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 $1,794,000 in 2001 and $(4,389,014) in 2000.

       d.  Leases

       Payments made by the Corporation in connection with operating leases are
       charged to expense incurred. No capitalized leases existed in 2001.

       e.  Account Numbers

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

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 total $62,595,332 as of December 31, 2001, 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 their 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.

h.   Restructuring Activities

     For the year ended December 31, 2001, liabilities were recorded for
     termination benefits related to the Operational Excellence program of the
     Energy Distribution Group and other cost reduction programs. NiSource
     Corprate Services' portion expensed in 2001 was $2,087,912 for severance
     and $167,990 for job placement.
