1. Accounting Policies

Business, Utility Operations and Regulation

      The Company is an operating  public  utility  engaged,  together  with its
utility  subsidiaries,  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 Public  Utilities  Commission of the State of Colorado
("CPUC") with respect to its retail  electric and gas operations and the Federal
Energy  Regulatory  Commission  ("FERC") with respect to its wholesale  electric
operations  and  accounting  policies and  practices.  Approximately  90% of the
Company's electric and gas revenues are subject to CPUC  jurisdiction.  Cheyenne
Light, Fuel and Power Company ("Cheyenne") is subject to the jurisdiction of the
Public Service Commission of Wyoming ("WPSC"). WestGas InterState,  Inc. ("WGI")
and Texas-Ohio  Pipeline,  Inc. are subject to the jurisdiction of the FERC. The
gas  marketing,  power  brokering  and other  operations  of e prime,  inc.  and
Texas-Ohio Gas, Inc.  (acquired  September 1, 1996) are not rate regulated.  The
Company  also  invests in  electricity  systems  outside  the  United  States as
discussed  in Note 4. The  Company's  international  investments  are subject to
regulation in the countries in which such investments are made.

      Effective  August 1, 1997,  the Company and  Southwestern  Public  Service
Company  ("SPS")  merged and became  wholly-owned  subsidiaries  of New  Century
Energies,  Inc.  ("NCE"),  which will be a registered  holding company under the
Public Utility Holding Company Act of 1935. This  transaction has been accounted
for as a pooling of interests  for  accounting  purposes.  After  effecting  the
Merger,  NCE will own the following direct  subsidiaries:  PSCo, SPS,  Cheyenne,
WGI,  New  Century  Services,  Inc.,  and NC  Enterprises,  Inc.  PSCo  owns the
following subsidiaries:  PS Colorado Credit Corporation, PSR Investments,  Inc.,
1480 Welton, Inc., Fuel Resources Development Co., a dissolved corporation,  and
New Century  International,  Inc.,  which was  established in 1997 in connection
with  the   acquisition   of  Yorkshire   Electricity   Group  plc   ("Yorkshire
Electricity").  NC Enterprises,  Inc., an  intermediate  holding company of NCE,
owns the following  subsidiaries:  Quixx  Corporation  and its  subsidiaries,  e
prime,  inc.  and its  subsidiaries,  Utility  Engineering  Corporation  and its
subsidiaries and Natural Fuels Corporation.  The transfer of subsidiaries is not
expected to have a material impact on the Company's financial position,  results
of operations or cash flows (see Note 2).

      Regulatory Assets and Liabilities

      The  Company  and  its  regulated  subsidiaries  prepare  their  financial
statements  in  accordance   with  the  provisions  of  Statement  of  Financial
Accounting  Standards No. 71 -  "Accounting  for the Effects of Certain Types of
Regulation"  ("SFAS 71").  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
Statement  of  Financial  Accounting  Standards  No.  121  "Accounting  for  the
Impairment of Long-Lived  Assets and Long-Lived  Assets to Be Disposed Of" 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 regulatory assets of the Company and its regulated  subsidiaries as of
June 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 flow.

      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  Statement  of  Financial
Accounting  Standards  No.  112  -  "Employers'  Accounting  for  Postemployment
Benefits" ("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 and Cheyenne's  tariffs contain 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  Energy Cost Adjustment  ("ECA") with
an Incentive  Cost  Adjustment  ("ICA"),  which allows for a 50%/50%  sharing of
certain  fuel and  energy  cost  increases  or  decreases  among  customers  and
shareholders.  As of June 30,  1997,  the cost  sharing  allowed  under  the ICA
reduced cost recoveries by approximately $2 million.

      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.

      Miscellaneous Income and Deductions - net

      Miscellaneous  income  and  deductions  - net  includes  items  which  are
non-operating  in nature or, in general,  are not  considered in the  ratemaking
process. Such items include, among other things, merger and business integration
costs (see Note 2), contributions,  gains and losses on the sale of property and
certain litigation,  executive severance and other accruals. Individually, these
amounts did not have a material impact on the Company's  consolidated results of
operations.

Statements of Cash Flows - Non-cash Transactions

      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  referenced above were non-cash  financing  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. Merger

      In August 1995,  the Company,  SPS, a New Mexico  corporation,  and NCE, a
Delaware  corporation,  entered  into an  Agreement  and Plan of  Reorganization
("Merger  Agreement")  providing  for  a  business  combination  as  peer  firms
involving the Company and SPS in a tax-free "merger of equals"  transaction (the
"Merger"). Effective August 1, 1997, following receipt of all required state and
Federal regulatory approvals, the Company and SPS merged and became wholly-owned
subsidiaries of NCE. 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.  Based on the  outstanding
common  stock of the Company and SPS at August 1, 1997,  the Merger  resulted in
the common  shareholders  of the Company  owning 63% of the common equity of NCE
and the common  shareholders  of SPS  owning  37% of the  common  equity of NCE.
Effective with the Merger, the utility and certain  non-utility  subsidiaries of
the Company were transferred by a declaration of a dividend of the subsidiaries'
stock, at net book value, to NCE. NCE then made a capital  contribution of those
non-utilities' stock, at net book value, to NC Enterprises, Inc.

* NCE's net  income is net of  dividend  requirements  on  preferred  stock of

      It is management's intention that NCE begin realizing certain savings upon
the  consummation  of the Merger and,  accordingly,  costs  associated  with the
Merger and the transition  planning and implementation  have negatively impacted
earnings during 1997. The Company recognized approximately $5.2 and $1.4 million
of  costs  during  the  second  quarter  of 1997  and  1996,  respectively,  and
approximately  $6.4 and $4.2 million of costs  associated with the Merger during
the first six months of 1997 and 1996, respectively.

3. 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,  the WPSC 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:

             over 15%                  100%              0%;

     - the  termination of the Qualifying  Facilities  Capacity Cost  Adjustment
     ("QFCCA") earnings test which was to become effective on October 1, 1996;
     
     - 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,  Qualifying Facility ("QF") and
     decommissioning costs;
     - 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 penalties  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.  The CPUC opened a new docket on March 31,
     1997 to address the  implementation  of a reward  structure for performance
     above certain standards.

        The freeze in base  electric  rates does not  prohibit  the Company from
filing a  general  rate case or deny any party the  opportunity  to  initiate  a
complaint or rate proceeding.

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. On June 9, 1997,  the Company filed its
appeal in Denver District Court  concerning the CPUC's decision which disallowed
the recovery of certain  postemployment  benefit  costs under SFAS 112 (see Note
1), imputed  anticipated merger related cost savings related to the gas business
and weather normalization methodology.

      The  Company  filed a rate  case  with  the  FERC on  December  29,  1995,
requesting a slight  overall  rate  increase  (less than 1%) from its  wholesale
electric  customers.  This filing,  among other things,  requested  approval for
recovery  of  Other  Postretirement   Employee  Benefits  ("OPEB")  costs  under
Statement of Financial Accounting Standards No. 106 - "Employers' Accounting for
Postretirement Benefits Other Than Pensions", postemployment benefit costs under
SFAS  112  and  new  depreciation  rates  based  on the  Company's  most  recent
depreciation  study.  Settlement  agreements  were  reached with all parties and
filed with the FERC, which, overall, resulted in a slight decrease in rates. The
FERC approved the settlement agreements on June 13, 1997, subject to the Company
making certain compliance filings.

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 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.

                                       10


             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                 (Continued)

      The CPUC has had an on-going docket to review and prescribe a standardized
GCA process to determine  the prudence of gas  commodity  and pipeline  delivery
service costs incurred by gas utilities.  Other issues  addressed in this docket
included  whether the GCA should be maintained  in its present form,  altered or
eliminated.  On May 7, 1997,  the CPUC issued a final order,  which provides for
the current GCA to be maintained and the adoption of certain standardized filing
and gas purchase reporting requirements.

Environmental Issues

Environmental Site Cleanup

      As described below, the Company has been or is currently involved with the
clean-up of contamination from 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 U.S. Environmental Protection Agency ("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  supersedeas  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. 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 intends to
pursue  recovery from one carrier.  Additionally,  the Company intends to appeal
the decision to the Colorado Court of Appeals.

      The Ramp Industries  disposal  facility,  located in Denver,  Colorado has
been designated by the EPA as a Superfund  hazardous  substance site pursuant to
CERCLA.  On November 29,  1995,  the Company  received  from the EPA a Notice of
Potential  Liability  and Request for  Information  related to such site and the
Company has responded to

                                       11


             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                 (Continued)

this request.  The EPA is conducting an  investigation  of the  contamination at
this site and is in the  process of  identifying  the nature and  quantities  of
hazardous  wastes  delivered to,  processed and currently  stored at the site by
PRPs. In April,  1997, the EPA informed the Company and more than 700 other PRPs
(as well as the  public)  that it plans to  thermally  treat and dispose of some
Ramp  hazardous  substances  off-site.  The EPA estimates the total cost of this
site remedy to be approximately $10 million.  The Company's  insurance  carriers
have been notified of the EPA investigation.

      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  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 and Pollution Control

      Under the Clean Air Act Amendments of 1990,  coal burning power plants are
required to reduce sulfur dioxide  ("SO2") and nitrogen oxide ("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,
and does not anticipate that these  regulations  will  significantly  impact its
consolidated financial position, results of operations or cash flow.

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 scheduled for late August 1997.
The Company does not believe that its  potential  liability or the future impact
of this litigation on plant  operations  will have a material  adverse impact on
the Company's  consolidated  results of operations,  financial  position or cash
flows.  This  litigation is similar to the Hayden  Station  complaint  which was
settled in 1996 as 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
the Fort St. Vrain Nuclear  Generating Station ("Fort St. Vrain") and to proceed
with the defueling and  decommissioning  of the reactor.  While the defueling of
the  reactor  to the  Independent  Spent Fuel  Storage  Facility  ("ISFSI")  was
completed in June 1992, several issues related to the ultimate  storage/disposal
of Fort St. Vrain's spent nuclear fuel remained unresolved.

                                       12


             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                 (Continued)

      On February 9, 1996,  the Company  and the  Department  of Energy  ("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 Nuclear  Regulatory  Commission
("NRC") to transfer the title of the ISFSI.  This  request is being  reviewed by
the NRC and the Company anticipates approval in the second half of 1997.

      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 June 30,
1997,  a  remaining  $5 million  defueling  and  decommissioning  liability  was
reflected on the consolidated condensed balance sheet. The Company 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 will be 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 flow.

      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, as well as interest and attorney fees. Such amounts,
including  estimated  interest and attorney fees were accrued  during the second
quarter of 1997.  The Company has appealed  this  decision and believes that the
amended severance plan is lawful and enforceable.

      During 1996, complaints were filed by seventeen  plaintiffs,  allegedly on
behalf  of all  non-managerial,  non-clerical  women in the  Company's  regional
facilities. The complaints assert that the Company has engaged in a company-wide
pattern and practice of sexual  discrimination,  including sexual harassment and
retaliation.  During July 1997, the Company  resolved all issues related to this
matter and accrued all related estimated costs.

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.  The Company  believes that the
ultimate  outcome of the lawsuit will not have a material  adverse impact on the
Company's results of operations, financial position or cash flow.

4.  Acquisition and Divestiture of Investments

Acquisition of Yorkshire Electricity

      On February 24, 1997,  Yorkshire Power Group Ltd.  ("Yorkshire  Power"), a
50/50 joint venture  between the Company and American  Electric  Power  ("AEP"),
announced  that  they had  reached  agreement  with the  board of  directors  of
Yorkshire  Electricity,  a United Kingdom regional  electricity  company, on the
terms of a recommended  cash tender offer for all of the  outstanding  and to be
issued ordinary shares of Yorkshire Electricity. On April 1, 1997, the effective
date of this  acquisition,  Yorkshire Power (through  Yorkshire  Holdings plc, a
wholly-owned  subsidiary equally owned by the Company and AEP) declared the cash
tender offer wholly  unconditional  in all  respects.  Substantially  all of the
Yorkshire Electricity stock has been acquired.

      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.

      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.  Summarized
income statement information for the period from the date of acquisition,  April
1, 1997, to June 30, 1997 for Yorkshire Power is as follows (millions):

    Operating revenues              $ 438.5
    Operating income                   52.1
    Net income                          8.2
    Company's equity in the earnings
        of Yorkshire Power              4.1

      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 date of acquisition was April 1, 1997 and accordingly the pro forma
adjustments  for the six months  ended June 30, 1997 reflect the amounts for the
three months ended March 31, 1997. 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 the 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

                                       14

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 six months  ending  June 30,  1997 and June 30,
1996, $1.6342/ and $1.5276/, respectively.

     preparation for deregulation.

      On July 2, 1997, the United  Kingdom's Labour Party proposed a budget that
includes a windfall profits tax on certain  privatized  business  entities.  The
windfall  profits tax  liability for  Yorkshire  Electricity  is estimated to be
approximately $222 million (135 million pounds sterling). The tax was enacted in
late  July of 1997 and will be  payable  in two  installments  with the first in
December 1997 and the second  installment a year later.  The Company's  share of
the proposed tax is estimated to be approximately $111 million. The net earnings
effect on the Company of the  proposed tax is  currently  being  assessed and is
expected to be recorded in the third quarter of 1997.

5.  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
June 30, 1997 and December 31, 1996, and the results of operations for the three
and six months  ended  June 30,  1997 and 1996 and cash flows for the six months
ended June 30, 1997 and 1996. The consolidated  condensed financial  information
and notes thereto should be read in conjunction with the

                                       15

1996,  1995 and 1994 included in the  Company's  1996 Annual Report on Form 10-K
filed with the Securities and Exchange Commission.

      Because  of  seasonal  and other  factors,  including  the  reorganization
associated  with the Merger  discussed in Note 2, the results of operations  for
the three  months and six months  ended June 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 June
30, 1997, and the related  consolidated  condensed  statements of income for the
three  and six  month  periods  ended  June 30,  1997 and 1996 and  consolidated
condensed statements of cash flows for the six month periods ended June 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

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

Earnings

      Earnings  per share were $0.42 for the second  quarter of 1997 as compared
to $0.49 for the  second  quarter of 1996.  The lower  earnings  were  primarily
attributable  to  relatively  flat  retail  electric  sales and an  increase  in
expenses,  including those  associated with the Merger,  which became  effective
August  1,  1997.  The  recent  acquisition  of  a  50%  interest  in  Yorkshire
Electricity  positively  impacted the Company's  earnings by  approximately  two
cents per share after borrowing costs. In the third quarter of 1997, the Company
expects to record the effects of the Yorkshire  Electricity's  windfall  profits
tax (see  discussion in Note 4.  Acquisition  and  Divestiture  of Investments -
Acquisition of Yorkshire Electricity in Item 1.
FINANCIAL STATEMENTS).

      Electric margin  decreased in the second quarter of 1997, when compared to
the  first  quarter  of  1996,  primarily  due to  the  retail  rate  reductions
(approximately  $4.3 million)  implemented in October 1996 and February 1997 and
the  effect  of the  ICA  which  resulted  from  the  settlement  of the  Merger
proceedings in Colorado (see Note 3.  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 have  contributed  to increased  operating  revenues,
however, the margin on such sales is minimal.


                                       18


      The Company and Cheyenne have 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.  As of June 30,
1997,  this  sharing  has  reduced  cost  recoveries  allowed  under  the ICA by
approximately $2 million.

      Fuel used in generation  expense increased  approximately  6.3% during the
second 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  slightly during the second quarter of
1997 as compared to the same quarter in 1996.  Costs incurred in connection with
the increased  non-regulated  power marketing sales were partially offset by the
lower costs of economy purchases from other utilities to meet customer demand.

      Gas sales margin increased in the second quarter of 1997, when compared to
the second quarter of 1996,  primarily due to higher rates effective February 1,
1997,  resulting from the Company's  1996 rate case. In addition,  gas marketing
activities by non-regulated  subsidiaries  favorably contributed to the increase
in gas sales margin.

      Gas  transportation,  gathering,  processing and other revenues  increased
$0.5  million  during the second  quarter of 1997,  when  compared to the second
quarter of 1996,  primarily due to an increase in transportation rates effective
February 1, 1997, resulting from the Company's 1996 rate case.

      The  Company and  Cheyenne  have in place GCA  mechanisms  for natural gas
sales, which recognize the majority of the effects of changes in the cost of gas
purchased  for resale and adjust  revenues to reflect  such changes in cost on a
timely  basis.  As a result,  the  changes  in  revenues  associated  with these
mechanisms  during


                                       19


the second  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

      Other operating and maintenance expenses increased $1.2 million during the
second quarter of 1997, as compared to the same period in 1996, primarily due to
increased  expenses  at  e  prime  and  subsidiaries  and  advertising  expenses
associated  with the new logo,  offset,  in part, by lower labor costs and other
general reductions resulting from the Company's cost containment efforts.

      Depreciation and amortization expense increased $4.1 million in the second
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 second  quarter of 1997,  as compared
to the same period in 1996, is primarily due to lower pretax income, the effects
of  recognizing  certain  foreign  tax  credits  associated  with the  Yorkshire
Electricity  investment  and  the  tax  effects  of  lower  1997  non-deductible
environmental and Merger costs.

      Miscellaneous income and deductions - net decreased $4.8 million primarily
due to additional 1997 accruals for estimated  legal and other costs  associated
with various employee  lawsuits and higher 1997 Merger and business  integration
costs. These additional costs were offset, in part, by the recognition of equity
earnings associated with the Company's investment in Yorkshire Electricity ($4.1
million) and interest income on temporary cash  investments of the proceeds from
the borrowings  subsequently used for the investment made in acquiring Yorkshire
Electricity   (see  Note  4.   Acquisition  and  Divestiture  of  Investments  -
Acquisition of Yorkshire Electricity in Item 1. FINANCIAL STATEMENTS).

      Interest expense increased $8.7 million during the second 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  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.

Six Months Ended June 30, 1997 Compared to the Six Months Ended June 30, 1996

Earnings

      Earnings per share were $1.34 for the first six months of 1997 as compared
to $1.46 for the  first  six  months of 1996.  While  earnings  were  positively
impacted by continued  customer growth  contributing to increased electric sales
and gas deliveries as well as the Company's cost containment efforts,  there was
a decline in the 1997  year-to-date  earnings  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 3.  Commitments and
Contingencies - Fort St. Vrain in Item 1. FINANCIAL STATEMENTS) offset, in part,
by the recognition of various non-recurring expense items during that period. In
the third  quarter of 1997,  the  Company  expects to record the  effects of the
Yorkshire  Electricity's  windfall  profits  tax  (see  discussion  in  Note  4.
Acquisition   and   Divestiture   of  Investments  -  Acquisition  of  Yorkshire
Electricity in Item 1. FINANCIAL STATEMENTS).

      Electric  margin  increased in the first six months of 1997, when compared
to the first six months of 1996,  primarily  due to higher  electric  Kwh retail
sales  resulting from customer  growth offset,  in part, by lower fuel costs and
rate reductions  effective  October 1, 1996 and February 1, 1997  (approximately
$7.3 million),  which resulted from the settlement of the Merger  proceedings in
Colorado (see Note 3. 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 have contributed to increased  operating revenues,  however,  the
margin on such sales is minimal.

      The Company and Cheyenne have 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.  This sharing reduced
recoveries of energy costs,  allowed under the ICA, by  approximately $2 million
during the first six months of 1997, as compared to the same period in 1996.

      Fuel used in generation  expense  increased  slightly during the first six
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 six months of 1997.


                                       21


      Purchased power expense increased $2.2 million during the first six months
of 1997 as  compared to the same period in 1996.  Costs  incurred in  connection
with the increased  non-regulated power marketing sales were partially offset by
the lower  costs of economy  purchases  from other  utilities  to meet  customer
demand.

      Gas sales margin  increased in the first six months of 1997, when compared
to the first six months of 1996,  primarily  due to an increase in the Company's
base revenues  associated with the higher rates which became 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 six 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
$1.7 million during the first six months of 1997, when compared to the first six
months of 1996,  primarily  due to an  increase  in  transportation  rates which
became effective  February 1, 1997,  resulting from the Company's 1996 rate case
and a slight 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 and  Cheyenne  have in place GCA  mechanisms  for natural gas
sales, which recognize the majority of the effects of changes in the cost of gas
purchased  for resale and adjust  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 six 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 $10.9 million during
the six months  ended June 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 increased
operating costs at e prime and  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,  as did costs incurred  during 1996 associated with the settlement
of certain  environmental  issues  related to the operations of the Hayden Steam
Electric Generation Station.

      Depreciation and amortization expense increased $10.1 million in the first
six 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 six months of 1997, as compared
to the same period in 1996, is primarily due to lower pre-tax income, lower 1997
non-deductible  environmental  and Merger  costs and the prior year  accrual for
additional tax liabilities.

      Miscellaneous income and deductions - net decreased $1.1 million primarily
due to additional 1997 accruals for estimated  legal and other costs  associated
with various employee  lawsuits and higher 1997 Merger and business  integration
costs. These additional costs were offset, in part, by the recognition of equity
earnings associated with the Company's investment in Yorkshire Electricity ($4.1
million) and interest income on temporary cash  investments of the proceeds from
the borrowings  subsequently used for the investment made in acquiring Yorkshire
Electricity   (see  Note  4.   Acquisition  and  Divestiture  of  Investments  -
Acquisition of Yorkshire Electricity in Item 1. FINANCIAL STATEMENTS).

      Interest  expense  increased  $5.5 million  during the first six months of
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.

Financial Position

      Accounts payable decreased  approximately $83 million at June 30, 1997, as
compared to December 31, 1996,  primarily due to the impact of seasonally  lower
gas purchases. This also contributed to the reduction in accounts receivable.

Commitments and Contingencies

      Issues  relating to  regulatory,  environmental  and  employee  litigation
matters are discussed in Note 3 Commitments and  Contingencies and the estimated
windfall  tax  liability  for  Yorkshire  Electricity  is  discussed  in Note 4.
Acquisition  and  Divestiture of  Investments  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.

Common Stock Dividend

      In March 1997,  the Board of  Directors  ("the  Board")  approved a common
stock dividend at the rate of $0.525 per share. In anticipation of the effective
date of the Merger,  in June 1997 the Board approved a partial  dividend payable
to  shareholders  of the Company  covering the period July 12, 1997 through July
31, 1997,  the day prior to the Merger  effective  date,  based on the quarterly
dividend  rate of $0.525,  but  prorated  for the number of days in the  interim
period  (approximately $0.115 per share). During the second quarter of 1996, the
Company  increased  the

                                       23


quarterly  common  stock  dividend of $0.51 per share to $0.525 per share.  As a
result of the consummation of the Merger,  effective  August 1, 1997,  dividends
will be paid to NCE as the holder of all of the Company's common stock.

      Cash provided by operating activities decreased in the first six 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 six months ended
June 30, 1997,  when  compared to the same period in 1996,  primarily due to the
Company's  acquisition of Yorkshire  Electricity in April 1997 for approximately
$360 million.

Net cash provided by (used in) financing 
  activities (in millions) ..............     $388.9      $(56.6)      $445.5

      Cash provided by financing  activities  increased  (indicating  that there
were more borrowings) in the first six 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  4.
Acquisition   and   Divestiture   of  Investments  -  Acquisition  of  Yorkshire
Electricity in Item 1. FINANCIAL STATEMENTS.

OTHER MATTERS

      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
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.
