General

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

Corning  is  a  global,  technology-based  corporation  that  operates  in  four
reportable   business  segments:   Telecommunications,   Display   Technologies,
Environmental Technologies and Life Sciences.

Telecommunications Segment

The  Telecommunications  segment  produces optical fiber and cable, and hardware
and equipment products for the worldwide  telecommunications  industry.  Corning
invented the world's  first  low-loss  optical  fiber more than 30 years ago and
offers a range of optical  fiber  technology  products  and  enhancements  for a
variety  of  applications,  including  premises,  fiber-to-the-premises  access,
metropolitan,   long-haul  and  submarine  networks.  Corning  makes  and  sells
InfiniCor(R)  fibers for local area networks,  data centers and central offices;
NexCor(TM) fiber for converged services networks, SMF-28e(R) single mode optical
fiber that provides  additional  transmission  wavelengths in  metropolitan  and
access networks;  MetroCor(R) fiber products for metropolitan networks;  LEAF(R)
optical fiber products for long-haul,  regional and metropolitan  networks;  and
Vascade(R)  submarine optical fibers for use in undersea  networks.  Corning has
two large optical fiber manufacturing facilities in North Carolina, as well as a
controlling interest in Shanghai Fiber Optics Co., Ltd. in China. As a result of
lowered  demand for optical  fiber  products,  in 2002  Corning  mothballed  its
optical fiber manufacturing  facility in Concord, North Carolina and transferred
certain  capabilities  to  its  Wilmington,  North  Carolina  facility.  Corning
believes that the Concord facility can be returned to productive capacity within
six to nine months of a decision to reopen.

A significant portion of Corning's optical fiber is sold to subsidiaries such as
CCS Holdings,  Inc. (Corning Cable Systems),  Corning Cable Systems  Verwaltungs
GmbH, and  Norddeutsche  Seekabelwerke  GmbH & Co., KG (NSW) or equity  ventures
such as Aberdare Fiber Optic Cables (Pty.) Ltd. in South Africa,  Advanced Cable
Systems  Corporation in Japan, and Chengdu CCS Optical Fiber Cable Co. in China.
The optical  fiber is cabled  prior to being sold in cable form.  The  remaining
fiber production is sold directly to end users or third party cablers around the
world.  Corning's cabling  operations include large facilities in North Carolina
and Germany and smaller regional locations or equity affiliates, including those
listed above.

Corning's hardware and equipment products include cable assemblies,  fiber optic
hardware, fiber optic connectors,  optical components and couplers, closures and
pedestals,   splice  and  test  equipment  and  other  accessories  for  optical
connectivity.  For copper  connectivity,  Corning's  products include subscriber
demarcation,  connection  and  protection  devices,  xDSL passive  solutions and
outside plant enclosures. Each of the product lines may be combined in Corning's
fiber-to-the-premises   solutions.  Corning  has  manufacturing  operations  for
hardware and equipment  products in North Carolina and Texas, as well as Europe,
Mexico,  China, and the Caribbean.  Corning Gilbert Inc. offers products for the
cable television  industry,  including coaxial  connectors and associated tools.
Corning  Gilbert  has  manufacturing   operations  for  coaxial  connectors  and
associated assembly tools in Arizona, Mexico and Denmark. Corning's controls and
connectors products include high performance oscillators and crystals for use in
various telecommunication  applications.  Corning manufactures these products in
Pennsylvania, Canada, China and Germany.

On July 31,  2003,  Corning  completed  the  sale of a  significant  portion  of
photonic  technologies  assets  and $22  million  in cash to Avanex  Corporation
(Avanex) in exchange for 21 million  shares of Avanex  common  stock.  Corning's
photonic  technologies  products  had  included  erbium  doped fiber  amplifiers
("EDFAs"),  Raman amplifier modules and pumps,  semiconductor optical amplifiers
for long-haul,  metropolitan  and access  markets,  and dispersion  compensation
devices for long-haul and  metropolitan  networks.  These photonic  technologies
products maintain and control light signals in optical fiber  telecommunications
systems.  These  products  were  made  primarily  by  Corning  in New  York  and
Massachusetts.  As of December 31, 2003, we had discontinued production of these
products.



The Telecommunications  segment represented approximately 46% of Corning's sales
for 2003.

Display Technologies Segment

Corning's Display  Technologies segment manufactures glass substrates for active
matrix liquid crystal displays,  which are used primarily in notebook computers,
flat panel desktop  monitors,  and liquid  crystal  display  (LCD)  televisions.
Corning's  facilities  in  Kentucky,  Japan and Taiwan and its 50%  interest  in
Samsung Corning Precision Glass Co., Ltd.  (Samsung Corning  Precision) in South
Korea  develop,  manufacture  and supply high  quality  glass  products  using a
proprietary  fusion  manufacturing  process and know-how.  Affiliates of Samsung
Electronics  Co.,  Ltd.  own the  remaining  50%  interest  in  Samsung  Corning
Precision,  which sells glass  primarily  to LCD panel  manufacturers  in Korea.
Panel manufacturers in the other leading LCD-producing areas of the world, Japan
and  Taiwan,  are  supplied  by  Corning.   The  Display   Technologies  segment
represented approximately 19% of Corning's sales for 2003.

Corning has consistently been a leader to market with new large-generation sized
substrates  used by our customers in the  production of larger LCDs for monitors
and  television.  The  company  continues  to be one of the first  with  product
innovations  that  help our  customers  produce  larger,  lighter,  thinner  and
higher-resolution  displays  more  affordably.  Glass  substrates  are currently
available  in  sizes  up  to  Generation  6,  with   Generation  7  planned  for
introduction in the second half of 2004. Large  generation  substrates allow LCD
manufacturers  to  produce  larger  and a greater  number  of  panels  from each
substrate.  This leads to dramatic  economies of scale for LCD manufacturers and
is expected to help lower display prices for consumers in the future. At the end
of 2003,  approximately 33% of Corning and Samsung Corning Precision's volume of
LCD glass was Generation 5 and higher.

Corning's proprietary  manufacturing  process,  known as fusion, was invented by
the company. It is the cornerstone of Corning's technology leadership in the LCD
industry.  The highly automated process yields superior quality glass substrates
with  pristine  surfaces,   as  well  as  excellent  dimensional  stability  and
uniformity - essential  attributes  for the production of  increasingly  larger,
high  performance  active matrix LCDs.  Corning's fusion process is scalable and
has proven to be the most effective process in producing larger size substrates.

LCD  glass  manufacturing  is  a  highly  capital  intensive  business.  Corning
continued to make  significant  investments to expand its liquid crystal display
glass facilities in response to increased  customer  demand.  The environment is
very  competitive  and  there  are high  barriers  to  entry,  such as access to
capital,  technology  know-how,  intellectual  property,  patents  and  customer
access.

Environmental Technologies Segment

Corning's  environmental products include ceramic technologies and solutions for
emissions and pollution control in mobile and stationary applications around the
world,   including  gasoline  and  diesel  substrate  and  filter  products.  As
regulations and laws on emission controls standards have tightened over time and
additional countries have instituted  requirements related to clean air, Corning
has continued to develop more  efficient  emission-control  catalytic  converter
substrates  products with higher  density and greater  surface area for improved
emissions controls.  Corning  manufactures these products in New York, Virginia,
China,  Germany and South Africa.  Cormetech  Inc., 50% owned by Corning and 50%
owned by  Mitsubishi  Heavy  Industries  Ltd.  of  Japan,  manufactures  ceramic
environmental  substrate products at its North Carolina and Tennessee facilities
for use in power  plants.  Corning is  investing  in new ceramic  substrate  and
filter  technologies  for diesel emission  control device  products,  with a new
production  facility in New York to produce such  products  for diesel  vehicles
worldwide. The Environmental  Technologies segment represented approximately 15%
of Corning's sales for 2003.

Life Sciences Segment

Life sciences  laboratory products include microplate  products,  coated slides,
filter  plates for genomics  sample  preparation,  plastic cell culture  dishes,
flasks,  cryogenic vials,  roller bottles,  mass cell culture  products,  liquid
handling instruments,  Pyrex(R) glass beakers, pipettors,  serological pipettes,
centrifuge  tubes and  laboratory  filtration  products.  Corning sells products
under 3 brands:  Corning,  Costar and Pyrex. Corning manufactures these products
in Maine,  New York,  England and Mexico and markets  them  worldwide  primarily
through  large   distributors  to  government   entities,   pharmaceutical   and
biotechnology  companies,  hospitals,  universities and other laboratories.  The
Life Sciences segment represented approximately 9% of Corning's sales for 2003.






Other Products

Other products made by Corning include  semiconductor  optics,  ophthalmic glass
and plastic products,  technical  products,  such as polarizing glass, glass for
high   temperature   applications   and  machinable   glass  ceramic   products.
Semiconductor optics manufactured by Corning include:  high-performance  optical
material products;  optical-based metrology instruments;  and optical assemblies
for  applications in the global  semiconductor  industry.  Corning's high purity
fused silica (HPFS(R)) materials applications include projection and illuminator
lens blanks  products used in  microlithography,  spacecraft  windows and optics
products used in high-energy laser fusion systems. Corning's ultra low expansion
glass  (ULE(R))  is used in  manufacturing  mirror  blanks  for use in space and
ground-based  systems.   Corning  also  makes  fluoride  crystals  products  and
fabricates  optical  components,   including  calcium  fluoride  products,   for
customers who make lasers and  projection and  illuminator  lens systems used in
scanner  and  stepper  systems.  Corning  Tropel  Corporation  (a  wholly  owned
operation) designs and manufactures  precision optical  components,  modules and
systems for  semiconductor  wafer and mask  inspection,  high energy  laser beam
delivery  and shaping,  and  components  for  precision  inspection  and optical
management systems.  Corning's semiconductor optics products are manufactured in
New  York.  Other  specialty  glass  products  include  glass  lens  and  window
components and assemblies.  Other specialty glass products are made in New York,

with  Saint  Gobain   Vitrage  S.A.  of  France   manufacture   smooth   cooktop
glass/ceramic products in France and in South Carolina.

Corning's conventional glass television business includes a 51% owned affiliate,
Corning  Asahi Video  Products  Company  (CAV),  a producer of glass  panels and
funnels for cathode ray television tubes in Pennsylvania.  CAV ceased production
in the  second  quarter of 2003.  Corning  also owns a 50%  interest  in Samsung
Corning Company,  Ltd. (Samsung Corning), a producer of glass panels and funnels
for cathode ray tubes for televisions and computer monitors,  with manufacturing
facilities in Korea,  Germany and Malaysia.  Samsung Electronics  Company,  Ltd.
owns the remaining 50% interest in Samsung Corning.

We manufacture and process products at more than 60 plants and 22 countries.

Additional  explanation  regarding Corning and our four segments is presented in
Management's  Discussion  and Analysis of Financial  Condition  under  Operating
Review  and  Results  of  Operations  and Note 21  (Operating  Segments)  to the
Consolidated Financial Statements.

Corporate Investments

Corning and The Dow Chemical Company (Dow Chemical) each own half of Dow Corning
Corporation  (Dow  Corning),  an equity  company in Michigan  that  manufactures
silicone products worldwide.  Dow Corning is expected to emerge from its Chapter

appears in the Legal Proceedings section.

Corning and PPG Industries, Inc. each own half of Pittsburgh Corning Corporation
(PCC), an equity company in Pennsylvania  that  manufactures  glass products for
architectural   and  industrial  uses.  PCC  filed  for  Chapter  11  bankruptcy
reorganization  in April 2000.  Additional  discussion  about PCC appears in the
Legal Proceedings  section.  Corning also owns half of Pittsburgh Corning Europe
N.V., a Belgian corporation that manufactures glass products for industrial uses
primarily in Europe.

Competition

Corning  competes  across  all of its  product  lines 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
its position through technology and product innovation.  For the future, Corning
believes  its  competitive  advantage  lies in its  commitment  to research  and
development,  its financial resources and its commitment to quality. There is no
assurance  that  Corning  will  be able  to  maintain  its  market  position  or
competitive advantage.

Telecommunications Segment

Competition  within the  telecommunications  equipment industry is intense among
several significant companies.  Corning is a leading competitor in the segment's
principal  product  lines.  Price and new product  innovations  are  significant
competitive factors. The continued downturn in the telecommunications  industry,
particularly in Europe and North America, has changed the competitive  landscape
by increasing  competition based upon pricing.  These competitive conditions are
likely to persist.

Corning is the largest  producer of optical fiber and cable products,  but faces
significant  competition  due to continued  excess capacity in the market place,
price  pressure  and  new  product  innovations.   Corning  obtained  the  first
significant  optical  fiber  patents and believes its large scale  manufacturing
experience,  fiber  process,  technology  leadership and  intellectual  property
assets yield cost advantages relative to several of its competitors. The primary
competing  producers  of optical  fiber  products are  Furukawa  OFS,  Fujikura,
Sumitomo,   Pirelli  and  Draka  Comteq.   Furukawa  OFS  is  Corning's  largest
competitor. For optical fiber cable products,  Corning's primary competitors are
Furukawa OFS, Pirelli, Draka Comteq, Alcoa Fujikura and Sumitomo.



For hardware and  equipment  products,  significant  competitors  are 3M Company
(3M), Tyco Electronics, OFS, CommScope, ADC Communications and Marconi.

Display Technologies Segment

Corning is the  largest  worldwide  producer  of active  matrix  liquid  crystal
display glass  substrates and that market position  remained  relatively  stable
over the past year. Corning believes it has competitive  advantages in LCD glass
substrate  products by  investing  in new  technologies,  offering a  consistent
source of reliable supply, using its proprietary fusion manufacturing process at
facilities  in  Kentucky,  Japan and Taiwan,  as well as Korea  through  Samsung
Corning Precision. This competitive advantage allows us to deliver glass that is
larger,  thinner and lighter weight with exceptional surface quality and process
attributes.  Asahi  Glass,  Nippon  Electric  Glass and NH Techno are  Corning's
principal competitors in display glass substrates. In addition, new entrants are
seeking to expand their presence in this business.

Environmental Technologies Segment

For  worldwide  automotive  ceramic  substrate  products,  Corning has a leading
market position that has remained  relatively stable over the past year. Corning
believes its competitive  advantage in automotive ceramic substrate products for
catalytic   converters  is  based  upon  global  presence,   customer   service,
engineering design services and product innovation. Corning has a leading market
position in ceramic  substrates  for heavy duty diesel  applications.  The light
duty  diesel  vehicle   market   opportunity   is  still   emerging.   Corning's
environmental  technologies products face principal competition from NGK, Denso,
Ibiden and Emitec.

Life Sciences Segment

Corning is a leading supplier of glass and plastic science laboratory  products,
with a growing  plastics  products  market presence in North America and Europe,
and a relatively  stable  laboratory glass products market presence during 2003.
Corning seeks to maintain competitive  advantages relative to its competitors by
emphasizing product quality,  product availability,  supply chain efficiency,  a
wide product line and superior  product  attributes.  For  laboratory  products,
Schott  Glaswerke,  Kimble,  Greiner  and  Becton  Dickinson  are the  principal
worldwide competitors.

Other Products

Corning is a leading  supplier of materials and products for lithography  optics
in the  semiconductor  industry  and that market  position  remained  relatively
stable  during the past year.  Corning  seeks to compete by  providing  superior
optical quality, leading optical designs and a local Corning presence supporting
its customers.  For Corning's  semiconductor optical material products,  general
specialty   glass/glass  ceramic  products  and  ophthalmic   products,   Schott
Glaswerke, Shin-Etsu Quartz Products, Hoya and Hereaus are the main competitors.

CAV was a producer of conventional  television  glass products in North America.
In 2003, its market position  declined due to competition  from Asian television
glass suppliers and as the market shifted from conventional cathode ray tubes to
flat panel cathode ray tubes and other  technologies.  CAV ceased  production in
June 2003.  Samsung Corning is the third largest  worldwide  producer of cathode
ray tube glass products for conventional  televisions.  Its relative competitive
position  has  remained  stable  over the past year,  although  there has been a
decline in sales.  Samsung Corning seeks to maintain its  competitive  advantage
through customer  support,  logistics  expertise and a lower cost  manufacturing
structure.  Nippon Electric Glass,  Asahi, and various other Asian manufacturers
compete with Samsung Corning.

Raw Materials

Corning's  production  of  specialty  glasses  and  related  materials  requires
significant quantities of energy and batch materials.

Although energy shortages have not been a problem recently, Corning has achieved
flexibility  through  important  engineering  changes to take  advantage  of the
lowest-cost energy source in most significant processes.  Specifically,  many of
Corning's  principal  manufacturing  processes  can now be operated with natural
gas, propane, oil or electricity, or a combination of these energy sources.

As  to  resources  (ores,   minerals,   and  processed  chemicals)  required  in
manufacturing  operations,   availability  appears  to  be  adequate.  Corning's
suppliers  from time to time may  experience  capacity  limitations in their own
operations,  or may  eliminate  certain  product  lines;  nevertheless,  Corning
believes it has adequate programs to ensure a reliable supply of batch chemicals
and raw materials. For many products, Corning has alternative glass compositions
that would allow  operations to continue  without  interruption  in the event of
specific materials shortages.



Certain key optical  components  used in the  manufacturing  of products  within
Corning's  Telecommunications  segment are  currently  sole sourced or available
only from a limited  number of  sources.  Any  future  difficulty  in  obtaining
sufficient  and  timely  delivery  of  components  could  result  in  delays  or
reductions in product shipments, or reduce Corning's gross margins.

Patents and Trademarks

Inventions by members of Corning's research and engineering staff have been, and
continue to be, important to the Company's growth.  Patents have been granted on
many of these inventions in the United States ("U.S.") and other countries. Some
of these patents have been licensed to other manufacturers,  including companies
in which Corning has equity  investments.  Many of the earlier  patents have now
expired,  but Corning continues to seek and obtain patents  protecting its newer
innovations.  In 2003, Corning was granted over 300 patents in the U.S. and over
400 patents in countries outside the U.S.

Each  business  segment  possesses  its own  patent  portfolio  that  provides a
competitive   advantage  in  protecting  Corning's   innovations.   Corning  has
historically  enforced,  and will continue to enforce, its intellectual property
rights.  At the end of 2003,  Corning  and its  subsidiaries  owned  over  6,000
unexpired  patents in various  countries of which over 3,000 were U.S.  patents.
Between 2004 and 2006,  approximately 4% of these patents will expire,  while at
the same time Corning intends to seek patents  protecting its newer innovations.
Worldwide,  Corning has over 3,000 patent applications in process, with over 850
in process in the U.S. As a result,  Corning  believes that its patent portfolio
will  continue  to  provide a  competitive  advantage  in  protecting  Corning's
innovation,  although  Corning's  competitors  in  each  of its  businesses  are
actively seeking patent protection as well.

The  Telecommunications  segment has over 3,600 patents in various  countries of
which  over  2,000  were U.S.  patents.  Although  no one  patent is  considered
material to this business  segment,  and new patents are  frequently  granted to
Corning,  some of the important issued U.S. patents in this segment include: (i)
patents  relating to optical fiber products  including  dispersion  compensating
fiber, low loss optical fiber and high data rate optical fiber and processes and
equipment for  manufacturing  optical fiber including methods for making optical
fiber preforms and methods for drawing,  cooling and winding optical fiber; (ii)
patents relating to packaging of lasers and designs for optical switch products;
(iii)  patents  relating  to optical  fiber  ribbons and methods for making such
ribbon,  fiber optic cable  designs and  methods for  installing  optical  fiber
cable; and (iv) patents relating to optical fiber and electrical  connectors and
associated methods of manufacture. While a particular U.S. patent related to one
type of low  loss  optical  fiber  will  expire  in  2004,  there is no group of
important  Telecommunications  segment  patents set to expire  between  2004 and
2006.

The Display  Technologies  segment has over 200 patents in various  countries of
which over 75 were U.S. patents.  Although no one patent is considered  material
to this business  segment,  and new patents are  frequently  granted to Corning,
some of the  important  issued  U.S.  patents in this  segment  include  patents
relating to glass  compositions  and methods for the use and manufacture of flat
panel glass for display applications.

The Environmental Technologies segment has over 500 patents in various countries
of which  over 225 were U.S.  patents.  Although  no one  patent  is  considered
material to this business  segment,  and new patents are  frequently  granted to
Corning,  some of the  important  issued U.S.  patents in this  segment  include
patents relating to cellular ceramic honeycomb  products,  together with ceramic
batch and binder system compositions,  honeycomb extrusion and firing processes,
and  honeycomb  extrusion  dies  and  equipment  for the  high-volume,  low-cost
manufacture  of such  products.  While a particular  U.S.  patent related to the
process of mixing and extruding  certain ceramic  materials will expire in 2004,
there is no group of  important  Environmental  segment  patents  set to  expire
between 2004 and 2006.

The Life  Sciences  segment has over 150 patents in various  countries  of which
over 50 were U.S. patents. Although no one patent is considered material to this
business segment, and new patents are frequently granted to Corning, some of the
important  issued  U.S.  patents in this  segment  include  patents  relating to
methods and  apparatus  for the  manufacture  and use of  scientific  laboratory
equipment  including  nucleic acid arrays,  multiwell  plates,  and cell culture
products.  There is no group of important Life Sciences  segment  patents set to
expire  between  2004 and  2006.  Many of these  patents  are used in  Corning's
operations  or are  licensed  for use by others,  and Corning is licensed to use
patents owned by others.  Corning has entered into cross licensing  arrangements
with some major competitors,  but the scope of such licenses has been limited to
specific product areas or technologies.

Corning's  principal   trademarks  include  the  following:   Corning,   Celcor,
Discovering  Beyond  Imagination,  Eagle  2000,  Eagle APT,  Flame of  Discovery
Design, HPFS, LEAF, Pyrex, SMF-28e, Steuben, Lanscape and Vycor.

Protection of the Environment

Corning  has a program to ensure  that its  facilities  are in  compliance  with
state, federal and foreign pollution-control  regulations. This program resulted
in capital and operating expenditures during the past several years. In order to
maintain  compliance with such regulations,  capital  expenditures for pollution
control in continuing  operations were  approximately $7 million in 2003 and are
estimated to be $14 million in 2004.



Corning's 2003 operating  results from  continuing  operations were charged with
approximately  $28 million for  depreciation,  maintenance,  waste  disposal and
other operating  expenses  associated with pollution  control.  Corning believes
that its compliance program will not place it at a competitive disadvantage.

Risk factors

Set forth below and  elsewhere in this  Current  Report on Form 8-K and in other
documents we file with the Securities and Exchange  Commission (SEC) are some of
the  principal  risks and  uncertainties  that could  cause our actual  business
results  to  differ  materially  from any  forward-looking  statements  or other
projections  contained in this Current  Report on Form 8-K. In addition,  future
results could be materially  affected by general industry and market conditions,
changes in laws or  accounting  rules,  general U.S.  and non-U.S.  economic and
political  conditions,  including a global  economic  slowdown,  fluctuation  of
interest  rates or  currency  exchange  rates,  terrorism,  political  unrest or
international conflicts, political instability or major health concerns, natural
disasters or other  disruptions  of expected  economic and business  conditions.
These risk factors should be considered in addition to our  cautionary  comments
concerning  forward-looking  statements  in this  Current  Report  on Form  8-K,
including  statements  related to  markets  for our  products  and trends in our
business  that  involve  a  number  of risks  and  uncertainties.  Our  separate
statement labeled Forward-Looking Statements should be considered in addition to
the statements below.

Our  sales  could be  negatively  impacted  if one or more of our key  customers
substantially reduce orders for our products

     Our customer base is relatively  concentrated with less than 10 significant
customers  accounting for a high  percentage  (greater than 50%) of net sales in
most of our businesses, including those purchasing liquid crystal display glass.
However,  no  individual  customer  accounts  for more than 10% of  consolidated
sales.

     Our Display  Technologies  and  Environmental  Technologies  segments  have
concentrated  customer bases. If we lose a significant  customer in any of these
businesses,  our sales could be negatively  impacted.  The Display  Technologies
segment manufactures and sells glass substrates to a concentrated  customer base
comprised of LCD panel makers primarily located in Japan and Taiwan.  LCD panels
are used in computer products,  such as notebook computers and desktop monitors,
consumer  electronics  products,  such as digital cameras and camcorders and car
navigation systems, and LCD televisions. For the six months ended June 30, 2004,
six LCD customers accounted for 76% of the Display Technologies segment sales.

     Although the sale of LCD glass  substrates  has  increased  from quarter to
quarter in 2003 and in 2004,  there can be no  assurance  that this upward trend
will continue.  Our customers are LCD panel makers, and as they switch to larger
size  glass,  the pace of their  orders may be uneven  while they  adjust  their
manufacturing processes and facilities.  Additionally,  consumer preferences for
panels of  differing  sizes,  or price or other  factors,  may lead to pauses in
market  growth from time to time.  There is further risk that our  customers may
not be able to maintain  profitable  operations or access sufficient  capital to
fund ongoing expansions.

     Over recent years,  most of our major  customers in the  Telecommunications
segment  have  reduced  their  purchases  of our  products  and  have  expressed
uncertainty  as to their  future  requirements.  As a  result,  our  sales  have
declined to their  current low levels,  and it is  difficult  to predict  future
sales accurately. The conditions contributing to this difficulty include:

     .    the prolonged downturn in the telecommunications industry;
     .    uncertainty   regarding  the  capital  spending  plans  of  the  major
          telecommunications carriers;
     .    potential changes in governmental regulations;
     .    the telecommunications carriers' current limited access to the capital
          required for expansion;
     .    June 2004 Chinese  Ministry of Commerce  preliminary  determination of
          dumping of certain U.S. optical fiber exports to China; and
     .    general market and economic uncertainty.

     While we have  responded  to the  depressed  telecommunications  market  by
reducing  excess capacity and cutting costs, we cannot assure you that our plans
will be successful in mitigating  the adverse  effects of a prolonged  downturn.
The continuing  downturn in the  telecommunications  industry may be more severe
and prolonged  than  expected.  If our net sales  continue to decline or our net
sales do not increase as planned, our ability to meet financial expectations for
future  periods  may be  impaired,  and we may need to impair  tangible  assets,
intangible assets or goodwill or record additional reserves against deferred tax
assets.






If we do not  successfully  adjust  our  manufacturing  volumes  and fixed  cost
structure,  or achieve  manufacturing  yields or sufficient product reliability,
our  operating  results could suffer,  and we may not achieve  profitability  as
anticipated

     In the economic and industry downturn for our  Telecommunications  segment,
we have responded to the softer market by cutting costs, including the reduction
of our manufacturing volumes. We continued to execute our restructuring plans in
2003.  We have closed two fiber  facilities  and  mothballed  another and closed
several  factories that made  photonics,  cabling or hardware and equipment.  In
2003, we reduced our workforce by 1,975 positions, and we have reduced more than
21,000  positions  since  2001.  We cannot  assure  you that our  plans  will be
successful  in mitigating  the adverse  effects of a softer  market,  nor can we
assure you that  additional  adjustments  and charges  will not be  necessary to
respond to further market changes.

     The LCD market continues to grow rapidly.  This growth is being driven,  in
part, by higher demand for LCD televisions,  for which our LCD customers require
larger size glass  substrates.  Based on events as of June 30, 2004,  we plan to
spend $750 million to $800 million in 2004 to expand our liquid crystal  display
glass facilities in response to increased customer demand.  During 2004, Corning
has held  discussions  with several of its customers to discuss how to meet this
demand.  As part of its discussions,  Corning has sought improved payment terms,
including deposits against orders, to provide a greater degree of assurance that
we are  effectively  building  capacity  to meet the needs of a rapidly  growing
industry.  There  can be no  assurance  that  Corning  will be able to pace  its
capacity  expansion  to the actual  demand  and,  while the  industry  has grown
rapidly,  it is possible  that glass  manufacturing  capacity may exceed  demand
during certain periods.

     In addition,  our  restructuring  programs and current  business  plans are
designed  to restore  profitability  and  improve  cash  flow,  but we cannot be
certain that this will occur or that we will return to positive cash flow at the
levels and in the time period we are targeting.

     The  manufacturing  of our  products  involves  highly  complex and precise
processes, requiring production in highly controlled and clean environments. Any
changes  in  our  manufacturing  processes  or  those  of  our  suppliers  could
significantly reduce our manufacturing  yields and product reliability.  In some
cases, existing  manufacturing may be insufficient to achieve the volume or cost
targets of our customers.  We will need to develop new  manufacturing  processes
and techniques to achieve targeted volume and cost levels.  While we continue to
fund projects to improve our manufacturing  techniques and processes, we may not
achieve cost levels in our manufacturing  activities that will fully satisfy our
customers.

We have incurred, and may in the future incur,  restructuring and other charges,
the amounts of which are difficult to predict accurately

     The telecommunications  industry was severely hampered from 2001 to 2003 by
continued excess manufacturing capacity, increased intensity of competition, and
growing  pressure on price and profits.  These  negative  trends are expected to
continue in 2004. In 2001 through 2003, we recorded  charges for  restructuring,
impairment of assets, and the write-off of cost and equity based investments.

     Our  ability to  forecast  our  customers'  needs for our  products  in the
current  economic and industry  environment is limited.  Our results in 2003 and
2002 included significant charges for impairment of long-lived assets, primarily
in the  Telecommunications  segment and the  conventional  television  glass and
specialty materials businesses.

     We  may  record  additional   charges  for  restructuring  or  other  asset
impairments if additional  actions become necessary to respond to align costs to
a reduced level of demand.

In the event we incur continued  operating losses, we may be unable to recognize
future  deferred  tax assets and may be  required  to  reassess  our  ability to
realize the deferred tax assets already recorded.

     At  December  31,  2003,  we had  recorded  gross  deferred  tax  assets of
approximately  $2.1 billion  with a valuation  allowance  of $469  million,  and
offset by deferred tax  liabilities of $201 million.  Net domestic  deferred tax
assets were approximately $1.3 billion. Although management expects the domestic
deferred  tax assets to be  realized  from  future  earnings,  currently  we are
generating  domestic  losses.  Our  forecast  of  domestic  income  is  based on
assumptions about and current trends in our operating  segments,  and we can not
assure  you that such  results  will be  achieved.  As a result,  we may  record
additional  material  deferred tax valuation  reserves that would reduce our net
income and shareholders equity. If we record such a valuation allowance, we will
also cease to recognize additional tax benefits on any losses in the U.S.






If the  markets for our  products  do not  develop and expand as we  anticipate,
demand for our products may decline further,  which would negatively  impact our
results of operations and financial performance

     The  markets  for  our  products  are  characterized  by  rapidly  changing
technologies,  evolving industry  government  standards and frequent new product
introductions.  Our success is expected to depend,  in substantial  part, on the
timely and successful introduction of new products, upgrades of current products
to comply with emerging industry  government  standards,  our ability to acquire
technologies  needed to remain  competitive and our ability to address competing
technologies  and products.  In addition,  the following  factors related to our
products and the markets for them, if not achieved, could have an adverse impact
on our results of operations and financial performance:

     .    our ability to introduce leading products such as glass substrates for
          liquid crystal  displays,  optical fiber and  environmental  substrate
          products that can command competitive prices in the marketplace;
     .    our ability to maintain  or achieve a favorable  mix of sales  between
          premium  and  non-premium  fiber  and new  large  generation  sizes of
          display glass;
     .    our ability to  continue  to develop new product  lines to address our
          customers'  diverse needs within the several  market  segments that we
          participate in, which requires a high level of innovation,  as well as
          the accurate anticipation of technological and market trends;
     .    our  ability  to  develop  new   products  in  response  to  favorable
          government regulations and laws driving customer demand,  particularly
          environmental  substrate  diesel filter products in the  Environmental
          Technologies   segment   and   Telecommunications   segment   products
          associated with fiber to the premises;
     .    our  ability  to  create  the   infrastructure   required  to  support
          anticipated growth in certain businesses:
     .    a downturn in demand for notebook computers;
     .    the rate of  substitution  by  end-users  purchasing  LCD  monitors to
          replace cathode ray tube monitors;
     .    the rate of growth in purchases of LCD  televisions  to replace  other
          technologies; or
     .    fluctuations  in  inventory  levels in the supply  chain of  LCD-based
          consumer electronics.

We face pricing pressures in each of our leading businesses that could adversely
affect our results of operations and financial performance

     We periodically face pricing pressures in each of our leading businesses as
a result of intense  competition,  emerging new technologies,  or over-capacity.
While we will work toward reducing our costs to respond to the pricing pressures
that may  continue,  we may not be able to achieve  proportionate  reductions in
costs.  As a result  of  overcapacity  and the  current  economic  and  industry
downturn in the Telecommunications  segment, pricing pressures continued in 2003
and 2004, particularly in our optical fiber and cable products. Pricing pressure
has also continued in our Display  Technologies  segment as the manufacturers of
desktop displays strive to reduce their costs.

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

     Acquisitions recorded as purchases for accounting purposes have resulted in
the  recognition  of  significant   amounts  of  goodwill  and  other  purchased
intangibles.  At December 31, 2003,  the  Telecommunications  operating  segment
goodwill  balance  was $1.6  billion,  and  goodwill  associated  with the other
segments was $159 million. The potential impairment of these assets could reduce
our net income and shareholders' equity.

     Effective January 1, 2002, we adopted Financial  Accounting Standards Board
Statement of Financial  Accounting  Standards  ("SFAS") No. 142,  "Goodwill  and
Other Intangible  Assets," pursuant to which goodwill is no longer amortized but
is  subject to  impairment  tests at least  annually.  The  goodwill  impairment
accounting  rules are  intricate  and require  that we make  certain  difficult,
subjective  and  complex  judgments  involving  a number of  matters,  including
assumptions  and  estimates  used to determine  the fair value of our  reporting
units. Under SFAS No. 142, goodwill is tested for impairment at a reporting unit
level.  The criteria for  establishing  a reporting unit is dependent upon how a
company determines its operating segments under SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information."  Specifically,  SFAS No. 142
permits a company to define a reporting unit as either an operating  segment,  a
component of an operating segment or an aggregation of two or more components of
an operating segment.  The reporting units include  Telecommunications,  Display
Technologies,  Environmental  Technologies,  specialty  materials,  conventional
video components and ophthalmic.

     During 2002, we completed our annual goodwill  impairment test,  determined
the  Telecommunications  goodwill  balance was impaired,  and recorded a related
impairment charge of $400 million. Our 2002 testing results also determined that
the goodwill related to the remaining  reporting units was not impaired.  In the
fourth quarter of 2003, we completed our annual  goodwill  impairment  tests and
determined  that the goodwill  balances were not impaired.  While we believe the
estimates and judgments about future cash flows used in the goodwill  impairment
tests are reasonable, we cannot provide assurance that future impairment charges
will not be  required  if the  expected  cash flow  estimates  as  projected  by
management do not occur or change based on market conditions.



     In June 2004, the Chinese  Ministry of Commerce (the  Ministry)  issued its
preliminary  determination  asserting  that  various  optical  fiber  producers,
including  Corning,  had dumped  optical  fiber in China.  That ruling  requires
Chinese  importers to make cash deposits of 16% of the single mode optical fiber
price to Chinese customs officials.  Should the preliminary determination become
final,   it   will   negatively   impact   our   long-term   outlook   for   the
Telecommunications   segment,   and  may  require  us  to  test   goodwill   for
recoverability.

We may be limited in our ability to obtain  additional  capital on  commercially
reasonable terms

     Although we believe  existing cash,  short-term  investments  and borrowing
capacity,  collectively,  provide adequate  resources to fund ongoing  operating
requirements,  we may be  required  to  seek  additional  financing  to  compete
effectively in our markets.  Our public debt ratings affect our ability to raise
capital and the cost of such capital.  In July 2002, Fitch downgraded our senior
unsecured  long-term debt rating from BBB- to BB;  Standard & Poor's  downgraded
our senior unsecured  long-term debt rating from BBB- to BB+ and short-term debt
credit rating from A-3 to B; and Moody's reduced our senior unsecured  long-term
debt rating from Baa3 to Ba2 and  short-term  debt credit rating from Prime-3 to
Not Prime. These and any further downgrades may increase our borrowing costs and
affect our ability to access the debt capital markets.

     As a result of our lower  debt  ratings,  we may face  difficulties  in our
business.  For  example,  we may  face  increasing  requirements  to  post  cash
collateral  for  performance  bonds  and some  customers  may  seek  alternative
suppliers.

     We are subject  under our  revolving  credit  facility  to a covenant  that
requires us to maintain a ratio of total debt to capital,  as defined  under the
credit  facility,  of not greater than 60%. Our total debt to capital  ratio was
31% at June 30,  2004.  This  covenant  may limit our  ability to borrow  funds.
Further declines or failure to recover in our  Telecommunications  segment could
cause  impairments  of  goodwill,  deferred tax assets,  tangible or  intangible
assets or  restructuring  charges  related to our overall  business.  Additional
impairments or charges could materially increase our total debt to capital ratio
which may reduce the amounts we are able to borrow  under the  revolving  credit
facility.

If  our  products  or  components   purchased  from  our  suppliers   experience
performance issues, our business will suffer

     Our  business   depends  on  the   production  of  excellent   products  of
consistently  high  quality.  To this end, our  products,  including  components
purchased  from  our  suppliers,  are  tested  for  quality  both  by us and our
customers.  Nevertheless,  our products are highly  complex,  and our customers'
testing  procedures  are limited to  evaluating  our  products  under likely and
foreseeable failure scenarios. For various reasons (including, among others, the
occurrence of performance problems  unforeseeable in testing),  our products and
components  purchased  from our  suppliers  may  fail to  perform  as  expected.
Performance  issues could result from faulty design or problems in manufacturing
or testing.  We have experienced such performance  issues in the past and remain
exposed  to  such  performance  issues.  In some  cases,  product  redesigns  or
additional  capital  equipment may be required to correct a defect. In addition,
any significant or systemic  product failure could result in customer  relations
problems and harm the future sales of our products.

Interruptions  of  supplies  from our key  suppliers  may affect our  results of
operations and financial performance

     Interruptions  of supplies from our key suppliers could disrupt  production
or impact our ability to increase production and sales. We do not have long-term
or volume purchase agreements with every supplier,  and may have limited options
for alternative supply if these suppliers fail, for any reason,  including their
business  failure  or  financial   difficulties,   to  continue  the  supply  of
components.

We face intense competition in most of our businesses

     We  expect  that  we  will  face  additional   competition   from  existing
competitors  and from a number of companies that may enter our markets.  Because
some of the markets in which we compete have been historically  characterized by
rapid growth and are  characterized by rapid technology  changes,  smaller niche
and start-up  companies may become our principal  competitors in the future.  We
must invest in research and development,  expand our engineering,  manufacturing
and marketing capabilities, and continue to improve customer service and support
in order to remain competitive.  While we expect to undertake the investment and
effort  in each of these  areas,  we cannot  assure  you that we will be able to
maintain or improve our competitive position.






We may experience difficulties in enforcing our intellectual property rights and
we may be subject to claims of infringement of the intellectual  property rights
of others

     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  assure you that the
patents that we hold or may obtain will provide  meaningful  protection  against
our  competitors  or  competitive  technologies.  Litigation may be necessary to
enforce our intellectual  property  rights,  to protect our trade secrets and to
determine  the  validity  and scope of our  proprietary  rights.  Litigation  is
inherently  uncertain and the outcome is often  unpredictable.  Other  companies
hold patents on technologies used in our industries and are aggressively seeking
to expand, enforce and license their patent portfolios.

     The  intellectual  property  rights of others could  inhibit our ability to
introduce new products.  We are, and may in the future be,  subject to claims of
intellectual  property infringement or misappropriation and we cannot assure you
as to the outcome of such claims. Litigation or claims against us could force us
to cease selling or using any of our products that  incorporate the intellectual
property  that is the  subject  of such  claims,  obtain a license  from a third
party,  or redesign or rename our products.  These actions,  if possible,  could
result in substantial costs or loss of revenue.

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

     Pending,   threatened   or  future   litigation   is  subject  to  inherent
uncertainties. Our financial condition or results of operations may be adversely
affected by unfavorable outcomes, expenses and costs exceeding amounts estimated
or  insured.  In  particular,  we have been  named as a  defendant  in  numerous
lawsuits  against PCC and several other  defendants  involving  claims  alleging
personal  injury from exposure to asbestos.  As described in Legal  Proceedings,
our negotiations with the  representatives of asbestos claimants have produced a
tentative settlement,  but certain cases may still be litigated.  Final approval
of a global settlement through the PCC bankruptcy process may impact the results
of operations for the period in which such costs, if any, are recognized.  Total
charges of $413 million ($263  million  after-tax)  have been  incurred  through
December 31, 2003; however,  the final settlement value will be dependent on the
price of our common stock at the time it is contributed to the settlement trust.
Management  cannot provide  assurances that the ultimate outcome of a settlement
will not be materially different from the amount recorded to date.

We face risks related to our international operations and sales

     We have customers and significant  operations,  including manufacturing and
sales,  located  outside the U.S.  We have large  manufacturing  operations  for
liquid crystal display glass  substrates in the Asia-Pacific  region,  including
equity  investments  in  companies  operating  in South  Korea that make  liquid
crystal display glass and in China that make  telecommunications  products,  and
several  significant  customers are located in this region. As a result of these
and other international operations, we face a number of risks, including:

     .    major health concerns such as SARS;
     .    difficulty of effectively managing our diverse global operations;
     .    change in regulatory requirements;
     .    tariffs, duties and other trade barriers;
     .    undeveloped legal systems; and
     .    political and economic instability in foreign markets.

We face risks from claims of dumping products in foreign markets

     We export  large  quantities  of  Telecommunications  segment  products  to
customers  outside the U.S. Customs duties,  tariffs and other trade barriers in
countries  outside the U.S.  affect our sales and profit levels,  as well as our
export  product  volume.  Our optical fiber exports to China may be reduced by a
June 2004  preliminary  ruling by the Chinese  Ministry of Commerce that various
optical fiber producers dumped products into China. That ruling requires Chinese
importers to make cash deposits of 16% of the single mode optical fiber price to
Chinese customs officials.






Our equity investments in companies that we do not control generated substantial
equity earnings

     Dow Corning (which makes silicone  products) and Samsung Corning  Precision
(which makes liquid crystal  display glass) are two companies in which we have a
50%  ownership  interest.  During  2003,  we  recognized  $226 million in equity
earnings  from  these  two  companies.  Dow  Corning  emerged  from  Chapter  11
bankruptcy proceedings in June 2004. Samsung Corning Precision is located in the
Asia-Pacific  region and, as such, is subject to those geographic risks referred
to above. We have equity  investments in other companies  within and outside the
U.S., and many of these have been successful operations over the years. With 50%
or lower ownership, we do not control such equity companies nor their management
and  operations.  Performance of our equity  investments may not continue at the
same levels in the  future.  During 2003 and 2004,  we have  recognized  charges
associated  with   restructuring   actions  and  bankruptcy  related  settlement
activities.  It is possible that future earnings could be negatively impacted by
additional charges, principally at Dow Corning and Samsung Corning Company, Ltd.

We face risks due to foreign currency fluctuations

     Because we have  significant  customers  and  operations  outside the U.S.,
fluctuations in foreign  currencies affect our sales and profit levels.  Foreign
exchange rates may make our products less  competitive in countries  where local
currencies decline in value relative to the dollar.

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

     In  2002  and  2003,  certain  of  our  customers   experienced   financial
difficulties, and some filed with the courts seeking protection under bankruptcy
or reorganization  laws. We have experienced,  and in the future may experience,
losses as a result of our inability to collect our accounts receivable,  as well
as the loss of such customer's  ongoing business.  If our customers fail to meet
their  payment  obligations  to us, we could  experience  reduced cash flows and
losses in excess of amounts  reserved.  As of December  31,  2003,  reserves for
trade receivables totaled approximately $38 million.

We may not have adequate insurance coverage for claims against us

     We face the risk of loss resulting from, and adverse  publicity  associated
with, product liability, securities, fiduciary liability, intellectual property,
antitrust, contractual,  warranty, fraud and other lawsuits, whether or not such
claims are valid. In addition, our product liability,  fiduciary,  directors and
officers,  property and  comprehensive  general  liability  insurance may not be
adequate to cover such claims or may not be  available  to the extent we expect.
Our insurance costs have increased  substantially and may increase  further.  We
may not be able to get adequate  insurance  coverage in the future at acceptable
costs.  A successful  claim that exceeds or is not covered by our policy  limits
could require us to pay  substantial  sums. Some of the carriers in our historic
excess insurance  program are not rated, or may have lower ratings,  and may not
be able to respond if we should have claims  reaching  into  excess  layers.  In
addition,  we may not be able to insure  against  certain  risks or obtain  some
types of insurance, such as terrorism insurance.

                                                                   ------------

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations  of the 2003  Annual  Report on Form 10-K,  revised  to  reflect  the
revisions in our reportable segments described herein.

Overview

Corning had three  significant  priorities  in 2003:  to protect  our  financial
health,  to restore  profitability,  and to invest in our  future.  We have made
significant progress towards all three in 2003.

Financial Health

We have improved our balance sheet in 2003 by substantially  decreasing our debt
from $4.2 billion at the beginning of the year to $2.8 billion.  We reduced debt
by using cash on hand and by completing equity offerings of 45 million shares of
our  common  stock for  proceeds  of $363  million in the third  quarter  and 50
million  shares of our common  stock for  proceeds of $267 million in the second
quarter. These actions improved our debt to capital ratio from 47% at the end of
2002 to 34% at the end of 2003.

We have $1.3 billion in cash and cash  equivalents  and short-term  investments,
access to a $2 billion  revolving  credit  facility  and  access to the  capital
markets.  Our major  source of funding for 2004 and beyond will be our  existing
balance of cash and short-term investments. From time to time, we may also issue
debt or equity  securities  to raise  additional  cash to fund a portion  of our
capital  expenditures  related  to our  growth  businesses.  We  believe we have
sufficient   liquidity   for  the  next  several   years  to  fund   operations,
restructuring  liabilities,  the asbestos  settlement,  research and development
expenditures, capital expenditures and scheduled debt repayments.

Profitability

On an  overall  basis,  we  believe  that  our  2003  results  reflect  positive
developments  including  significant growth in our Display Technologies segment,
stabilization in our  Telecommunications  segment, and exiting our photonics and
conventional  video  components  product  lines.  We incurred a net loss of $223
million,  or $0.18 per share in 2003 compared to a net loss of $1.3 billion,  or
$1.39 per share, in 2002, and a net loss of $5.5 billion, or $5.89 per share, in
2001. The improvements  were driven  primarily by a reduction in  restructuring,
impairment and other charges and credits to $111 million ($26 million  after-tax
and minority interest) in 2003 compared to $2.1 billion ($1.5 billion after-tax)
in 2002 and $5.7 billion ($5.3 billion after-tax) in 2001.

Our $223 million net loss in 2003 included the following:

..    a charge of $413 million  ($263 million  after-tax)  related to the pending
     asbestos  settlement of current and future tort claims in connection with a
     proposed  reorganization  plan for our Pittsburgh Corning Corporation (PCC)
     equity affiliate,
..    a net gain on repurchases  of debt of $19 million ($12 million  after-tax),
     and
..    an after-tax  charge in equity  earnings of $66 million related to an asset
     impairment  charge  recorded  by  Samsung  Corning  Company  Ltd.  (Samsung
     Corning),  a 50% owned equity venture which  manufactures glass funnels and
     panels for conventional television.

Sales in the  Telecommunications  segment have stabilized,  remaining relatively
flat from the third  quarter of 2002 to the fourth  quarter  2003.  We have been
able to reduce  the loss in the  Telecommunications  segment  in 2003 by closing
plants and reducing  costs.  Demand for many of our  products,  particularly  in
photonics,  remained  soft.  In July  2003,  we  completed  the sale of  certain
photonics  assets to Avanex,  and in December  2003,  our final shipment of pump
lasers for sale to Avanex was completed.

Sales and earnings in our Display Technologies segment improved primarily due to
the volume  growth  experienced  in this  segment.  Segment  sales grew from $93
million in the first  quarter of 2002 to $199  million in the fourth  quarter of
2003.  Offsetting  this  improvement,  the market for  conventional  televisions
declined.  As a result,  in 2003 we agreed with our partner to shutdown  Corning
Asahi Video Products Company (CAV), a 51% consolidated venture that manufactured
conventional  video  components  products.  In addition,  demand for high purity
fused silica and calcium  fluoride  products was lower than we had  anticipated.
Therefore,  we  decided  to  consolidate  the  operations  of our  semiconductor
materials products in the fourth quarter of 2003 to make our infrastructure more
flexible for the cyclical nature of this market.

Investing in our future

We remain  committed to investing in innovation,  and we are investing in a wide
variety of technologies  including liquid crystal  displays,  diesel filters and
substrates,  and the optical fiber,  cable, and hardware and equipment that will
enable fiber-to-the-premises. Although our spending in research, development and
engineering  has declined,  as a percentage  of sales it remains above  historic
levels.






We have also continued to invest in capital spending in the Display Technologies
and  Environmental  Technologies  segments.  Capital  spending  in 2003 and 2002
approximated $370 million and $360 million,  respectively, the majority of which
was to expand capacity for liquid crystal display glass and for new capacity for
diesel  substrates and filters.  As a result of market  expansion,  and based on
events as of June 30,  2004,  we expect our  consolidated  capital  spending  to
approximate  $950  million to $1 billion in 2004,  of which $750 million to $800
million will be to expand capacity for liquid crystal display glass production.

------------------------------------------------------------------------------------------------------------------------------------


Net sales

Consolidated  net sales for 2003 were $3.1  billion,  a  decrease  of 2%, or $74
million,  compared  to 2002.  Approximately  $158  million of the sales  decline
occurred in the photonic  technologies  and the  conventional  television  glass
products  that we  exited  during  2003.  Based  on the  exchange  rates  at the
beginning  of 2003,  our sales were  favorably  impacted by the  weakening  U.S.
dollar against the Yen and the Euro by approximately  $85 million.  Consolidated
net sales for 2002 were $3.2 billion,  a decrease of 48%, or $2.9 billion,  from
2001  sales of $6.0  billion.  The  sales  decline  was most  pronounced  in the
Telecommunications  segment where  significantly lower demand and price declines
for our optical fiber and cable and photonic  technologies products caused sales
to decrease in this segment by 63%, or $2.8 billion year to year.






Gross margin

As a  percentage  of net  sales,  gross  margin  improved  eight  points in 2003
compared to 2002. The  improvement  was driven by lower  depreciation  and other
fixed costs  resulting  from the 2002  restructuring  actions,  primarily in the
Telecommunications  segment.  Gross  margin  improved  in all  other  reportable
segments;  however,  the gains achieved were  partially  offset by a $13 million
write-down  of  inventory  related to the exit of CAV.  As a  percentage  of net
sales,  gross margin  decreased from 30% to 19% in 2002 compared to 2001.  Gross
margin was  impacted by lower sales  volumes in the  Telecommunications  segment
which were  insufficient to cover fixed  manufacturing  costs.  Downward pricing
pressure also negatively impacted gross margins,  primarily in the optical fiber
and cable products.  These negative trends were offset by significant fixed cost
reductions as  manufacturing  capacity was  shutdown.  Gross margin in the other
operating segments decreased approximately two points from 2001.

Selling, general and administrative expenses

Selling,  general and administrative expenses decreased 16%, or $117 million, in
2003 compared to 2002 and as a percentage  of sales  improved four points in the
same period.  The improvement  reflects cost savings primarily from the 2002 and
2003 restructuring  actions. SG&A expenses decreased 34% to $716 million in 2002
while SG&A  increased five points as a percentage of net sales to 23% over 2001.
The decrease in selling,  general and administrative  expenses for 2002 reflects
cost  savings  from the  restructuring  actions  which began in 2001,  while the
increase as a percentage of net sales was caused by the more significant decline
in revenues.

Research, development and engineering expenses

Research, development and engineering expenses decreased 29%, or $139 million in
2003 compared to 2002 and as a percentage  of sales  improved four points in the
same period.  The improvement  reflects the cost savings which resulted from the
2002  restructuring  actions.  Research,  development and  engineering  expenses
declined  22%, or $139 million in 2002  compared to 2001. As a percentage of net
sales,  RD&E  increased  five points from 2001. The decrease in expense for 2002
reflects  the  impact of the  restructuring  actions,  while the  increase  as a
percentage of net sales was caused by the more significant decline in revenues.

Restructuring, impairment and other charges and credits



Corning recorded significant net charges in 2003, 2002 and 2001. These charges are summarized in the following table (in millions):

     Impairment of Goodwill

     2003 Annual Assessment

     Due to  market  conditions  in  the  telecommunications  and  semiconductor
     industries,    we   performed    goodwill    impairment   tests   for   our
     Telecommunications  and specialty  materials  reporting units in the fourth
     quarter of 2003.  The results of our  impairment  tests  indicated that the
     fair value of each  reporting  unit  exceeded  its book value.  Although an
     impairment  charge was not  required in 2003,  it is  possible  that future
     impairment  charges  may be  required  if our  expected  future  cash  flow
     estimates are not realized.  Management must exercise judgment in assessing
     the  recoverability  of goodwill.  See Critical  Accounting  Estimates  for
     related discussion.

     We believe the  telecommunication  industry is currently depressed but will
     ultimately  recover.  We do  not  expect  growth  in  this  segment  in the
     short-term,  but believe  that growth will return to this  segment by 2005.
     Our view that the industry will recover is based on the fact that bandwidth
     demand  continues  to grow,  and the belief  that a  combination  of public
     policy changes,  consolidation  and recovery of industry  players,  and the
     advancement of profitable  broadband business models will drive recovery in
     the future.

     We believe the specialty materials reporting unit decrease in sales in 2003
     was primarily due to the cyclical nature of the  semiconductor  market.  We
     expect increased volume growth beginning in 2004.





     2002 Charge

     In the fourth quarter of 2002, we conducted our annual impairment tests and
     concluded  that  an  impairment   charge  of  $400  million  ($294  million
     after-tax)  was  necessary to reduce the carrying  value of goodwill in the
     Telecommunications  reporting  unit to its  estimated  fair  value  of $1.6
     billion.  The decrease in fair value at the end of 2002 from that  measured
     in the initial benchmark  assessment on January 1, 2002 primarily reflected
     the following:

     .    a delay in the timing of the  expected  recovery  from late  2002,  or
          early 2003 to 2005,
     .    a reduction in the short-term cash flow  expectations of the fiber and
          cable business and a lower base from which the expected  recovery will
          occur, and
     .    a reduction in the short and long-term cash flow  expectations  of the
          photonic technologies product line.

     We  retained  valuation  specialists  to  assist  in the  valuation  of our
     tangible and identifiable  intangible assets for the purpose of determining
     the implied fair value of goodwill at December 31, 2002.

     2001 Charge

     During the first half of 2001, we experienced a significant decrease in the
     rate  of  growth  of  our  Telecommunications  segment,  primarily  in  the
     photonics   technologies   product  line  due  to  a  dramatic  decline  in
     infrastructure spending in the telecommunications  industry, and determined
     that there were events of impairment within  photonics.  We determined that
     our goodwill  related to photonics was not recoverable  under SFAS No. 121,
     "Accounting  for the  Impairment  of Long-Lived  Assets and for  Long-Lived
     Assets to Be Disposed  of," which was the governing  accounting  principles
     generally  accepted in the U.S.  (GAAP) guidance at that time. As a result,
     we  recorded a charge of $4.6  billion to impair a  significant  portion of
     goodwill, of which $3.0 billion related to the Pirelli transaction and $1.6
     billion  related to goodwill  resulting  from the  acquisition  of NetOptix
     Corporation.

     Restructuring Actions

     2003 Restructuring Actions

     Corning  recorded net charges of $49 million ($14 million  credit after tax
     and minority  interest) in 2003.  Major  actions  approved and initiated in
     2003 included the following:

     .    the  shutdown  of CAV,  which was a  manufacturer  of glass  panel and
          funnels for use in conventional tube televisions,
     .    the   sale   and   exit  of  our   photonics   products   within   the
          Telecommunications segment, and
     .    the  shutdown  of  two  of  our  specialty   materials   manufacturing
          facilities.

     Restructuring Charges
     ---------------------
     The 2003  restructuring  charges of $41  million  included  $90  million of
     employee  separation costs (including  special  termination and curtailment
     losses  related to pension  and  postretirement  health care plans) and $37
     million in other exit costs  (principally  lease  termination  and contract
     cancellation payments), offset by an $86 million credit related to previous
     restructuring  actions.  These credits were primarily the result of revised
     cost estimates of existing  restructuring  plans and a decision to not exit
     two  small  cabling  sites.   The  charge   entailed  the   elimination  of
     approximately  1,975 hourly and salaried  positions  including  involuntary
     separation,  early retirement and social programs. In addition, we recorded
     a  $20  million  foreign  deferred  tax  benefit   adjustment   related  to
     restructuring  charges  recorded in 2002.  This credit is  reflected in the
     consolidated statement of operations under, "Benefit for income taxes."

     Impairment of Plant and Equipment to be Shutdown or Disposed
     ------------------------------------------------------------
     Corning  recorded a net credit of $21 million in 2003.  This  included  $40
     million of charges to impair plant and  equipment  related to facilities to
     be  shutdown  or  disposed,  which  comprised  $11  million  for the  North
     Brookfield  semiconductor materials plant closure, $14 million related to a
     cabling plant,  $10 million related to the final exit of photonics,  and $5
     million of other various  costs.  The  impairment  charges were  determined
     based on the amount by which the  carrying  value  exceeded the fair market
     value of the  asset.  The  charge  was more than  offset by $61  million in
     credits  related to previous  restructuring  actions.  These  credits  were
     primarily  the  result  of our  decision  not to exit  two of the  previous
     cabling  sites  marked for  shutdown  in 2002 as well as  proceeds on asset
     disposals exceeding assumed salvage values.

     Impairment of Cost Investments
     ------------------------------
     In the first  quarter,  we  recorded  a $5  million  charge  for other than
     temporary  declines in certain cost  investments in the  Telecommunications
     segment.  In the third quarter, we sold these investments for $4 million in
     cash, which was $1 million more than previously expected.  We reported this
     gain as a credit to restructuring actions.



     Loss on Sale of Photonics
     -------------------------
     We recorded a loss of $13 million in the third  quarter  when we  completed
     the sale of certain photonic technologies assets to Avanex. In exchange for
     our  photonics  assets and $22  million  in cash,  we  received  21 million
     restricted shares of Avanex common stock,  which we valued at approximately
     $53 million.  These shares are restricted from sale for  approximately  one
     year at which point the restrictions are lifted at intervals beginning July
     2004 and ending  October 2005. As the shares become  unrestricted,  we will
     mark-to-market   the  shares   through   other   comprehensive   income  as
     available-for-sale  securities.  The Avanex restricted shares are reflected
     as a cost investment and recorded under  "Investments"  in our consolidated
     balance  sheet.  Approximately  400 employees of the photonic  technologies
     products became employees of Avanex in the third quarter.  The loss on sale
     included  a  $21  million   reduction   of  our   goodwill.   See  Notes  5
     (Restructuring  Actions) and 10 (Investments) of the Consolidated Financial
     Statements for further detail.

     In addition to these  restructuring  action  costs,  we also  incurred  the
     following  charges in our consolidated  statement of operations  related to
     the exit of photonics:

     .    an increase to the deferred tax valuation  allowance by $21 million as
          we do not  expect to  realize  certain  deferred  tax assets in Italy,
          which is reflected in the consolidated  statement of operations under,
          "Benefit for income taxes," and
     .    a $7  million  impairment  charge  for  equity  investments  that were
          abandoned  as part of the exit from  photonics,  which is reflected in
          the consolidated statement of operations under, "Equity in earnings of
          associated companies, net of impairments."

     Accelerated Depreciation
     ------------------------
     We recorded  $12  million of  accelerated  depreciation  as a result of our
     decision to shutdown our semiconductor  materials manufacturing facility in
     Charleston,  South Carolina by March 31, 2004. We will record an additional
     $36  million  in the  first  quarter  of 2004  while  the  plant  continues
     operating.

     Cash payments for employee-related costs will be substantially completed by

     restructuring charges to be paid in cash.

     -------------------------------------------------------------------------------------------------------------------------------


     As of December 31, 2003,  approximately  1,600 of the 1,975  employees  had
     been  separated  under  the 2003  plans.  We  expect  the  remaining  to be
     separated by December  31,  2004,  with the majority to be separated by the
     end of the first quarter of 2004.

     2002 Restructuring Actions

     The continued  decline in demand in the  Telecommunications  segment during
     2002 required additional  restructuring  beyond that taken in 2001 to bring
     manufacturing capacity in line with revenue projections.  We recorded total
     charges of $1.3 billion ($929 million after-tax and minority interest) over
     the second,  third and fourth  quarters.  Actions approved and initiated in
     2002 included the following:

     .    permanent  closing of our optical  fiber  manufacturing  facilities in
          Noble Park, Victoria,  Australia, and Neustadt bei Coburg, Germany. We
          also mothballed our optical fiber  manufacturing  facility in Concord,
          North Carolina and transferred certain capabilities to our Wilmington,
          North Carolina facility,
     .    reductions in capacity and  employment in our cabling and hardware and
          equipment locations worldwide to reduce costs,
     .    permanent  closure  of our  photonic  technologies  thin  film  filter
          manufacturing facility in Marlborough, Massachusetts,
     .    permanent  abandonment of certain construction  projects that had been
          stopped  in  2001  in  the  fiber  and  cable   business   within  the
          Telecommunications segment,
     .    closure  of  minor   manufacturing   facilities,   primarily   in  the
          Telecommunications segment,
     .    closure and consolidation of research facilities,
     .    elimination of positions  worldwide  through voluntary and involuntary
          programs, and
     .    divestiture of a portion of the controls and  connectors  product line
          in the Telecommunications segment.

     In  addition,  we impaired  cost based  investments  in a number of private
     telecommunications companies based upon a decision in the fourth quarter of
     2002 to divest the portfolio.

     2001 Restructuring Actions

     In July and October of 2001, we announced a series of restructuring actions
     in response to significant  deteriorating  business  conditions which began
     initially in our  Telecommunications  segment, but eventually spread to our
     other  businesses  as the  year  progressed.  The  following  actions  were
     approved and undertaken in 2001:

     .    closure of seven major manufacturing  facilities and the consolidation
          of several smaller facilities in the  Telecommunications  segment,  as
          well as the lighting and conventional television businesses,
     .    discontinuation  of our  initiative in Corning  Microarray  Technology
          products, part of our Life Sciences segment, and
     .    elimination of approximately  12,000 positions affecting all operating
          segments, but especially impacting the photonic technologies, hardware
          and equipment and the optical  fiber and cable  products.  This action
          included a selective  voluntary early  retirement  program for certain
          employees along with involuntary separations.

     These  actions  resulted in a pre-tax  charge  totaling  $953 million ($585
     million after-tax) for the year ended December 31, 2001.  Approximately one
     third of the total charge was expected to be paid in cash.

     Impairment Of Long-Lived Assets Other Than Goodwill

     Given our  restructuring  actions  and the  market  conditions  facing  our
     businesses,  at  various  times  throughout  2001  to  2003,  we  performed
     evaluations of the  recoverability  of our long-lived  assets. In each case
     that an impairment  evaluation  was required,  we developed  operating cash
     flow projections for each strategic  alternative and made assessments as to
     the probability of each outcome. If our projections indicated that our long
     lived assets were not  recoverable  through future cash flows, we were then
     required to estimate the fair value of the  long-lived  assets,  which were
     limited to property,  plant and  equipment,  using the  expected  cash flow
     approach as a measure of fair value.

     2003 Impairment Charge

     In April 2003, we announced that we had agreed with our partner to shutdown
     CAV and wrote  down its  assets to their  estimated  salvage  values.  This
     resulted in an impairment  charge of $62 million ($19 million after-tax and
     minority interest).

     Subsequent  to our decision to exit,  CAV signed a definitive  agreement to
     sell tangible assets to Henan Anyang CPT Glass Bulb Group, Electronic Glass
     Co., Ltd. (Henan Anyang), located in China, for amounts exceeding estimated
     salvage values. Upon the receipt of $10 million in cash, we recognized a $5
     million credit in restructuring.  We expect the sale to be completed in the
     first half of 2004 at which time we  anticipate  recognizing  an additional
     gain of  approximately  $40 million  ($13  million  after-tax  and minority
     interest).






     2002 Impairment Charges

     Photonic technologies
     ---------------------
     In 2002,  the  telecommunications  market  underwent a dramatic  decline in
     demand  for its  products  as major  buyers of  network  equipment  in this
     industry reduced their capital  spending.  This negative trend was expected
     to continue  into the  foreseeable  future.  As a result of our  impairment
     evaluation,  the  photonics  assets were written down to estimated  salvage
     value, as this amount was our best estimate of fair value. This resulted in
     a $269 million ($195 million after-tax) write down of the long-lived assets
     including $90 million related to patents.

     Conventional video components
     -----------------------------
     In 2002,  the market was  impacted by a decline in demand for  conventional
     television  glass and a dramatic  increase in the importation of television
     glass,  tubes and sets from Asia.  These  trends were  expected to continue
     into the  foreseeable  future.  As a result of our  impairment  evaluation,
     CAV's  assets  were  written  down to their  estimated  fair  values.  This
     resulted in a $140 million ($44 million  after-tax  and minority  interest)
     write-down of the assets.

     2001 Impairment Charges

     Photonic technologies
     ---------------------
     In  2001,  the  telecommunications  market's  dramatic  decline  began.  We
     performed an asset impairment  evaluation of our photonics product line and
     incurred a charge of $116 million to write down intangible  assets to their
     estimated fair values.

Asbestos settlement

On  March  28,  2003,  we  announced  that we had  reached  agreement  with  the
representatives  of asbestos  claimants  for the  settlement  of all current and
future  non-premises  asbestos claims against us and PCC, which might arise from
PCC products or operations.

The agreement is expected to be incorporated into a settlement fund as part of a
reorganization  plan  for  PCC.  The  plan  will  be  submitted  to the  federal
bankruptcy  court in  Pittsburgh  for  approval,  and is  subject to a number of
contingencies,  including  a  favorable  vote by 75% of the  asbestos  claimants
voting on the PCC  reorganization  plan. We will make our  contributions  to the
settlement  trust  under  the  agreement  after  the plan is  approved,  becomes
effective and is no longer subject to appeal.  We expect the approval process to
be complete in 2004.

When the plan becomes effective, our settlement will require the contribution of
our equity  interest in PCC, our one-half equity interest in PCE, and 25 million
shares of our common  stock.  The common  stock  will be  marked-to-market  each
quarter until it is  contributed  to the  settlement  trust,  thus  resulting in
adjustments to income and the settlement liability as appropriate.  We will also
make cash payments with a current value of $136 million over six years beginning
in June 2005 which we will  accelerate,  as needed,  to maximize the related tax
benefits. In addition, we will assign insurance policy proceeds from our primary
insurance and a portion of our excess  insurance as part of the  settlement.  We
recorded  an  initial  charge of $298  million  in the first  quarter of 2003 to
reflect the terms of the settlement  and  additional  charges of $115 million to
reflect the mark to market of our common stock through  December 31, 2003. Total
charges of $413 million  ($263 million  after-tax)  were incurred for the twelve
months  ended  December  31,  2003.  This  charge was  previously  reported as a
nonoperating  charge in our 2003 Quarterly Reports on Form 10-Q.  Effective with
the Annual  Report on Form 10-K as of December  31, 2003,  we have  reclassified
this charge to operating expenses in the consolidated  statements of operations.
The  carrying  value of our  investment  in PCE and the fair value of 25 million
shares of our common  stock,  totaling  $282  million,  have been  reflected  in
current  liabilities.  The remaining $136 million,  representing the net present
value of the cash  payments,  discounted  at 5.5%,  is  recorded  in  noncurrent
liabilities.  See Legal  Proceedings in our most recent quarterly report on Form
10-Q for a history of this matter.

Operating loss

We incurred an operating  loss of $655  million in 2003 which was  significantly
lower than the 2002 loss of $2.7  billion  and the 2001  operating  loss of $6.0
billion.  Our loss in 2003 included the asbestos settlement  charges.  Losses in
all three years included restructuring, impairment and other charges and credits
as  described  above.  Our results for 2001 were also  impacted by an  operating
charge of $333  million to  write-down  excess  and  obsolete  inventory,  a $90
million  charge  related  to the  release of  restrictions  on shares of Corning
common  stock  and  a  $28  million   charge  to  write-down  an  investment  in
intellectual property.







Gain on repurchases and retirement of debt, net

During the years ended December 31, 2003 and 2002, we repurchased  and retired a
significant  portion of our zero coupon  convertible  debentures due November 8,
2015. In 2003, we repurchased and retired 1,531,000  debentures with an accreted
value of $1.2 billion for cash of approximately $1.1 billion through open market
purchases and a public  tender offer and recorded a net gain of $55 million.  We
also issued 6.5 million  shares of common  stock from  treasury in exchange  for
55,000 debentures with an accreted value of $43 million, and recognized a charge
of $35 million reflecting the fair value of the incremental shares issued beyond
those required by the terms of the debentures. The increase in equity due to the
issuance of shares from treasury stock was $77 million.

convertible debentures (dollars in millions):

euros (including accrued interest) or $70 million. We recorded a loss of $1
million on the transaction.

--------------------------------------------------------------------------------

Our effective tax rate was impacted by our  restructuring,  impairment and other
charges  and  credits  and our gains on  repurchases  and  retirements  of debt.
Excluding  these items,  our rate was (33)% in 2003,  (30)% in 2002 and (13)% in
2001.

SFAS No.109,  "Accounting  for Income Taxes ("SFAS No.  109"),"  requires that a
valuation allowance be established when it is more likely than not that all or a
portion of a deferred tax asset will not be realized.  A review of all available
positive and negative  evidence  needs to be  considered,  including a company's
current,  past and future predicted  performance,  the market environment of the
industries in which the company  operates,  the utilization of past tax credits,
length of carryback and carryforward  periods,  and existing  contracts or sales
backlog that will result in future profits.

At  December  31,  2003,  we  have  recorded   gross   deferred  tax  assets  of
approximately  $2.1 billion  with a valuation  allowance  of $469  million,  and
offset by deferred tax liabilities of $201 million.  The valuation  allowance is
primarily  attributable to the uncertainty regarding the realization of specific
foreign and state tax benefits,  net operating  losses and tax credits.  The net
deferred tax assets of  approximately  $1.5 billion  consist of a combination of
domestic (U.S. federal, state and local) and foreign tax benefits for: (a) items
which have been recognized for financial reporting  purposes,  but which will be
reported on tax  returns to be filed in the future,  and (b) loss and tax credit
carryforwards.  As  explained  further  below,  we have  performed  the required
assessment of positive and negative  evidence  regarding the  realization of the
net  deferred  tax  assets in  accordance  with SFAS No.  109.  This  assessment
included  the  evaluation  of scheduled  reversals of deferred tax  liabilities,
estimates  of  projected  future  taxable  income and  tax-planning  strategies.
Although realization is not assured, based on our assessment,  we have concluded
that it is more likely than not that such assets,  net of the existing valuation
allowance, will be realized.





Net domestic deferred tax assets are approximately  $1.3 billion at December 31,
2003. Approximately $460 million of these net deferred tax assets relate to loss
and tax credit  carryforwards  that  expire  through  2023.  The  remaining  net
deferred tax assets comprise the following deductible temporary differences:

1.   other postretirement  benefits of $244 million, which will reverse over the
     next 40 to 50 years;
2.   restructuring  and other  liabilities  of $155 million,  which will reverse
     over the next 10 years;
3.   research and development  expenditures of $252 million,  which will reverse
     over the next 10 years; and
4.   other miscellaneous items of $178 million,  which will reverse, on average,
     over the next 10 years.

Approximately  10% of our net  domestic  deferred  tax assets  will be  realized
through net operating loss  carryback  claims to be filed over the next three to
five years,  which will generate cash refunds during such period.  We expect the
remaining net domestic  deferred tax assets to be realized from future earnings.
However, in the event future earnings are insufficient, approximately 40% of our
net  domestic  deferred  tax assets  could be  realized  through a  tax-planning
strategy involving the sale of a non-strategic appreciated asset. Realization of
the remaining 50% of our net domestic deferred tax assets is solely dependent on
our ability to generate  sufficient  future taxable  income during  carryforward
periods of approximately 20 years.

The minimum amount of domestic  future income that would have to be generated to
realize this portion of our deferred tax assets is $1.7 billion over at least 20
years.  Currently,  we are generating domestic losses.  However, our forecast of
domestic income  indicates it is more likely than not that the future results of
operations in the U.S. will generate  sufficient  taxable income to realize this
portion  of  our  deferred  tax  assets.   Specifically,   we  expect  to  incur
significantly  lower domestic losses in 2004 and to return to  profitability  in
the U.S. in 2005. Key assumptions embedded in these near-term forecasts follow:

1.   Our 2004  U.S.  losses  will  decrease  as a result of the 2003 exit of the
     photonics technologies business and CAV.
2.   We expect to see improved earnings trends in our Telecommunications segment
     which is  primarily  in the U.S.  This  includes a lower loss in 2004 and a
     return to  profitability  in 2005.  This trend is partially being driven by
     the  realization  of lower  operating  costs as a  result  of prior  years'
     restructuring  actions. In addition,  we are forecasting revenue to be flat
     or down  slightly  in  2004  but  significantly  higher  in 2005  due to an
     expected recovery in the telecommunications industry in 2005.
3.   Our  specialty  materials   semiconductor  business  will  generate  higher
     earnings in 2004 as a result of a recovery in the  semiconductor  equipment
     industry and lower  operating  costs as a result of the fourth quarter 2003
     restructuring  actions,  which  will be  completed  by the end of the first
     quarter of 2004.
4.   Our Display Technologies  segment will continue its rapid growth.  Although
     this business is largely based in Asia,  domestic earnings of this business
     have  increased in 2003 and are  expected to continue to increase  over the
     next several years, in part due to an increase in U.S. royalty income.
5.   We will  continue  to  sustain  modest  growth  in our  remaining  domestic
     businesses and,  except for the  restructuring  actions  announced prior to
     December 31,  2003,  we do not expect to incur any  significant  additional
     restructuring or impairment charges.

Our forecast of domestic income is based on assumptions about and current trends
in our operating segments,  and there can be no assurance that such results will
be achieved.  We review such  forecasts in  comparison  with actual  results and
expected trends  quarterly for purpose of our  recoverability  assessment.  As a
result of this review,  if we determine that we will not return to profitability
in the U.S. in 2005 or if sufficient  future taxable income may not be generated
to fully  realize the net deferred tax assets,  we will  increase the  valuation
allowance by a charge to income tax expense in an amount equal to the portion of
the deferred tax assets that are  realizable  solely  through  projected  future
taxable income. If we record such a valuation  allowance,  we will also cease to
recognize additional tax benefits on any losses in the U.S.

Equity in earnings of associated companies, net of impairments

Equity  earnings nearly doubled to $209 million in 2003. The increase was due to
the following:

..    The resumption of the  recognition  of equity  earnings from Dow Corning in
     2003  added $82  million  to equity  earnings  in 2003.  In 1995,  we fully
     impaired  our  investment  in Dow  Corning  upon its entry into  bankruptcy
     proceedings  and did not recognize  equity earnings from the second quarter
     of 1995 through the end of 2002. We began  recognizing  equity  earnings in
     the first quarter of 2003 when we concluded  that Dow  Corning's  emergence
     from  bankruptcy  protection was probable  based on the Bankruptcy  Court's
     findings on December 11, 2002. See Legal  Proceedings for a history of this
     matter.

..    Our 50% owned Samsung  Corning  Precision,  a South Korean  manufacturer of
     liquid crystal  display glass,  increased its net income by 82% compared to
     2002,  resulting in equity earnings $64 million higher than 2002.  Earnings
     in 2003 were $144 million.

..    These positive results were negatively  impacted by Samsung Corning,  which
     recorded a significant  asset  impairment  charge in the fourth  quarter of
     2003.  Our  portion  of that  charge  was $66  million  (after-tax),  which
     resulted in a net equity loss of $39 million.



Equity earnings in 2002 were $116 million, a decline of 22% from 2001, primarily
due to the impairment of an equity  investment in the second quarter of 2002 for
$14  million  and a $20  million  reduction  in equity  earnings  in the  fourth
quarter,  caused by  restructuring  and impairment  charges  recorded by Samsung
Corning  Micro  Optics,  a  50%  owned  manufacturer  of  photonics  components.
Excluding these items, equity earnings approximated those in 2001.

RESULTS OF DISCONTINUED OPERATIONS

On December 13, 2002, we completed the sale of our precision lens business to 3M
Company  (3M) for cash  proceeds  up to $850  million,  of which $50 million was
deposited in an escrow  account.  During 2002,  we received  approximately  $800
million in cash and recorded a gain on the sale of $415 million,  net of tax, in
income  from   discontinued   operations  in  the  consolidated   statements  of
operations.  3M has  notified  Corning  that 3M believes  it has certain  claims
arising out of the  representations and warranties made by Corning in connection
with the sale of the precision  lens business to 3M. The parties are  attempting
to resolve such claims.  In 2003,  $1 million of the escrow  balance was used to
pay state income taxes. At December 31, 2003,  approximately $49 million remains
in the  escrow  account,  and no other  gain on the sale of the  precision  lens
business will be recognized until such claims are resolved.

The precision lens business  operating  results and cash flows have been removed
from our results of continuing  operations for all periods  presented,  and have
been  excluded  from the  operating  segments  data.  There were no results from
discontinued operations in 2003.

OPERATING SEGMENTS

Effective  with the  first  quarter  of 2004,  we have  revised  our  reportable
operating    segments    from    Telecommunications    and    Technologies    to
Telecommunications,  Display Technologies,  Environmental Technologies, and Life
Sciences. The following provides a brief description of the products and markets
served by each reportable segment:

..    Telecommunications - manufactures optical fiber and cable, and hardware and
     equipment components for the worldwide telecommunications industry;
..    Display  Technologies - manufactures  liquid crystal display glass for flat
     panel displays;
..    Environmental  Technologies - manufactures  ceramic  substrates and filters
     for automobile and diesel applications; and
..    Life Sciences - manufactures  glass and plastic  consumables for scientific
     applications.

The change in our segment  presentation  reflects how Corning's  Chief Operating
Decision Making group ("CODM") allocates  resources and assesses the performance
of its businesses.  Specifically,  the CODM is increasing its level of review of
the Display  Technologies  segment  significantly  due to the recent increase in
growth and capital spending in that segment. In addition, the CODM is increasing
its review of the  Environmental  Technologies  and Life  Sciences  segments  to
strengthen  the  overall  balance  and  stability  of  Corning's   portfolio  of
businesses.



We prepared the financial results for our operating  segments on a basis that is
consistent  with  the  manner  in  which we  internally  disaggregate  financial
information to assist in making  internal  operating  decisions.  We include the
earnings of equity  affiliates  that are closely  associated  with our operating
segments in the  respective  segment's  net income.  We have  allocated  certain
common  expenses  among  segments  differently  than we  would  for  stand-alone
financial  information  prepared in accordance with GAAP. These expenses include
interest,  taxes  and  corporate  functions.  Segment  net  income  may  not  be
consistent with measures used by other companies. The accounting policies of our
operating  segments are the same as those applied in the consolidated  financial
statements.

     centralized  basis.  Where  practicable,  Corning charges these expenses to
     segments  based upon the extent to which each  business  uses a centralized
     function. Other staff functions, such as corporate finance, human resources
     and legal are allocated to segments, primarily as a percentage of sales.
(5)  Includes  an  allocation  of   depreciation   of  corporate   property  not
     specifically  identifiable to a segment. Related depreciable assets are not

Telecommunications

The  Telecommunications  segment  produces  optical fiber and cable, and optical
hardware and equipment for the worldwide  telecommunications  industry.  In July
2003, we exited the photonic technologies product line.

The following table provides net sales and other data for the Telecommunications
segment (in millions):

2003 vs. 2002

Sales in the segment  declined  13%,  or $205  million,  compared  to 2002.  All
products  in the segment  incurred a decline in sales.  A portion of the decline
was in photonic technologies which we exited in July 2003. The remaining decline
in sales was due to price  decreases  for  optical  fiber and cable  which  were
partially  offset by  volume  increases.  The  segment  incurred  a loss of $169
million in 2003, compared to a net loss of $1.9 billion in the prior year.



Restructuring and impairment  charges included a $13 million loss on the sale of
photonics  technologies  assets  to Avanex  and $88  million  for  restructuring
charges  offset by  credits of $137  million,  resulting  in net  credits of $36
million.  All of the  Telecommunications  products  reported  a  loss  in  2003;
however,  the losses were  significantly  lower than those incurred in the prior
year.  The  decrease in the loss over the prior year was  primarily  due to much
lower restructuring and impairment charges and cost savings resulting from these
actions.

The following discussion of products in the Telecommunications  segment excludes
the restructuring  and impairment  charges and credits to provide clarity on the
underlying business trends.

Optical fiber and cable
-----------------------
Sales declined 12%, or $99 million  compared to 2002. The decrease was primarily
due to pricing  pressure,  particularly  in fiber,  but was partially  offset by
strong demand in Japan and China,  primarily in the first quarter.  Sales volume
increased  almost 20% in 2003  compared to 2002 due primarily to having the full
year results of the Chinese fiber and cable entities acquired from Lucent in the
fourth quarter of 2002. Volumes for our other fiber and cable facilities were up
slightly in 2003 compared to 2002. The loss for 2003 was significantly less than
2002 due to significant cost reduction.

Hardware and equipment
----------------------
Sales  decreased  7%, or $49 million in 2003,  compared  to the prior year.  The
sales decrease was primarily due to the overall lack of capital  spending by our
customers impacting the entire telecommunications  industry, as well as the sale
of the appliance  controls  group in May 2002.  The loss for 2003  significantly
decreased  from the prior  year due to cost  reductions  achieved  from the 2002
restructuring actions and other cost reduction initiatives.

Photonic technologies
---------------------
On July 31, 2003, we completed the sale of a significant portion of the photonic
technologies  assets to Avanex. See Restructuring,  Impairment and Other Charges
and Credits and Note 5  (Restructuring  Actions) to the  Consolidated  Financial
Statements.  Sales  declined 51%, or $57 million,  compared to 2002 due to lower
sales  volume  in the  early  part of the year as well as our exit of  photonics
technologies  in 2003.  The loss in 2003 was more  than 85% less  than the prior
year loss due to cost savings resulting from restructuring actions taken in 2002
as well as the exit of this business in 2003.

2002 vs. 2001

This segment incurred  significant  restructuring and impairment charges in 2002
and 2001.  The 2002 and 2001 charges are  described in detail in  Restructuring,
Impairment  and Other Charges and Credits.  The  restructuring  activities  were
undertaken  to reduce the  operating  cost  structure  due to  continued  market
declines.  More than half of the 2002 charge  related to the impairment of fixed
assets,  primarily in the fiber and cable business. A significant portion of the
asset  impairments in this business  represented the closure of two fiber plants
and permanent abandonment of certain construction  projects.  The balance of the
charge  represented  impairments  of cost based  investments,  primarily  in the
photonic  technologies  business,  and  severance  and benefits for retirees and
separated personnel in all businesses.  In addition, the segment incurred a $400
million  charge for the  impairment  of goodwill and a $269  million  charge for
long-lived asset  impairments in photonic  technologies.  The impairment  charge
incurred in the second quarter of 2001 relates to goodwill and certain  acquired
intangible assets from acquisitions in the photonic technologies business. These
charges are described in Notes 4 (Impairment  of Goodwill) and 6 (Impairment  of
Other Long-Lived Assets) to the Consolidated Financial Statements.

Sales in the segment  declined 63%, or $2,827 million,  compared to 2001 as each
product in the  segment  experienced  a  significant  decline in volume with the
largest  declines  in optical  fiber and cable and  photonic  technologies.  The
segment incurred losses of $1.9 billion in 2002,  compared to a net loss of $5.2
billion in 2001. The 2002 loss was primarily due to the significant  decrease in
sales  volume and  restructuring  and  impairment  charges.  Each  product  line
reported a loss in 2002. The trend between years reflected  lower  restructuring
and impairment  charges.  Excluding these  restructuring and impairment charges,
the segment net loss was $592 million compared to a loss of $81 million in 2001.
The  increase  in the loss in 2002  reflected  reduced  sales  volumes and lower
prices  in  each  product  line  offset  by  cost   reductions   resulting  from
restructuring actions.

The following discussion of products in the Telecommunications  segment excludes
the restructuring  and impairment  charges and credits to provide clarity on the
underlying business trends.

Optical fiber and cable
-----------------------
Sales  declined  70%, or $2,030  million  compared  to 2001.  The  decrease  was
primarily due to a sales volume decline of more than 50% for the year as well as
double digit price declines. Excluding restructuring and impairment charges, the
optical  fiber and cable  product  line  incurred  a  significant  loss in 2002,
compared  to profits in the prior year,  primarily  due to  significantly  lower
sales volume, declining prices and unfavorable product mix.






As discussed in Restructuring  Actions, the optical fiber and cable product line
undertook significant restructuring actions in the fourth quarter of 2002. These
actions included  permanent  closure of two  international  fiber  manufacturing
plants and the mothballing of the Concord,  North Carolina facility.  We believe
that the Concord  facility can be returned to productive  capacity within six to
nine months of a decision to do so and  construction  in progress at the Concord
facility can be  completed  efficiently.  We believe the Concord and  Wilmington
plants will provide sufficient capacity for the foreseeable future.

Hardware and equipment
----------------------
Sales decreased 35%, or $361 million, compared to 2001. The sales decreases were
primarily   due  to  the  overall   lack  of  spending   impacting   the  entire
telecommunications industry, as well as the sale of the appliance controls group
in May 2002. Excluding  restructuring  charges, the product line incurred a loss
driven  by lower  volumes  and  pricing  pressure  in 2002,  compared  to a near
breakeven performance in 2001.

Photonic technologies
---------------------
Sales  declined 80%, or $436 million,  compared to 2001,  primarily due to lower
sales volume as network build-outs in the  telecommunications  industry declined
resulting in much lower demand for photonic  products.  The business  incurred a
significant  loss for 2002  primarily due to  dramatically  lower sales volumes.
However,  the 2002  losses  decreased  more than  50%,  compared  to the  losses
incurred in 2001,  which included  inventory  write-downs  of $333 million.  The
results in 2002 reflected cost reductions  resulting from restructuring  actions
taken in 2001 and 2002.

During the second quarter of 2002, we favorably  resolved an open issue from the
second quarter of 2001 with a major  customer,  resulting in the  recognition of
revenue of $14  million  and  pre-tax  income of $3  million.  This  revenue was
recognized in part on shipment of inventory previously reserved. In addition, we
settled  an open  matter  with a  significant  vendor in 2002  resulting  in the
reversal  of a vendor  reserve of $20 million  that was  recorded as part of the
charge in the second quarter of 2001.

Outlook:
The global  telecommunications market downturn that began in 2001 continued into
2003; however, we believe that conditions have begun to stabilize. We ultimately
expect a recovery in 2005,  and we believe 2004 will be  comparable  to 2003. We
expect  2004 sales to be flat to down  slightly  compared  to 2003.  Although we
expect  to see  volumes  in our  hardware  and  equipment  and  fiber  and cable
businesses to increase, we will continue to experience pricing pressure,  but at
a lower  level than in 2003.  We expect a loss in 2004;  however,  we believe it
will be significantly less than 2003,  primarily due to the exit of the photonic
technologies  product line and lower operating expenses  reflecting cost savings
from restructuring actions taken in 2003 and 2002.

Display Technologies

--------------------------------------------------------------------------------

2003 vs. 2002

Sales  increased  47%, or $190  million,  compared  to 2002.  The  increase  was
primarily due to volume gains of  approximately  43%, as  penetration  of liquid
crystal display panels in the desktop market increased,  and favorable  exchange
rates. Earnings  approximately doubled in 2003 compared to the prior year due to
the increase in volume and  significant  gains in equity  earnings  from Samsung
Corning Precision over the prior year.

In July 2003,  we  announced  a $180  million  expansion  of our liquid  crystal
display glass  manufacturing  facility in Taiwan.  The  three-phased  project is
expected  to be  completed  by the end of 2004 with  production  to begin in the
second quarter of 2004. In February 2004, we announced a $600 million  expansion
of our  liquid  crystal  display  glass  manufacturing  facilities  in Japan and
Taiwan. This expansion will occur over 2004 and 2005.






2002 vs. 2001

Sales  increased  25%,  or $82  million,  compared  to 2001.  The  increase  was
primarily  due to higher  sales  volume as  penetration  in the  desktop  market
increased.  The prior  year's  sales were  negatively  impacted by an  inventory
correction  in the industry in the first  quarter of 2001.  Volume gains of over
46% for 2002  were  partially  offset  by price  declines  of 10% on a  constant
currency basis.  Earnings increased 35% in 2002, compared to 2001, primarily due
to volume gains and a more than 30%  improvement in equity earnings from Samsung
Corning Precision.

Outlook:
We expect sales volume to increase in 2004, and weighted  average  pricing to be
stable. We also expect profitability in the segment to improve  significantly in
2004 due to the strong volume growth and increased  equity earnings from Samsung
Corning Precision.

Environmental Technologies

--------------------------------------------------------------------------------

2003 vs. 2002

Sales increased 21%, or $82 million,  compared to 2002. The increased sales were
primarily due to increased U.S. auto production driven by financing  incentives,
favorable mix of premium products, favorable exchange rates and higher sales for
diesel  products.  Earnings  decreased  72%  compared to the prior year due to a
decrease in equity earnings from Cormetech,  a U.S. designer and manufacturer of
industrial  catalysts,  and higher  development  spending for the diesel product
line.

2002 vs. 2001

Sales increased 4%, or $15 million, compared to 2001, primarily due to increased
U.S. auto production driven by financing  incentives and strong growth in Europe
and Japan.  Earnings improved 7%, compared to 2001, as a significant increase in
equity earnings from Cormetech,  a U.S.  designer and manufacturer of industrial
catalysts,  was partially  offset by price declines and increased  manufacturing
and development costs related to new products.

Outlook:
We expect  sales to increase  in 2004,  primarily  due to strong  demand for our
thin-wall automotive substrates and diesel products.

Life Sciences

Net income (loss)             $     14         $      25         $    (17)
--------------------------------------------------------------------------------

2003 vs. 2002

Sales were flat in 2003, compared to 2002, primarily due to weak sales in Europe
and a general  softness in the market.  Earnings  were down 44%  compared to the
prior year. Improved manufacturing  efficiencies,  and a gain on the disposition
of a minor product line, were more than offset by higher development spending.

2002 vs. 2001

Sales  increased 5%, or $13 million,  compared to 2001,  primarily due to strong
growth in most product lines.  The segment  returned to  profitability  in 2002,
primarily  due to cost savings from the  discontinuation  of our  investment  in
microarray technology products in the third quarter of 2001, as well as improved
manufacturing efficiencies and higher sales.






Outlook:
We expect  sales to  increase in 2004,  primarily  due to  stabilization  of the
market.

LIQUIDITY AND CAPITAL RESOURCES

Financing Structure

In 2003, we completed two equity offerings of our common stock as follows:

..    45 million shares in July for net proceeds of $363 million, and
..    50 million shares in May for net proceeds of $267 million.

We used the net proceeds of the May  offering and $356 million of existing  cash
to reduce debt through a public tender offer  conducted in June. We used the net
proceeds of the July  offering to reduce debt through  open market  repurchases.
See Note 17 (Shareholders' Equity) to the Consolidated Financial Statements.

We repurchased  and retired  approximately  1.6 million zero coupon  convertible
debentures in 2003 for approximately $1.1 billion in cash and 6.5 million shares
of treasury common stock.  See Note 14 (Long-Term Debt and Loans Payable) to the
Consolidated Financial Statements for further detail.

As a result of our debt  repurchase  program,  we  reduced  the  balance of zero
coupon convertible debentures as follows:
--------------------------------------------------------------------------------
                         December 31, 2003  December 31, 2002  December 31, 2001
--------------------------------------------------------------------------------

Zero coupon convertibles     $     385          $   1,606          $  2,059
--------------------------------------------------------------------------------

The remaining zero coupon  convertible  debentures will likely be put back to us
on  November  8, 2005,  at $819.54 per  debenture  and on  November 8, 2010,  at
$905.29 per debenture.  We have the option of settling this  obligation in cash,
common  stock,  or a  combination  of both.  From  time to time,  we may  retire
additional debt securities for cash or equity.

Due to our  debt  ratings,  we  continue  to be  precluded  from  accessing  the
short-term  commercial paper market.  The terms that we could receive on any new
long-term debt issues would likely be consistent with those generally  available
to high-yield issuers.

As an additional source of funds, we currently have full unrestricted  access to
a $2 billion  revolving  credit  facility with 17 banks,  expiring on August 17,
2005.  As of  December  31,  2003,  there  were no  borrowings  under the credit
facility.  The facility  includes one financial  covenant  limiting the ratio of
total debt to total  capital,  as defined,  to not greater than 60%. At December
31, 2003 and December 31, 2002, this ratio was 34% and 47%, respectively.



In March 2001, we filed a universal  shelf  registration  statement with the SEC
that  became  effective  in the first  quarter of 2001.  The shelf  permits  the
issuance of up to $5 billion of various debt and equity securities.  As of March
1, 2004,  our  remaining  capacity  under the shelf  registration  statement was
approximately $2.9 billion.

Subsequent Event

Through  March 1, 2004,  we  repurchased  and  retired 25  thousand  zero coupon
convertible  debentures for approximately $19 million in cash resulting in a net
decrease of $20 million to the zero coupon convertible  debenture book value. In
addition, we issued 22 million shares of Corning common stock and $24 million in
cash in  exchange  for 3.5%  convertible  debentures  with a book  value of $213
million at an  effective  conversion  price of $9.675 per share.  As a result of
these transactions, we will record a $23 million pre-tax loss on repurchases and
retirement of debt during the first quarter of 2004.

Capital Spending

Capital  spending  totaled $366 million,  $357 million and $1.7 billion in 2003,
2002 and  2001,  respectively.  Based on events  as of June 30,  2004,  our 2004
capital  spending  program is expected to be in the range of $950  million to $1
billion,  of which $750  million to $800  million will be to expand the capacity
for liquid crystal  display glass.  Capital  spending  activity in 2002 and 2003
primarily included expansion of liquid crystal display capacity and new capacity
for  diesel  substrates.  Capital  spending  in 2001  related  primarily  to the
Telecommunications segment.

Restructuring

During 2003,  2002 and 2001, we made payments of $233 million,  $278 million and
$77 million,  respectively,  related to employee  severance and other exit costs
resulting from restructuring  actions. Cash payments for employee-related  costs
and other exit costs will be  substantially  completed by the end of 2004, while
payments for exit activities will be substantially completed by the end of 2005.

Key Balance Sheet Data

At December 31, 2003, cash, cash equivalents and short-term  investments totaled
$1.3 billion, compared with $2.1 billion at December 31, 2002. The decrease from
December 31, 2002, was primarily due to long-term debt repayments, restructuring
payments, capital expenditures and the use for working capital. These items were
partially  offset by the proceeds from the May and July equity offerings and the
receipt of a U.S. federal tax refund of $191 million.

--------------------------------------------------------------------------------

Our 2003  earnings  were not  adequate to cover our fixed  charges  (principally
interest  and related  charges on debt),  primarily  as a result of the asbestos
settlement  charge,  losses  incurred  in  the  Telecommunications  segment  and
restructuring and impairment charges. We expect our full year 2004 earnings will
be sufficient to cover our fixed charges.

Management Assessment of Liquidity

Our major source of funding for 2004 and beyond will be our existing  balance of
cash, cash equivalents and short-term investments. From time to time we may also
issue debt or equity  securities to raise  additional  cash to fund a portion of
our capital  expenditures  related to our growth businesses.  We believe we have
sufficient   liquidity   for  the  next  several   years  to  fund   operations,
restructuring,  the  asbestos  settlement,  research  and  development,  capital
expenditures and scheduled debt repayments. We may accelerate some or all of the
funding of the cash payments to the asbestos  settlement  trust,  as needed,  to
maximize  the tax  benefits  we can  realize  in  connection  with  the  related
settlement charges.

Off Balance Sheet Arrangements

We have two variable  interest entities ("VIEs") that are not consolidated as we
are not the primarily  beneficiary.  The assets and debt of these entities total
$12 million. Our maximum loss exposure as a result of our involvement with these
VIEs is approximately $18 million. This amount represents payments that would be
due to the lessor in the event of a total loss of the assets. We carry insurance
coverage for this risk.

We have provided other financial  guarantees and have contingent  liabilities in
the form of purchase price  adjustments for  acquisitions,  stand-by  letters of
credit  and  performance  bonds,  some of which do not have  fixed or  scheduled
expiration  dates.  We have agreed to provide a credit  facility  related to Dow
Corning as  discussed in Note 10  (Investments)  to the  Consolidated  Financial
Statements.  The funding of the Dow Corning credit facility is subject to events
connected to the Bankruptcy  Plan. We believe the significant  majority of these
guarantees and contingent liabilities will expire without being funded.



In January 2003, the SEC released FR-67,  "Disclosure in Management's Discussion
and Analysis about  Off-Balance  Sheet  Arrangements  and Aggregate  Contractual
Obligations".  In response to this  guidance,  we have assessed our  off-balance
sheet and  contractual  obligations  and have  determined  that in  addition  to
previously  disclosed  items,  purchase  obligations  would be added.  Given the
nature of purchase  obligations,  we limited our assessment to individual  items
outstanding at December 31, 2003 greater than $1 million.

Pensions

We have a number of 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,  2003,  this plan  accounted  for 82% of our
consolidated defined benefit pension plans' projected benefit obligation and 89%
of the related  plans'  assets.  In 2002,  global  capital  market  developments
resulted in negative  returns on plan assets and a decline in the discount  rate
used to  estimate  the  related  pension  liability.  In 2003,  although  global
equities had positive returns, interest rates continued to decline. As a result,
at December 31, 2003 and 2002, the accumulated  benefit obligation (ABO) for our
domestic  qualified  and  non-qualified  plans and several  international  plans
exceeded the fair value of related plan assets, which required Corning to record
an  additional  minimum  pension  liability  in  accordance  with  SFAS No.  87,
"Employers' Accounting for Pensions."

We have  traditionally  contributed  to the U.S.  qualified  pension  plan on an
annual  basis  in  excess  of the IRS  minimum  requirements,  and as a  result,
mandatory  contributions  are not expected to be required for this plan at least
until 2006. We  contributed  $160 million in 2003 to our U.S.  pension plan. For
2004, we anticipate  making  voluntary  contributions of at least $40 million to
this plan.


CRITICAL ACCOUNTING POLICIES AND 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 follow.

Impairment of goodwill

SFAS No.  142,  "Goodwill  and Other  Intangible  Assets,"  requires  us to make
certain  difficult,  subjective  and complex  judgments  on a number of matters,
including  assumptions  and  estimates  used to determine  the fair value of our
reporting units and the definition of our reporting units.

We measure fair value on the basis of discounted expected future cash flows. Our
estimates are based upon our historical  experience,  our current knowledge from
our commercial  relationships,  and available external  information about future
trends.

The criteria for  establishing  a reporting unit is dependent upon how a company
determines  its  operating  segments  under  SFAS No.  131,  "Disclosures  about
Segments of an Enterprise and Related Information."  Specifically,  SFAS No. 142
permits a company to define a reporting unit as either an operating  segment,  a
component of an operating segment or an aggregation of two or more components of
an operating segment.  Our reporting units include  Telecommunications,  Display
Technologies,  Environmental Technologies,  Life Sciences,  specialty materials,
conventional  video  components,  and  ophthalmic.  At December  31,  2003,  the
Telecommunications,   specialty  materials  and  Display  Technologies  goodwill
balances were $1.6 billion, $150 million, and $9 million, respectively.

During 2002, we completed our annual goodwill  impairment  test,  determined the
Telecommunications  goodwill  balance  was  impaired,  and  recorded  a  related
impairment charge of $400 million. Our 2002 testing results also determined that
the  goodwill  was not  impaired  for any other  reporting  unit.  In the fourth
quarter  of  2003,  we  completed  our  annual  goodwill  impairment  tests  and
determined  that the goodwill  balances were not impaired.  As discussed in more
detail below,  while we believe the  estimates  and judgments  about future cash
flows used in the goodwill  impairment  tests are reasonable,  we cannot provide
assurance  that future  impairment  charges will not be required if the expected
cash flow estimates as projected by management do not occur.






Telecommunications

Our  expectation  is that there will be minimal volume growth in the short term;
volume  growth is assumed to  accelerate  beginning  in 2005  commensurate  with
overall  market  recovery.  Terminal  value of the business  assumes a growth in
perpetuity  of 3%.  These  cash  flows  are also  used to value  intangible  and
tangible  assets which  determine the implied value of reporting  unit goodwill.
The discount  rate applied to these cash flows  represents a  telecommunications
weighted  average cost of capital based upon current debt and equity activity of
eleven public companies representing a cross section of worldwide competitors of
the reporting  unit. For our 2002 annual test, we used a discount rate of 12% in
our  calculation of fair value of the expected  future cash flows. An impairment
charge of $400  million  was  recorded in 2002.  Had we used a discount  rate of
11.5%,  the fair value of the  reporting  unit would have  exceeded its carrying
value, and there would not have been impairment.  Had we used a discount rate of
12.5%, the pre-tax  impairment charge would have been approximately $225 million
higher.  In 2003,  we also used a 12%  discount  rate for our annual  impairment
test.  The results of our test  indicated  that goodwill was not  impaired.  The
results would not have changed had we used a discount rate of 11.5% or 12.5%.

Specialty materials

Due to market conditions,  we determined that a detailed  impairment test of the
specialty  materials  reporting unit was required in the fourth quarter of 2003.
While there was a significant  decrease in sales in 2003 in this  reporting unit
due to the cyclicality of the semiconductor industry, we expect increased volume
growth  beginning in 2004. Our discounted cash flow test for this reporting unit
assumes a  perpetuity  growth  rate of 3%.  The  discount  rate  applied  to the
forecasted  cash flows  represents  weighted  average cost of capital based upon
current debt and equity activity of eight public companies  representing a cross
section of worldwide  competitors of the reporting unit. We used a discount rate
of 12% in our calculation of fair value of the expected  future cash flows.  The
results of our test indicated that goodwill was not impaired.  The results would
not have changed had we used a discount rate of 11.5% or 12.5%.

Impairment of assets held for use

SFAS No. 144,  "Accounting for the Impairment or Disposal of Long-Lived Assets,"
requires us to assess the  recoverability  of the carrying  value of  long-lived
assets when an event of impairment  has occurred.  We must exercise  judgment in
assessing  whether  an  event  of  impairment  has  occurred.  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.  We concluded events of impairment had occurred in
our  semiconductor  materials  product  line,  which  is part  of the  specialty
materials  business,  in the fourth quarter of 2003, and performed an impairment
test. The results of our test indicated that our long-lived  assets held for use
were not impaired.

In 2002, we recorded pre-tax charges totaling $409 million  primarily related to
the photonics and conventional  television  product lines. In each circumstance,
behavior  of  external  parties,  including  customers  and  competitors,   were
considered in the  determination of whether an impairment was required.  We also
exercised  judgment in the  determination  of expected future cash flows against
which to compare the carrying value of the asset group being evaluated.  For the
impairment in 2002, we exercised  judgment in determining  the fair value of the
assets  from  which  the  impairment  charge  was  measured.  For  our  photonic
technologies  products,  we based the fair value of our long-lived assets on the
actual  results of recent asset  auctions of similar  equipment.  For the assets
related to our conventional television product line, we exercised judgment about
alternative  volume and sales price scenarios,  computed  discounted cash flows,
and assigned our best estimate of  probability to each  alternative.  We reduced
the useful lives of the fixed assets of CAV as a result of this assessment.

Restructuring charges and impairments resulting from restructuring actions

During 2003 and 2002, we recorded  write-downs of property,  plant and equipment
as a result of decisions to exit facilities, primarily in the Telecommunications
segment. Assets impaired were primarily equipment,  construction in progress and
buildings,  which were sold or abandoned.  We used  information  available  from
recent auctions of  telecommunications  equipment to estimate salvage value when
measuring impairment.  The estimated salvage values were very low, primarily due
to the depressed market for  telecommunications  related equipment.  The salvage
values of  property  impaired  were also  estimated  to be  minimal  as  certain
facilities will be abandoned and not sold. We have had significant  reversals in
2003,  and it is possible that actual results will differ from  assumptions  and
require adjustments to reserves.






Valuation allowances for deferred income taxes

SFAS No. 109,  "Accounting for Income Taxes,"  requires us to exercise  judgment
about our future  results in  assessing  the  realizability  of our deferred tax
assets.  At December  31,  2003,  Corning had gross  deferred tax assets of $2.1
billion.  We determined  that the likelihood of realization of certain  deferred
tax assets is less than 50% and recorded  valuation  allowances of $469 million.
If  future  taxable  income  differs  from our  estimate,  adjustments  to these
allowances will be required and will impact future net income.  See Income Taxes
and Note 9 (Income Taxes) to the Consolidated  Financial  Statements for further
detail.

Probability of litigation outcomes

SFAS No. 5, "Accounting for Contingencies,"  requires us to make judgments about
future events that are inherently uncertain.  In making determinations of likely
outcomes of litigation  matters,  we consider the evaluation of outside  counsel
knowledgeable  about each  matter,  as well as known  outcomes in case law.  See
Legal  Proceedings  for a detailed  discussion of the key litigation  matters we
face.  The  most  significant  matter  involving  judgment  is the PCC  asbestos
liability.  There are a number of factors bearing upon our potential  liability,
including the inherent complexity of a Chapter 11 filing, our history of success
in defending  ourselves against asbestos claims,  our assessment of the strength
of our  corporate  veil  defenses,  our  continuing  dialogue with our insurance
carriers and the claimants' representatives,  and other factors. We have reached
a tentative  settlement  on PCC as  disclosed in Legal  Proceedings  and Note 10
(Investments)  to the  Consolidated  Financial  Statements.  The  settlement  is
subject to a number of  contingencies,  including a favorable vote by 75% of the
asbestos claimants voting on the PCC Plan, and approval by the bankruptcy court.

Pension assumptions

In 2002, we made a change in assumption that impacted  pension expense in future
periods.  Specifically,  we lowered  our  expected  long-term  rate of return on
pension assets from 9% to 8.5%. We did not alter the nature of the pension trust
investments.  Asset  performance  in 2002 had been below the 9%  assumption.  As
such,  we  lowered  our  long-term  rate of  return  assumption.  In 2003,  this
increased  our  pension  expense as  measured  in  accordance  with SFAS No. 87,
"Employers'  Accounting for Pension,"  compared to amounts recorded in 2002. The
increase was  approximately  $8 million in 2003.  In 2003,  our actual return on
plan assets  approximated  20%;  however,  we will continue to hold our expected
long-term rate of return at 8.5%.

ENVIRONMENT

We have been named by the  Environmental  Protection  Agency under the Superfund
Act,  or by  state  governments  under  similar  state  laws,  as a  potentially
responsible  party for twelve active hazardous waste sites.  Under the Superfund
Act, all parties who may have  contributed  any waste to a hazardous waste site,
identified  by such  Agency,  are jointly and  severally  liable for the cost of
cleanup unless the Agency agrees  otherwise.  It is our policy to accrue for its
estimated   liability  related  to  Superfund  sites  and  other   environmental
liabilities  related  to  property  owned  and  operated  by us based on  expert
analysis and continual monitoring by both internal and external consultants.  We
have  accrued   approximately  $21  million  for  our  estimated  liability  for
environmental  cleanup and related  litigation at December 31, 2003.  Based upon
the  information  developed  to date,  we believe  that the accrued  amount is a
reasonable  estimate of our liability and that the risk of an additional loss in
an amount materially higher than that accrued is remote.

NEW ACCOUNTING STANDARDS

In December 2003, the Financial  Accounting  Standards  Board ("FASB")  issued a
revised  SFAS  No.  132,  "Employers'   Disclosures  about  Pensions  and  Other
Postretirement  Benefits." The revised standard requires incremental pension and
other  postretirement  benefit plan  disclosures to financial  statements and is
designed to improve  disclosure  transparency.  The adoption of this  accounting
standard  did not have any effect on our  results  of  operations  or  financial
position.

In January  2003,  the FASB  issued  Interpretation  No. 46,  "Consolidation  of
Variable Interest  Entities,  an Interpretation of Accounting  Research Bulletin
No. 51," ("FIN 46") which  requires all VIEs to be  consolidated  by the primary
beneficiary.  The primary  beneficiary  is the entity that holds the majority of
the beneficial  interests in the VIE. In addition,  the  interpretation  expands
disclosure requirements for both VIEs that are consolidated as well as VIEs from
which the entity is the holder of a significant,  but not the majority amount of
the beneficial interests. We have leased equipment from three VIEs for which the
sole  purpose is the leasing of  equipment to us. We assessed the impact of this
interpretation  and  determined  that we are the primary  beneficiary  of one of
these existing VIEs, and therefore,  began to consolidate  this entity beginning
on July 1, 2003.  At December 31, 2003,  the assets and debt of this entity were
$31 million and $34 million,  respectively. We also evaluated the impact of this
interpretation  on the two other  entities  and  determined  that we are not the
primary  beneficiary  for either  entity.  The assets and debt of these entities
total $12 million.  The adoption of this  interpretation did not have a material
effect on our results of operations or financial position.






In addition,  we adopted the following new standards in 2003, which did not have
a  material  impact  on  our  consolidated  financial  position  or  results  of
operations:

..    SFAS No. 143, "Accounting for Asset Retirement Obligations,"
..    SFAS No.  146,  "Accounting  for Costs  Associated  with  Exit or  Disposal
     Activities,"
..    FASB  Interpretation  No.  45,   "Guarantor's   Accounting  and  Disclosure
     Requirements for Guarantees,  Including Indirect Guarantees of Indebtedness
     of Others" ("FIN 45"),
..    SFAS No. 149,  "Amendment  of SFAS No. 133 on  Derivative  Instruments  and
     Hedging Activities," and
..    SFAS  No.  150,   "Accounting  for  Certain   Financial   Instruments  with
     Characteristics of both Liabilities and Equity."

Report of independent Registered Public Accounting Firm


PricewaterhouseCoopers LLP




To the Board of Directors and Shareholders of Corning Incorporated

In our opinion, the consolidated financial statements listed in the accompanying
index  present  fairly,  in all material  respects,  the  financial  position of
Corning Incorporated and its subsidiaries at December 31, 2003 and 2002, and the
results of their  operations and their cash flows for each of the three years in
the period ended  December 31, 2003 in  conformity  with  accounting  principles
generally accepted in the United States of America. In addition, in our opinion,
the financial  statement  schedule  listed in the  accompanying  index  presents
fairly, in all material respects, the information set forth therein when read in
conjunction with the related consolidated financial statements.  These financial
statements  and  financial  statement  schedule  are the  responsibility  of the
Company's  management;  our  responsibility  is to  express  an opinion on these
financial  statements and financial  statement  schedule based on our audits. We
conducted our audits of these statements in accordance with the standards of the
Public Company  Accounting  Oversight  Board (United  States).  Those  standards
require that we plan and perform the audit to obtain reasonable  assurance about
whether the financial  statements  are free of material  misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial  statements,  assessing the  accounting  principles
used and  significant  estimates made by management,  and evaluating the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

As discussed in Notes 1, 2 and 4 of the consolidated financial statements, as of
January 1, 2002,  the Company  ceased  amortization  of goodwill and changed its
method of accounting for discontinued  operations to conform with the provisions
of Statement of Financial  Accounting  Standards ("SFAS") No. 142, "Goodwill and
Other  Intangible  Assets" and SFAS No. 144,  "Accounting  for the Impairment or
Disposal of Long-Lived Assets", respectively.

Notes to Consolidated Financial Statements                                             Corning Incorporated and Subsidiary Companies
------------------------------------------------------------------------------------------------------------------------------------


1.   Summary of Significant Accounting Policies

Principles of Consolidation

The  consolidated  financial  statements  include the  accounts of all  entities
controlled by Corning and our majority-owned  domestic and foreign subsidiaries,
after  elimination  of all  material  intercompany  accounts,  transactions  and
profits.

The equity method of accounting is used for investments in associated  companies
which are not  controlled  by Corning  and in which our  interest  is  generally
between 20% and 50%. Our share of earnings or losses of associated companies, in
which at least  20% of the  voting  securities  is  owned,  is  included  in the
consolidated operating results.

We  consolidate  one  variable  interest  entity  in  which  we are the  primary
beneficiary.

On December 13, 2002, we completed the sale of the precision lens business to 3M
Company (3M).  Our  consolidated  statements  of  operations  and cash flows and
related notes present the precision lens business as a discontinued operation.

Certain amounts for 2002 and 2001 have been  reclassified to conform to the 2003
classifications.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America (GAAP) requires management to
make estimates and assumptions that affect amounts reported therein. Significant
estimates and assumptions in these  Consolidated  Financial  Statements  include
restructuring  and other charges and credits,  allowances for doubtful  accounts
receivable, estimates of future cash flows and other assumptions associated with
goodwill and long-lived asset impairment  tests,  estimates of the fair value of
assets held for disposal,  environmental and legal liabilities, income taxes and
deferred tax valuation  allowances,  and the determination of discount and other
rate assumptions for pension and postretirement  employee benefit expenses.  Due
to the  inherent  uncertainty  involved  in  making  estimates,  actual  results
reported in future periods may be different from these estimates.

Revenue Recognition

We  recognize  revenue  when it is realized or  realizable  and has been earned.
Product revenue is recognized when persuasive evidence of an arrangement exists,
the product has been  delivered and legal title and all risks of ownership  have
been transferred,  customer  acceptance has occurred,  and payment is reasonably
assured.  We reduce revenue for estimated product returns,  allowances and price
discounts based on past experience.

Foreign Currencies

Balance  sheet  accounts  of  foreign  subsidiaries  are  translated  at current
exchange rates and  statements of operations  accounts are translated at average
exchange  rates for the year.  Translation  gains and losses are  reported  as a
separate  component of accumulated other  comprehensive  income (loss).  Foreign
currency transaction gains and losses are included in current earnings.

Stock-Based Compensation

Pursuant  to  Statement  of  Financial  Accounting  Standards  (SFAS)  No.  123,
"Accounting  for  Stock-Based   Compensation  (SFAS  No.  123),"  we  apply  the
recognition and measurement  principles of Accounting  Principles  Board Opinion
No. 25 (APB No. 25),  "Accounting  for Stock Issued to  Employees," to our stock
options and other  stock-based  compensation  plans.  These plans are more fully
described in Note 19 (Stock Compensation Plans).

In  accordance  with APB No.  25,  compensation  expense  for stock  options  is
recognized in income based on the excess,  if any, of the quoted market price of
the stock at the  grant  date of the  award or other  measurement  date over the
amount an employee must pay to acquire the stock. Generally,  the exercise price
for stock options  granted to employees  equals or exceeds the fair market value
of our common stock at the date of grant.

The following table  illustrates  the effect on loss from continuing  operations
and loss per share if we had applied the fair value  recognition  provisions  of
SFAS No. 123 to stock-based employee  compensation.  The estimated fair value of
each Corning option is calculated using the Black-Scholes option-pricing model.

Short-Term Investments

Our   short-term   investments   consist  of  debt   securities   classified  as
available-for-sale,  which are  stated  at  estimated  fair  value.  These  debt
securities include U.S. treasury notes, state and municipal bonds,  asset-backed
securities, corporate bonds, commercial paper and certificates of deposit. These
investments are on deposit with a major financial institution.  Unrealized gains
and losses,  net of tax, are computed on the  first-in  first-out  basis and are
reported as a separate  component  of  accumulated  other  comprehensive  income
(loss) in shareholders' equity until realized.





1.   Summary of Significant Accounting Policies (continued)

Inventories

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

Restricted Cash and Investments

Restricted  cash and  investments  represent  cash and  investments  that we are
temporarily  unable to access  or funds set aside for other  legally  restricted
purposes.  Restricted cash consists primarily of cash provided as collateral for
performance bonds and self-insured workers' compensation liabilities. Restricted
investments  also include U.S.  treasury  securities  pledged as  collateral  to
secure the payments on a promissory note. The note was issued in connection with
a  one-time  dividend  that was  declared  upon  the  issuance  of the  Series C
convertible preferred stock.

Other Investments

Other investments  include equity securities for which Corning does not have the
ability to exercise significant  influence.  These investments are accounted for
under the cost method of accounting.  Equity  securities  that we are restricted
from  selling  beyond  one year are  carried  at cost.  Unrestricted  shares are
adjusted to market value at the end of each accounting period.  Unrealized gains
and losses are reported in a separate  component of  shareholders'  equity under
the caption  accumulated  other  comprehensive  income (loss).  A decline in the
value of other  investments below cost that is deemed to be other than temporary
is charged to earnings, resulting in a new cost basis for that investment.

Property and Depreciation

Land,  buildings and equipment  are recorded at cost.  Depreciation  is based on
estimated useful lives of properties using the straight-line  method.  Except as
described in Note 5 (Restructuring Actions) related to accelerated  depreciation
arising from restructuring programs, the estimated useful lives range from 20 to
40 years for buildings and 3 to 20 years for the majority of our equipment.

Goodwill and Other Intangible Assets

In June 2001, the Financial  Accounting Standards Board ("FASB") issued SFAS No.
141, "Business  Combinations," and SFAS No. 142 ("SFAS No. 142"),  "Goodwill and
Other  Intangible  Assets."  Among  other  provisions,  goodwill  is  no  longer
amortized but is subject to impairment tests at least annually.  We selected the
fourth quarter to perform the annual  impairment  test for goodwill.  We adopted
SFAS No. 142 on January 1, 2002.  We  completed  our initial  impairment  review
during the first quarter of 2002 and concluded a transitional  impairment charge
from the  adoption of the  standard  was not  required.  As  described in Note 4
(Impairment  of  Goodwill),  during the fourth  quarter of 2002,  we  recorded a
goodwill impairment charge in accordance with SFAS No. 142.

The following table presents a reconciliation  of reported net loss and loss per
share to  adjusted  net loss and loss per share,  as if SFAS No. 142 had been in
effect as of January 1, 2001 (in millions, except per share amounts):

-------------------------------------------------------------------------------------------------------------------------







1.   Summary of Significant Accounting Policies (continued)

Goodwill is allocated to our reporting  units. The reporting units with goodwill
allocated to them are  Telecommunications,  Display Technologies,  and specialty
materials.  SFAS No. 142 defines a reporting unit as an operating segment or one
level below an operating  segment.  SFAS No. 142 requires us to compare the fair
value  of the  reporting  unit to its  carrying  amount  on an  annual  basis to
determine if there is potential impairment.  We perform interim impairment tests
when  events or changes in  circumstances  occur that would more likely than not
reduce the fair value of a reporting unit below its carrying  value. If the fair
value of the reporting unit is less than its carrying  value, an impairment loss
is  recorded  to the  extent  that the fair  value of the  goodwill  within  the
reporting unit is less than its carrying value.  The fair value of the reporting
unit is determined based on discounted cash flows, market multiples or appraised
values as appropriate.

Other  intangible  assets  are  recorded  at cost  and  amortized  over  periods
generally ranging from 5 to 20 years.

Impairment of Long-Lived Assets

We  review  the  recoverability  of our  long-lived  assets,  such as plant  and
equipment,  intangible  assets  and  investments,  when  events  or  changes  in
circumstances  occur that indicate that the carrying value of the asset or asset
group may not be recoverable.  The assessment of possible impairment is based on
our ability to recover the  carrying  value of the asset or asset group from the
expected future pre-tax cash flows  (undiscounted  and without interest charges)
of the related operations. 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 these
cash flows are less than the  carrying  value of such asset or asset  group,  an
impairment loss is measured based on the difference between estimated fair value
and carrying  value.  Assets to be disposed are  written-down  to the greater of
their  fair  value or  salvage  value.  Fair  values  are  based on  assumptions
concerning  the amount and timing of  estimated  future  cash flows and  assumed
discount rates, reflecting varying degrees of perceived risk.

Treasury Stock

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

Income Taxes

We use the asset and liability  approach to account for income taxes. Under this
method,  deferred tax assets and  liabilities  are  recognized  for the expected
future tax  consequences of differences  between the carrying  amounts of assets
and liabilities and their  respective tax base using enacted tax rates in effect
for the year in which the  differences  are  expected to reverse.  The effect on
deferred tax assets and  liabilities  of a change in tax rates is  recognized in
income in the period when the change is enacted. Deferred tax assets are reduced
by a valuation  allowance when, in the opinion of management,  it is more likely
than not  that  some  portion  or all of the  deferred  tax  assets  will not be
realized.

Derivative Instruments

We  participate  in a variety of foreign  exchange  forward  contracts,  foreign
exchange  option  contracts  and interest  rate swaps entered into in connection
with the  management  of our exposure to  fluctuations  in foreign  exchange and
interest  rates.  These  financial  exposures  are  managed in  accordance  with
corporate policies and procedures.

All derivatives are recorded at fair value on the balance sheet.  Changes in the
fair  value of  derivatives  designated  as cash flow  hedges  and hedges of net
investments   in  foreign   operations   are  recorded  in   accumulated   other
comprehensive  income (loss).  Amounts are reclassified  from accumulated  other
comprehensive  income (loss) when the underlying  hedged item impacts  earnings.
Changes in the fair value of  derivatives  designated  as fair value  hedges are
recorded  currently  in  earnings  offset  to  the  extent  the  derivative  was
effective,  by the changes in the fair value of the hedged item.  Changes in the
fair value of  derivatives  not designated as hedging  instruments  are recorded
currently in earnings.

Effective  January  1, 2001,  Corning  adopted  SFAS No.  133,  "Accounting  for
Derivative  Instruments and Hedging  Activities," as amended by SFAS No. 137 and
SFAS No. 138. The adoption of SFAS No. 133 as of January 1, 2001,  resulted in a
cumulative after-tax credit to comprehensive income of $3 million. For the years
ended December 31, 2003 and 2001, respectively,  an after-tax loss of $3 million
and $4 million was recorded in "other expense,  net" for the ineffective portion
of cash flow hedges.





1.   Summary of Significant Accounting Policies (concluded)

We have issued foreign  currency  denominated debt that has been designated as a
hedge of the net investment in a foreign operation. The effective portion of the
changes  in fair  value  of the  debt  is  reflected  as a  component  of  other
comprehensive  income  (loss)  as  part  of  the  foreign  currency  translation
adjustment.  During 2001, the after-tax  amount included in other  comprehensive
income (loss) as a result of a net investment hedge was $6 million.

Product Warranties

Provisions for estimated  expenses related to product warranties are made at the
time the  products  are sold using  historical  experience  as a  prediction  of
expected  settlements.  Reserves  are  adjusted  when  experience  indicates  an
expected  settlement will differ from initial  estimates.  Reserves for warranty
items are included in other current liabilities.

New Standards Adopted

In December 2003, the FASB revised SFAS No. 132,  "Employers'  Disclosures about
Pensions  and Other  Postretirement  Benefits."  The revised  standard  requires
incremental  pension  and  other  postretirement  benefit  plan  disclosures  to
financial  statements and is designed to improve  disclosure  transparency.  The
adoption of this  accounting  standard did not have any effect on our results of
operations or financial position.

In January  2003,  the FASB  issued  Interpretation  No. 46,  "Consolidation  of
Variable Interest  Entities,  an Interpretation of Accounting  Research Bulletin
No. 51," ("FIN 46") which requires all variable interest entities ("VIEs") to be
consolidated by the primary  beneficiary.  The primary beneficiary is the entity
that holds the majority of the beneficial interests in the VIE. In addition, the
interpretation   expands   disclosure   requirements  for  both  VIEs  that  are
consolidated  as  well  as  VIEs  from  which  the  entity  is the  holder  of a
significant,  but not the majority amount of the beneficial  interests.  We have
leased  equipment  from three VIEs for which the sole  purpose is the leasing of
equipment to us. We assessed the impact of this  interpretation  and  determined
that  we are  the  primary  beneficiary  of  one of  these  existing  VIEs,  and
therefore,  began to  consolidate  this  entity  beginning  on July 1, 2003.  At
December 31,  2003,  the assets and debt of this entity were $31 million and $34
million,  respectively.  We also evaluated the impact of this  interpretation on
the two other  entities and determined  that we are not the primary  beneficiary
for either entity. The assets and debt of these entities total $12 million.  The
adoption of this interpretation did not have a material effect on our results of
operations or financial position.

In addition,  we adopted the following new standards in 2003, which did not have
a  material  impact  on  our  consolidated  financial  position  or  results  of
operations:

..    SFAS No. 143, "Accounting for Asset Retirement Obligations,"
..    SFAS No.  146,  "Accounting  for Costs  Associated  with  Exit or  Disposal
     Activities,"
..    FASB  Interpretation  No.  45,   "Guarantor's   Accounting  and  Disclosure
     Requirements for Guarantees,  Including Indirect Guarantees of Indebtedness
     of Others" ("FIN 45"),
..    SFAS No. 149,  "Amendment  of SFAS No. 133 on  Derivative  Instruments  and
     Hedging Activities," and
..    SFAS  No.  150,   "Accounting  for  Certain   Financial   Instruments  with
     Characteristics of both Liabilities and Equity."

2.   Discontinued Operations

On December 13, 2002, we completed the sale of our precision lens business to 3M
for cash proceeds up to $850  million,  of which $50 million was deposited in an
escrow account.  During 2002, we received approximately $800 million in cash and
recorded  a gain on the  sale of  $415  million,  net of  tax,  in  income  from
discontinued  operations in the  consolidated  statements of operations.  3M has
notified  Corning  that 3M  believes it has  certain  claims  arising out of the
representations  and warranties  made by Corning in connection  with the sale of
the precision  lens  business to 3M. The parties are  attempting to resolve such
claims.  In 2003, $1 million of the escrow  balance was used to pay state income
taxes.  At December 31, 2003,  approximately  $49 million  remains in the escrow
account,  and no other gain on the sale of the  precision  lens business will be
recognized until such claims are resolved.

The precision lens business  operating  results and cash flows have been removed
from our results of  continuing  operations  for all periods  presented and have
been  excluded  from the  operating  segments  data.  There were no results from
discontinued operations in 2003.

3.   Inventory Write-down

During the second quarter of 2001, major customers in the photonic  technologies
product line reduced their order  forecasts and canceled  orders already placed.
As a result,  we  determined  that certain  products  were not likely to be sold
during their product life cycle.  We recorded a charge to write-down  excess and
obsolete inventory,  including estimated purchase  commitments,  of $273 million
($184 million after-tax), which is included in cost of sales in the consolidated
statement  of  operations.  In the  fourth  quarter  of  2001,  we  recorded  an
additional charge of $60 million ($37 million after-tax) for excess and obsolete
inventory  primarily  in the photonic  technologies  product line in response to
continued weak demand. This charge was also included in cost of sales.

During the second quarter of 2002, we favorably  resolved an open issue from the
second  quarter  of 2001 with a major  photonic  technologies'  customer,  which
resulted in the  recognition  of revenue of $14 million and pre-tax income of $3
million. This revenue was recognized in part on shipment of inventory previously
reserved.  In addition,  the business  settled an open matter with a significant
vendor,  which  resulted in the reversal of a vendor reserve of $20 million that
was included in the second  quarter 2001 charge.  In total,  the impact of these
settlements in the second quarter of 2002 was pre-tax income of $23 million.

4.   Impairment of Goodwill

2003 Annual Assessment

Due to market conditions in the telecommunications and semiconductor industries,
we performed goodwill impairment tests for our  Telecommunications and specialty
materials  reporting  units in the fourth  quarter of 2003.  The  results of our
impairment  tests  indicated that the fair value of each reporting unit exceeded
its book value.

2002 Charge

In the fourth  quarter of 2002,  we conducted  our annual  impairment  tests and
concluded that an impairment charge of $400 million ($294 million after-tax) was
necessary  to reduce the  carrying  value of goodwill in the  Telecommunications
reporting unit to its estimated fair value of $1.6 billion. The decrease in fair
value at the end of 2002 from that measured in the initial benchmark  assessment
on January 1, 2002 primarily reflected the following:

..    a delay in the timing of the  expected  recovery  from late 2002,  or early
     2003 to 2005,
..    a reduction in the short-term cash flow expectations of the fiber and cable
     business and a lower base from which the expected recovery will occur, and
..    a  reduction  in the short and  long-term  cash  flow  expectations  of the
     photonic technologies product line.

We retained valuation specialists to assist in the valuation of our tangible and
identifiable  intangible  assets for the purpose of determining the implied fair
value of goodwill at December 31, 2002.





4.   Impairment of Goodwill (concluded)

2001 Charge

During the first half of 2001, we experienced a significant decrease in the rate
of  growth  of  our  Telecommunications   segment,  primarily  in  the  photonic
technologies  product line due to a dramatic decline in infrastructure  spending
in the  telecommunications  industry,  and determined  that there were events of
impairment  within  photonics.  We  determined  that  our  goodwill  related  to
photonics was not recoverable under SFAS No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed of," which was the
governing GAAP guidance at that time. As a result,  we recorded a charge of $4.6
billion to impair a  significant  portion  of  goodwill,  of which $3.0  billion
related  to the  Pirelli  transaction  and  $1.6  billion  related  to  goodwill
resulting from the acquisition of NetOptix Corporation.

5.   Restructuring Actions

Corning  recorded net charges of $49 million  ($14 million  credit after tax and
minority  interest)  in 2003.  Major  actions  approved  and  initiated  in 2003
included the following:

..    the shutdown of our 51% owned venture Corning Asahi Video Products  Company
     (CAV),  which was a  manufacturer  of glass  panel and  funnels  for use in
     conventional tube televisions,
..    the sale and exit of our photonics  products within the  Telecommunications
     segment, and
..    the shutdown of two of our specialty materials manufacturing facilities.

Restructuring Charges
---------------------
The 2003  restructuring  charges of $41 million included $90 million of employee
separation costs (including  special  termination and curtailment losses related
to pension and  postretirement  health care plans) and $37 million in other exit
costs (principally lease termination and contract cancellation payments), offset
by an $86  million  credit  related to  previous  restructuring  actions.  These
credits  were  primarily  the  result of  revised  cost  estimates  of  existing
restructuring  plans and a decision  to not exit two small  cabling  sites.  The
charge  entailed  the  elimination  of  approximately  1,975 hourly and salaried
positions  including  involuntary   separation,   early  retirement  and  social
programs.  In addition,  we recorded a $20 million foreign  deferred tax benefit
adjustment  related to  restructuring  charges  recorded in 2002. This credit is
reflected in the consolidated statement of operations under, "Benefit for income
taxes."

Impairment of Plant and Equipment to be Shutdown or Disposed
------------------------------------------------------------
Corning  recorded a net credit of $21 million in 2003. This included $40 million
of charges to impair plant and equipment related to facilities to be shutdown or
disposed,  which  comprised $11 million for the North  Brookfield  semiconductor
materials  plant closure,  $14 million  related to a cabling plant,  $10 million
related to the final exit of photonics,  and $5 million of other various  costs.
The impairment charges were determined based on the amount by which the carrying
value  exceeded  the fair  market  value of the asset.  The charge was more than
offset by $61  million in credits  related to  previous  restructuring  actions.
These  credits were  primarily the result of our decision not to exit two of the
previous  cabling sites marked for shutdown in 2002 as well as proceeds on asset
disposals exceeding assumed salvage values.

Impairment of Cost Investments
------------------------------
In the first  quarter,  we recorded a $5 million charge for other than temporary
declines in certain cost investments in the  Telecommunications  segment. In the
third quarter,  we sold these  investments for $4 million in cash,  which was $1
million  more than  previously  expected.  We reported  this gain as a credit to
restructuring actions.

Loss on Sale of Photonics
-------------------------
We recorded a loss of $13 million in the third  quarter  when we  completed  the
sale of certain photonic  technologies assets to Avanex Corporation  ("Avanex").
In exchange  for our  photonics  assets and $22 million in cash,  we received 21
million   restricted  shares  of  Avanex  common  stock,   which  we  valued  at
approximately   $53  million.   These  shares  are  restricted   from  sale  for
approximately  one year at which point the  restrictions are lifted at intervals
beginning July 2004 and ending October 2005. As the shares become  unrestricted,
we  will  mark-to-market  the  shares  through  other  comprehensive  income  as
available-for-sale  securities.  The Avanex restricted shares are reflected as a
cost investment and recorded under  "Investments"  in our  consolidated  balance
sheet.  Approximately 400 employees of the photonic technologies products became
employees  of Avanex  in the  third  quarter.  The loss on sale  included  a $21
million reduction of our goodwill. See Note 10 (Investments) for further detail.





5.   Restructuring Actions (continued)

In addition to these restructuring  action costs, we also incurred the following
charges  in our  consolidated  statement  of  operations  related to the exit of
photonics:

..    an increase to the deferred tax valuation allowance by $21 million as we do
     not  expect to  realize  certain  deferred  tax  assets in Italy,  which is
     reflected in the consolidated  statement of operations under,  "Benefit for
     income taxes," and
..    a $7 million  impairment charge for equity  investments that were abandoned
     as part of the exit from photonics,  which is reflected in the consolidated
     statement of operations under, "Equity in earnings of associated companies,
     net of impairments."

Accelerated Depreciation
------------------------
We recorded $12 million of accelerated  depreciation as a result of our decision
to shutdown our semiconductor  materials  manufacturing  facility in Charleston,
South  Carolina by March 31, 2004. We will record an  additional  $36 million in
the first quarter of 2004 while the plant continues operating.

The  following  table  summarizes  the  charges,  credits  and  balances  of the
restructuring  reserves  as of and for the  year  ended  December  31,  2003 (in

Cash payments for employee-related costs will be substantially  completed by the
end of 2004, while payments for exit activities will be substantially  completed
by the end of 2005. We expect  approximately  one-half of the 2003 restructuring
charges to be paid in cash.

------------------------------------------------------------------------------------------------------------------------------------


As of December 31, 2003,  approximately  1,600 of the 1,975  employees  had been
separated  under the 2003 plans.  We expect the  remaining  to be  separated  by
December  31,  2004,  with the  majority to be separated by the end of the first
quarter of 2004.

2002 Restructuring Actions

The continued  decline in demand in the  Telecommunications  segment during 2002
required   additional   restructuring   beyond  that  taken  in  2001  to  bring
manufacturing  capacity in line with  revenue  projections.  We  recorded  total
charges of $1.3 billion ($929 million after-tax and minority  interest) over the
second,  third and fourth  quarters.  Actions  approved  and  initiated  in 2002
included the following:

..    permanent  closing of our optical fiber  manufacturing  facilities in Noble
     Park,  Victoria,  Australia,  and  Neustadt  bei Coburg,  Germany.  We also
     mothballed  our optical  fiber  manufacturing  facility  in Concord,  North
     Carolina and transferred  certain  capabilities  to our  Wilmington,  North
     Carolina facility,
..    reductions  in capacity  and  employment  in our cabling and  hardware  and
     equipment locations worldwide to reduce costs,
..    permanent   closure  of  our   photonic   technologies   thin  film  filter
     manufacturing facility in Marlborough, Massachusetts,
..    permanent  abandonment  of  certain  construction  projects  that  had been
     stopped   in  2001  in  the   fiber   and   cable   business   within   the
     Telecommunications segment,
..    closure   of   minor   manufacturing    facilities,    primarily   in   the
     Telecommunications segment,
..    closure and consolidation of research facilities,
..    elimination  of  positions  worldwide  through  voluntary  and  involuntary
     programs, and
..    divestiture of a portion of the controls and connectors product line in the
     Telecommunications segment.

In  addition,  we  impaired  cost  based  investments  in a  number  of  private
telecommunications companies based upon a decision in the fourth quarter of 2002
to divest the portfolio.

As of December 31, 2003, all of the 7,100  employees from the 2002 plan had been
separated.

2001 Restructuring Actions

In July and October of 2001, we announced a series of  restructuring  actions in
response to significant  deteriorating business conditions which began initially
in our Telecommunications segment, but eventually spread to our other businesses
as the year  progressed.  The following  actions were approved and undertaken in
2001:

..    closure of seven major  manufacturing  facilities and the  consolidation of
     several smaller facilities in the  Telecommunications  segment,  as well as
     the lighting and conventional television businesses,
..    discontinuation  of  our  initiative  in  Corning   Microarray   Technology
     products, part of our Life Sciences segment, and
..    elimination  of  approximately  12,000  positions  affecting  all operating
     segments, but especially impacting the photonic technologies,  hardware and
     equipment and the optical fiber and cable products.  This action included a
     selective  voluntary early retirement  program for certain  employees along
     with involuntary separations.

These actions  resulted in a pre-tax charge  totaling $953 million ($585 million
after-tax) for the year ended December 31, 2001.  Approximately one third of the
total charge was expected to be paid in cash.

6.   Impairment of Long-Lived Assets Other Than Goodwill

Given our restructuring actions and the market conditions facing our businesses,
at various  times  throughout  2001 to 2003,  we  performed  evaluations  of the
recoverability  of our  long-lived  assets.  In each  case  that  an  impairment
evaluation was required,  we developed  operating cash flow projections for each
strategic  alternative  and  made  assessments  as to the  probability  of  each
outcome.  If our  projections  indicated  that our long  lived  assets  were not
recoverable  through  future cash flows,  we were then  required to estimate the
fair value of the long-lived assets,  which were limited to property,  plant and
equipment, using the expected cash flow approach as a measure of fair value.

2003 Impairment Charges

In April 2003, we announced  that we had agreed with our partner to shutdown CAV
and wrote down its assets to their estimated salvage values. This resulted in an
impairment charge of $62 million ($19 million after-tax and minority interest).





6.   Impairment of Long-Lived Assets Other Than Goodwill (concluded)

Subsequent  to our decision to exit,  CAV signed a definitive  agreement to sell
tangible assets to Henan Anyang CPT Glass Bulb Group, Electronic Glass Co., Ltd.
(Henan  Anyang),  located in China,  for  amounts  exceeding  estimated  salvage
values.  Upon the receipt of $10  million in cash,  we  recognized  a $5 million
credit in restructuring. We expect the sale to be completed in the first half of
2004 at which time we anticipate recognizing an additional gain of approximately
$40 million ($13 million after-tax and minority interest).

2002 Impairment Charges

Photonic technologies
---------------------
In 2002, the  telecommunications  market  underwent a dramatic decline in demand
for its products as major buyers of network  equipment in this industry  reduced
their capital  spending.  This negative  trend was expected to continue into the
foreseeable  future.  As a result of our  impairment  evaluation,  the photonics
assets were written down to estimated salvage value, as this amount was our best
estimate of fair value. This resulted in a $269 million ($195 million after-tax)
write-down of the long-lived assets including $90 million related to patents.

Conventional video components
-----------------------------
In 2002,  the  market  was  impacted  by a decline  in demand  for  conventional
television glass and a dramatic increase in the importation of television glass,
tubes and sets from Asia.  These  trends  were  expected  to  continue  into the
foreseeable future. As a result of our impairment  evaluation,  the CAV's assets
were  written  down to their  estimated  fair  values.  This  resulted in a $140
million ($44 million after-tax and minority interest) write down of the assets.

2001 Impairment Charges

Photonic technologies
---------------------
In 2001, the telecommunications market's dramatic decline began. We performed an
asset impairment  evaluation of our photonics product line and incurred a charge
of $116 million to write-down intangible assets to their estimated fair values.

--------------------------------------------------------------------------------

At  December  31,  2003,  we  have  recorded   gross   deferred  tax  assets  of
approximately  $2.1 billion  with a valuation  allowance  of $469  million,  and
offset by deferred tax liabilities of $201 million.  The valuation  allowance is
primarily  attributable to the uncertainty regarding the realization of specific
foreign and state tax benefits,  net operating  losses and tax credits.  The net
deferred tax assets of  approximately  $1.5 billion  consist of a combination of
domestic (U.S. federal, state and local) and foreign tax benefits for: (a) items
which have been recognized for financial reporting  purposes,  but which will be
reported on tax  returns to be filed in the future,  and (b) loss and tax credit
carryforwards.  As  explained  further  below,  we have  performed  the required
assessment of positive and negative  evidence  regarding the  realization of the
net deferred tax assets in accordance with SFAS No. 109,  "Accounting for Income
Taxes." This  assessment  included  the  evaluation  of  scheduled  reversals of
deferred  tax  liabilities,  estimates of projected  future  taxable  income and
tax-planning  strategies.  Although  realization  is not  assured,  based on our
assessment,  we have concluded that it is more likely than not that such assets,
net of the existing valuation allowance, will be realized.

Net domestic deferred tax assets are approximately  $1.3 billion at December 31,
2003. Approximately $460 million of these net deferred tax assets relate to loss
and tax credit  carryforwards  that  expire  through  2023.  The  remaining  net
deferred tax assets comprise the following deductible temporary differences:

1.   other postretirement  benefits of $244 million, which will reverse over the
     next 40 to 50 years;
2.   restructuring  and other  liabilities  of $155 million,  which will reverse
     over the next 10 years;
3.   research and development  expenditures of $252 million,  which will reverse
     over the next 10 years; and
4.   other miscellaneous items of $178 million,  which will reverse, on average,
     over the next 10 years.

Approximately  10% of our net  domestic  deferred  tax assets  will be  realized
through net operating loss carrybacks  claims to be filed over the next three to
five years,  which will generate cash refunds during such period.  We expect the
remaining net domestic  deferred tax assets to be realized from future earnings.
However, in the event future earnings are insufficient, approximately 40% of our
net  domestic  deferred  tax assets  could be  realized  through a  tax-planning
strategy involving the sale of a non-strategic appreciated asset. Realization of
the remaining 50% of our net domestic deferred tax assets is solely dependent on
our ability to generate  sufficient  future taxable  income during  carryforward
periods of approximately 20 years.

The  minimum  amount of  domestic  future  taxable  income that would have to be
generated  to realize  this  portion of our  deferred tax assets is $1.7 billion
over at least 20 years.  Currently,  we are generating domestic losses. However,
our  forecast of domestic  taxable  income  indicates it is more likely than not
that the future  results of  operations  in the U.S.  will  generate  sufficient
taxable income to realize this portion of our deferred tax assets. Specifically,
we expect to incur  significantly lower domestic losses in 2004 and to return to
profitability  in the U.S. in 2005. Key assumptions  embedded in these near-term
forecasts follow:





9.   Income Taxes (concluded)

1.   Our 2004  U.S.  losses  will  decrease  as a result of the 2003 exit of the
     photonics technologies business and CAV.
2.   We expect to see improved earnings trends in our Telecommunications segment
     which is primarily in the U.S. This includes a significantly  lower loss in
     2004 and a return to  profitability  in 2005. This trend is partially being
     driven by the  realization  of lower  operating  costs as a result of prior
     years' restructuring actions. In addition, we are forecasting revenue to be
     flat or down  slightly in 2004 but  significantly  higher in 2005 due to an
     expected recovery in the telecommunications industry in 2005.
3.   Our  specialty  materials   semiconductor  business  will  generate  higher
     earnings in 2004 as a result of a recovery in the  semiconductor  equipment
     industry and lower  operating  costs as a result of the fourth quarter 2003
     restructuring  actions,  which  will be  completed  by the end of the first
     quarter of 2004.
4.   Our Display Technologies  segment will continue its rapid growth.  Although
     this business is largely based in Asia,  domestic earnings relating to this
     business  have  increased  in 2003 and are expected to continue to increase
     over the next  several  years,  in part due to an increase in U.S.  royalty
     income.
5.   We will  continue  to  sustain  modest  growth  in our  remaining  domestic
     businesses and,  except for the  restructuring  actions  announced prior to
     December 31,  2003,  we do not expect to incur any  significant  additional
     restructuring or impairment charges.

Our forecast of domestic income is based on assumptions about and current trends
in Corning's operating segments, and there can be no assurance that such results
will be achieved. We review such forecasts in comparison with actual results and
expected trends  quarterly for purpose of our  recoverability  assessment.  As a
result of this review,  if we determine that we will not return to profitability
in the U.S. in 2005 or if sufficient  future taxable income may not be generated
to fully  realize the net deferred tax assets,  we will  increase the  valuation
allowance by a charge to income tax expense by an amount equal to the portion of
the deferred tax assets to be realized through  projected future taxable income.
If we  record  such a  valuation  allowance,  we will  also  cease to  recognize
additional tax benefits on losses in the U.S.

The change in the total valuation allowance for the year ended December 31, 2003
was an increase of $52 million. The increase in the 2003 valuation allowance was
primarily due to the  uncertainty  regarding the  realization of certain foreign
tax benefits, foreign net operating losses and foreign tax credits.

We currently  provide income taxes on the earnings of foreign  subsidiaries  and
associated  companies to the extent  these  earnings  are  currently  taxable or
expected to be  remitted.  Taxes have not been  provided on  approximately  $1.2
billion of accumulated  foreign unremitted earnings which are expected to remain
invested indefinitely.

We  do  not  provide  income  taxes  on  the  post-1992   earnings  of  domestic
subsidiaries that we expect to recover tax-free without significant cost. Income
taxes have been provided for post-1992 unremitted earnings of domestic corporate
joint ventures that we do not expect to recover tax-free. Unremitted earnings of
domestic  subsidiaries  and corporate  joint ventures that arose in fiscal years
beginning on or before December 31, 1992 have been indefinitely reinvested.

In 2001, tax legislation was enacted in the U.S. that  temporarily  extended the
net  operating  loss  carryback  period  from  two to  five  years.  Due to this
legislative  change,  we were  able to  carryback  the  2002  U.S.  federal  net
operating loss and claim a refund that would not have otherwise been  available.
Corning received a $191 million refund in the first quarter of 2003.

Dow  Corning,   a  50%-owned  U.S.  based   manufacturer  of  silicone  products
represented  $185 million of our investments  accounted for by the equity method
at December 31, 2003.  In 1995,  Corning  fully  impaired its  investment of Dow
Corning upon its entry into bankruptcy  proceedings and did not recognize equity
earnings from the second quarter of 1995 through the end of 2002.  Corning began
recognizing  equity  earnings  in the  first  quarter  of 2003  when  management
concluded  that its emergence  from  bankruptcy  protection  was  probable.  See
discussion below for additional  information for a history of this matter.  With
the exception of the remote  possibility of a future bankruptcy  related charge,
Corning considers the difference between the carrying value of its investment in
Dow  Corning and its 50% share of Dow  Corning's  equity to be  permanent.  This
difference is $270 million.

     and events that are directly associated with the reorganization.





10.  Investments (continued)

Dow  Corning  filed for  bankruptcy  protection  to address  pending and claimed
liabilities arising from many thousand  breast-implant  product lawsuits each of
which typically sought damages in excess of one million dollars.  On November 8,
1998, Dow Corning and the Tort Claimants  Committee jointly filed a revised Plan
of  Reorganization  ("Joint  Plan") which  provided for the  settlement or other
resolution of implant claims. The Joint Plan included releases for third parties
(including   Corning  and  The  Dow  Chemical   Company   ("Dow   Chemical")  as
shareholders) in exchange for contributions to the Joint Plan. By an order dated
November 30, 1999,  the  Bankruptcy  Court  confirmed  the Joint Plan,  but with
certain  limitations  concerning  the third party  releases as  reflected  in an
opinion  issued on December 21, 1999.  On November 13, 2000,  the U.S.  District
Court for the Eastern  District  of Michigan  reversed  the  Bankruptcy  Court's
order, restored the third-party releases,  and confirmed the Joint Plan. Certain
foreign  claimants,  the U.S.  government,  and  certain  other  tort  claimants
appealed from the District Court's order. On January 29, 2002, the U.S. Court of
Appeals for the Sixth Circuit affirmed the  determinations  made in the District
Court with respect to the foreign claimants,  but remanded to the District Court
for  further  proceedings  with  respect  to  certain  lien  claims  of the U.S.
government and with respect to the findings  supporting the non-debtor  releases
in favor of Dow Corning's  shareholders,  foreign subsidiaries and insurers. The
Plan  proponents  have settled the lien claims of the U.S.  government  for $9.8
million to be paid from the  Settlement  Fund under the Plan.  On  December  11,
2002, the District Court entered further findings and conclusions supporting the
non-debtor  releases.  Certain tort claimants filed appeals to the U.S. Court of
Appeals for the Sixth  Circuit from the  District  Court's  order.  One group of
foreign claimants has settled and dismissed their appeal,  leaving a grouping of
approximately  50  plaintiffs  from  Nevada  as the  remaining  appellants.  The
appellate  process may take another 6 months. If the Joint Plan with shareholder
releases is upheld after all  appeals,  any  remaining  personal  injury  claims
against Corning in these matters will be channeled to the resolution  procedures
under the Joint Plan. If the Joint Plan with shareholder  releases is not upheld
after all appeals,  Corning would expect to defend any remaining  claims against
it (and any new claims) on the same  grounds  that led to a series of orders and
judgments  dismissing  all claims  against us in the federal  courts and in many
state courts as described  under the heading  Implant Tort Lawsuits  immediately
hereafter.  Management  believes that the claims against  Corning lack merit and
that the risk of material impact on Corning's financial statements is remote.

Under the terms of the Joint Plan, Dow Corning will establish a Settlement Trust
and a  Litigation  Facility to provide a means for tort  claimants  to settle or
litigate  their claims.  Dow Corning would have the obligation to fund the Trust
and  the  Facility,  over  a  period  of up  to 16  years,  in an  amount  up to
approximately  $3.3 billion,  subject to the  limitations,  terms and conditions
stated in the Joint Plan. Corning and Dow Chemical have each agreed to provide a
credit  facility  to Dow  Corning  of up to $150  million  ($300  million in the
aggregate),  subject to the terms and  conditions  stated in the Joint Plan. The
Joint Plan also provides for Dow Corning to make full payment,  through cash and
issuance of senior notes,  to its commercial  creditors.  These  creditors claim
approximately  $810 million in  principal  plus an  additional  sum for pendency
interest,  costs and fees from the  petition  date (May 15,  1995)  through  the
effective  date under the Plan when payment is made.  The  commercial  creditors
have  contested  the  Bankruptcy  Court's   disallowance  of  their  claims  for
post-petition  interest at default  rates of interest,  and have appealed to the
District Court. The District Court heard oral arguments on this appeal on May 2,
2002, and has not ruled.  The amount of additional  interest,  costs and fees at
issue in these claims against Dow Corning is approximately $100 million pre-tax.

Pittsburgh Corning Corporation ("PCC")
--------------------------------------

Corning and PPG  Industries,  Inc.  ("PPG") each own 50% of the capital stock of
PCC. Over a period of more than two decades,  PCC and several  other  defendants
have been named in numerous  lawsuits  involving claims alleging personal injury
from  exposure  to  asbestos.  On April  16,  2000,  PCC filed  for  Chapter  11
reorganization in the United States Bankruptcy Court for the Western District of
Pennsylvania.  As of the  bankruptcy  filing,  PCC had in excess of 140,000 open
claims  and had  insufficient  remaining  insurance  and assets to deal with its
alleged current and future liabilities. More than 100,000 additional claims have
been  filed  with PCC after  its  bankruptcy  filing.  At the time PCC filed for
bankruptcy  protection,  there were approximately  12,400 claims pending against
Corning in state court lawsuits  alleging various theories of liability based on
exposure to PCC's asbestos products and typically requesting monetary damages in
excess of one million  dollars per claim.  Corning has defended  those claims on
the basis of the separate  corporate  status of PCC and the absence of any facts
supporting  claims of direct  liability  arising from PCC's  asbestos  products.
Corning  is  also   currently   named  in   approximately   11,200  other  cases
(approximately  40,700  claims)  alleging  injuries  from  asbestos  and similar
amounts  of  monetary  damages  per  claim.  Those  cases  have been  covered by
insurance  without  material impact to Corning to date.  Asbestos  litigation is
inherently  difficult,  and past  trends in  resolving  these  claims may not be
indicators of future outcomes.

In the  bankruptcy  court,  PCC in April 2000 obtained a preliminary  injunction
against the prosecution of asbestos  actions arising from PCC's products against
its two  shareholders  to afford the  parties a period of time ("the  Injunction
Period") in which to negotiate a plan of  reorganization  for PCC ("PCC  Plan").
The Injunction  Period was extended on several  occasions  through September 30,
2002, and later for a period from December 23, 2002,  through  January 23, 2003,
and was  reinstated  as of  April  22,  2003,  and will  now  continue,  pending
developments with respect to the PCC Plan as described below.





10.  Investments (concluded)

On May 14, 2002,  PPG announced that it had agreed with certain of its insurance
carriers and  representatives  of current and future  asbestos  claimants on the
terms of a  settlement  arrangement  applicable  to claims  arising  from  PCC's
products. The announced arrangement would permit PPG and certain of its insurers
to make  contributions  of cash over a period of years,  PPG's shares in PCC and
Pittsburgh  Corning  Europe N.V.  (PCE),  a Belgian  corporation,  and an agreed
number of shares of PPG's  common  stock in return for a release and  injunction
channeling claims against PPG into a settlement trust under the PCC Plan.

On  March  28,  2003,  Corning  announced  that it had  reached  agreement  with
representatives  of  current  and  future  asbestos  claimants  on a  settlement
arrangement  that will be  incorporated  into the PCC Plan.  This  settlement is
subject to a number of  contingencies,  including a favorable vote by 75% of the
asbestos claimants voting on the PCC Plan, and approval by the bankruptcy court.
Corning's  settlement  will  require  the  contribution,  when the Plan  becomes
effective,  of its equity  interest in PCC, its one-half equity interest in PCE,
and 25 million shares of Corning common stock.  Corning also will be making cash
payments of $136  million  (net  present  value as of December  31, 2003) in six
installments beginning in June 2005 assuming the Plan is effective. Corning will
accelerate the cash funding,  if necessary,  to maximize the  realization of tax
benefits.  In addition,  Corning  will assign  policy  rights or proceeds  under
primary  insurance  from 1962 through 1984, as well as rights or proceeds  under
certain  excess  insurance,  most of which  falls  within the  period  from 1962
through 1973. In return for these  contributions,  Corning  expects to receive a
release  and  an  injunction  channeling  asbestos  claims  against  it  into  a
settlement trust under the PCC Plan.

Corning  recorded an initial charge of $298 million ($192 million  after-tax) in
the period ending March 31, 2003 to reflect the settlement terms.  However,  the
amount of the charge for this settlement  requires adjustment each quarter based
upon  movement in  Corning's  common  stock price prior to  contribution  of the
shares to the  trust.  Corning  recorded  total  charges of $413  million  ($263
million  after-tax) to reflect the settlement and to mark-to-market the value of
Corning  common  stock for the year ended  December  31,  2003.  This charge was
previously  reported as a nonoperating  charge in our 2003 Quarterly  Reports on
Form 10-Q.  Effective with this Annual Report on Form 10-K, we have reclassified
this charge to operating expenses in the consolidated statements of operations.

Two of Corning's  primary  insurers and several  excess  insurers have commenced
litigation for a declaration of the rights and  obligations of the parties under
insurance  policies,  including  rights that may be  affected by the  settlement
arrangement  described  above.  Corning is  vigorously  contesting  these cases.
Management is unable to predict the outcome of this insurance litigation.

The PCC Plan, a disclosure  statement and various supplement Plan documents were
filed with the Court in the second quarter of 2003. Additional supplemental plan
documents  were filed in  mid-August  2003.  In October  2003,  the Court held a
hearing to review the disclosure  documents.  The Court has announced a schedule
projecting  that the Plan and  disclosure  documents will be mailed to creditors
for  voting  expected  to  be  completed  in  March  2004,  to  be  followed  by
confirmation  hearings in May 2004. Although the confirmation of the PCC Plan is
subject to a number of  contingencies,  management  believes  that the  asbestos
claims against Corning will be resolved  without  additional  material impact on
the company's financial  statements and (apart from the quarterly  adjustment in
the value of 25 million  shares of Corning  common  stock)  believes the risk of
additional loss is remote.

Other Investments

At December 31, 2003, other investments primarily represent our current holdings
of 19 million  shares of Avanex  common  stock.  These  shares were  received as
proceeds from the sale of certain  photonic assets to Avanex.  Approximately  17
million shares or 88% of these shares are contractually restricted from sale for
more than one year. As such, these restricted  shares have been accounted for at
cost.  Shares  of  Avanex  stock  that are  saleable  within  one year have been
adjusted  to  market  value  at  December  31,  2003  and are  accounted  for as
available-for-sale securities.

At December 31, 2003,  the fair value and cost of our equity  securities was $67
million and $62 million,  respectively.  The  difference  between fair value and
cost is due to gross unrealized  gains of $5 million  primarily on Avanex stock.
At December 31, 2002,  the fair value and cost of our equity  securities was $23
million.

Proceeds from sales of other  investments were $4 million and $1 million in 2003
and 2002, respectively,  and related net realized losses included in income were
$8 million and $1 million, respectively.

In 2002, we decided to divest our portfolio of cost based investments related to
start-up  companies  with  emerging   technologies  in  the   telecommunications
industry. As a result, we impaired the portfolio to estimated fair market value.

14.  Long-Term Debt and Loans Payable (continued)

At December 31, 2003 and 2002, the weighted-average  interest rate on short-term
borrowings was 5.7% and 5.5%, respectively.

Based on borrowing rates currently  available to us for loans with similar terms
and  maturities,  the fair value of long-term  debt was $3.0 billion at December
31, 2003.

The following  table shows the  maturities by year of total  long-term  debt and
loans payable obligations at December 31, 2003 (in millions):
--------------------------------------------------------------------------------

  2004            2005               2006             2007            2008-2030
--------------------------------------------------------------------------------

  $146            $590                $46             $113             $1,932
--------------------------------------------------------------------------------

The 7.625% debentures and the zero coupon  convertible  debentures are presented
in the above table as due in 2004 and 2005, respectively,  which is the earliest
possible redemption date.

We  have  convertible  debt  of  $665  million  due  November  1,  2008  that is
convertible into approximately 69 million shares of common stock at an effective
conversion  price  of  $9.675  per  share.  The  debentures  are  available  for
conversion  into 103.3592  shares of Corning common stock if certain  conditions
are met.  Each  $1,000  debenture  was issued at par and pays  interest  of 3.5%
semi-annually on May 1 and November 1 of each year. We may repurchase securities
at certain redemption prices beginning on November 8, 2004.

We have $385  million of zero coupon  convertible  debentures  outstanding.  The
initial price of the debentures was $741.92 with a 2% annual yield.  Interest is
compounded  semi-annually with a 25% conversion factor. The remaining debentures
mature on November 8, 2015, and are convertible  into  approximately  17 million
shares of Corning  common stock at the rate of 8.3304 per $1,000  debenture.  We
may call the debentures at any time on or after November 8, 2005. The debentures
may be put to us for  $819.54 on  November  8, 2005 and  $905.29 on  November 8,
2010. The holder can convert the debenture into Corning common stock at any time
prior to maturity or redemption.  We have the option of settling this obligation
in cash, common stock, or a combination of both.

During the years ended December 31, 2003 and 2002, we repurchased  and retired a
significant  portion of our zero coupon  convertible  debentures due November 8,
2015. In 2003, we repurchased and retired 1,531,000  debentures with an accreted
value of $1.2 billion for cash of approximately $1.1 billion through open market
purchases and a public  tender offer and recorded a net gain of $55 million.  We
also issued 6.5 million  shares of common  stock from  treasury in exchange  for
55,000  debentures  with an accreted  value of $43 million,  and we recognized a
charge of $35 million reflecting the fair value of the incremental shares issued
beyond those required by the terms of the debentures. The increase in equity due
to the issuance of shares from treasury  stock was $77 million.  We recorded the
net gain of $20  million on these  repurchases  as a  component  of income  from
continuing operations.

In addition to our zero coupon  debentures,  we  repurchased  and retired 60,000
euro notes due 2005 with a book value of 60 million euros for cash of 63 million
euros  (including  accrued  interest) or $70  million.  We recorded a loss of $1
million on the transaction.

We also have $100 million of convertible  subordinated notes bearing interest at
4.875%,  due in 2008. The notes are convertible into 6 million shares of Corning
common stock at a conversion price of approximately $16 per share.





14.  Long-Term Debt and Loans Payable (concluded)

We have full access to a $2.0 billion  revolving line of credit with a syndicate
of banks.  The line of credit  expires in August 2005.  There were no borrowings
under the  agreement  at December  31,  2003.  The  revolving  credit  agreement
provides for  borrowing of U.S.  dollars and  Eurocurrency  at various rates and
supports our commercial  paper program when available.  The facility  includes a
covenant  requiring  us to  maintain a total  debt to total  capital  ratio,  as
defined, not greater than 60%. At December 31, 2003, this ratio was 34%.

15.  Employee Retirement Plans

Defined Benefit Plans

We  have  defined   benefit   pension  plans  covering   certain   domestic  and
international  employees.  Our  funding  policy  has  been  to  contribute,   as
necessary, an amount in excess of the minimum requirements determined jointly by
us and our  consulting  actuaries  to achieve the  company's  long-term  funding
targets. In 2003, we made a voluntary  incremental  contribution of $160 million
to the pension trust.

In 2000,  we amended our U.S.  pension  plan to include a cash  balance  pension
feature.  All salaried and non-union  hourly employees hired before July 1, 2000
were given the choice of staying in the existing  plan or  participating  in the
cash balance plan beginning January 1, 2001. Salaried employees hired after July
1, 2000  automatically  became  participants in the new cash balance plan. Under
the cash balance plan,  employee accounts are credited monthly with a percentage
of  eligible  pay based on age and years of  service.  Benefits  are 100% vested
after five years of service.

Corning and certain of its domestic subsidiaries also offer 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. Prior to January 1, 2003, our principal
retiree  medical plans  required  retiree  contributions  each year equal to the
excess of medical cost increases over general  inflation  rates.  In response to
rising health care costs, effective January 1, 2003, we changed our cost-sharing
approach for retiree medical coverage. For current retirees (including surviving
spouses) and active employees eligible for the salaried retiree medical program,
we are placing a "cap" on the amount we will  contribute  toward retiree medical
coverage in the future. The cap will equal 150% of our 2001 contributions toward
retiree medical benefits.  Once our  contributions  toward retiree medical costs
reach  this cap,  impacted  retirees  will  have to pay the  excess  amount,  in
addition to their regular contributions for coverage.

We use a December 31 measurement date for the majority of our plans.

Medicare Prescription Drug, Improvement and Modernization Act of 2003
---------------------------------------------------------------------

In December 2003, the Medicare Prescription Drug,  Improvement and Modernization
Act of 2003 (the Act) was passed which expands Medicare to include an outpatient
prescription  drug benefit  beginning in 2006. In January 2004,  the FASB issued
Staff Position No. FAS 106-1, "Accounting and Disclosure Requirements Related to
the Medicare Prescription Drug,  Improvement and Modernization Act of 2003 ("FSP
No. 106-1")," which provides  preliminary  accounting guidance on how to account
for the effects of the Act on postretirement  benefit plans. As permitted by FSP
No. 106-1,  we have elected to defer  accounting for the impact of the Act until
the FASB issues final accounting  guidance later in 2004. Such guidance from the
FASB is pending  and that  guidance,  when  issued,  could  require us to change
previously reported  information.  We are currently evaluating the impact of the
Act on our postretirement benefit plans.

Plan Assets (domestic plans only)

The total fair value of  domestic  plan  assets at  December  31, 2003 is $1,672

15.  Employee Retirement Plans (concluded)

We have an investment policy for domestic pension plans with a primary objective
to adequately  provide for both the growth and  liquidity  needed to support all
current and future benefit payment  obligations.  The investment  strategy is to
invest in a  diversified  portfolio  of assets which are expected to satisfy the
above objective and produce both absolute and risk adjusted returns  competitive
with  a  benchmark   that  is  60%  Russell  3000  Index  and  40%  Lehman  Long
Government/Credit  Index.  The  strategy  includes  the  following  target asset
allocation:

Equity Securities                    50%
Fixed Income Securities              32%
Real Estate                           8%
Other                                10%
                                   -----
    Total                           100%

A tactical allocation mandate, which is part of the overall investment strategy,
allows the actual  allocation  in equity  securities to be reduced by maximum of
10% relative to the total based on market valuations.

Equity  securities  include  Corning  common stock in the amount of $5.7 million
(0.3% of total plan  assets)  and $1.8  million  (0.1% of total plan  assets) at
December 31, 2003 and 2002, respectively.

Cash Flows Data (domestic plans only)

Other Benefit Plans

We  offer  defined   contribution   plans  covering  employees  meeting  certain
eligibility   requirements.   On  January  1,  2003,  we  reduced  our  matching
contributions  to the domestic Corning  Incorporated  Investment Plan by 2.5% of
pay for all salaried employees.  This reduction was temporary,  and we increased
our contributions to prior levels on January 1, 2004. Total consolidated defined
contribution  plan expense was $24 million,  $44 million and $56 million for the
years ended December 31, 2003, 2002 and 2001, respectively.

16.  Commitments, Contingencies, Guarantees and Hedging Activities

Commitments, Contingencies and Guarantees

In 2003, we adopted the initial  recognition and  measurement  provisions of FIN
45. We do not routinely  provide  significant  third-party  guarantees and, as a
result,  this  interpretation  has not had a material effect on our consolidated
financial statements.  The initial recognition and measurement provisions of FIN
45 are applicable on a prospective  basis to guarantees issued or modified after
December 31, 2002.

We provide financial guarantees and incur contingent  liabilities in the form of
purchase price adjustments related to attainment of milestones, stand-by letters
of credit and performance  bonds.  These guarantees have various terms, and none
of these guarantees are individually significant.

Total  rental  expense was $66  million  for 2003,  $85 million for 2002 and $89
million for 2001.

Corning and PPG each own 50% of the capital  stock of PCC. PCC and several other
defendants  have been  named in  numerous  lawsuits  involving  claims  alleging
personal injury from exposure to asbestos.  See Note 10 (Investments) for a more
complete discussion.

The ability of certain  subsidiaries and associated  companies to transfer funds
is limited by  provisions  of certain  loan  agreements  and foreign  government
regulations.  At  December  31,  2003,  the  amount  of equity  subject  to such
restrictions  for  consolidated  subsidiaries  totaled $43  million.  While this
amount is legally  restricted,  it does not result in  operational  difficulties
since we have generally permitted subsidiaries to retain a majority of equity to
support their growth  programs.  In addition,  we have provided other  financial
guarantees and contingent  liabilities in the form of purchase price adjustments
related to attainment of milestones,  stand-by letters of credit and performance
bonds.  We have  agreed to provide a credit  facility  related to Dow Corning as
discussed  in Note 10  (Investments).  The  funding  of the Dow  Corning  credit
facility is subject to events  connected to the  Bankruptcy  Plan.  The purchase
obligations  primarily  represent  take or pay  contracts  associated  with  our
hardware and equipment  operations.  We believe a significant  majority of these
guarantees and contingent liabilities will expire without being funded.

We  have  two  VIEs  that  are  not  consolidated  as we  are  not  the  primary
beneficiary.  The  assets  and debt of these  entities  total $12  million.  Our
maximum loss exposure as a result of our involvement  with these  unconsolidated
VIEs is approximately $18 million. This amount represents payments that would be
due to the VIE in the event of a total loss of the equipment. We carry insurance
coverage for this risk.

Hedging Activities

We operate and conduct business in many foreign countries. As a result, there is
exposure to potentially  adverse movement in foreign currency exchange rates. We
enter  into  foreign  exchange  forward  and  option  contracts  with  durations
generally  15 months or less to reduce our  exposure  to  exchange  rate risk on
foreign  source income and  purchases.  The  objective of these  contracts is to
neutralize  the  impact of  foreign  currency  exchange  rate  movements  on our
operating results.

We engage in foreign currency hedging activities to reduce the risk that changes
in exchange  rates will adversely  affect the eventual net cash flows  resulting
from the sale of  products  to foreign  customers  and  purchases  from  foreign
suppliers.  The hedge contracts  reduce the exposure to fluctuations in exchange
rate movements  because the gains and losses  associated  with foreign  currency
balances  and  transactions  are  generally  offset with gains and losses of the
hedge  contracts.  Because the impact of movements in foreign  exchange rates on
hedge contracts offsets the related impact on the underlying items being hedged,
these financial  instruments help alleviate the risk that might otherwise result
from currency exchange rate fluctuations.





16.  Commitments, Contingencies, Guarantees and Hedging Activities (concluded)

The following table (in millions) summarizes the notional amounts and respective
fair values of the derivative financial  instruments at December 31, 2003. These
contracts are held by Corning and its subsidiaries and mature at varying dates:
--------------------------------------------------------------------------------
                                          Notional Amount        Fair Value
--------------------------------------------------------------------------------
Foreign exchange forward contracts           $ 182                 $   3
Foreign exchange option contracts            $ 379                 $ (10)
--------------------------------------------------------------------------------

The  forward  and option  contracts  we use in  managing  our  foreign  currency
exposures contain an element of risk in that the counterparties may be unable to
meet the terms of the agreements. However, we minimize this risk by limiting the
counterparties   to  a  diverse  group  of   highly-rated   major  domestic  and
international   financial  institutions  with  which  we  have  other  financial
relationships.   We  are   exposed   to   potential   losses  in  the  event  of
non-performance by these counterparties; however, we do not expect to record any
losses  as a result  of  counterparty  default.  We do not  require  and are not
required to place collateral for these financial instruments.

17.  Shareholders' Equity

Preferred Stock

We have 10 million  authorized  shares of  Preferred  Stock,  par value $100 per
share.

Series A Junior Participating Preferred Stock
---------------------------------------------
Of the  authorized  shares,  we have  designated  2.4 million shares as Series A
Junior Participating Preferred Stock for which no shares have been issued.

In June 1996, the Board of Directors approved the renewal of the Preferred Share
Purchase Right Plan, which entitles  shareholders to purchase 0.01 of a share of
Series A Junior  Participating  Preferred  Stock upon the  occurrence of certain
events.  In addition,  the rights  entitle  shareholders  to purchase  shares of
common  stock at a 50%  discount in the event a person or group  acquires 20% or
more of our outstanding common stock. The preferred share purchase rights became
effective July 15, 1996 and expire July 15, 2006.

Series C Mandatory Convertible Preferred Stock
----------------------------------------------
In July and August 2002, we issued 5.75 million  shares of 7% Series C mandatory
convertible  preferred stock having a liquidation  preference of $100 per share,
plus  accrued and unpaid  dividends,  and  resulting  in gross  proceeds of $557
million.  The  mandatory  convertible  stock has an annual  dividend rate of 7%,
payable  quarterly  in cash.  The first  dividend  payment date was November 16,
2002.  The dividends  are also payable  immediately  upon  conversion to Corning
common stock.  At the time we issued the Series C convertible  stock, a one-time
dividend  was  declared for all  dividends  that will be payable  from  issuance
through the mandatory conversion date of August 16, 2005. We secured the payment
of the dividends through the issuance of a promissory note and used a portion of
the  proceeds  from the sale of the Series C preferred  stock to  purchase  $117
million of U.S.  treasury  securities  that were pledged as collateral to secure
the payments on the promissory  note. As a result,  net proceeds of the offering
were $440 million.

The  Series C  preferred  stock  will  automatically  convert  on the  mandatory
conversion  date of August 16,  2005,  into  between  50.813 and 62.5  shares of
Corning common stock,  depending on the then current  market price.  At any time
prior to the mandatory conversion date, holders may elect to convert in whole or
part of their  shares of Series C preferred  stock into 50.813  shares of common
stock plus an amount of cash  equal to the market  value at that time of the pro
rata share of the  collateral  portfolio  that secures the  promissory  note. At
December 31, 2003,  approximately  4.9 million  shares of the Series C preferred
stock had been converted into 248.8 million common shares.

As the closing  price of Corning  common stock was $1.60 on July 31,  2002,  the
holder could immediately convert the Series C preferred stock and obtain a value
of  $101.72  (50.813  shares  valued at $1.60 plus  $20.42 in future  dividends)
indicating that the preferred stock contains a beneficial  conversion feature of
$1.72 per preferred share. The beneficial  conversion totaled  approximately $10
million and was charged to additional paid in capital. The beneficial conversion
was also deducted from earnings  attributable to common shareholders in the 2002
earnings per share calculations.

Common Stock

In July 2003,  we  completed an equity  offering of 45 million  shares of common
stock generating net proceeds of approximately $363 million. This offering's net
proceeds were used to reduce debt through open market repurchases, public tender
offers or other methods,  and for general corporate purposes.  We invest the net
proceeds in short-term,  interest  bearing,  investment grade  obligations until
they are applied as described.





17.  Shareholders' Equity (concluded)

In May 2003,  we  completed  an equity  offering of 50 million  shares of common
stock  generating net proceeds of  approximately  $267 million.  We used the net
proceeds of this  offering and  approximately  $356 million of existing  cash to
reduce  debt  through a public  tender  offer in the  second  quarter of 2003 as
discussed in Note 14 (Long-Term Debt and Loans Payable).

On July 9, 2001, we announced the discontinuation of the payment of dividends on
our common stock.  Dividends  paid to common  shareholders  in 2001 totaled $112
million.

Treasury Stock

We did not  repurchase  any of our common stock in 2003.  On July 22,  2002,  we
repurchased  5.5  million  shares  of our  common  stock  for $23  million  in a
privately negotiated transaction.

18.  Loss Per Common Share

Basic loss per common share is computed by dividing loss  attributable to common
shareholders by the weighted-average number of common shares outstanding for the
period.  The net loss  attributable to common  shareholders  for 2002 is further
increased  by the  Series  C  mandatory  convertible  preferred  stock  dividend
requirement.

Diluted loss per common share is computed by dividing net loss  attributable  to
common shareholders,  adjusted for the preferred dividend  requirements in 2002,
by the  weighted  average  shares  outstanding.  Since we  reported  a loss from
continuing  operations in 2003, 2002 and 2001, the diluted loss per share is the
same as basic, as any potentially  dilutive securities would reduce the loss per
share from continuing operations.



A reconciliation of the basic and diluted loss per common share from continuing operations computations for 2003, 2002 and 2001
follows (in millions, except per share amounts):

19.  Stock Compensation Plans (concluded)

Incentive Stock Plans

The Corning  Incentive  Stock Plan permits  stock grants,  either  determined by
specific performance goals or issued directly, in most instances, subject to the
possibility of forfeiture and without cash consideration.

In 2003, 2002 and 2001, grants of 1,842,000 shares,  88,500 shares and 1,028,000
shares,  respectively,  were made under this plan. The weighted-average price of
the grants was $10.61 in 2003, $7.15 in 2002 and $36.89 in 2001, respectively. A
total of 2.2 million  shares issued remain subject to forfeiture at December 31,
2003.

We  apply  APB  No.  25  accounting  for  our  stock-based  compensation  plans.
Compensation  expense is recorded  for awards of shares or share rights over the
period earned.  Compensation  expense of $1 million,  $1 million and $79 million
after-tax was recorded in 2003, 2002 and 2001, respectively.

SFAS No. 123 requires that reload options be treated as separate grants from the
related  original option grants.  Under our reload program,  upon exercise of an
option,  employees may tender  unrestricted shares owned at the time of exercise
to pay the  exercise  price and  related tax  withholding,  and receive a reload
option  covering  the same number of shares  tendered  for such  purposes at the
market  price on the date of exercise.  The reload  options vest in one year and
are only granted in certain circumstances according to the original terms of the
option being exercised. The existence of the reload feature results in a greater
number of options being measured.

For purposes of SFAS No. 123 disclosure,  the fair value of each option grant is
estimated on the date of grant using the Black-Scholes option-pricing model.

The following are  weighted-average  assumptions used for grants under our stock
plans in 2003, 2002 and 2001, respectively:
-------------------------------------------------------------------------------
For Options Granted During           2003             2002              2001
-------------------------------------------------------------------------------

Expected life in years                 5                 5                6
Risk free interest rate               2.9%              4.0%             4.8%
Dividend yield                                                          0.46%
Expected volatility                    79%               80%              75%
-------------------------------------------------------------------------------

We  discontinued  payment of  dividends  on our common  stock in July 2001.  The
dividend yield assumption applies to grants prior to July 2001.

Worldwide Employee Share Purchase Plan

In  addition to the Stock  Option  Plan and  Incentive  Stock  Plans,  we have a
Worldwide Employee Share Purchase Plan ("WESPP"). Under the WESPP, substantially
all  employees  can elect to have up to 10% of their  annual  wages  withheld to
purchase our common stock.  The purchase  price of the stock is 85% of the lower
of the beginning-of-quarter or end-of-quarter market price.

20.  Business Combinations and Divestitures

Purchases

The transactions  listed on the following table were all accounted for under the
purchase method of accounting.  We are responsible for estimating the fair value
of the assets and liabilities  acquired.  We have made estimates and assumptions
that affect the reported amounts of assets,  liabilities and expenses  resulting
from  such  acquisitions.  From  time  to  time  we  use  our  common  stock  as
consideration for business combinations.  The value of the common stock is based
upon the  average  closing  price of  Corning  common  stock for a range of days
surrounding  the  agreement  or   announcement   and  adjusted  for  a  discount
commensurate with restrictions on the shares, if applicable.

Divestitures

Photonic Technologies
---------------------
In July 2003, we completed  the sale of certain  optical  component  products to
Avanex. See Note 5 (Restructuring Actions) for a description of the transaction.

Appliance Controls Group
------------------------
In May 2002, we completed the sale of our appliance  controls  group,  which was
included in the controls and connectors  products within the  Telecommunications
segment. During 2002, we received proceeds of $30 million and realized a loss on
the sale of  approximately  $16 million  ($10 million  after-tax).  This loss is
included in  restructuring,  impairment  and other  charges in the  consolidated
statements of operations.

21.  Operating Segments

SFAS  No.  131,  "Disclosures  about  Segments  of  an  Enterprise  and  Related
Information,"  sets  standards for  reporting  information  regarding  operating
segments in financial  statements.  Operating segments are defined as components
of an enterprise about which separate financial information is available that is
evaluated  regularly by the chief  operating  decision maker, or decision making
group, in deciding how to allocate resources and in assessing  performance.  Our
Chief Operating  Decision Making group ("CODM") is comprised of the Chairman and
Chief Executive Officer,  Vice Chairman and Chief Financial  Officer,  President
and Chief  Operating  Officer,  President-Corning  Technologies,  Executive Vice
President-Chief   Administrative  Officer  and  Executive  Vice  President-Chief
Technology Officer.

We are a  world-leading  provider of optical  fiber and cable and  hardware  and
equipment products for the telecommunications  industry;  high-performance glass
for computer  monitors,  and other information  display  applications;  advanced
optical materials for the semiconductor  industry and the scientific  community;
scientific laboratory products for the scientific community;  ceramic substrates
for the automotive  industry;  specialized  polymer  products for  biotechnology
applications; and other technologies.

Effective  with the  first  quarter  of 2004,  we have  revised  our  reportable
operating    segments    from    Telecommunications    and    Technologies    to
Telecommunications,  Display Technologies,  Environmental Technologies, and Life
Sciences. The following provides a brief description of the products and markets
served by each reportable segment:

..    Telecommunications - manufactures optical fiber and cable, and hardware and
     equipment components for the worldwide telecommunications industry;
..    Display  Technologies - manufactures  liquid crystal display glass for flat
     panel displays;
..    Environmental  Technologies - manufactures  ceramic  substrates and filters
     for automobile and diesel applications; and
..    Life Sciences - manufactures  glass and plastic  consumables for scientific
     applications.

The change in our segment  presentation  reflects how Corning's  CODM  allocates
resources and assesses the performance of its businesses. Specifically, the CODM
is  increasing  its  level  of  review  of  the  Display   Technologies  segment
significantly  due to the recent increase in growth and capital spending in that
segment.  In addition,  the CODM is increasing  its review of the  Environmental
Technologies  and Life Sciences  segments to strengthen the overall  balance and
stability of Corning's portfolio of businesses.





21.  Operating Segments (continued)

All other  operating  segments that do not meet the  quantitative  threshold for
separate reporting (e.g. conventional video components, semiconductor materials,
and ophthalmic  products),  certain corporate  investments (e.g. Dow Corning and
Steuben),  discontinued  operations,  and  unallocated  expenses (e.g. and other
corporate  items) have been  grouped as  "Unallocated  and  Other".  Unallocated
expenses   include:   research  and  other  expenses  related  to  new  business
development;  amortization  of  goodwill;  gains or  losses on  repurchases  and
retirement  of  debt;   charges   related  to  the  asbestos   litigation;   and
restructuring  and  impairment  charges  related to the  corporate  research and
development or staff  organizations.  Unallocated  and Other also represents the
reconciliation   between  the  totals  for  the  reportable   segments  and  our
consolidated total.

We prepared the financial results for our operating  segments on a basis that is
consistent  with  the  manner  in  which we  internally  disaggregate  financial
information to assist in making  internal  operating  decisions.  We include the
earnings of equity  affiliates  that are closely  associated  with our operating
segments in the  respective  segment's  net income.  We have  allocated  certain
common  expenses  among  segments  differently  than we  would  for  stand-alone
financial  information  prepared in accordance with GAAP. These expenses include
interest,  taxes  and  corporate  functions.  Segment  net  income  may  not  be
consistent with measures used by other companies. The accounting policies of our
operating  segments are the same as those applied in the consolidated  financial
statements.  Revenue  attributed to geographic areas is based on the location of
the customer.

21.  Operating Segments (continued)

(1)  Depreciation   expense  for  Corning's   reportable  segments  includes  an
     allocation  of   depreciation  of  corporate   property  not   specifically
     identifiable to a segment.  Related depreciable assets are not allocated to
     segment assets.
(2)  Non-direct research,  development and engineering expenses are allocated to
     segments based upon direct project spending for each segment.
(3)  Related tax benefit:
        Year ended December 31, 2003: $17, $0, $0, $0, $32 and $49.
        Year ended December 31, 2002: $452, $0, $1, $0, $95 and $548.

(5)  Many of Corning's  administrative  and staff  functions  are performed on a
     centralized  basis.  Where  practicable,  Corning charges these expenses to
     segments  based upon the extent to which each  business  uses a centralized
     function. Other staff functions, such as corporate finance, human resources
     and legal are allocated to segments, primarily as a percentage of sales.
(6)  Includes  $30  million  and $68  million  in 2003 and  2002,  respectively,
     related  to  impairment  of  long-lived  assets of the  conventional  video

22.  Subsequent Event

Through  March 1, 2004,  we  repurchased  and  retired 25  thousand  zero coupon
convertible  debentures for approximately $19 million in cash resulting in a net
decrease of $20 million to the zero coupon convertible  debenture book value. In
addition, we issued 22 million shares of Corning common stock and $24 million in
cash in  exchange  for 3.5%  convertible  debentures  with a book  value of $213
million at an  effective  conversion  price of $9.675 per share.  As a result of
these transactions, we will record a $23 million pre-tax loss on repurchases and
retirement of debt during the first quarter of 2004.
