16.4 Computation of the Annual Fuel Reimbursement Surcharge


(A) The Annual Fuel Reimbursement Surcharge shall be computed by

Surcharge shall be the twelve (12) billing Months beginning

the applicable subaccounts shall be increased or decreased

for a positive or negative change in Fuel Reimbursement for

the billing Month.

Quantities of Gas expended for fuel usage and lost and

unaccounted for gas reduced by Quantities of Gas retained

pursuant to Section 9.5 during the billing Month.


(E) Notice of Responsibility of Deferred Amounts


In the event this Section 16 shall be changed in any manner

that adversely affects Southwest's recovery of the full

amount of fuel amounts reflected in its deferred fuel

accounts, each Shipper that received storage service during

the period affected by such fuel adjustment deferred account

shall be responsible to Southwest for its proportionate share

of the amount of Southwest's unrecovered deferred fuel

amounts for the storage services which they were provided.
