                  SCHEDULE XIV - NOTES TO FINANCIAL STATEMENTS

     Instructions: The space below is provided for important notes regarding the
financial  statements  or any account  thereof.  Furnish  particulars  as to any
significant  contingent  assets or liabilities  existing at the end of the year.
Notes  relating to financial  statements  shown  elsewhere in this report may be
indicated here by reference.

1.   Summary of Significant Accounting Policies

Effective  January 1, 1996  Central and South  West  Services, Inc.  (Company or
CSWS) adopted the Federal Energy Regulatory  Commission (FERC) Uniform System of
Accounts. Prior to 1996, the Company followed the Uniform System of Accounts for
Mutual Service  Companies and  Subsidiary  Service  Companies  prescribed by the
Securities and Exchange Commission.  The Company, as a member of the Central and
South West System (CSW System or CSW),  performs,  at cost, various  accounting,
engineering,  tax, legal,  financial,  electronic data  processing,  centralized
economic  dispatching of electric  power,  and other services for the CSW System
companies.

Depreciation
For financial  reporting  purposes,  provisions for depreciation of property are
computed by the Company using the straight-line method,  generally at individual
rates  applied  to the  various  classes  of  depreciable  property.  The annual
composite rates averaged 9.57% for 1999 and 9.27% for 1998.

Federal Income Taxes
The Company, together with other members of the CSW System, files a consolidated
federal income tax return and  participates in a tax sharing  agreement with the
other members of the CSW System. The provision for deferred federal income taxes
resulted  principally  from the tax  deductions  under  accelerated  methods  of
depreciation,  as provided by federal income tax laws,  being greater than these
expenses for book purposes.

2.  Benefit Plans

Cash Balance and Non-qualified Pension Plans
CSW maintains a tax  qualified,  non-contributory  defined  benefit cash balance
pension plan  covering  substantially  all CSW  employees in the United  States.
Under  the  cash  balance  formula,   each  participant  has  an  account,   for
recordkeeping  purposes only, to which credits are allocated annually based on a
percentage of the participant's pay. The applicable  percentage is determined by
age and years of vested  service the  participant  has with the CSW System as of
December 31 of each year.  The fair value of the plan assets are  measured as of
September  30 of each year.  Pension  plan assets  consist  primarily of stocks,
short-term and intermediate-term fixed income investments.

In addition,  the CSW System has a  non-qualified  excess benefit  pension plan.
This plan is  available  to all pension  plan  participants  who are entitled to
recieve a pension benefit from CSW which is in excess of the limitations imposed
on benefits by the Internal Revenue Code through the qualified plan.

according to the provisions of SFAS No.87 and allocate such costs to each of the

disclosure  requirements of SFAS No.87 and SFAS No.88 and have been incorporated
in the following disclosures.

As permitted,  the  amortiztion of any prior service cost is determined  using a
straight-line  amortization  of the cost over the  average  remaining  period of
employees expected to receive benefits under the plan.


CSW Retirement Savings Plan

offered to all full time employees and certain part time employees who meet plan
eligibility  requirements.  Company  contributions  to this  plan  totaled  $4.1
million in 1999 and $3.6 million in 1998.

3.  Financial Instruments

      The following methods and assumptions were used to estimate the fair value
      of each class of  financial  instruments  for which it is  practicable  to
      estimate fair value.

      Cash and temporary cash investments.
      The carrying amount  approximates fair value because of the short maturity
      of those instruments.

      Notes payable to associate companies.
      The carrying amount  approximates fair value because of the short maturity
      of those instruments.




      The estimated fair value of the Company's

4.  Short-Term Financing

The  CSW  System  uses  short-term debt,  primarily  commercial  paper,  to meet
fluctuations  in working capital  requirements  and other interim capital needs.
CSW has established a money pool to coordinate short-term borrowings for certain
subsidiaries.  As of  December  31,  1999 the CSW  System had  revolving  credit
facilities  totaling $1.4 billion to back up its commercial  paper  program.  At
December 31, 1999, CSW had $1.3 billion  outstanding  in short-term  borrowings.
The maximum amount of such short-term  borrowings  outstanding  during the year,
which had a  weighted  average  interest  yield  for the year of 5.5%,  was $1.4
billion  during  December 1999. Of this amount,  $97.1 million  pertained to the
service company.

FOOTNOTES

(1)  Effective  July 1, 1997,  CSW  changed  pension  plan  funding  and benefit
calculation  methods.  The present values of accrued benefits under the existing
pension plan were  converted to a "cash  balance"  pension  plan. As a result of
these changes,  the service company will continue to realize ongoing  reductions
in operating and maintenance  expenses  related to its pension plan. (See Note 2
Benefit Plans for further information related to pensions.)

                  SCHEDULE XVIII - NOTES TO STATEMENT OF INCOME



Instructions:  The space below is provided for  important  notes  regarding  the
statement  of income  or any  account  thereof.  Furnish  particulars  as to any
significant  increase in services rendered or expenses incurred during the year.
Notes  relating to financial  statements  shown  elsewhere in this report may be
indicated here by reference.

    The Data Center provides  centralized  computer  services for all CSW System
     companies.  The following  information is provided pursuant to a Securities
     and Exchange Commission data request letter dated May 6, 1983.

    (a)Aggregate Billings by the Data Center
       The operating  costs for the Data Center for the year ended  December 31,
       1999,  were  $7,595,300.  See paragraph (b) for  explanation  of the 1999
       billing procedure.

    (b)Breakdown of Data Center Billings by CRU
       The  actual  1999  costs  for  the  operation  of the  Data  Center  were
       $7,595,300.  Costs of  operation  of the Data Center were charged back to
       the system companies based on their usage of the computer resources. CSWS
       allocates  its  costs  for  computer  services  rendered  to  CSW  System
       companies as follows:

       Computer Resource Unit (CRU) Component Simplification
       CSWS utilizes the CRU, a  measurement  of computer  services  rendered to
       allocate  direct costs to the CSW companies.  The CRU was previously made
       up of forty  components.  CSWS,  on April 1, 1990,  reduced the number of
       components making up the CRU to only three  components:  (a) tape storage
       in terms of tape-days,  which is used to allocate all tape related costs,
       (b) disk  storage in terms of  track-days  which is used to allocate  all
       disk  related  costs,  and (c) CPU seconds  which is used to allocate all
       other  processor  related  usage  costs.  Use of  only  three  components
       simplifies the computer billing process, reduces administrative costs and
       makes the charges to the users clearer and easier to understand.

       Usage Cost Allocation
       Computer usage costs are allocated on the basis of two factors. A "usage"
       portion is allocated  based on the current number of CRUs used reflecting
       incremental  costs of utilizing the three CRU  components.  The remaining
       "base" costs reflect the fixed costs of operating the data center and are
       spread according to the CRU usage of each company.

       The following  page outlines the billing to companies  separated into the
       two components  referenced  above.  It should be noted that one dollar of
       usage cost equals one CRU.
