                      For the Year Ended December 31, 2003


                                  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

                 a.  Property, Plant and Equipment and Related Depreciation

                 Property, Plant and Equipment is stated at historical cost.
                 Depreciation is provided on a composite straight-line basis
                 using the average of depreciable property at the beginning and
                 end of each year.

                 b.  Income Taxes

                 The Corporation provides deferred taxes with respect to timing
                 differences in the recognition of revenues and expenses for tax
                 and accounting purposes. The major difference results from
                 using accelerated depreciation for tax purposes. The
                 Corporation is included in the Consolidated Federal Income Tax
                 Return filed for NiSource, Inc.

                 c.  Pension Costs

                 The Corporation participates in the NiSource, Inc. Pension Plan
                 and the Retirement Income Plan of the Columbia Energy Group.
                 These are trusteed noncontributory pension plans which, with
                 certain exceptions, cover all regular employees. NiSource
                 Corporate Services Company, Inc.'s portion was $7,992,000 in
                 2003 and $2,915,000 in 2002.

                 d.  Leases

                 Payments made by the Corporation in connection with operating
                 leases are charged to expense incurred. No capitalized leases
                 existed in 2003.

                 e.  Account Numbers

                 The Corporation uses certain FERC accounts which do not match
                 existing SEC accounts; therefore, the year-end balances of the
                 following FERC accounts were reclassified to a corresponding
                 SEC account.

                          NOTES TO FINANCIAL STATEMENTS


f. Post-Retirement Benefits Other Than Pensions


   During 1991, the System adopted SFAS No. 106, Employer's Accounting for
   Post-Retirement Benefits Other Than Pensions, retroactive to January 1, 1991.
   The Corporation has elected to record and defer the full amount of its
   estimated accumulated post-retirement obligations other than pensions. These
   obligations $33,830,038 as of December 31, 2003, and represent the actuarial
   present value of the post-retirement benefits to be paid to current employees
   and retirees based on services rendered.

g. System Money Pool

   The Parent Company and its subsidiaries participate in the System Money Pool
   (Pool) which is administered by the Corporation on behalf of the
   participants.

   Participants invest their excess funds to the Pool. Short-term financing
   requirements of participants, with the exception of the Parent Company, are
   satisfied by advances from the Pool. Excess funds in the Pool are invested by
   the Corporation on a short-term basis on behalf of the depositors.

   Participants depositing funds in the Pool share in the interest earned on
   these investments plus interest paid to the Pool by borrowers on a basis
   proportionate to its investment in the Pool. Participants borrowing from the
   Pool pay interest at the rate equivalent to the composite rate on short-term
   transactions of the Pool. Participants may withdraw their investments in the
   Pool at any time. Borrowings from the Pool are payable on demand, and may be
   prepaid at any time without premium or penalty.

                          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

                  indicated here by reference.

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

Salary and wage expense was lower $21.9 million in 2003 when compared to 2002.
In 2002, salary and wage expense was higher $10.1 million as a result of
severance charges relating to a corporate restructuring initiative. Salary and
wage expense was also lower in 2003 due to a decrease in stock based
compensation and bonus payout of $11.1 and $1.7 million respectively.

Outside Services decreased approximately $20 million from 2002 to 2003. Outside
services was lower $14 million in 2003 when compared to 2002 due to a decrease
in Consulting and Legal expenses of $7 million and $7 million respectively.
Other outside services also decreased approximately $6 million in 2003 when
compared to 2002. The decrease in other outside services is primarily due to a
one-time payment to an outside firm in 2002 as a result of a restructuring
initiative.

Benefits expense increased in 2003 by $5.3 million. This increase was primarily
due to increased Retirement Income Plan expense from 2002 to 2003.
