Item 2.02.  Results of Operations and Financial Condition

Item 8.01.  Voluntary Disclosure of Other Events

On January 1, 2006,  Corning  changed its  measurement of segment profit or loss
for the following items:
..    We removed the net impact of financing  costs,  such as interest expense on
     debt  instruments and interest costs  associated  with benefit plans,  from
     reportable  segments and included  these  amounts in Corporate  unallocated
     expense.
..    We changed  the  allocation  method for taxes to more  closely  reflect the
     company's current tax position.
..    We  removed  the  impact  of  non-cash  stock  compensation   expense  from
     reportable  segments  and  included  this amount in  Corporate  unallocated
     expense.
..    We  removed  the  allocation  of  exploratory  research,   development  and
     engineering expense from the reportable segments and included these amounts
     in Corporate unallocated expense.
..    We  changed  certain  other  expense   allocation   methods  for  Corporate
     functions.

The following provides historical segment  information  reflecting these changes
in the  measurement  of  segment  profit  or loss  for  2005,  2004 and 2003 and
quarterly information for 2005.

Our reportable operating segments follow:

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

The  Environmental  Technologies  reportable  segment is an  aggregation  of our
Automotive and Diesel  operating  segments,  as these two segments share similar
economic  characteristics,  products,  customer types,  production processes and
distribution methods.

All other  operating  segments that do not meet the  quantitative  threshold for
separate reporting have been grouped as "Other Segments."

(3)  Many of Corning's  administrative  and staff  functions  are performed on a

     segments  based upon the extent to which each  business  uses a centralized
     function. Other staff functions, such as corporate finance, human resources
     and legal are allocated to segments, primarily as a percentage of sales.
(4)  Minority  interests  included  the impact of the  following  restructuring,
     impairment, and other charges (credits):
     .    In 2004, gains from the sale of assets of Corning Asahi Video (CAV) in
          excess of assumed  salvage value of $17 million,  and reversals of CAV
          severance reserves of $2 million.
     .    In 2003,  impairment  charges  for  long-lived  assets of CAV and exit
          costs of $57 million.
(5)  Equity in earnings of associated companies, net of impairments includes the
     following restructuring and impairment charges:
     .    In 2004 and 2003, charges of $35 million and $7 million, respectively,
          to impair equity method investments in the Telecommunications  segment
          to their estimated fair value.
     .    In 2005 and 2003,  $106  million  and $66  million,  respectively,  to
          reflect our share of Samsung  Corning  Co.,  Ltd.'s  asset  impairment
          charges.
(6)  Segment  assets  include  inventory,  accounts  receivable,   property  and
     associated equity companies and cost investments.

(2)  Equity in earnings of associated companies, net of impairments represents
     equity in earnings of Dow Corning Corporation which includes the following
     items:
     .    In 2005,  a gain of $11  million  which  represents  our  share of Dow
          Corning's gain on the issuance of subsidiary stock.
     .    In 2004,  charges of $21  million  which  represents  our share of Dow
          Corning's charges related to restructuring  actions and adjustments to
          interest liabilities recorded on its emergence from bankruptcy.
(3)  As part of Corning's  asbestos  settlement  arrangement to be  incorporated
     into the Pittsburgh Corning Corporation  reorganization  plan, Corning will
     contribute,  when the  reorganization  plan becomes  effective,  25 million
     shares of Corning  common  stock to a trust.  This  portion of the asbestos
     liability  requires  adjustment  based upon  movements in Corning's  common
     stock  price  prior to  contribution  of the shares to the trust.  In 2005,
     2004, and 2003, Corning recorded a charge of $197 million, $33 million, and
     $115  million,  respectively,  to reflect the movement in Corning's  common
     stock price in each year.  In 2003,  Corning also recorded a charge of $298
     million  to  reflect  the  initial  liability  based  on the  terms  of the
     settlement agreement.
(4)  Other corporate items include the tax impact of the unallocated amounts and
     the following significant items:
     .    In   2005,   an   impairment   charge   of   $25   million   for   the
          other-than-temporary  decline in our  investment  in Avanex  below its
          cost basis;  a loss of $16 million  associated  with the redemption or
          retirement  of debt;  a net $443 million  charge to tax expense  which
          included a $525 million  increase to our valuation  allowance  against
          deferred tax assets  resulting from our conclusion that the sale of an
          appreciated  asset no longer met the criteria  established by SFAS No.
          109,  "Accounting  for Income  Taxes"  (SFAS No. 109) for a viable tax
          planning  strategy  offset by an $82  million  credit  to tax  expense
          primarily related to the tax impact of eliminating the minimum pension
          liability associated with our domestic defined benefit plan.
     .    In 2004,  a $937  million  charge  to tax  expense  as a result of the
          company's  decision  to  provide  a  valuation   allowance  against  a
          significant  portion  of its  deferred  tax  assets  and a loss of $36
          million  associated  with the  retirement  of  significant  portion of
          Corning's long-term debt.

     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.

(1)  Net financing costs include interest expense, interest income, and interest
     costs and investment gains associated with benefit plans.
(2)  Equity in earnings of associated companies,  net of impairments  represents
     equity in earnings of Dow Corning  Corporation which includes a gain of $11
     million in the first  quarter which  represents  our share of Dow Corning's
     gain on the issuance of subsidiary stock.
(3)  As part of Corning's  asbestos  settlement  arrangement to be  incorporated
     into the Pittsburgh Corning Corporation  reorganization  plan, Corning will
     contribute,  when the  reorganization  plan becomes  effective,  25 million
     shares of Corning  common  stock to a trust.  This  portion of the asbestos
     liability requires  adjustment based upon quarterly  movements in Corning's
     common stock price prior to contribution of the shares to the trust.
(4)  Other corporate items include the tax impact of the unallocated amounts and
     the following significant item:
     .    In the fourth  quarter,  a net $443  million  charge to tax expense in
          2005 which  included a $525 million  charge to increase our  valuation
          allowance  against  deferred tax assets  resulting from our conclusion
          that  the sale of an  appreciated  asset no  longer  met the  criteria
          established by SFAS No. 109 for a viable tax planning  strategy offset
          by an $82 million credit to tax expense  primarily  related to the tax
          impact of eliminating  the minimum pension  liability  associated with
          our domestic defined benefit plan.
