1. Accounting Policies

Merger

      Effective  August 1, 1997,  following  receipt of all required state and
Federal  regulatory  approvals,  the  Company  and SPS  merged  in a  tax-free
"merger of equals"  transaction and became  wholly-owned  subsidiaries of NCE,
which is a registered  holding  company  under PUHCA.  NCE owns the  following
direct   subsidiaries:   the  Company,   SPS,   Cheyenne,   WGI,  NCS  and  NC
Enterprises.  Each outstanding  share of Company common stock was canceled and
converted  into the right to receive  one share of NCE  common  stock and each
outstanding  share of SPS common  stock was canceled  and  converted  into the
right to receive 0.95 of one share of NCE common  stock with this  transaction
being accounted for as a pooling of interest for accounting purposes.

      Effective  with the Merger,  Cheyenne,  WGI, e prime,  and Natural Fuels
were  transferred by a declaration of a dividend of the  subsidiaries'  stock,
at net book  value,  aggregating  approximately  $49.9  million,  to NCE.  NCE
subsequently  made a capital  contribution  of the e prime and  Natural  Fuels
common stock, at net book value,  aggregating  approximately $29.5 million, to
NC Enterprises.  The accompanying  consolidated  financial  statements reflect
the financial  position,  results of  operations  and cash flows for Cheyenne,
WGI, e prime and Natural  Fuels for all periods that  include  months prior to
August 1, 1997.  The  transfer of these  subsidiaries  did not have a material
impact on the  Company's  financial  position,  results of  operations or cash
flows.

Business, Utility Operations and Regulation

      The Company is an operating  public utility  engaged  principally in the
generation, purchase,  transmission,  distribution and sale of electricity and
in the  purchase,  transmission,  distribution,  sale  and  transportation  of
natural  gas.  The  Company is subject  to the  jurisdiction  of the CPUC with
respect to its retail  electric and gas  operations  and the FERC with respect
to its wholesale  electric  operations and accounting  policies and practices.
Effective  August  1,  1997,  the  Company  owns the  following  subsidiaries:
PSCCC,  PSRI, 1480 Welton,  Inc., Fuelco and New Century  International,  Inc.
which was  established in 1997 in connection with the acquisition of Yorkshire
Electricity.  The Company  invests in electricity  systems  outside the United
States as discussed in Note 3. The  Company's  international  investments  are
subject to regulation in the countries in which such investments are made.

      Regulatory Assets and Liabilities

      The Company  prepares its financial  statements  in accordance  with the
provisions of SFAS 71, as amended.  SFAS 71  recognizes  that  accounting  for
rate  regulated  enterprises  should  reflect  the  relationship  of costs and
revenues  introduced  by  rate  regulation.  A  regulated  utility  may  defer
recognition  of a cost (a  regulatory  asset) or  recognize an  obligation  (a
regulatory  liability) if it is probable that, through the ratemaking process,
there will be a corresponding  increase or decrease in revenues. On January 1,
1996, the Company  adopted SFAS 121, which imposes  stricter  criteria for the
continued  recognition of regulatory  assets on the balance sheet by requiring
that such assets be probable of future  recovery at each  balance  sheet date.
The  adoption of this  statement in 1996 and the  application  during 1997 did
not have a material impact on the Company's  results of operations,  financial
position or cash flows. The following  regulatory  assets are reflected in the
Company's  consolidated  condensed  balance  sheets  (the  December  31,  1996
amounts include Cheyenne and WGI):

      The  regulatory  assets of the  Company  as of  September  30,  1997 are
reflected  in rates  charged to  customers  over the  recovery  periods  noted
above.  The Company believes it will continue to be subject to rate regulation
to the extent  necessary to recover these assets.  In the event that a portion
of the Company's  operations is no longer subject to the provisions of SFAS 71
as a result of a change in  regulation  or the  effects  of  competition,  the
Company could be required to write-off related  regulatory  assets,  determine
any impairment to other assets resulting from  deregulation and write-down any
impaired  assets to their  estimated  fair value,  which could have a material
adverse effect on the Company's results of operations,  financial  position or
cash flows.

      On January 27,  1997,  the CPUC issued its order on the  Company's  1996
gas rate case.  The CPUC  allowed  recovery of  postemployment  benefit  costs
associated  with its gas  operations  on an accrual  basis  under SFAS 112 and
denied  amortization  of  the  approximately  $8.7  million  regulatory  asset
recognized  upon the adoption of SFAS 112. On June 9, 1997,  the Company filed
its appeal in Denver  District  Court.  The Company is assessing the impact of
this decision on the future  recovery of the electric  jurisdictional  portion
of postemployment  benefit costs totaling  approximately $13.8 million. If the
appeal to the Denver District Court is  unsuccessful,  the Company will appeal
this  issue to the  Colorado  Supreme  Court.  The  Company  believes  it will
ultimately  be  successful  in  its  appeals.  If  appeals  are  unsuccessful,
including  pursuing the  establishment  of an  alternative  form of regulatory
recovery, these amounts will be written off.

      Recovered/Recoverable Purchased Gas and Electric Energy Costs - Net

      The Company's  tariff  contains  clauses which allow recovery of certain
purchased  gas and electric  energy costs in excess of the level of such costs
included in base rates.  Currently,  these cost adjustment tariffs are revised
periodically,  as prescribed by the appropriate  regulatory agencies,  for any
difference  between  the total  amount  collected  under the  clauses  and the
recoverable  costs  incurred.  The  cumulative  effects  are  recognized  as a
current asset or liability  until adjusted by refunds or  collections  through
future billings to customers.  The CPUC order related to the Company's  merger
rate filing  modified and replaced the Company's ECA with an ICA, which allows
for a 50%/50%  sharing of certain fuel and energy cost  increases or decreases
among customers and shareholders.

      Other Property

      Property,  plant and equipment includes  approximately $18.4 million and
$25.4 million,  respectively, for costs associated with the engineering design
of a planned  future  Pawnee 2  generating  station and certain  water

rights located in southeastern  Colorado,  also obtained for a future generating
station.  The  Company  is  earning a return on these  investments  based on the
Company's weighted average cost of debt and preferred stock in accordance with a
CPUC rate order.

Statements of Cash Flows - Non-cash Transactions

      Prior  to the  Merger,  shares  of  common  stock  (250,058  in 1997 and
274,934  in  1996),  valued  at the  market  price  on the  date  of  issuance
(approximately  $10 million in 1997 and 1996),  were issued to the  Employees'
Savings and Stock  Ownership  Plan of Public  Service  Company of Colorado and
Participating   Subsidiary  Companies.  The  estimated  issuance  values  were
recognized in other operating expenses during the respective  preceding years.
Shares of common  stock  (6,470 in 1996),  valued at the  market  price on the
date of issuance  ($0.2  million in 1996),  were issued to certain  executives
pursuant to the applicable provisions of the executive compensation plans.

      The  stock  issuances  and  the  dividend  of  subsidiaries'   stock  in
connection  with the  Merger  discussed  above  were  non-cash  financing  and
investing  activities  and are not  reflected  in the  consolidated  condensed
statements of cash flows.

General

      See Note 1. of the Notes to  Consolidated  Financial  Statements  in the
Company's  1996  Annual  Report on Form 10-K for a  summary  of the  Company's
significant  accounting  policies.   Certain  prior  year  amounts  have  been
reclassified to conform to the current year's presentation.

2. Commitments and Contingencies

Regulatory Matters

1995 Merger Rate Filings

      In connection  with the Merger with SPS, in November  1995,  the Company
filed  comprehensive  proposals with the CPUC and the FERC to obtain  approval
of the Merger and the associated  comprehensive proposals from such regulatory
agencies.

      On November  29,  1996,  and as modified on January 15,  1997,  the CPUC
issued  a  written  decision  approving  the  Merger  as  well  as  the  major
provisions of a stipulation and agreement entered into among the Company,  the
CPUC  Staff,   the  Colorado   Office  of  Consumer   Counsel   ("OCC"),   and
substantially  all  other  parties.  The  decision  establishes  a  five  year
performance  based regulatory plan and acknowledges  that the Merger is in the
public interest.  The major provisions of the decision include:

      - a $6 million electric rate reduction,  which was instituted  October 1,
      1996,  followed by an additional  $12 million  electric  rate  reduction
      effective with the implementation of new gas rates on February 1, 1997;

      - an  annual  electric  department  earnings  test  with the  sharing  of
      earnings  in excess of an 11%  return on equity for the  calendar  years
      1997-2001 as follows:

          Electric Department      Sharing of Excess Earnings
           Return on Equity      Customers        Shareholders
           ----------------      ---------        ------------
               11-12%               65%              35%
               12-14%               50%              50%
               14-15%               35%              65%
             over 15%              100%              0%;

       The Company has established an estimated  customer refund obligation of
      approximately  $7.4 million in connection  with the electric  department
      sharing of  earnings  in excess of 11% return on equity for the  results
      of  operations  through  September  30,  1997.  It  is  expected,  at  a
      minimum,  that a similar amount will be recognized in the fourth quarter
      of 1997;
      - a freeze in base  electric  rates for the period  through  December 31,
      2001,   with  the  flexibility  to  make  certain  other  rate  changes,
      including  those  necessary  to allow for the  recovery  of DSM,  QF and
      decommissioning  costs.  The  freeze  in base  electric  rates  does not
      prohibit  the Company  from filing a general rate case or deny any other
      party the opportunity to initiate a complaint or rate proceeding;
      - a  replacement  of the Company's ECA with an ICA to allow for a 50%/50%
      sharing of certain fuel and energy cost  increases  or  decreases  among
      customers and shareholders; and
      - the  implementation of a Quality of Service Plan ("QSP") which provides
      for bill  credits  totaling up to $5 million in year one and  increasing
      to $11  million in year five,  if the Company  does not achieve  certain
      performance   measures  relating  to  electric   reliability,   customer
      complaints  and telephone  response to  inquiries.  On October 15, 1997,
      the CPUC  issued  an order  addressing  the  implementation  of a Reward
      Mechanism in the QSP which  provides up to $3 million of annual  rewards
      if  the  Company  achieves  certain  performance  measures  relating  to
      electric   reliability.   Based  on  performance   measurements  through
      September  30,  1997,  the  Company  believes  the QSP  will  not have a
      material  adverse  effect  on  the  Company's   results  of  operations,
      financial position or cash flows.

      In November  1997, in  connection  with the annual  electric  department
earnings test discussed  above, the CPUC held a hearing to review the prudence
of merger costs, allocation  methodologies of merger costs, and the ratemaking
treatment  of a  transmission  agreement  with a wholesale  customer.  A final
decision on these issues is expected in early 1998.

Rate Cases

      On June 5,  1996,  the  Company  filed a retail  rate case with the CPUC
requesting an annual increase in its  jurisdictional  gas department  revenues
of  approximately  $34 million.  In early 1997,  the CPUC  approved an overall
increase  of  approximately  $18  million  with an 11.25%  return  on  equity,
effective  February 1, 1997 and as modified on May 15,  1997.  The Company has
appealed the CPUC's decision with the Denver  District Court which  disallowed
the recovery of certain  postemployment benefit costs under SFAS 112 (see Note
1  Accounting  Policies  -  Business,  Utility  Operations  and  Regulation  -
Regulatory  Assets and  Liabilities)  and imputed  anticipated  merger related
cost savings related to the gas business.

Electric and Gas Cost Adjustment Mechanisms

      During 1994 and 1995, the CPUC conducted  several  proceedings to review
issues  related to the ECA. The CPUC opened a docket to review whether the ECA
should be  maintained  in its  present  form,  altered or  eliminated,  and on
January  8, 1996,  combined  this  docket  with the  merger  docket  discussed
above.  The CPUC decision on the Merger

                                       9

                                 (Continued)

modified  and replaced  the ECA with an ICA.  The ICA,  which  became  effective
October 1, 1996,  allows for a 50%/50%  sharing of certain  fuel and energy cost
increases and decreases  among customers and  shareholders.  Management does not
believe  that the  sharing  requirements  under  the ICA  mechanism  will have a
significant impact on the Company's results of operations, financial position or
cash flows.

Environmental Issues

Environmental Site Cleanup

      As described below,  the Company has been or is currently  involved with
the clean-up of certain hazardous substances.  In all situations,  the Company
is  pursuing  or  intends to pursue  insurance  claims  and  believes  it will
recover some portion of these costs through such claims.  Additionally,  where
applicable,  the Company  intends to pursue  recovery  from other  Potentially
Responsible  Parties  ("PRPs").  To the extent  such costs are not  recovered,
the  Company  currently  believes  it is  probable  that  such  costs  will be
recovered  through the rate  regulatory  process.  To the extent any costs are
not recovered  through the options listed above, the Company would be required
to recognize an expense for such unrecoverable amounts.

      Under  the  Comprehensive   Environmental  Response,   Compensation  and
Liability Act  ("CERCLA"),  the EPA identified,  and a Phase II  environmental
assessment has revealed,  low level,  widespread  contamination from hazardous
substances  at the Barter  Metals  Company  ("Barter")  properties  located in
central  Denver.  For an estimated 30 years,  the Company sold scrap metal and
electrical  equipment to Barter for  reprocessing.  The Company has  completed
the  cleanup  of this  site  at a cost of  approximately  $9  million  and has
received  responses  from  the  Colorado   Department  of  Public  Health  and
Environment  ("CDPHE")  indicating that no further action is required  related
to these  properties.  On January 3, 1996, in a lawsuit by the Company against
its insurance  providers,  the Denver District Court entered final judgment in
favor of the Company in the amount of $5.6 million for certain  cleanup  costs
at Barter.  Several  appeals and cross  appeals  have been filed by one of the
insurance  providers  and the Company in the  Colorado  Court of Appeals.  The
insurance  provider has posted  supersedes bonds in the amount of $9.7 million
($7.7 million  attributable  to the Barter  judgment).  On July 10, 1997,  the
Colorado  Court of Appeals  overturned  the  previously  awarded  $7.7 million
judgment on the basis that the jury had not been  properly  instructed  by the
Judge  regarding  a narrow  issue  associated  with  some of the  policies.  A
retrial is expected.  Previously,  the Company had received certain  insurance
settlement  proceeds  from  other  insurance  providers  for  Barter and other
contaminated  sites and a portion of those funds  remains to be  allocated  to
this site by the trial  court.  The Company  also plans to appeal the Colorado
Court of Appeals  decision to the Colorado  Supreme  Court.  In addition,  the
Company expects to recoup additional  expenditures  beyond insurance  proceeds
through the sale of the Barter  property and from other PRPs.  In August 1996,
the Company  filed a lawsuit  against  four PRPs  seeking  recovery of certain
Barter related costs.

      Polychlorinated   biphenyl   ("PCB")  presence  was  identified  in  the
basement of an  historic  office  building  located in  downtown  Denver.  The
Company was negotiating  the future cleanup with the current owners;  however,
on October 5, 1993,  the owners  filed a civil  action  against the Company in
the  Denver  District   Court.   The  action  alleged  that  the  Company  was
responsible  for the PCB releases and  additionally  claimed  other damages in
unspecified  amounts.  On August 8, 1994, the Denver  District Court entered a
judgment  approving a $5.3 million offer of settlement between the Company and
the building owners  resolving all claims.  In December 1995,  complaints were
filed by the Company against all applicable  insurance  carriers in the Denver
District  Court.  On June 30, 1997,  the Denver  District Court ruled in favor
of the insurance  carriers on summary judgment motions  addressing late notice
and other  issues.  The  Company is pursuing  recovery  from one  carrier.  On
August  27,  1997,  the  Company  filed an  appeal  of the  decision  with the
Colorado Court of Appeals.

      In addition to these sites,  the Company has  identified  several  sites
where  cleanup  of  hazardous  substances  may be  required.  While  potential
liability and settlement costs are still under  investigation and negotiation,
the Company  believes  that the  resolution  of these  matters will not have a
material  adverse effect on its financial  position,  results of 

                                       10

                                 (Continued)

operations  or cash flows.  The Company  fully intends to pursue the recovery of
all significant costs incurred for such projects through insurance claims and/or
the rate regulatory process.

Environmental Matters Related to Air Quality

      Under the Clean Air Act  Amendments  of 1990,  coal burning power plants
are required to reduce SO2 and NOx  emissions to  specified  levels  through a
phased  approach.  The  Company's  facilities  must  comply  with the Phase II
requirements  which  will be  effective  in the year  2000.  Currently,  these
regulations  permit  compliance  with sulfur dioxide  emission  limitations by
using  S02  allowances  allocated  to  plants  by the  EPA,  using  allowances
generated  by reducing  emissions at existing  plants and by using  allowances
purchased  from  other  companies.  The  Company  expects to meet the Phase II
emission  standards  placed on SO2 through the  combination  of: a) use of low
sulfur  coal,  b) the  operation of air quality  control  equipment on certain
generation  facilities,  and c) allowances issued by the EPA. The Company will
be  required  to  modify  certain  boilers  by the  year  2000 to  reduce  NOx
emissions in order to comply with Phase II  requirements.  The estimated Phase
II  costs  for  future  plant   modifications  to  meet  NOx  requirements  is
approximately  $13 million.  The Company is studying its options to reduce NOx
and SO2  emissions.  PSCo  has  recently  announced  its  intention  to  spend
approximately  $211  million in the Denver and  Boulder  metro area to further
reduce such emissions.

Craig Steam Electric Generating Station

      On October 9, 1996,  a  conservation  organization  filed a complaint in
the U.S.  District  Court  pursuant to provisions of the Federal Clean Air Act
(the "Act")  against the joint owners of the Craig Steam  Electric  Generating
Station.  Tri-State  Generation  and  Transmission  Association,  Inc.  is the
operator  of the Craig  station  and the Company  owns an  undivided  interest
(acquired  in  April  1992)  in  each of two  units  at the  station  totaling
approximately  9.7%. The plaintiff  alleged that: 1) the station  exceeded the
20% opacity  limitations in excess of 14,000 six minute  intervals  during the
period  extending from the first quarter of 1991 through the second quarter of
1996,  and 2) the owners failed to operate the station in a manner  consistent
with good air pollution control  practices.  The complaint seeks,  among other
things,  civil monetary  penalties and injunctive relief. The Act provides for
penalties of up to $25,000 per day per  violation,  but the level of penalties
imposed in any particular  instance is discretionary.  A pre-trial  conference
has been  rescheduled  for  December  1997.  Management  does not believe that
this  potential  liability or the future  impact of this  litigation  on plant
operations will have a material  adverse impact on the Company's  consolidated
financial  position,  results of operations  or cash flows.  The issues raised
in this  litigation  are  similar to the Hayden  Station  complaint  which was
settled in 1996 and  disclosed  in the  Company's  1996 Annual  Report on Form
10-K.

Fort St. Vrain

      In 1989,  the Company  announced its decision to end nuclear  operations
at Fort St. Vrain and to proceed with the  defueling  and  decommissioning  of
the reactor.  While the defueling of the reactor to the ISFSI was completed in
June 1992,  several  issues related to the ultimate  storage/disposal  of Fort
St. Vrain's spent nuclear fuel remained unresolved.

      On February 9, 1996,  the Company and the DOE entered  into an agreement
resolving all the defueling  issues.  As part of this  agreement,  the Company
has agreed to the  following:  1) the DOE assumed title to the fuel  currently
stored in the  ISFSI,  2) the DOE will  assume  title to the ISFSI and will be
responsible for the future defueling and  decommissioning of the facility,  3)
the DOE agreed to pay the Company $16  million  for the  settlement  of claims
associated  with  the  ISFSI,  4)  ISFSI  operating  and  maintenance   costs,
including   licensing   fees  and  other   regulatory   costs,   will  be  the
responsibility  of the DOE, and 5) the Company  provided to the DOE a full and
complete release of claims against the DOE resolving all contractual  disputes
related  to  storage/disposal  of  Fort  St.  Vrain  spent  nuclear  fuel.  On
December  17,  1996,  the DOE  submitted a request to the NRC to transfer  the
title of the ISFSI.  This request is being reviewed by the NRC and the Company
anticipates approval no earlier than mid-1998.

             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                 (Continued)

      On March 22,  1996,  the  Company  and the  decommissioning  contractors
announced  that the physical  decommissioning  activities at the facility were
completed.  On August 5,  1997,  the NRC  approved  the  Company's  request to
terminate the Part 50 operating  license.  This concludes the  decommissioning
activities  and the  facilities  and  site are  suitable  to be  released  for
unrestricted  use. Under the  Price-Anderson  Act, the Company remains subject
to potential  assessments levied in response to any nuclear incidents prior to
early 1994,  as disclosed in the  Company's  1996 Annual  Report on Form 10-K.
At September 30, 1997, a remaining $2.4 million defueling and  decommissioning
liability  was  reflected  on  the  consolidated   condensed   balance  sheet.
Management  believes this remaining  decommissioning  liability is adequate to
finalize the payment of all related obligations.

      As a result of the DOE  settlement,  coupled  with a complete  review of
expected remaining  decommissioning costs and establishment of the anticipated
refund to  customers,  pre-tax  earnings  for the first  quarter  of 1996 were
positively  impacted by  approximately  $16 million.  In  accordance  with the
1991 CPUC approval to recover certain  decommissioning  costs, 50% of any cash
amounts  received from the DOE as part of a settlement,  net of costs incurred
by the  Company,  including  legal  fees,  is to be  refunded  or  credited to
customers.  The Company  established  an $8 million  refund  liability  in the
first quarter of 1996.  During the first quarter of 1997,  such obligation was
reduced by  approximately  $1.1  million  after  amounts to be  refunded  were
finally  determined and approved by the CPUC.  Such amounts are being refunded
over a three year period.

Employee Litigation

      Several employee  lawsuits have been filed against the Company involving
alleged  discrimination,  sexual  harassment or worker's  compensation  issues
which have arisen  during the normal course of business.  Also,  lawsuits have
been filed against the Company alleging breach of certain  fiduciary duties to
employees.  The  plaintiffs  lawsuits  are in  various  stages  of  litigation
and/or appeal(s) including settlement discussions,  with the appropriate state
judicial courts.  The Company intends to contest,  or is actively  contesting,
all such lawsuits,  and management believes that the ultimate outcome will not
have a  material  adverse  impact  on the  Company's  results  of  operations,
financial position or cash flows.

      During 1996, ninety former  Information  Technology and Systems ("IT&S")
employees  filed a lawsuit  against the Company.  The  complaint  alleges that
the  Company  unfairly  amended  its  severance  plan  in  connection  with  a
restructuring  in late 1994 to exclude the IT&S  function/positions  that were
outsourced to IBM,  effective  February 1, 1995. On June 16, 1997,  the Denver
District  Court  issued a decision in favor of the former IT&S  employees  and
awarded  approximately  $1.6 million in severance  costs and, in a judgment on
October 10, 1997 the former IT&S employees were awarded  interest and attorney
fees as well, making the total judgment against the Company $2.1 million.  The
Company  has been  informed  that  approximately  150  additional  former IT&S
employees  have filed an  identical  claim,  although the Company has not been
served with this  lawsuit.  Such  amounts,  including  estimated  interest and
attorney fees were accrued  during the second and third  quarters of 1997. The
Company has appealed the  decision  and  believes  that the amended  severance
plan is lawful and enforceable.

      Certain  employees   terminated  as  part  of  the  Company's  1991/1992
organizational  analysis  asserted breach of contract and promissory  estoppel
with  respect to job  security  and breach of the  covenant  of good faith and
fair dealing.  Of the 21 actions filed,  the trial court directed  verdicts in
favor of the  Company  in 19 cases.  A jury  entered  verdicts  adverse to the
Company in two cases  which were  subsequently  appealed  by the  Company.  On
February  6, 1997,  the  Colorado  Court of Appeals  issued a decision  on all
issues in favor of the  Company  and on April 3, 1997 the  employees  appealed
the decision of the Colorado  Court of Appeals to the Colorado  Supreme Court.
In October  1997,  the Colorado  Supreme Court denied the petition for appeal,
effectively ending this lawsuit.

3.  Acquisition of Yorkshire Electricity and U.K. Windfall Profits Tax

      On April 1, 1997,  Yorkshire  Power (through  Yorkshire  Holdings plc, a
wholly-owned  subsidiary  equally  owned  by the  Company  and  AEP)  acquired
substantially   all  of  the   outstanding   ordinary   shares  of   Yorkshire
Electricity,  a United Kingdom regional electricity  company.  Yorkshire Power
is a 50/50 joint  venture  between

the Company and AEP. The Company  accounts for its investment in Yorkshire Power
using the equity method.  Yorkshire Power's results of operations  includes 100%
of Yorkshire  Electricity's  results since April 1, 1997.  The Company's  equity
earnings in Yorkshire Power is 50%, the same as its ownership share.

      The total  consideration  paid by Yorkshire Power was approximately $2.4
billion  (1.5  billion  pounds  sterling).  The  acquisition  was  financed by
Yorkshire  Power through a  combination  of  approximately  25% equity and 75%
debt,   including   the   assumption   of  the  existing   debt  of  Yorkshire
Electricity.  The funds for the  acquisition  were obtained from the Company's
and AEP's  investment in Yorkshire  Power of  approximately  $360 million (220
million pounds sterling) each, with the remainder  obtained by Yorkshire Power
through  the  issuance of  non-recourse  debt.  The Company  funded its entire
equity  investment in Yorkshire  Power through $250 million of publicly issued
secured   medium-term   notes  with   varying   maturities   and  drawings  of
approximately  $110 million on its short-term  lines of credit pursuant to its
short-term credit agreement with Bank of America, as agent.

      In July 1997,  the U.K.  government  enacted a windfall  profits  tax on
certain   privatized   business   entities   which  will  be  payable  in  two
installments  with the first in  December  1997 and the second  installment  a
year later.  The  windfall  profits tax was a  retroactive  adjustment  to the
privatization  value based on  post-privatization  profits  during the 1992 to
1995 period.  During the third quarter of 1997,  Yorkshire  Power  recorded an
extraordinary  charge  of  approximately  $221  million  (135  million  pounds
sterling)  for this windfall  profits tax. The Company's  share of this tax is
approximately $110.6 million.

      Summarized  income  statement  information  for the period April 1, 1997
(date of acquisition) to September 30, 1997 is presented below (in millions):

      The pro forma  financial  information  presented  below assumes that the
acquisition  of  Yorkshire  Power  was  acquired  on the  first  day  of  each
respective  period.  The pro forma adjustments  include  recognition of equity
in the  estimated  earnings of Yorkshire  Power,  an  adjustment  for interest
expense on debt  associated  with the Company's  investment in Yorkshire Power
and related  income  taxes.  The  estimated  earnings of  Yorkshire  Power was
based on prior  historical  earnings of  Yorkshire  Electricity,  prior to its
acquisition  by  Yorkshire  Power,  adjusted  for  the  estimated  effects  of
purchase  accounting  (including the amortization of goodwill),  conversion to
United States generally accepted  accounting  principles,  interest expense on
debt issued by Yorkshire  Power  associated  with the  acquisition and related
income taxes.  Sales of electricity are affected by seasonal  weather patterns
and, therefore, the results of Yorkshire Power/Yorkshire  Electricity will not
be distributed  evenly during the year.  Equity in earnings of Yorkshire Power
has been  converted  at the average  exchange  rates for the nine months ended
September 30, 1997 and September 30, 1996,  $1.6318/pound  and  $1.5367/pound,
respectively.

4.  Management's Representations

      In the opinion of the Company, the accompanying  unaudited  consolidated
condensed financial statements include all adjustments  necessary for the fair
presentation of the financial  position of the Company and its subsidiaries at
September 30, 1997 and December 31, 1996,  and the results of  operations  for
the three and nine  months  ended  September  30, 1997 and 1996 and cash flows
for the nine  months  ended  September  30,  1997 and 1996.  The  consolidated
condensed   financial   information  and  notes  thereto  should  be  read  in
conjunction  with the  consolidated  financial  statements  and  notes for the
years ended  December 31, 1996,  1995 and 1994 included in the Company's  1996
Annual Report on Form 10-K.

      Because of seasonal and other factors, including the reorganization
associated with the Merger, the results of operations for the three months
and nine months ended September 30, 1997 should not be taken as an indication
of earnings for all or any part of the balance of the year.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


TO PUBLIC SERVICE COMPANY OF COLORADO

We have  reviewed the  accompanying  consolidated  condensed  balance sheet of
Public Service Company of Colorado (a Colorado  corporation)  and subsidiaries
as of September 30, 1997, and the related  consolidated  condensed  statements
of income for the three and nine month  periods  ended  September 30, 1997 and
1996 and  consolidated  condensed  statements of cash flows for the nine month
periods ended September 30, 1997 and 1996. These financial  statements are the
responsibility of the Company's management.

We  conducted  our review in  accordance  with  standards  established  by the
American  Institute  of  Certified  Public  Accountants.  A review of  interim
financial  information consists principally of applying analytical  procedures
to financial data and making  inquiries of persons  responsible  for financial
and  accounting  matters.  It is  substantially  less in  scope  than an audit
conducted in  accordance  with  generally  accepted  auditing  standards,  the
objective of which is the  expression  of an opinion  regarding  the financial
statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our  review,  we are not  aware of any  material  modifications  that
should be made to the  financial  statements  referred to above for them to be
in conformity with generally accepted accounting principles.

We have previously  audited,  in accordance with generally  accepted  auditing
standards,  the  consolidated  balance  sheet of  Public  Service  Company  of
Colorado  and  subsidiaries  as of December 31, 1996 (not  presented  herein),
and, in our report  dated  February 24,  1997,  we  expressed  an  unqualified
opinion on that  statement.  In our opinion,  the information set forth in the
accompanying  consolidated condensed balance sheet as of December 31, 1996, is
fairly  stated,  in all  material  respects,  in relation to the  consolidated
balance sheet from which it has been derived.

Item 2.  Management's  Discussion  and  Analysis of  Financial  Condition  and
Results of Operations

Merger

      Effective  August 1, 1997,  following  receipt of all required state and
Federal  regulatory  approvals,  the  Company  and SPS  merged  in a  tax-free
"merger of equals"  transaction and became  wholly-owned  subsidiaries of NCE,
which is a registered  holding  company  under  PUCHA.  This  transaction  was
accounted for as a pooling of interests  for  accounting  purposes.  Effective
with the Merger,  Cheyenne, WGI, e prime and Natural Fuels were transferred by
a declaration  of a dividend of the  subsidiaries'  stock,  at net book value,
aggregating  approximately  $49.9  million,  to NCE. NCE  subsequently  made a
capital  contribution  of the e prime and Natural Fuels common  stock,  at net
book value,  aggregating  approximately $29.5 million, to NC Enterprises.  See
Note 1  Accounting  Policies  - Merger  in Item 1.  Financial  Statements  for
additional  discussion  regarding the Company,  the Merger and the transfer of
Cheyenne, WGI, e prime and Natural Fuels.

      The consolidated  condensed  statements of income and cash flows reflect
the results of operations of Cheyenne,  WGI, e prime and Natural Fuels through
July 31, 1997.  Where relevant,  additional  information has been presented to
discuss the impact of the transfer of these subsidiaries.

Three  Months  Ended  September  30, 1997  Compared to the Three  Months Ended
September 30, 1996

Earnings

      The Company  recognized a loss of $76.0 million for the third quarter of
1997 as compared to net  earnings  of $36.3  million for the third  quarter of
1996.  The net  loss  was  primarily  attributable  to the  recognition  of an
extraordinary  item  related to the  one-time  U.K.  windfall  profits  tax of
approximately   $110.6   million  by  Yorkshire   Electricity,   a  50%  owned
investment.  Excluding  the  impact of this  extraordinary  charge,  quarterly
earnings  decreased  approximately  5% from the previous  year. An increase in
merger  and  business  integration  costs  resulting  from the  August 1, 1997
closing of the Merger and electric rate  decreases  instituted in October 1996
and February 1997  contributed to the lower  earnings.  Ongoing  operations of
Yorkshire Electricity,  however, positively impacted the Company's earnings by
approximately $14.1 million after borrowing costs, net of income taxes.

*  Percentages are calculated using unrounded amounts

      Electric  margin  decreased in the third quarter of 1997,  when compared
to the third  quarter of 1996,  primarily  due to the retail  rate  reductions
(approximately  $4.8 million)  implemented  in October 1996 and February 1997,
the  recognition of an estimated  customer  refund  obligation  (approximately
$7.4 million) in connection with the earnings  sharing in excess of 11% return
on equity and the effect of the ICA which  resulted from the settlement of the
Merger  proceedings in Colorado (see Note 2.  Commitments and  Contingencies -
Regulatory  Matters  in  Item  1.  Financial  Statements).   Higher  wholesale
electric sales also contributed to increased operating revenues,  however, the
margin on such sales is minimal.

      The Company has cost adjustment  mechanisms which recognize the majority
of the  effects of  changes in fuel used in  generation  and  purchased  power
costs and allow  recovery of such costs on a timely basis.  In its decision on
the  Merger,  the CPUC  replaced  the  Company's  ECA  with an ICA,  effective
October  1, 1996,  which  allows  for a 50%/50%  sharing  of certain  fuel and
energy cost increases and decreases  among  customers and  shareholders.  (see
Note  2.  Commitments  and  Contingencies  -  Regulatory  Matters  in  Item 1.
Financial Statements).

      Fuel used in generation expense increased  approximately 3.8% during the
third  quarter  of 1997,  as  compared  to the same  quarter  in 1996,  due to
increased  generation levels at the Company's power plants offset, in part, by
lower coal supply costs.

      Purchased  power  expense  increased  3.4%  during the third  quarter of
1997,  as compared to the same quarter in 1996,  primarily due to purchases to
meet increased wholesale  requirements and other customer demands,  offset, in
part, by the recognition of only one month of Cheyenne expenses.

      Gas sales margin  decreased  slightly in the third quarter of 1997, when
compared to the third  quarter of 1996,  primarily  due to a 6.2%  decrease in
sales,  offset, in part, by higher rates effective February 1, 1997, resulting
from the Company's 1996 rate case.

      Gas transportation,  gathering,  processing and other revenues increased
$0.6  million  during the third  quarter of 1997,  when  compared to the third
quarter  of 1996,  primarily  due to an  increase  in  deliveries  and  higher
transportation  rates effective February 1, 1997, resulting from the Company's
1996 rate case.

      The Company has in place a GCA  mechanism  for natural gas sales,  which
recognizes  the  majority  of  the  effects  of  changes  in the  cost  of gas
purchased  for resale and adjusts  revenues to reflect such changes in cost on
a timely basis.  As a result,  the changes in revenues  associated  with these
mechanisms  during the third  quarters  of 1997 and 1996 had little  impact on
net income.  However,  the  fluctuations in gas sales impact the amount of gas
the  Company  must  purchase  and,  therefore,  along with the  increases  and
decreases in the per-unit cost of gas, affect total gas purchased for resale.

Non-Fuel Operating Expenses

      Depreciation  and  amortization  expense  increased  $3.4 million in the
third quarter of 1997,  as compared to the same period in 1996,  primarily due
to the  depreciation  of property  additions  and the higher  amortization  of
software costs.

      The decrease in income taxes for the third  quarter of 1997, as compared
to the  same  period  in  1996,  is  primarily  due to  lower  pretax  income.
Additional  income tax expense  was  recognized  in the current  period due to
higher 1997 non-deductible merger and executive severance costs.

      Other income and  deductions  increased  $15.5 million  primarily due to
the  recognition of equity  earnings in Yorkshire  Power ($17.3  million),  of
which  approximately  $10  million  is  related  to the  change  in  the  U.K.
corporate  income  tax  rate  from  33% to 31%.  See  Note 3.  Acquisition  of
Yorkshire  Electricity  and U.K.  Windfall  Profits  Tax in Item 1.  Financial
Statements.  This  increase  was  offset,  in part,  by  increased  merger and
business integration costs  (approximately $6.0 million),  including executive
severance costs,  resulting from the closing of the Merger effective August 1,
1997.  While  costs  associated  with  the  Merger,  transition  planning  and
implementation  have  negatively  impacted  earnings  during  1997  and  1996,
management  anticipates  that  future  operating  results  will  benefit  from
synergies resulting from the Merger.

      Interest  charges  increased  $10.1 million  during the third quarter of
1997, when compared to the same quarter in 1996,  primarily due to interest on
borrowings  utilized  to  finance  capital  expenditures  and the  April

                                       18
<PAGE>

1997  acquisition  of  Yorkshire  Electricity.  These  borrowings  included  the
issuance  of $75 million and $250  million of  medium-term  notes in January and
March 1997, respectively.

Nine  Months  Ended  September  30, 1997  Compared  to the Nine  Months  Ended

Earnings

      Earnings  were  $11.6  million  for the  first  nine  months  of 1997 as
compared to $129.3  million  during the same period in 1996.  The  significant
decrease was primarily  attributable  to the  recognition of an  extraordinary
item  related to the  one-time  U.K.  windfall  profits  tax of  approximately
$110.6  million by Yorkshire  Power,  a 50% owned  investment.  While earnings
were  positively   impacted  by  continued  customer  growth  contributing  to
increased  electric  and gas sales as well as the equity  earnings  in ongoing
operations  at Yorkshire  Electricity,  income before the  extraordinary  item
decreased  $7.3  million for the nine months  ended in 1997 as compared to the
same period in 1996.  This decline was  attributable  to the favorable  impact
in 1996 of the February 9, 1996  settlement  agreement  with the DOE resolving
all spent  nuclear  fuel  storage and  disposal  issues at Fort St. Vrain (see
Note 2.  Commitments  and  Contingencies - Fort St. Vrain in Item 1. Financial
Statements),  the  recognition of higher 1997 merger and business  integration
costs and higher interest costs.

      Electric  margin  decreased  in the  first  nine  months  of 1997,  when
compared  to  the  first  nine  months  of  1996.   Although  customer  growth
contributed  to higher  electric  Kwh retail  sales,  the decrease in electric
margin was primarily  attributable  to retail rate  reductions  implemented in
October  1996  and  February  1997  (approximately   $12.1  million)  and  the
recognition of an estimated  customer refund  obligation  (approximately  $7.4

                                       19
<PAGE>

million) in  connection  with the earnings  sharing in excess of 11% return on
equity  which  resulted  from the  settlement  of the  Merger  proceedings  in
Colorado (see Note 2.  Commitments and  Contingencies - Regulatory  Matters in
Item 1. Financial  Statements).  Power marketing  activities by  non-regulated
subsidiaries  initiated  in the third  quarter  of 1996 and  higher  wholesale
electric sales also contributed to increased operating revenues,  however, the
margin on such sales is minimal.

      The Company has cost adjustment  mechanisms which recognize the majority
of the  effects of  changes in fuel used in  generation  and  purchased  power
costs and allow  recovery of such costs on a timely  basis.  As  discussed  in
Note  1.  Accounting  Policies  -  Recovered/Recoverable   Purchased  Gas  and
Electric Energy Costs - Net in Item 1. Financial  Statements,  in its decision
on the Merger,  the CPUC  replaced the  Company's  ECA with an ICA,  effective
October  1, 1996,  which  allows  for a 50%/50%  sharing  of certain  fuel and
energy cost increases and decreases among customers and shareholders.

      Fuel used in  generation  expense  increased  slightly  during the first
nine months of 1997, as compared to the same period in 1996,  due to increased
generation  levels at the  Company's  power plants  offset,  in part, by lower
coal supply costs in the first nine months of 1997.

      Purchased  power expense also increased  slightly  during the first nine
months of 1997,  as compared to the same period in 1996,  due to  purchases to
meet wholesale  requirements  and other customer  demands and increased  power
marketing  activities,  offset,  in part,  by the  recognition  of only  seven
months of Cheyenne costs in 1997 verses nine months in 1996.

      Gas sales  margin  increased  in the  first  nine  months of 1997,  when
compared  to the first nine  months of 1996,  primarily  due to an increase in
the  Company's  base  revenues  associated  with the  higher  rates  effective
February 1, 1997,  resulting  from the Company's 1996 rate case. Gas marketing
activities  by  non-regulated   subsidiaries   favorably  contributed  to  the
increase  in gas sales  margin.  Gas costs were  higher  during the first nine

                                       20
<PAGE>

months of 1997,  as compared to the same period of 1996, as a result of higher
gas prices incurred through the winter heating season.

      Gas transportation,  gathering,  processing and other revenues increased
$2.3 million during the first nine months of 1997,  when compared to the first
nine months of 1996,  primarily  due to an increase  in  transportation  rates
effective February 1, 1997,  resulting from the Company's 1996 rate case and a
3.8%  increase  in  transportation   deliveries.   The  higher  transportation
deliveries  are  attributable  to the shifting of various  Company  commercial
sales  customers  to  firm  transportation   customers.   Historically,   this
shifting  has not had an impact on gas margin and is not  expected  to have an
impact in the future.

      The Company has in place a GCA  mechanism  for natural gas sales,  which
recognizes  the  majority  of  the  effects  of  changes  in the  cost  of gas
purchased  for resale and adjusts  revenues to reflect such changes in cost on
a timely basis.  As a result,  the changes in revenues  associated  with these
mechanisms  during the first nine months of 1997 and 1996 had little impact on
net income.  However,  the  fluctuations in gas sales impact the amount of gas
the  Company  must  purchase  and,  therefore,  along with the  increases  and
decreases in the per-unit cost of gas, affect total gas purchased for resale.

Non-Fuel Operating Expenses

      Other operating and maintenance  expenses increased $11.2 million during
the nine months ended  September 30, 1997, when compared to the same period in
1996,  primarily due to the favorable  impact on 1996 earnings of the February
9, 1996  settlement  agreement  with the DOE  resolving all spent nuclear fuel
storage and disposal  issues at Fort St. Vrain  (approximately  $16  million).
In addition,  higher electric  production and distribution  maintenance  costs
and higher operating costs at non-regulated  subsidiaries  negatively impacted
current  year  results.  However,  lower  employee  benefit  costs  and  other
general  reductions  resulting  from the Company's  cost  containment  efforts
favorably impacted current year results.

      Depreciation  and  amortization  expense  increased $13.5 million in the
first nine months of 1997,  as compared to the same period in 1996,  primarily
due to the depreciation of property  additions and the higher  amortization of
software costs.

      The  decrease  in income  taxes for the first  nine  months of 1997,  as
compared to the same period in 1996, is primarily due to lower pre-tax  income
and  the  prior  year  accrual  for  additional  tax   liabilities.   However,
additional  income tax expense was recognized in the current period for higher
non-deductible merger and executive severance costs.

      Other income and deductions  increased  $14.4 million  primarily due the
recognition of equity earnings in Yorkshire  Electricity  ($21.4 million),  of
which  approximately  $10  million  is  related  to the  change  in  the  U.K.
corporate  income  tax  rate  from  33% to 31%  (see  Note 3.  Acquisition  of
Yorkshire  Electricity  and U.K.  Windfall  Profits  Tax in Item 1.  Financial
Statements).  This  increase  was offset,  in part,  by  increased  merger and
business  integration costs,  including executive  severance costs,  resulting
from  the  closing  of the  Merger  effective  August  1,  1997.  While  costs
associated  with the  Merger,  transition  planning  and  implementation  have
negatively  impacted  earnings  during 1997 and 1996,  management  anticipates
that future operating  results will benefit from synergies  resulting from the
Merger.

      Interest  expense  increased  $24.2 million during the nine months ended
September 30, 1997,  when  compared to the same period in 1996,  primarily due
to interest on borrowings  utilized to finance  capital  expenditures  and the
April 1997 acquisition of Yorkshire  Electricity.  These  borrowings  included
the issuance of $75 million and $250 million of  medium-term  notes in January
and March 1997, respectively.

Commitments and Contingencies

      Issues  relating to regulatory and  environmental  matters are discussed
in Note 2  Commitments  and  Contingencies  in Item 1.  Financial  Statements.
These  matters  and the future  resolution  thereof  may impact the  Company's
future results of operations, financial position or cash flows.

     Based on a preliminary analysis, NCE and its subsidiaries expect to incur
costs of  approximately $50-65 million  over the next two years to modify  its
computer  software, hardware and other automated  systems  used in  operations
enabling  proper  data  processing relating  to  the  year  2000  and  beyond.
Approximately  two-thirds of these costs are  expected  to be  incurred  by or
allocated to the Company. The Company continues to evaluate appropriate courses
of  corrective   action, including  the  replacement  of  certain  systems.  A
significant portion of these costs will represent the redeployment of existing
information   technology  resources.   Management does  not  anticipate  these
activities  will  have a  material adverse impact on the  Company's  financial
position, results of operations or cash flows.

      Cash  provided  by  operating  activities  decreased  in the first  nine
months of 1997,  when  compared to the same period in 1996,  primarily  due to
the increase in payments to gas suppliers  resulting from the higher gas costs
in late 1996 and early  1997.  A portion  of these  higher gas costs have been
deferred through the GCA and will be recovered from customers in the future.

      Cash used in  investing  activities  increased  during  the nine  months

due to the  Company's  April 1,  1997  acquisition  of an equity  interest  in
Yorkshire Electricity for approximately $362 million.

Net cash provided by (used in) financing 
    activities (in millions) ...............  $424.1      $ (56.3)      $480.4

      Cash provided by financing activities  increased  (indicating that there
were more  borrowings) in the first nine months of 1997,  when compared to the
same  period in 1996,  primarily  due to the  issuance of $75 million and $250
million of medium  term notes in January  and March  1997,  respectively.  The
proceeds  from the $75  million  financing  were  used to fund  the  Company's
construction  program.  The Company  used the  proceeds  from the $250 million
medium term notes,  together with additional  borrowings of approximately $110
million  on its  short-term  lines  of  credit,  to fund  its  acquisition  of
Yorkshire  Electricity.  See Note 3. Acquisition of Yorkshire  Electricity and
U.K.  Windfall  Profits Tax in Item 1.  Financial  Statements.  As a result of
the  increase in  recoverable  purchased  gas and  electric  energy  costs and
reduced  cash  flows  resulting  from  lower  electric  rates,   coupled  with
increased merger and business  integration costs, the Company has utilized the
proceeds   from   additional   short-term   borrowings   to  finance   ongoing
construction  expenditures.  With the  consummation  of the  Merger  effective
August 1, 1997,  management  anticipates  that  future  operating  results and
related cash flows will benefit from synergies resulting from the Merger.

Electric Utility Industry

      Electric  utilities  have  historically  operated in a highly  regulated
environment  in which they have an obligation to provide  electric  service to
their  customers in return for an  exclusive  franchise  within their  service

  
                                     22

<PAGE>

territory  with an  opportunity  to earn a  regulated  rate  of  return.  This
regulatory  environment  is changing.  The generation  sector has  experienced
competition  from  nonutility  power  producers  and  the  FERC  is  requiring
utilities,  including the Company, to provide wholesale  transmission  service
to others  and may order  electric  utilities  to enlarge  their  transmission
systems to facilitate  transmission  services without  impairing  reliability.
State   regulatory   authorities  are  in  the  process  of  changing  utility
regulations  in response to federal and state  statutory  changes and evolving
markets,   including   consideration   of  providing  open  access  to  retail
customers.  All of the Company's  jurisdictions  continue to evaluate  utility
regulations  with  respect to  competition.  The  Company is unable to predict
what financial  impact or effect the adoption of these proposals would have on
its  operations.  The Merger  between the  Company  and SPS was,  in part,  in
response to these changing conditions.
