategy  and  Capital  Allocation  Framework  and  new 
Strategy  &  Growth  Framework,  Corning  plans  to  focus  its  portfolio 
and  utilize  its  financial  strength.  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 along with capital spending on a cohesive set of three core 
technologies,  four  manufacturing  and  engineering  platforms,  and  five 
market-access  platforms.  This  strategy  allows  us  to  quickly  apply  our 
talents  and  repurpose  our  assets  across  the  company,  as  needed,  to 
capture high-return opportunities. 

2019 Results
Net sales in the year ended December 31, 2019 were $11.5 billion, an increase 
of $213 million, or 2%, when compared to the year ended December 31, 
2018, driven by increased sales in the Specialty Materials, Environmental 
Technologies and Life Sciences segments offset by decreased sales in the 
Display Technologies and Optical Communications segments.

• Environment

• Critical Accounting Estimates

• New Accounting Standards

• Forward-Looking Statements

For  the  year  ended  December  31,  2019,  we  generated  net  income 
of  $960  million,  or  $1.07  per  share,  compared  to  a  net  income  of 
$1,066 million, or $1.13 per share, for 2018. When compared to 2018, the 
$106 million decrease in net income was primarily due to the following 
items (amounts presented after tax): 

• Lower  equity  earnings  in  affiliated  companies  of  $284  million  when 
compared  to  the  prior  period,  primarily  driven  by  asset  impairments 
and  an  inventory  provision,  partially  offset  by  the  deferred  revenue 
recognition associated with adoption of the new revenue standard, as 
well as one-time settlement gains from revenue contracts;

• Higher  costs  of  $238  million,  primarily  driven  by  accelerated 
depreciation  and  asset  write-offs  for  our  Display  Technologies  and 
Optical Communications segments; and

• Lower segment net income of $83 million primarily driven by lower sales 
in our Display Technologies and Optical Communications segments.

Partially offsetting these events were the following items:

• Translated  earnings  contract  gains  in  the  current  period  were 

$287 million higher than prior year losses;

• Costs  related  to  litigation,  regulatory  and  other  legal  matters  were 
$109  million  lower,  primarily  driven  by  the  absence  of  a  $103  million 
charge related to legal matters recorded in 2018, including a ruling in 
an intellectual property lawsuit and developments in civil litigation;

• A positive impact of $44 million resulting from a lower mark-to-market 

loss for our defined benefit pension plans; and 

• The positive impact of $42 million in tax adjustments primarily relating 
to the absence of a $172 million IRS audit settlement, or approximately 
$40  million  of  taxes  payable  after  the  utilization  of  tax  attributes, 
recorded  in  the  first  quarter  of  2018,  netted  against  changes  in  tax 
reserves, changes in foreign valuation allowances and changes in the 
estimate of 2018 tax expense due to new tax reform guidance.

CORNING 2019 ANNUAL REPORTManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Diluted  earnings  per  share  decreased  by  $0.06  per  share,  or  5%,  when 
compared to 2018, driven by the decrease in net income described above, 
partially offset by the repurchase of 31.0 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  the  current  year, 
negatively impacted Corning’s net income by approximately $44 million 
in the year ended December 31, 2019, when compared to the same period 
in 2018.

2020 Corporate Outlook
We  have  been  closely  monitoring  the  outbreak  of  the  coronavirus 
that  originated  in  Wuhan,  China.  We  have  operations  in  Wuhan  and 
other  areas  of  China.  We  have  taken  steps  to  protect  our  employees 
and  operations.  The  coronavirus  may  impact  the  global  economy, 
our  ability,  as  well  as  the  ability  of  our  customers  and  suppliers,  to 

manufacture products and may reduce demand in our markets which 
could  result  in  an  impact  to  our  financial  results. We  are  taking  steps 
to mitigate potential financial impacts, including supplying customers 
from other regions when appropriate. Currently, it is not possible for us 
to  determine  the  financial  impact  of  the  coronavirus,  if  any.  Our  2020 
corporate outlook, outlined above, does not include any potential impact 
for the coronavirus. 

We  believe  2020  will  be  another  year  of  growth  in  several  segments 
and continued investment in innovations, consistent with our Strategy 
&  Growth  Framework.  Corning  expects  its  display  glass  volume  to 
grow  by  a  mid-single  digit  percentage,  similar  to  the  mid-single 
digit  percentage  growth  expected  in  the  display  glass  market.  The 
company expects glass price declines to remain moderate, down a mid-
single  digit  percentage  for  the  full  year. The  company  expects  Optical 
Communications full-year sales to decline by 5% to 10%. We expect mid-
single digit percentage sales growth in our Environmental Technologies 
and  Life  Sciences  segments.  We  expect  high-single  digit  percentage 
sales growth in the Specialty Materials segment.

For the year ended December 31, 2019, segment net sales increased by 
$258  million,  or  2%,  when  compared  to  the  same  period  in  2018.  The 
primary sales drivers by segment were as follows:

• Net sales in the Display Technologies segment decreased by $22 million, 
with  glass  volume  up  a  mid-single  digit  percentage  and  low-single 
digit  percentage  display  glass  price  declines;  the  combination  of 
finished  goods  volume,  unfinished  glass  sold  to  our  equity  affiliates 
and  a  low-single-digit  percentage  price  decline  resulted  in  a  one 
percent sales decline; 

• Optical  Communications  net  sales  decreased  $128  million,  primarily 
due  to  lower  sales  in  carrier  products,  down  $199  million,  partially 
offset by an increase of $71 million in enterprise network sales; 

• Specialty  Materials  segment  net  sales  increased  by  $115  million, 

primarily driven by strong demand for Gorilla® Glass; 

• Net  sales  for  Environmental  Technologies  increased  $210  million, 

primarily driven by sales growth of gasoline particulate filters; and

• Life  Sciences  net  sales  increased  by  $69  million,  as  sales  volume 

continued to outpace market growth.

Movements  in  foreign  exchange  rates  negatively  impacted  Corning’s 
consolidated  net  sales  by  $45  million  in  the  year  ended  December  31, 
2019, when compared to the same period in 2018.

In  2019,  sales  in  international  markets  accounted  for  68%  of  total 
net sales. 

Gross Margin
In  the  year  ended  December  31,  2019,  gross  margin  dollars  decreased 
by  $426  million,  or  10%,  and  gross  margin  as  a  percentage  of  net 
sales  declined  by  5%  when  compared  to  the  same  period  last  year. 
Negative impacts to gross margin were primarily driven by accelerated 
depreciation, asset write-offs and lower sales in our Display Technologies 
and Optical Communications segments during 2019. As volume declined 
in  the  second  half  of  2019,  factory  utilization  was  less  efficient  and 

negatively impacted gross margin. 

Movements in foreign exchange rates had a $33 million positive impact 
on Corning’s consolidated gross margin in the year ended December 31, 
2019, when compared to the same period in 2018.

Selling, General and Administrative Expenses 
When compared  to  the year ended December 31, 2018, selling, general 
and  administrative  expenses  decreased  by  $214  million,  or  12%,  in  the 
year  ended  December  31,  2019.  Selling,  general  and  administrative 
expenses  decreased  by  2%  as  a  percentage  of  sales. The  decrease  was 
primarily driven by the following items: 

• The absence of a $132 million charge related to legal matters in 2018, 
including a ruling in an intellectual property lawsuit and developments 
in civil litigation matters; and

• Reduced variable compensation expenses of $85 million. 

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.

Research, Development and Engineering  
Expenses 
For  the  year  ended  December  31,  2019,  research,  development  and 
engineering expenses increased by $38 million, or 4%, when compared 
to the same period in prior year, driven by higher costs associated with 
new  product  launches  and  our  emerging  businesses.  As  a  percentage 
of sales,  these expenses were consistent when compared  to  the same 
period in the previous year.

CORNING 2019 ANNUAL REPORTManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Equity in Earnings of Affiliated Companies
The following provides a summary of equity earnings (losses) of affiliated companies (in millions):

Hemlock Semiconductor Group

All other

Total equity earnings

In  2016,  Corning  realigned  its  ownership  interest  in  Dow  Corning, 
exchanging  its  50%  interest  in  the  joint  venture  between  Corning 
and  Dow  Chemical  for  a  newly  formed  company  that  holds  a  49.9% 
interest  in  Hemlock  Semiconductor  LLC  and  a  40.25%  interest  in 
Hemlock  Semiconductor  Operations  LLC  which  are  recorded  as  equity 
method  investments  of  Corning  and  are  affiliated  companies  of  HSG. 
HSG  manufactures  polysilicon  products  for  the  semiconductor  and 
solar  industries.  HSG’s  solar  business  primarily  serves  the  solar  power 
panel industry. 

In  prior  years,  HSG’s  solar  and  semiconductor  customers  entered  into 
long-term “take or pay” contracts which included up-front cash payments 
to  secure  capacity.  During  the  last  few  years,  and  more  significantly 
in  2019,  the  solar  power  panel  industry  experienced  significant  over-
capacity in the market, resulting in declining sales volumes and market 
prices.  As  a  result,  HSG’s  solar  business  experienced  lower  market 
penetration, overall price declines, and settled contracts with customers 
that had committed volume and fixed pricing above the current market 
price. While  these  settlements  positively  impacted  HSG’s  cash  flow  in 
2019, they reduced expectations for future sales in HSG’s solar business.

Due  to  the  adverse  change  in  HSG’s  solar  business,  HSG  was  required 
to assess the recoverability of its long-lived assets in the fourth quarter. 
Based  on  this  assessment,  HSG  determined  that  the  carrying  values 
of  HSG’s  solar  asset  group  significantly  exceeded  its  fair  values.  HSG 
engaged a third-party appraiser to assist in determining the fair value 
of the assets within in the solar asset group based on the highest and 
best use of the asset group. As a result of the fair value determination, 
HSG  recognized  a  pre-tax  asset  impairment  charge  of  $916  million 
for  the  year  ended  December  31,  2019.  Corning’s  share  of  the  pre-tax 
impairment was $369 million.

Due  to  the  adverse  changes  above,  the  carrying  values  of  HSG’s  solar 
business inventories were also affected resulting in an inventory write-
down of $257 million for the year. Corning’s pre-tax share of the provision 
was $105 million. 

HSG  adopted  the  new  revenue  standard  on  January  1,  2019  and  the 
timing of HSG’s revenue recognition for certain remaining performance 
obligations  measured  at  January  1,  2019  was  deferred  for  recognition. 
This  deferral  reduced  the  carrying  amount  of  Corning’s  investment  in 
HSG  by  $239  million.  During  the  fourth  quarter,  a  significant  number 
of  the  performance  obligations  were  satisfied  and  $434  million  was 
recognized into HSG’s net income. Corning’s share of the equity earnings 
was $208 million.

In addition, HSG settled certain revenue contracts in the fourth quarter, 
resulting  in  settlement  gains  of  $383  million  in  net  income.  Corning’s 
share of the settlement gains was $185 million. 

Additional  information  about  corporate  investments  is  presented  in 
Note 6 (Investments) to the consolidated financial statements.

Translated earnings contracts 
Included  in  the  line  item  translated  earnings  contract  gain  (loss),  net, 
is  the  impact  of  foreign  currency  hedges  which  hedge  our  translation 
exposure  arising  from  movements  in  the  Japanese  yen,  South  Korean 
won,  new Taiwan  dollar,  euro,  Chinese  yuan  and  British  pound  and  its 
impact on our net income (loss).

Income Before Income Taxes
The  translation  impact  of  fluctuations  in  foreign  currency  exchange  rates,  including  the  impact  of  hedges  realized  in  the  current  year,  negatively 
impacted Corning’s income before income taxes by $39 million in the year ended December 31, 2019, when compared to the same period in 2018.

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

130.0%

For  the  year  ended  December  31,  2019,  the  effective  income  tax  rate 
differed from the U.S. statutory rate of 21% primarily due to the following:

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

deferred tax assets that are now considered realizable.

• Additional net provision of $102 million from changes to our tax reserves;

• A  net  benefit  of  $45  million  due  to  releases  of  foreign  valuation 
allowances  on  foreign  deferred  tax  assets  that  are  now  considered 
realizable; and

• Additional net benefit, including a change in estimate from prior year, 
from  the 2017 Tax Act attributable  to foreign intangible income (FDII) 
deduction of $103 million offset by taxes for global intangible low-taxed 
income (GILTI) of $15 million.

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

Generally, 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, (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, and (6) future distribution would trigger a significant federal 
income inclusion to the U.S. shareholder.

During 2019, the Company distributed approximately $424 million from 
foreign  subsidiaries  to  their  respective  U.S.  parent  companies.  As  of 
December 31, 2019, Corning has approximately $2.5 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 5 (Income Taxes) to the consolidated financial statements 
for further details regarding income tax matters.

These losses were partially offset by the following:

For the year ended December 31, 2019, comprehensive income decreased 
by $99 million, when compared to the same period in 2018, primarily due 
to the following:

• A decrease in the loss on foreign currency translation adjustments in 
the amount of $42 million, most significantly impacted by the Chinese 
yuan, South Korean won and Japanese yen; and

• A decrease in net income of $106 million; and

• An  $83  million  increase  in  unamortized  actuarial  losses  for  post-
retirement  benefit  plans,  $53  million  of  which  was  related  to  the 
adoption  of  the  new  standard  for  reclassification  of  stranded  tax 
effects in AOCI with the remainder of the impact driven by decreases 
in the discount rates used to value our post-retirement obligations.

• The impact of a change to net unrealized gains on designated hedges 

of $46 million.

Refer to Note 12 (Employee Retirement Plans) and Note 16 (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  report  core  performance 
measures.  These  items  include  gains  and  losses  on  our  translated 
earnings contracts, acquisition-related costs, certain discrete tax items 
and other tax-related adjustments, restructuring, impairment, and other 
charges or credits, 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. Corning utilizes 
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. Effective January 1, 2019, Corning 
also  began  using  constant-currency  reporting  for  our  Environmental 
Technologies  and  Life  Sciences  segments  for  the  euro,  Japanese  yen 
and  Chinese  yuan.  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.

CORNING 2019 ANNUAL REPORTManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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  foreign  currencies  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.

Effective July 1, 2019, we replaced the term “Core Earnings” with “Core Net 
Income”. The terms are interchangeable and the underlying calculations 
remain the same.

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

Core Net Income

2019 vs. 2018

In the year ended December 31, 2019, we generated core net income of 
$1,578 million or $1.76 per share, compared to core net income generated 
in  the  year  ended  December  31,  2018  of  $1,673  million,  or  $1.78  per 
share. The decrease in core net income of $95 million was driven by the 
following items:

• A  decrease  in  the  Optical  Communications  segment  of  $103  million 

primarily driven by decreases in volume;

• A  decrease  in  the  Display  Technologies  segment  of  $49  million 
primarily  driven  by  decreases  in  volume  and  glass  shipments  during 
the  second  half  of  2019,  resulting  in  lower  factory  utilization  and 
negatively impacting profitability; and

• A  decrease  of  $11  million  in  the  Specialty  Materials  segment,  largely 
driven  by  the  absence  of  customer  support  for  new  product 
development costs for the launch of new product innovations in 2019.

Partially  offsetting  these  decreases 
the following:

• An increase in the Environmental Technologies segment of $55 million 
resulting  from  earnings  growth  driven  by  increased  sales  of  gas 
particulate filters; and

• An increase of $33 million in the Life Sciences segment resulting from 

higher volumes outpacing the underlying market.

Core earnings per share decreased in the year ended December 31, 2019 
to $1.76 per share, driven by the decrease in core net income and partially 
offset by the repurchase of 31.0 million shares of common stock over the 
last twelve months.

Included in core net income for the years ended December 31, 2019, 2018 
and 2017, is net periodic pension expense in the amount of $84 million, 
$52 million and $49 million, which excludes the annual pension mark-to-
market adjustments.

Refer  to  Note  12  (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 consolidated 
statements of income (loss) 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 consolidated statements 
of income (loss) or statement of cash flows.

Core net sales, core equity in earnings of affiliated companies and core net 
income 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.

(1)  Constant-currency adjustment: Because a significant portion of segment revenues and expenses are denominated in currencies other than the 
U.S. dollar, management believes it is important to understand the impact on core net income of translating these currencies into U.S. dollars. 
Our Display Technologies segment sales and net income are primarily denominated in Japanese yen, but also impacted by  the South Korean 
won, Chinese yuan, and new Taiwan dollar. Beginning January 1, 2019, as our Environmental Technologies and Life Science segments sales and 
net income are impacted by the euro, Chinese yuan and Japanese yen, these segments will also be presented on a constant-currency basis. We 
have not recast the prior periods for these two segments as the impact of fluctuations in these currencies are not material for prior periods. 
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. We establish constant-currency rates based on 
internally derived management estimates which are closely aligned with the currencies we have hedged.

Constant-currency rates are as follows:

Currency

Rate

Japanese yen

¥107

Korean won
₩1,175

Chinese yuan

New Taiwan dollar

Euro

¥6.7

NT$31

€.81

(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 2019, these include discrete period tax items such as changes in tax law, the impact 
of  tax  audits,  changes  in  judgement  about  the  realizability  of  certain  deferred  tax  assets  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, 
adjustments to our estimated liability for environmental-related items and other legal matters.

(7)  Restructuring, impairment and other charges or credits: This amount includes restructuring, impairment and other charges or credits, as well as 
other expenses, primarily accelerated depreciation and asset write-offs, which are not related to continuing operations and are not classified as 
restructuring expense.

25

CORNING 2019 ANNUAL REPORT 
Management’s Discussion and Analysis of Financial Condition and Results of Operations

(8)  Equity  in  (earnings)  losses  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  (“CPM”)  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)  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 resulting 
from 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  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,  serum  and  reagents  enabling  workflow  solutions  for  drug 
discovery and bioproduction.

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.

We prepared the financial results for our reportable segments on a basis 
consistent  with  our  internal  disaggregation  of  financial  information  to 
assist in making internal operating decisions.  We use a segment tax rate 
of 21% when presenting segment information.  The impact of changes in 
the Japanese yen, euro, South Korean won, Chinese yuan and new Taiwan 
dollar are excluded from segment sales and segment net income for the 
Display  Technologies,  Specialty  Materials,  Environmental  Technologies 
and Life Science segments.  Certain corporate income and expenses are 
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 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; certain litigation, regulatory 
and other legal matters; restructuring, impairment and other charges or 
credits;  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 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.

2019 vs. 2018
Net sales in the Display Technologies segment decreased by $22 million, 
or 1%, for the year ended December 31, 2019, when compared to the prior 
year.  Corning’s glass volume increased by a mid-single digit percentage, 
higher  than  the  overall  market,  driven  by  increased  Gen  10.5  output 
during the year.  The combination of finished goods volume, unfinished 
glass sold to our equity affiliates and a low-single-digit percentage price 
decline resulted in a one percent sales decline.

Net  income  in  the  Display  Technologies  segment  decreased  by  $49 
million  in  the  year  ended  December  31,  2019,  driven  by  the  decrease  in 
sales outlined above.  Display Technologies shipped more glass in the first 
half  of  2019  than  in  the  latter  half.    Due  to  lower  glass  volumes  in  the 
second half of 2019, factory utilization declined impacting profitability.

Outlook:

For  full-year  2020,  Corning  expects  its  display  glass  volume  to  grow  by 
a mid-single digit percentage, similar to the mid-single digit percentage 
growth  expected  in  the  display  glass  market.    The  company  expects 
display  glass  price  declines  to  remain  moderate,  down  a  mid-single 
percentage for the full year.

Net sales declined by $128 million, or 3%, in  the year ended December 
31,  2019,  when  compared  to  the  same  period  in  2018,  primarily  due  to 
lower sales in carrier products, down $199 million, partially offset by an 
increase  of  $71  million  in  enterprise  network  sales.    Sales  were  lower 
than  expected  due  to  weakness  in  the  optical  market,  highlighted  by 
capital spending reductions at two of our significant customers in the 
latter half of 2019.

Net  income  in  the  year  ended  December  31,  2019  decreased  by  $103 
million, or 17%.  Lower sales volumes in the latter half of 2019 drove less 
efficient factory utilization negatively impacting profitability.

Movements  in  foreign  currency  exchange  rates  did  not  materially 
impact net income in this segment in the year ended December 31, 2019 
when compared to the same period in 2018.

Outlook:

Full-year 2020 Optical Communications sales are expected to decrease 
by five to ten percent on a year-over-year basis.

period in 2019, primarily driven by strong demand for Gorilla® Glass.

Net income in the year ended December 31, 2019 decreased by $11 million, 
or 4%, when compared  to  the same period in 2018.  The decrease was 
primarily related  to  the absence of customer support for new product 
development costs for the launch of new product innovations in 2019.

Outlook:

The  company  expects  high-single  digit  percentage  growth  for  the 
Specialty Materials segment on a year-over-year basis for full-year 2020.

Net  income  in  the  year  ended  December  31,  2019  increased  by  $55 
million, or 26%, driven by the sales increase outlined above and strong 
operational performance and successful ramping of additional gasoline 
particulate filter capacity in China.

Outlook:

We expect mid-single digit sales growth on a year-over-year basis in our 
Environmental Technologies segment for full-year 2020.

Outlook:

For  full-year  2020,  sales  are  expected  to  grow  by  a  mid-single-digit 
percentage on a year-over-year basis.

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

Net sales of this segment increased by $14 million, or 6%, in the year ended December 31, 2019, respectively, when compared to the same period in 2018, 
driven by an increase in sales in our emerging businesses.  The increase in the net loss of $8 million, a decline of 3%, reflects increased spending on our 
development projects when compared to 2018.

Liquidity and Capital Resources

Financing and Capital Structure
The following items discuss Corning’s financing and changes in capital 
structure during 2019 and 2018:

2019

In  the  third  quarter  of  2019,  Corning 
yen-denominated debt securities (the “Notes”), as follows:

issued  two 

Japanese 

• ¥31.3  billion  1.153%  senior  unsecured  notes  with  a  maturity  of 

12 years; and

• ¥5.9 billion 1.513% senior unsecured notes with a maturity of 20 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  approximately  $349 
million  and  will  be  used  for  general  corporate  purposes.    Payments  of 
principal  and  interest  on  the  Notes  will  be  in  Japanese  yen,  or  should 
yen be unavailable due to circumstances beyond Corning’s control, a U.S. 
dollar equivalent.

In the fourth quarter of 2019, Corning issued two U.S. dollar-denominated 
debt securities (the “Notes”), as follows:

• $400  million  3.90%  senior  unsecured  notes  with  a  maturity  of 

30 years; and

• $1.1 billion 5.45% senior unsecured notes with a maturity of 60 years.

The net proceeds, after deducting offering expenses, were approximately 
$1.5  billion  and  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  2019,  Corning  redeemed  $300  million  of 
4.25% notes due in 2020, paying a premium of $4.7 million by exercising 
our make-whole call.  The bond redemption resulted in an $8.4 million 
loss during the same quarter.

Common Stock Dividends
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

stock, beginning with the dividend paid in the first quarter of 2019.

On  February  5,  2020,  Corning’s  Board  of  Directors  declared  an  10.0% 
increase  in  the  Company’s  quarterly  common  stock  dividend,  which 
increased  the  quarterly  dividend  from  $0.20  to  $0.22  per  share  of 
common stock, beginning with the dividend paid in the first quarter of 
2020. This increase marks the ninth dividend increase since October 2011.

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, 2019, the preferred stock has not been converted, and none 
of the anti-dilution provisions have been triggered.

Customer Deposits
As  of  December  31,  2019  and  2018,  Corning  had  customer  deposits 
of  approximately  $1.0  billion.  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. Credit memoranda of $37 million were issued in 2019; 
no such memoranda were issued in 2018.

Capital Spending
Capital  spending  totaled  $1,978  million 
in  2019,  a  decrease  of 
$264  million  when  compared  to  2018,  primarily  driven  by  lower 
spending  in  the  Optical  Communications  and  Display  Technologies 
segments. We expect our 2020 capital expenditures to be approximately 
$1.5 billion.

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

Net cash provided by operating activities

Net cash used in investing activities

Net cash used in financing activities

2019 vs. 2018

Net cash provided by operating activities decreased by $888 million in 
the year ended December 31, 2019, when compared to the same period 
last  year,  primarily  driven  by  a  decrease  in  customer  deposits  received 
of  $558  million  and  net  unfavorable  movements  in  working  capital  of 
$352 million.

In the year ended December 31, 2019, net cash used in investing activities 
decreased  by  $996  million,  primarily  driven  by  lower  acquisition  and 
capital  expenditures  of  $842  million  and  $264  million,  respectively, 
partially  offset  by  the  absence  of  cash  received  of  $196  million  for  a 
contingent consideration asset, when compared to the prior year.

Net cash used in financing activities decreased by $1,948 million in the 
year  ended  December  31,  2019,  when  compared  to  the  same  period 
last  year.  The  primary  drivers  were  lower  share  repurchases,  down 
$1,287 million, lower debt repayments, down $329 million and increased 
borrowing, up $346 million.

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,  2019,  this  plan  accounted  for  76% 
of  our  consolidated  defined  benefit  pension  plans’  projected  benefit 
obligation and 86% of the related plans’ assets.

In  2019,  we  made  no  voluntary  contributions  to  our  domestic  defined 
benefit  pension  plan  and  cash  contributions  of  $2  million  to  our 
international  pension  plans.  During  2020,  we  anticipate  making  cash 
contributions  of  $85  million  to  our  U.S.  qualified  pension  plan  and 
$54 million to our international pension plans.

Management Assessment of Liquidity
We ended the fourth quarter of 2019 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,  2019, 
approximately 51% of the consolidated amount was held outside of the 
United States.

To  manage  interest  rate  exposure,  the  Company,  from  time  to  time, 
enters  into  interest  rate  swap  agreements.  As  of  December  31,  2019, 
there are no interest rate swaps outstanding.

Our  Revolving  Credit  Agreement  provides  a  committed  $1.5  billion 
unsecured  multi-currency  line  of  credit  and  expires  August  15,  2023. 
At  December  31,  2019,  there  were  no  outstanding  amounts  under  the 
Revolving Credit Agreement.

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, 2019, Corning did not have outstanding commercial paper.

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

the  year  ended  December  31,  2019, 

the  Company 
During 
repurchased  31.0  million  shares  of  common  stock  on  the  open 
market  for  approximately  $0.9  billion  as  part  of  its  2018  and  2019 
Repurchase Programs.

Refer  to  Note  16  (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. 
From time to time, we factor accounts receivable. During 2019, Corning 
participated  in  customer-initiated  payment  programs  which  resulted 
in  accelerated  collections  of  $143  million  in  accounts  receivable.  We 
currently  have  not  identified  any  potential  material  impact  on  our 
liquidity resulting from customer credit issues.

Our major source of funding for 2020 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, 2019, our leverage using this measure 
was approximately 37%. As of December 31, 2019, 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  exceeding  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, 2019, 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.

CORNING 2019 ANNUAL REPORTManagement’s Discussion and Analysis of Financial Condition and Results of Operations

Translated Earnings Contracts
Corning  has  hedged  a  significant  portion  of 
its  projected  yen 
exposure for the period 2019 through 2023, with average rate forwards 
and  options.  In  the  years  ended  December  31,  2019  and  2018,  we 
recorded  pre-tax  net  gains  of  $201  million  and  pre-tax  net  losses  of 
$96  million,  respectively,  related  to  changes  in  the  fair  value  of  these 
instruments. Included in these amounts are realized losses of $7 million 
and realized gains of $64 million, respectively. The gross notional value 
outstanding  for  these  instruments  which  hedge  our  exposure  to  the 
Japanese  yen  at  December  31,  2019  and  2018,  was  $10.2  billion  and 
$11.6 billion, respectively.

We  have  entered  into  average  rate  forwards  to  hedge  our  translation 
exposure  resulting  from  movements  in  the  South  Korean  won  and  its 
impact  on  our  net  income.  In  the  years  ended  December  31,  2019  and 
2018, we recorded a pre-tax net gain of $6 million and a pre-tax net loss 
of $26 million, respectively, related to changes in the fair value of these 
instruments.  Included  in  these  amounts  is  a  realized  loss  of  $1  million 
and a realized gain of $46 million, respectively. These instruments had a 
gross notional value outstanding at December 31, 2019 and 2018, of $0.4 
and $0.1 billion, respectively.

We  have  entered  into  a  portfolio  of  average  rate  forwards  to  hedge 
against our euro translation exposure. In the years ended December 31, 
2019 and 2018, we recorded pre-tax gains of $37 million and $43 million, 
respectively. Included in these amounts are realized gains of $29 million 
and  realized  losses  of  $14  million,  respectively.  At  December  31,  2019 
and 2018, the euro-denominated average rate instruments had a gross 
notional amount of $1.3 billion and $1.2 billion, respectively.

These derivative instruments are not designated as accounting hedges, 
and  changes  in  fair  value  are  recorded  in  earnings  in  the  translated 
earnings contract gain (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  and 
indemnity  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 13 (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 financial statements.

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

(1)  At December 31, 2019, we had stand-by letters of credit commitments of $82 million; $39 million was included in other accrued liabilities on our 

consolidated balance sheets.

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

take-or-pay contracts.

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

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

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

in the respective debt instruments.

(6) At December 31, 2019, $58 million was included on our consolidated balance sheets related to uncertain tax positions.

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

Environment

Refer to Item 3. Legal Proceedings or Note 13 (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.

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.

30

31

CORNING 2019 ANNUAL REPORTManagement’s Discussion and Analysis of Financial Condition and Results of Operations

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.

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, if applicable. 
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,  2019  and  2018,  the  carrying  value  of  precious  metals 
was lower than the fair market value by $849 million and higher than 
the fair market value by $719 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.

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.

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 cash flow and translation exposure 
resulting  from  movements  in  the  Japanese  yen,  South  Korean  won,  euro, 
new Taiwan dollar, Chinese yuan and British pound. Changes in the fair value 
of contracts designated as cash flow hedges are recorded in accumulated 
other comprehensive income in shareholders’ equity and reclassified into 
income when the underlying hedged item impacts earnings. For contracts 
that  are  not  designated  as  accounting  hedges,  changes  in  fair  value  are 
recorded  in  earnings  in  the  translated  earnings  contract  gain  (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 15 (Fair Value Measurements) to the consolidated financial 
statements for additional information.

CORNING 2019 ANNUAL REPORT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  accumulated  other  comprehensive 
income in shareholders’ equity on an annual basis and amortize them 
into our operating results over the average remaining service period of 
employees expected  to receive benefits under  the plans,  to  the extent 
such gains and losses are outside of the corridor.

CORNING 2019 ANNUAL REPORT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:

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

- 3 million
+ 2 million
+ 8 million
- 8 million

Effect on 
December 31, 2019 PBO
+ 110 million
- 105 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, 2019, a 25 basis point decrease in each spot 
rate would decrease shareholders’ equity by $133 million before tax, and 
a 25 basis point increase in each spot rate would increase shareholders’ 
equity by $127 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:

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 the new revenue standard 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 adopted the new revenue standard on 
January 1, 2019. The impact of adopting the new standard to Corning’s 
financial  statements  was  a  net  reduction  of  $186  million  to  2019 
beginning retained earnings. Timing of revenue recognition for certain 
open performance obligations as measured at January 1, 2019 under the 
new standard was approximately $239 million with offsetting deferred 
tax impacts of $53 million.

CORNING 2019 ANNUAL REPORTQuantitative and Qualitative Disclosures About 
Market Risks

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

• Exchange rate movements on financial instruments and transactions 

denominated in foreign currencies that impact earnings; and

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

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

We  are  exposed  to  potential  losses  in  the  event  of  non-performance 
by  our  counterparties  to  these  derivative  contracts.  However,  we 
minimize  this  risk  by  maintaining  a  diverse  group  of  highly-rated 
major 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  hedged  instruments. These  contracts  are  used  to  offset 
economic  currency  risks. 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 exposures. 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,  2019, 
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 $1.3 billion compared to $1.1 billion at December 31, 2018. 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 at December 31, 2019 and 2018. 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. As of December 31, 2019, there 
were no interest rate derivatives agreements outstanding.

CORNING 2019 ANNUAL REPORTManagement’s Annual Report on Internal Control Over 
Financial Reporting

Management is responsible for establishing and maintaining adequate 
internal control over financial reporting for Corning.

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 
Company’s  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. Based on this evaluation, management concluded that the 
Company’s internal control over financial reporting was effective as of 
December 31, 2019. The effectiveness of the Company’s internal control 
over  financial  reporting  as  of  December  31,  2019  has  been  audited  by 
PricewaterhouseCoopers  LLP,  an  independent  registered  accounting 
firm, as stated in their report and is included herein.

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,  2019 
and  2018,  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, 
2019,  including  the  related  notes  and  schedule  of  valuation  and 
qualifying  accounts  for  each  of  the  three  years  in  the  period  ended 
December  31,  2019  listed  in  the  accompanying  index  (collectively 
referred  to  as  the  “consolidated  financial  statements”).  We  also  have 
audited  the  Company’s  internal  control  over  financial  reporting  as  of 
December  31,  2019,  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,  2019  and  2018,  and  the  results  of  its 
operations and its cash flows for each of the three years in the period 
ended  December  31,  2019  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, 2019, based on criteria 
established in Internal Control - Integrated Framework (2013) issued by 
the COSO.

Basis for Opinions

The  Company’s  management  is  responsible  for  these  consolidated 
financial  statements,  for  maintaining  effective  internal  control  over 
financial  reporting,  and  for  its  assessment  of  the  effectiveness  of 
internal  control  over  financial  reporting,  included  in  Management’s 
Annual  Report  on  Internal  Control  Over  Financial  Reporting  appearing 
under  Item  9A.  Our  responsibility  is  to  express  opinions  on  the 
Company’s  consolidated  financial  statements  and  on  the  Company’s 
internal control over financial reporting based on our audits. We are a 
public accounting firm registered with the Public Company Accounting 
Oversight  Board  (United  States)  (PCAOB)  and  are  required  to  be 
independent with respect to the Company in accordance with the U.S. 
federal securities laws and  the applicable rules and regulations of  the 
Securities and Exchange Commission and the PCAOB.

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

Our  audits  of  the  consolidated  financial  statements 
included 
performing  procedures  to  assess  the  risks  of  material  misstatement 
of  the  consolidated  financial  statements,  whether  due  to  error  or 
fraud,  and  performing  procedures  that  respond  to  those  risks.  Such 
procedures  included  examining,  on  a  test  basis,  evidence  regarding 
the amounts and disclosures in the consolidated financial statements. 
Our  audits  also  included  evaluating  the  accounting  principles  used 
and significant estimates made by management, as well as evaluating 
the  overall  presentation  of  the  consolidated  financial  statements.  Our 
audit of internal control over financial reporting included obtaining an 
understanding  of  internal  control  over  financial  reporting,  assessing 
the  risk  that  a  material  weakness  exists,  and  testing  and  evaluating 
the design and operating effectiveness of internal control based on the 
assessed risk. Our audits also included performing such other procedures 
as  we  considered  necessary  in  the  circumstances. We  believe  that  our 
audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over 
Financial Reporting

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

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

Critical Audit Matters

The  critical  audit  matters  communicated  below  are  matters  arising 
from the current period audit of the consolidated financial statements 
that were communicated or required to be communicated to the audit 
committee and that (i) relate to accounts or disclosures that are material 
to the consolidated financial statements and (ii) involved our especially 
challenging,  subjective,  or  complex  judgments.  The  communication 
of  critical  audit  matters  does  not  alter  in  any  way  our  opinion  on  the 
consolidated  financial  statements,  taken  as  a  whole,  and  we  are  not, 
by communicating the critical audit matters below, providing separate 
opinions on the critical audit matters or on the accounts or disclosures 
to which they relate.

Income Taxes - Receivables for South Korean Tax Disputes

As described in Notes 1, 5, and 10 to the consolidated financial statements, 
in  evaluating  the  tax  benefits  associated  with  the  Company’s  various 
tax  filing  positions,  management  records  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  the  liability 
for  unrecognized  tax  benefits  in  the  period  in  which  management 
determines 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. The Company is currently 
appealing certain South Korean tax assessments and tax refund claims 
for tax years 2010 through 2018. 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.  Management  believes  that  it  is 
more likely than not that these tax positions will prevail in the appeal 
process and as a result, management recorded a non-current receivable 
of  $415  million  as  of  December  31,  2019  for  the  amount  on  deposit 
with  the  South  Korean  government.  In  the  fourth  quarter  of  2019, 
the  Company  received  a  refund  of  $38  million  from  the  South  Korean 
government related to tax years 2006 through 2009. As of December 31, 
2019, management has also recorded a current receivable of $33 million 
for an amount refunded in January 2020 related to the same issue for 
the tax year 2015.

The  principal  considerations  for  our  determination  that  performing 
procedures relating to the receivables for South Korean tax disputes is a 
critical audit matter are there was significant judgment by management 
when  applying  the  more  likely  than  not  recognition  criteria  to  the 
Company’s uncertain tax positions based on the application of the tax 
law. This in turn led to a high degree of auditor judgment, subjectivity, 
and  effort  in  performing  procedures  and  evaluating  audit  evidence 
relating  to  management’s  assumption  that  the  Company  will  prevail 
in  the  appeal  of  any  tax  assessments.  In  addition,  the  audit  effort 
involved  the  use  of  professionals  with  specialized  skill  and  knowledge 
to  assist  in  performing  these  procedures  and  evaluating  the  audit 
evidence obtained.

Addressing the matter involved performing procedures and evaluating 
audit evidence in connection with forming our overall opinion on the 
consolidated financial statements. These procedures included testing 
the  effectiveness  of  controls  relating  to  uncertain  tax  positions, 
including  management’s  assessment  of  the  South  Korean  tax 
disputes.  These  procedures  also  included,  among  others,  obtaining 
management’s  assessment  and  evidence  supporting  the  more-
likely-than-not  tax  position  on  the  South  Korean  tax  disputes  and 
evaluating the reasonableness of the likelihood that the tax positions 
will  ultimately  be  sustained  upon  examination  by  the  South  Korean 
tax  authorities  and  through  the  appeal  process.  Professionals  with 
specialized  skill  and  knowledge  were  used  to  assist  in  evaluating 
management’s  assessment  and  supporting  evidence, 
including 
application of the tax law.

Impairment at the Equity Method Investee, Hemlock 
Semiconductor Group - The Long-lived Asset Impairment of the 
Solar Power Panel Asset Group (“Solar Group”) 

As described in Notes 1 and 6 to the consolidated financial statements, 
the Company’s 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. Hemlock Semiconductor LLC and Hemlock 
Semiconductor  Operations  LLC,  of  which  the  Company  has  49.9% 
and  40.25%  ownerships  respectively,  are  recorded  as  equity  method 
investments  and  are  affiliated  companies  of  Hemlock  Semiconductor 
Group  (HSG).  Due  to  the  adverse  change  in  HSG’s  solar  business,  HSG 
was required  to assess  the recoverability of its long-lived assets in  the 
fourth  quarter.  Based  on  this  assessment,  HSG  determined  that  the 
carrying values of HSG’s Solar Group significantly exceeded its fair value. 
HSG  engaged  a  third-party  appraiser  to  assist  in  determining  the  fair 
value  of  the  assets  within  the  Solar  Group  based  on  the  highest  and 
best use of the asset group. As a result of the fair value determination, 
HSG  recognized  pre-tax  asset  impairment  charges  of  $916  million  for 
the year ended December 31, 2019. The Company’s share of the pre-tax 
impairment was $369 million.

The  principal  considerations  for  our  determination  that  performing 
procedures  relating  to  HSG’s  long-lived  asset  impairment  of  the  Solar 
Group is a critical audit matter are there was a high degree of auditor 
judgment,  subjectivity,  and  effort  in  performing  procedures  and 
evaluating  audit  evidence  relating  to  (i)  management’s  assessment  of 
the impairment at HSG, and (ii) the determination of the asset groups 
and the fair value of the assets within HSG’s Solar Group, including the 
assumptions related to the highest and best use of the assets. In addition, 
the audit effort involved  the use of professionals with specialized skill 
and knowledge to assist in performing these procedures and evaluating 
the audit evidence obtained.

Addressing the matter involved performing procedures and evaluating 
audit  evidence  in  connection  with  forming  our  overall  opinion  on  the 
consolidated  financial  statements.  These  procedures  included  testing 
the effectiveness of controls relating to the equity method investment 
accounting,  including  controls  over  management’s  recording  of  the 
Company’s share of the pre-tax impairment at HSG’s Solar Group. These 
procedures  also  included,  among  others,  (i)  evaluating  management’s 
assessment  of  the  impairment  at  HSG  and  the  Company’s  share  of 
the pre-tax impairment, and (ii) testing HSG’s process for determining 
the  fair  value  of  the  long-lived  assets  within  HSG’s  Solar  Group. 
Testing  the  fair  value  of  these  long-lived  assets  included  determining 
the  appropriateness  of  the  asset  groups  and  reasonableness  of  the 
assumptions related to the determination of the fair value of the long-
lived  assets  in  the  Solar  Group  based  on  their  highest  and  best  use. 
Professionals with specialized skill and knowledge were used  to assist

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

Corning Incorporated and Subsidiary Companies

1.  Summary of Significant Accounting Policies

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

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

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

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.

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.

Leases
Corning  leases  certain  real  estate,  vehicles,  and  equipment  from  third 
parties.  On  January  1,  2019  we  adopted  the  new  leasing  standard. 
Corning  classifies  leases  as  either  financing  or  operating.  Operating 
leases  are  included  in  other  assets  with  the  corresponding  liability  in 
other accrued liabilities and other liabilities on our consolidated balance 
sheets.  Finance  leases  are  included  in  property,  plant  and  equipment 

with  the  corresponding  liability  in  the  current  portion  and  long-term 
debt line items on our consolidated balance sheets. Leases where we are 
the lessor are not significant.

Lease expense is recognized on a straight-line basis over the lease term 
for  operating  leases.  Financing  leases  are  recognized  on  the  effective 
interest method for interest expense and straight-line method for asset 
amortization. Renewals and terminations are included in the calculation 
of the Right of Use (“ROU”) assets and lease liabilities when considered to 
be reasonably certain to be exercised. When the implicit rate is unknown, 
we use our incremental borrowing rate based on commencement date 
in determining the present value of lease payments.

Our  leases  do  not  include  residual  value  guarantees.  We  are  not  the 
primary beneficiary in or have other forms of variable interests with the 
lessor of the leased assets. The impact to the balance sheet for operating 
leases is a gross-up for the addition of ROU assets and liabilities relating 
to the operating leases in the amount of $449 million at adoption. The 
impact to the balance sheet for financing leases was not material.

Corning  elected  the  following  practical  expedients  and  accounting 
policy  elections  to  apply  the  new  lease  accounting  standard  at  its 
effective date as of January 1, 2019:

• Leases of less than 12 months in duration to be recorded as expense only;

• Account for lease and non-lease components of a contract as a single 

lease component; and

• Comparative  reporting  of  prior  periods  was  not  restated  due  to 

modified retrospective implementation.

At adoption, Corning recorded a nominal cumulative-effect adjustment 
to beginning retained earnings.

Refer  to  Note  4  (Leases)  to  the  consolidated  financial  statements  for 
additional information.

Revenue
One of Corning’s equity affiliates adopted the new revenue standard on 
January 1, 2019. The impact of adopting the new standard to Corning’s 
financial  statements  was  a  net  reduction  of  $186  million  to  2019 
beginning retained earnings. Timing of revenue recognition for certain 
open performance obligations as measured at January 1, 2019 under the 
new standard was approximately $239 million with offsetting deferred 
tax impacts of $53 million.

Income Taxes
In February 2018, the FASB issued a new standard for Income Statement 
-  Reporting  Comprehensive  Income,  which  allows  for  reclassification 
from  accumulated  other  comprehensive  income  to  retained  earnings 
for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. 
We  adopted  this  new  standard  effective  January  1,  2019.  The  impact 
of  the  new  standard  resulted  in  a  reclassification  of  $53  million  from 
accumulated  other  comprehensive  income  (“AOCI”)  to  beginning 
retained earnings.

CORNING 2019 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. 
Research and development costs totaled $833 million, $807 million and 
$689 million in 2019, 2018 and 2017, respectively.

Foreign Currency Translation and Transactions
The  determination  of  the  functional  currency  for  Corning’s  foreign 
subsidiaries  is  made  based  on  the  appropriate  economic  factors.  For 
most  foreign  operations,  the  local  currencies  are  generally  considered 
to be the functional currencies. Corning’s most significant exception is 
our Taiwanese subsidiary, which uses the Japanese yen as its functional 

Notes to Consolidated Financial Statements

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  net  losses  of  $19  million  and  $43  million  for  foreign 
currency  transaction  activity  for  the  years  ended  December  31,  2019 
and 2018, respectively, and a net gain of $20 million for foreign currency 
transaction activity for the year ended December 31, 2017. 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,  2019,  there 
were  approximately  60  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  $56  million,  $51  million 
and  $46  million  for  the  years  ended  December  31,  2019,  2018  and 
2017,  respectively.  The  income  tax  benefit  realized  from  share-based 
compensation  was  not  significant  for  the  years  ended  December  31, 
2019, 2018 and 2017. Refer to Note 5 (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 year 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.

CORNING 2019 ANNUAL REPORT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 
year to ten years, and generally have contractual lives of one year 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 2019, 2018 and 2017, 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 
undiscounted 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.

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

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 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.

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

Impairment of Long-Lived Assets
We  review  the  recoverability  of  our  long-lived  assets,  such  as  plant 
and  equipment  and  intangible  assets,  when  events  or  changes  in 
circumstances occur that indicate the carrying value of the asset or asset 
group may not be recoverable. When impairment indicators are present, 
we  compare  estimated  undiscounted  future  cash  flows,  including  the 
eventual disposition of  the asset group at market value,  to  the assets’ 
carrying value to determine if the asset group is recoverable. For an asset 
group  that  fails  the  test  of  recoverability,  the  estimated  fair  value  of 
long-lived assets is determined using an “income approach” that starts 
with the forecast of all the expected future net cash flows including the 
eventual disposition at market value of long-lived assets, and 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.

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.

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

Property, Plant and Equipment, Net of 
Accumulated Depreciation
Land, buildings, and equipment, including precious metals, are recorded 
at  cost.  Depreciation  is  based  on  estimated  useful  lives  of  properties 
using the straight-line method. Except as described in Note 8 (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  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.

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

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 change, 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 accumulated other 
comprehensive income in shareholders’ equity 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  12  (Employee  Retirement  Plans)  to  the  consolidated 
financial statements for additional detail.

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

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

Generally,  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, (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,  and  (6)  future  distribution  would 
trigger a significant federal income inclusion to the U.S. shareholder.

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. Consequently, adjustments for asset recoverability 
are included in equity earnings. We require our material equity method 
affiliates to provide audited financial statements. 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 are measured at fair value 
on a nonrecurring basis when impaired, which include long-lived assets, 
goodwill, asset retirement obligations, equity method investments and 
other investments that we do not have significant influence.

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 non-performance.

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.

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

All  derivatives  are  recorded  at  fair  value  on  our  consolidated  balance 
sheets. 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 our 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  gain 
(loss), net and the other expense, net lines.

New Accounting Standards
In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit 
Losses  (Topic  326).  The  ASU  introduces  a  new  accounting  model,  the 
Current  Expected  Credit  Losses  model  (CECL),  which  requires  earlier 
recognition  of  credit  losses  and  additional  disclosures  related  to  credit 
risk. The CECL model utilizes a lifetime expected credit loss measurement 
objective  for  the  recognition  of  credit  losses  at  the  time  the  financial 
asset is originated or acquired. ASU 2016-13 is effective for annual period 
beginning  after  December  15,  2019,  including  interim  reporting  periods 
within  those  annual  reporting  periods.  We  expect  that  the  impact 
of  adoption  will  not  have  a  material  impact  on  Corning’s  financial 
statements. Adoption of the new standard is effective January 1, 2020.

2.  Revenue

Product Revenue (Point in Time)
Most  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. Product warranty liabilities were not 
material at December 31, 2019 and 2018.

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

Total Revenue
Constant-currency adjustment(1)

Net sales of reportable segments and All Other

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  obligations.  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. 
Revenue  recognized  in  the  years  ended  December  31,  2019  and  2018,  is 
presented based on ASC 606. Amounts for the year ended December 31, 
2017 are presented under the ASC 605 basis of revenue recognition.

CORNING 2019 ANNUAL REPORT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. 
Most  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.

Customer Deposits
As  of  December  31,  2019  and  2018,  Corning  had  customer  deposits  of 
approximately  $1.0  billion.  The  majority  of  these  were  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 10 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. In the year ended December 31, 2019, a credit memorandum of 
$37 million was issued; no such memorandums were issued in 2018. As of 
December 31, 2019 and 2018, $927 million and $922 million were recorded 
as other long-term liabilities, respectively. The remaining $104 million and 
$54 million, respectively, were classified as other current liabilities.

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 fulfillment costs and not as separate 
performance obligations under the terms of our revenue contracts due to

We  incurred  lease  expense  in  the  amount  of  $171  million  for  the  year 
ended  December  31,  2019.  Operating  and  Financing  lease  costs  were 
$148 million and $23 million, respectively, for the year ended December 31, 
2019.  Short-term  rental  expense,  for  agreements  less  than  one  year  in 
duration, was immaterial. Financing lease cost is comprised of expenses 
for depreciation of right-of-use assets and interest on lease liabilities, and 
these expenses were not material for the year ended December 31, 2019.

Cash paid for amounts included in  the measurement of lease liabilities 
totaled  $123  million  for  the  year  ended  December  31,  2019.  Operating 
cash outflows for operating leases were $105 million. Cash payments for

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, (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,  and  (6)  future  distribution  would 
trigger a significant federal income inclusion to the U.S. shareholder.

During  the  year,  Corning  finalized  agreements  with  various  tax 
authorities,  including  the  Internal  Revenue  Service  (“IRS”)  to  resolve 
its  2013-2014  audit  (which  was  preliminarily  agreed  to  in  2018). These 
agreements  resulted  in  Corning  reclassifying  certain  reserves  from 
tax  reserve  liability  to  income  tax  payable  and  releasing  certain  tax 
reserves. The  net  impact  of  these  was  a  $378  million  reduction  to  the 
tabular roll-forward.

Included  in  the  balance  at  December  31,  2019,  2018  and  2017  are 
$35 million, $263 million and $97 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, 
2019,  2018  and  2017  the  amount  recognized  in  interest  expense  and 
accrued for the payment of interest and penalties were not material.

52

53

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

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. 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. As of December 31, 
2019,  the company is not expecting any significant movements in  the 
uncertain tax benefits in the next twelve months.

Corning Incorporated, as the common parent company, and all 80%-or-
more-owned  of  its  U.S.  subsidiaries  join  in  the  filing  of  consolidated 
U.S. federal income  tax returns. The statute of limitations is closed for 
all  periods  ending  through  December  31,  2012.  All  returns  for  periods 
ended  through  December  31,  2014,  have  been  audited  by  and  settled 
with the 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.

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: China (2008), 
Japan (2012), Taiwan (2013) and South Korea (2013).

CPM  is  currently  appealing  certain  tax  assessments  and  tax  refund 
claims  for  tax  years  2010  through  2018.  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. We believe  that it 
is  more  likely  than  not  that  we  will  prevail  in  the  appeal  process,  and 
as  a  result  we  have  recorded  a  non-current  receivable  of  $415  million 
as  of  December  31,  2019  for  the  amount  on  deposit  with  the  South 
Korean government. In the fourth quarter of 2019, we received a refund 
of $38 million from the South Korean government related to tax years 
2006 to 2009. As of December 31, 2019, we have also recorded a current 
receivable of $33 million for an amount refunded in January 2020 related 
to the same issue for tax year 2015.

As of December 31, 2019 and 2018, the undistributed earnings of equity 
companies included in our retained earnings were not material.

Hemlock Semiconductor Group (“HSG”)

In  2016,  Corning  realigned  its  ownership  interest  in  Dow  Corning, 
exchanging its 50% interest in the joint venture between Corning and 
Dow Chemical for a newly formed company that holds a 49.9% interest 
in  Hemlock  Semiconductor  LLC  and  a  40.25%  interest  in  Hemlock 
Semiconductor  Operations  LLC  which  are  recorded  as  equity  method 
investments  of  Corning  and  are  affiliated  companies  of  HSG.  HSG 
manufactures  polysilicon  products  for  the  semiconductor  and  solar 
industries.  HSG’s  solar  business  primarily  serves  the  solar  power 
panel industry.

In  prior  years,  HSG’s  solar  and  semiconductor  customers  entered 
into  long-term  “take  or  pay”  contracts  which  included  up-front  cash 
payments  to  secure  capacity.  During  the  last  few  years,  and  more 
significantly  in  2019,  the  solar  power  panel  industry  experienced 
significant  over-capacity  in  the  market,  resulting  in  declining  sales 
volumes and market prices. As a result, HSG’s solar business experienced 
lower  market  penetration,  overall  price  declines,  and  settled  contracts 
with customers that had committed volume and fixed pricing above the 
current market price. While these settlements positively impacted HSG’s 
cash  flow  in  2019,  they  reduced  expectations  for  future  sales  in  HSG’s 
solar business.

Due  to  the  adverse  change  in  HSG’s  solar  business,  HSG  was  required 
to assess the recoverability of its long-lived assets in the fourth quarter. 
Based  on  this  assessment,  HSG  determined  that  the  carrying  values 
of  HSG’s  solar  asset  group  significantly  exceeded  its  fair  values.  HSG 
engaged a third-party appraiser to assist in determining the fair value 
of the assets within in the solar asset group based on the highest and 
best use of the asset group. As a result of the fair value determination, 
HSG  recognized  a  pre-tax  asset  impairment  charge  of  $916  million 
for  the  year  ended  December  31,  2019.  Corning’s  share  of  the  pre-tax 
impairment was $369 million.

Due  to  the  adverse  changes  above,  the  carrying  values  of  HSG’s  solar 
business  inventories  were  also  affected  resulting  in  an  inventory 
write-down of $257 million for  the year. Corning’s pre-tax share of  the 
provision was $105 million.

HSG  adopted  the  new  revenue  standard  on  January  1,  2019  and  the 
timing of HSG’s revenue recognition for certain remaining performance 
obligations  measured  at  January  1,  2019  was  deferred  for  recognition. 
This  deferral  reduced  the  carrying  amount  of  Corning’s  investment  in 
HSG  by  $239  million.  During  the  fourth  quarter,  a  significant  number 
of  the  performance  obligations  were  satisfied  and  $434  million  was 
recognized into HSG’s net income. Corning’s share of the equity earnings 
was $208 million.

In addition, HSG settled certain revenue contracts in the fourth quarter, 
resulting  in  settlement  gains  of  $383  million  in  net  income.  Corning’s 
share of the settlement gains was $185 million.

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

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 (loss). Supplemental pro forma information was 
not  provided  because  the  acquisition  was  not  material  to  Corning’s 
consolidated financial statements.

There were no material acquisitions completed in 2017.

of  intangible  assets  decreased  by  $107  million  during  the  year  ended 
December 31, 2019, primarily due to acquisitions of $9 million of patents 
and other intangible assets, offset by amortization of $113 million and 
foreign currency translation and other adjustments of $3 million.

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

South Korean tax deposits
CPM  is  currently  appealing  certain  tax  assessments  and  tax  refund 
claims  for  tax  years  2010  through  2018.  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. We believe  that it 
is  more  likely  than  not  that  we  will  prevail  in  the  appeal  process,  and 

as  a  result  we  recorded  a  non-current  receivable  of  $415  million  as  of 
December  31,  2019  for  the  amount  on  deposit  with  the  South  Korean 
government.  In  the  fourth  quarter  of  2019,  we  received  a  refund  of 
$38  million  from  the  South  Korean  government  related  to  tax  years 
2006 to 2009. As of December 31, 2019, we have also recorded a current 
receivable of $33 million for an amount refunded in January 2020 related 
to the same issue for tax year 2015.

Based on borrowing rates currently available to us for loans with similar 
terms and maturities,  the fair value of long-term debt was $8.5 billion 
and $6.0 billion at December 31, 2019 and 2018, respectively. The Company 
measures the fair value of its long-term debt using Level 2 inputs based 
primarily  on  current  market  yields  for  its  existing  debt  traded  in  the 
secondary market.

CORNING 2019 ANNUAL REPORTDebt Issuances and Retirements

2019

In  the  third  quarter  of  2019,  Corning 
yen-denominated debt securities (the “Notes”), as follows:

issued  two 

Japanese 

• ¥31.3  billion  1.153%  senior  unsecured  notes  with  a  maturity  of  12 

years; and

• ¥5.9 billion 1.513% senior unsecured notes with a maturity of 20 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  approximately 
$349 million and will be used for general corporate purposes. Payments 
of principal and interest on the Notes will be in Japanese yen, or should 
yen be unavailable due to circumstances beyond Corning’s control, a U.S. 
dollar equivalent.

In the fourth quarter of 2019, Corning issued two U.S. dollar-denominated 
debt securities (the “Notes”), as follows:

• $400  million  3.90%  senior  unsecured  notes  with  a  maturity  of  30 

years; and

• $1.1 billion 5.45% senior unsecured notes with a maturity of 60 years.

The net proceeds, after deducting offering expenses, were approximately 
$1.5  billion  and  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 2019, Corning redeemed $300 million of 4.25% 
notes due in 2020, paying a premium of $4.7 million by exercising our 
make-whole call. The bond redemption resulted in an $8.4 million loss 
during the same quarter.

2018

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

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

12.  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 exceeding the minimum requirements in order to 
achieve the Company’s long-term funding targets. In 2019, we made no 
voluntary  contributions  to  our  domestic  defined  benefit  pension  plan 
and cash contributions of $2 million to our international pension plans. 
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. During 2020, we anticipate 
making cash contributions of $85 million  to our U.S. qualified pension 
plan and $54 million to our international pension plans.

Notes to Consolidated Financial Statements

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

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 in 2019, paying a nominal call premium. The bond redemption 
incurred an insignificant loss during the fourth quarter of 2018.

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.

Corning  offers  postretirement  plans  that  provide  health  care  and 
life  insurance  benefits  for  retirees  and  eligible  dependents.  Certain 
employees may become eligible for such postretirement benefits upon 
reaching retirement age and service requirements. For current retirees 
(including  surviving  spouses)  and  active  employees  eligible  for  the 
salaried retiree medical program, we have placed a “cap” on the amount 
we  will  contribute  toward  retiree  medical  coverage  in  the  future. The 
cap is equal  to 120% of our 2005 contributions  toward retiree medical 
benefits.  Once  our  contributions  toward  salaried  retiree  medical  costs 
reach  this  cap,  impacted  retirees  will  have  to  pay  the  excess  amount 
in  addition  to  their  regular  contributions  for  coverage.  This  cap  was 
attained for post-65 retirees in 2008 and attained for pre-65 retirees in 
2010. Furthermore, employees hired or rehired on or after January 1, 2007 
will  be  eligible  for  Corning  retiree  medical  benefits  upon  retirement; 
however, these employees will pay 100% of the cost.

The Company expects to recognize $5 million of net prior service cost as 
a component of net periodic pension cost in 2020 for its defined benefit 
pension  plans.  The  Company  expects  to  recognize  $1  million  of  net 
actuarial loss and $6 million of net prior service credit as components of 
net periodic postretirement benefit cost in 2020.

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  hundreds  of  bonds  from  four  grading 
sources,  Moody’s,  S&P,  Fitch  and  the  Dominion  Bond  Rating  Service.  A 
bond will be included if at least half of the grades from these sources 
are Aa, non-callable bonds. The very highest 10% yields and the lowest 
40%  yields  are  excluded  from  the  curve  to  eliminate  outliers  in  the 
bond population.

Mortality  is  one  of  the  key  assumptions  used  in  valuing  liabilities  of 
retirement plans. It is used to assign a probability of payment for future 
plan  benefits  that  are  contingent  upon  participants’  survival. To  make 
this  assumption,  benefit  plan  sponsors  typically  use  a  base  mortality 
table and an improvement scale that adjusts the rates of mortality for 
future anticipated changes to historical death rates.

CORNING 2019 ANNUAL REPORT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 at year-end 2017. As the Society 
of  Actuaries  publishes  additional  mortality  improvement  scales  (i.e. 
MP-2019) and base mortality tables (i.e. Pri-2012), each year Corning has 
considered these revised schedules in setting its mortality assumptions. 
As of December 31, 2019, Corning decided to continue application of both 
its  future  improvement  scale  to  the  MP-2017  scale  and  base  mortality 
assumptions to the RP-2014 tables.

Notes to Consolidated Financial Statements

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 2019.

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

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 primarily made in public securities to 
ensure  adequate  liquidity  to  support  benefit  payments.  Domestic  and 
international  stocks  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 

One-percentage-

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

64%  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.

7%  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, 2019 and 2018, the amount of Corning common stock 
included in equity securities was not significant.

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

We are required, at the time a guarantee is issued, to recognize a liability 
for  the  fair  value  or  market  value  of  the  obligation  it  assumes.  In  the 
normal course of our business, we do not routinely provide significant 
third-party  guarantees.  Generally,  third-party  guarantees  provided  by 
Corning  are  limited  to  certain  financial  guarantees,  including  stand-
by  letters  of  credit  and  performance  bonds,  and  the  incurrence  of 
contingent liabilities in the form of purchase price adjustments related 
to  attainment  of  milestones.  These  guarantees  have  various  terms, 
and none of these guarantees are individually significant. We believe a 
significant  majority  of  these  guarantees  and  contingent  liabilities  will 
expire without being funded.

Product  warranty  liability  accruals  at  December  31,  2019  and  2018 
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, 
2019, 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. 

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 
$50  million  and  $35  million  were  made  in  June  2019  and  June  2018, 
respectively.  The  total  amount  of  remaining  payments  due  in  years 
2020 through 2023 is $135 million, of which $35 million will be paid in 
the  second  quarter  of  2020  and  is  classified  as  a  current  liability. The 
remaining $100 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,  2019  and  2018,  the  amount  of  the  reserve  for 
these  non-PCC  asbestos  claims  was  estimated  to  be  $98  million  and 
$146 million, respectively. The change in reserve reflects post-stay claim 
experience  and  a  reduction  in  expected  defense  costs.  The  reserve 
balance as of December 31, 2019 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. Following the realignment, Corning 
no  longer  owned  any  interest  in  Dow  Corning. 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, subject to certain conditions and limits.

Dow Corning Breast Implant Litigation

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

Under the terms of the Plan, Dow Corning has established and 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,  subject  to  certain  conditions  and  limits.  As  of  December  31, 
2019, Dow Corning had recorded a reserve for breast implant litigation 
of  $165  million.  As  a  result,  Corning  does  not  believe  its  indemnity 
obligation for Dow Corning’s breast implant litigation liability, if any, will 
be material.

Dow Corning Bankruptcy Pendency Interest Claims

As  a  separate  matter  arising  from  the  bankruptcy  proceedings,  Dow 
Corning has been defending claims asserted by commercial creditors who 
claimed 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. 
Dow Corning settled those claims as of September 30, 2019 and received 
approval  of  the  settlement  from  the  bankruptcy  court.  Corning  does 
not believe its indemnity obligation, if any, for Dow Corning’s liability to 
be material.

Dow Corning Environmental Claims

In  September  2019,  Dow  Corning  formally  notified  Corning  of  certain 
environmental matters for which Dow Corning asserts that it has or will 
experience losses arising from remediation and response at a number 
of sites. In the event Dow Corning is liable for these claims, Corning may 
be  required  to  indemnify  Dow  Corning  for  up  to  50%  of  that  liability, 
subject  to  certain  conditions  and  limits.  As  of  December  31,  2019,  the 
Company  cannot  estimate  the  fair  value  of  the  indemnification  owed 
to Dow Corning, if any.

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

Environmental Litigation
Corning  has  been  named  by  the  Environmental  Protection  Agency 
(the Agency) under the Superfund Act, or by state governments under 
similar  state  laws,  as  a  potentially  responsible  party  for  15  active 
hazardous  waste  sites.  Under  the  Superfund  Act,  all  parties  who  may 
have contributed any waste to a hazardous waste site, identified by the 
Agency,  are  jointly  and  severally  liable  for  the  cost  of  cleanup  unless 
the  Agency  agrees  otherwise.  It  is  Corning’s  policy  to  accrue  for  its 
estimated liability related to Superfund sites and other environmental 

liabilities related to property owned by Corning based on expert analysis 
and  continual  monitoring  by  both  internal  and  external  consultants. 
At  December  31,  2019  and  2018,  Corning  had  accrued  approximately 
$41 million (undiscounted) and $30 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.

14.  Hedging Activities

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

The areas in which exchange rate fluctuations affect us include:

• Financial  instruments  and  transactions  denominated  in  foreign 

currencies, which impact earnings; and

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

Our most significant foreign currency exposures relate to the Japanese 
yen,  South  Korean  won,  new  Taiwan  dollar,  Chinese  yuan,  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.

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.

Cash Flow Hedges
Our cash flow hedging activities utilize OTC foreign exchange forward 
contracts  to  reduce  the  risk  that  movements  in  exchange  rates  will 
adversely affect the net cash flows resulting from the sale of products to 
customers and purchases from suppliers. The total gross notional values 
for foreign currency cash flow hedges are $2.1 billion and $0.4 billion at 
December  31,  2019  and  2018,  respectively.  The  majority  of  our  foreign 
exchange forward contracts hedge a portion of the Company’s exposure 
to  the  Japanese  yen  denominated  sales  with  maturities  spanning 
the  years  2020-2023  and  with  gross  notional  values  of  $1.5  billion  at 
December 31, 2019. 

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  is  released  from  accumulated  other 
comprehensive income into earnings when the corresponding interest 
expense occurs each period.

Corning  uses  regression  analysis  or  critical  term  match  method 
to  assess  initial  hedge  effectiveness.  Following  the  inception  of  a 
hedging  relationship,  hedge  effectiveness  is  assessed  quarterly  based 
on  qualitative  factors.  Corning  defers  gains  and  losses  related  to  the 
cash  flow  hedges  into  accumulated  other  comprehensive  loss  on  the 
consolidated balance sheets until the hedged item impacts earnings. At 
December 31, 2019, the amount expected to be reclassified into earnings 
within the next 12 months is a pre-tax net gain of $30 million.

Undesignated Hedges
Corning also uses OTC foreign exchange forward and option contracts 
that  are  not  designated  as  hedged  instruments.  These  contracts  are 
used to offset economic currency risks. 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  2019 
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 2020-2023. As of December 31, 2019, the U.S. 
dollar gross notional value of the yen average rate forwards program is 
$7.7 billion and $2.5 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,  new 
Taiwan dollar and British pound translation on the Company’s projected 
net income. As of December 31, 2019, 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, 
South 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 gain (loss), net 
line of the consolidated statements of income (loss).

15.  Fair Value Measurements

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

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

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

For  the  year  ended  December  31,  2019,  assets  and  liabilities  that  were 
measured  using  unobservable  (Level  3)  inputs  resulted  in  unrealized 
gains  recognized  in  earnings  of  $21  million  for  a  renewable  energy 
derivative  contract  and  the  reversal  of  a  liability  for  contingent 
consideration of $20 million.

based on the highest and best use of the asset group. As a result, HSG 
recognized pre-tax asset impairment charges of $916 million for the year 
ended December 31, 2019. Corning’s share of the pre-tax impairment was 
$369 million. Refer to Note 6 (Investments) to the consolidated financial 
statements for additional information.

At  December  31,  2019,  HSG,  one  of  the  Company’s  equity  method 
affiliates, wrote down its long-lived assets to fair value on a nonrecurring 
basis. HSG engaged a third-party appraiser to assist in determining the 
fair  value  of  its  long-lived  assets  using  unobservable  (Level  3)  inputs 

There were no other significant financial assets and liabilities measured 
on  a  nonrecurring  basis  during  the  years  ended  December  31,  2019 
and 2018.

16.  Shareholders’ Equity

Common Stock Dividends
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.

On  February  5,  2020,  Corning’s  Board  of  Directors  declared  a  10.0% 
increase  in  the  Company’s  quarterly  common  stock  dividend,  which 
increased  the  quarterly  dividend  from  $0.20  to  $0.22  per  share  of 
common stock, beginning with the dividend paid in the first quarter of 
2020. This increase marks the ninth 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, 
2019,  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

2017 Share Repurchases

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.

2018 Share Repurchases

2019 Share Repurchases

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  as  part  of  its  2016  and  2018 
Repurchase Programs.

On  July  17,  2019,  Corning’s  Board  of  Directors  authorized  $5  billion 
in  share  repurchases  with  no  expiration  date  (the  “2019  Repurchase 
Program”).  During  the  year  ended  December  31,  2019,  the  Company 
repurchased  31.0  million  shares  of  common  stock  on  the  open 
market  for  approximately  $0.9  billion  as  part  of  its  2018  and  2019 
Repurchase Programs.

17.  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 is as follows (in millions, 
except per share amounts):

CORNING 2019 ANNUAL REPORTNotes to Consolidated Financial Statements

18.  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,  serum  and  reagents  enabling  workflow  solutions  for  drug 
discovery and bioproduction.

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.

We prepared the financial results for our reportable segments on a basis 
consistent with our internal disaggregation of financial information to 
assist our chief operating decision maker (“CODM”) in making internal 
operating decisions. The impact of changes in the Japanese yen, South 
Korean  won,  Chinese  yuan  and  new  Taiwan  dollar  are  excluded  from 

segment  sales  and  segment  net  income  for  the  Display  Technologies 
and  Specialty  Materials  segments. The  impact  of  changes  in  the  euro, 
Chinese yuan and Japanese yen are excluded from segment sales and 
segment  net  income  for  our  Environmental  Technologies  and  Life 
Sciences segments. In January 2019, we began presenting results of the 
Environmental Technologies and Life Sciences segments on a constant-
currency  basis  to  mitigate  the  translation  impact  on  these  segments’ 
sales and net income. We have not recast prior periods as the impact of 
fluctuations in these currencies were not material as compared to prior 
periods.  Certain  income  and  expenses  are  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 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;  certain  litigation,  regulatory  and  other 
legal  matters;  restructuring,  impairment  and  other  charges  or  credits; 
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 included the earnings of equity affiliates that are closely associated 
with our reportable segments in  the respective segment’s net income 
(loss). We  have  allocated  certain  common  expenses  among  reportable 
segments  differently  than  we  would  for  stand-alone  financial 
information.  Segment  net  income  (loss)  may  not  be  consistent  with 
measures used by other companies.
