GENERAL TERMS AND CONDITIONS

TCRA/EPCA Carrying Charge Calculations

33. CARRYING CHARGE CALCULATIONS

33.1. General. After computing carrying charges on any

deferred account balance that is subject to this

Section, Pipeline will:

A. Compound carrying charges on a calendar quarter

basis; and

B. Debit carrying charges to the deferred account if

the carrying charge base is a debit (positive), and

credit carrying charges to the deferred account if

the carrying charge base is a credit (negative).

33.2. Calculation. To compute carrying charges, Pipeline

will multiply the carrying charge rate by the appropriate

carrying charge base.

A. Carrying charge base. The carrying charge base for

the refund, revenue credits, and billing adjustments

subaccount will be the prior month's ending refund,

revenue credit, and billing adjustment subaccount

balance of Account No. 186, adjusted for any

applicable deferred income taxes recorded and reduced

for any unpaid accruals. The carrying charge base

for any other subaccount of Account No. 186 will be

the prior month's ending balance: (i) reduced for

unpaid accruals; (ii)adjusted for any applicable

deferred income taxes; and (iii) increased or

decreased for exchange transactions and trans-

portation imbalance cost adjustments; and (iv)

adjusted for the difference, if any, between the

rate used for storage gas, and the rate that would be

effective for storage gas if a rolling weighted

average inventory costing methodology had been used.

B. Carrying charge rate. Pipeline will compute a monthly

carrying charge rate by stating on an annual basis the

applicable calendar quarterly rate prescribed in Section

154.501(d)(1) of the Commission's regulations, dividing

the annual rate by 365, or 366 if a leap year, to compute

a daily interest rate, expressed to the nearest one

ten-thousandth of one percent; and multiplying the

daily interest rate by the number of days in the applicable

month, to compute a monthly rate,expressed to the nearest

one-one hundredth of one percent.
